939AHT Drivers

Unique Adjustable Hosel Driver Design

The 939AHT is the most technically accurate and most versatile adjustable hosel driver in the entire golf equipment industry. The unique “top down” adjustable hosel mechanism allows for a greater range in custom weighting options for clubmakers while also offering a greater range in the final fitting specs for the loft, lie and face angle.

The weight bore for the 939AHT driver heads is located at the base of the adjustable hosel sleeve.  Do NOT drop a weight plug into the large bore of the body of the head


  • An all new “top down” locking mechanism for the adjustable hosel device that allows not only faster changing of the lie and face angle specs, but allows for a weight bore to be located at the bottom of the device for custom swingweight (MOI) assembly purposes.
  • Allows changing the lie from 56* to 60* and face angle from 2* open to 2.5* closed, when the 939AHT is traditionally soled in the address position.
  • Alternately, when the 939AHT is held in a 0* square face position at address, the lie can be changed from 56* to 60* and the loft changed from 9* to 13*.
  • Single rear weight screw can be altered from 2.5g to 16g to slightly customize launch angle, or to achieve final swingweight (MOI).
  • Available in RH in 9.5* and 11* loft, as per when the 939AHT is soled in the address position.
  • Do not forget to order a weight screw to go with each 939AHT.  Weight screws available in 2.5, 6.5, and 9 gram weights.  (page 82)

939AHT, 4.5 out of 5 based on 68 ratings


  1. Hi Tom
    A few queries:
    1. Is this a 460 cc head size?
    2. Is it a high MOI design like 919? What is the MOI?
    3. The spec. sheet is very confusing and hard to fathom for a lay person like me, with references to address position and 0 degrees position! To my uneducated eye, the driver seems to offer more fine tuning in open positions, which seems suited to a better player. But most of us ordinary golfers hit a bit of a fade and it seems from the specs that when you go to the closed positions, the hook angle and lofts crank up a lot, rather than in small increments. Is that right or have I completely misunderstood?
    4. I would like a driver with about 10.5 loft and 1 degree closed face angle. Can this driver achieve more subtle variations such as this?
    Thanks, Robert.

    • Robert:

      The 939AHT is 54mm face height, 110mm face width and 109 face to back breadth so the head is considered up there at the 450-460cc volume. MOI is 4920 g-cm2 for the head so that’s very similar to the 919. I realize it is a little different for us to list the specifications based on two different ways to address the ball. But this is how adjustable hosel drivers work. You can either set the head down to rest on its sole when you address the ball or you could hold the face manually in a 0 square position behind the ball just like you do with an iron. So that is the reason we list two sets of specifications depending on how you address the ball with the clubhead.

      Just because you see more positions that happened to end up open for the face angle when you set the club down to rest and sit on its sole does NOT mean this is aimed more at the better player. There are still closed face positions from 1.75* hook to 2.75* hook for any golfer who fades to slices the ball.

      If you want a driver with precisely 10.5 loft and precisely 1 closed face angle then you should order the 919THI in the 11 loft model and request for HAND SELECT SERVICE for us to hand select the head to have 10.5 loft and a 1 hook face angle. We have had the HAND SELECT service in the company for a very long time to be able to offer clubmakers more specific, more precise specs when they need them for a golfer.


  2. Hi Tom,

    Specification says loft can be adjusted and face angle is still 0*. Is this for real? as I remember reading your research on adjustable hosel that loft changing will effect face angle.

    Secondly, will you recommend using this head for fitting since face angle stay square on every possible loft and lie angle won’t matter when hitting off the tee?

    • NAVIN
      This is a VERY confusing part of the adjustable hosel drivers so please bear with me as I try to explain more clearly. Almost forever and ever, we golfers have been taught to use our driver and woods by setting them down on the ground first to rest flat on the sole. we sole the woods when we look at them in a golf shop and we tend to sole the woods on the ground resting flat on the sole when we start to grip the club to hit a shot.

      When you do that, the adjustable hosel device in EVERY adjustable driver only changes the lie and the face angle. The loft is always what it is in the actual head design. And as long as you always sole the driver head on the ground before hitting a shot, any change in the position of the adjustable hosel device will only change the lie and the face angle, and will NEVER change the loft.

      However, there are some golfers who for whatever reason, make it a habit to TURN THE CLUB IN THEIR HANDS to hold the club behind the ball always in a 0 square face position. Sometimes a golfer does this when he soles a driver, sees that the face is closed or open, does not like that, and so he then manually turns the grip in his hands until the face now is square. When you manually turn the face to be square behind the ball, in this case when you make the adjustable hosel position change, it will change the lie and the loft. it doesn’t change the face angle because you are manually holding the face in the square position.

      So with the 939AHT, all we are saying is that you can have two different ways to use the driver to get different specifications. If you always sole the driver head to rest flat on the ground on its sole, the change of the hosel sleeve will change the lie and face angle, and NOT change the loft. But if you are a golfer who always turns the grip in your hands so the face looks square always behind the ball, then in that case the hosel sleeve will change the lie and loft, and NOT change the face angle because you are holding the face always at the square position.


  3. Hello Tom,
    It is very interesting to read from previous comments that golfers can find you sheet confusing, whereas, to me, it is just the opposite : it makes the whole thing very clear. I think this is due to the fact that the OEM publicity about their own addjustable hosel never explains properly what really happens when one tweaks those hosels.

    • ANDRE

      Many thanks for your understanding of this matter. Yes, it has become very confusing for golfers. This is a situation where it becomes much easier to explain to a golfer if the golfer is standing right next to you, and you have the chance to show these things in person with the adjustable hosel drivers. But then I also know that you are without question one of the smartest people when it comes to golf equipment knowledge so I am sure you will always be able to make the golfers who see you able to understand these things!!!!

      TOM ;>)

  4. Will you be offering the 939 in white?

    • No we will not. The 939 will be offered exclusively in the black impregnation treatment surface finish with black paint and silver paint highlights. From our tracking and analysis, we see this year as likely the last year that WHITE will be popular enough for us to offer it past the summer of 2014 in the 919THI drivers and 929HS fwy woods. The whole industry is seeing a definite move away from white as a woodhead color so while companies that camped on it like Taylor Made will likely keep it as an option all this year and maybe part of 2015, the bet in the industry is that by 2015 while will be dead and gone as a short lived fad that grabbed some attention and then faded out.


  5. Hi Tom.

    I’ve been playing the 919 THI the last 3 years. TOO happy with it. The ball speeds of the face (even off center hits) are amazing. Will the ball speeds be as good with the 939 AHT?

    The reason I am asking is because on the launch monitor the OEM drivers are really inconsistant from one driver to the next (same brand and model). Will we see the same consistency in the new head as with the 919 THI?


    • In all of the robot hit testing with the 939 prototypes, the ball speeds were right there with what we see on the 919 for smash factors right at 1.48-1.49 which is right up on the edge of the limit. The 939 is being manufactured for me by the same foundry that has been making the 739. So since we see consistently high smash factors with the 739, I am confident we will see the same thing when the production of the 939 hits the steps for face forming and finishing. How we can do this on the 919 and our other drivers is mainly because we are so much smaller in size than the big golf companies. Because my orders for production are small, we can have the option of paying a few bucks more to have the foundry do ultrasonic face thickness gauge checks on each driver as it goes through its 5 steps in face forming and face finishing to make sure everything is closer to the design specs for the face. A big company can’t do that, not just because they won’t want to pay the extra $$ to have such checks done, but because even if they wanted to have this done at their foundries, their production quantities per order are SO LARGE that with the extra minutes per head this adds to the production time would multiply out to where they could not get their orders done in the timing for when they need them. This is one area in which it can be more helpful to be small so we can do some of these little extra steps that can make things a little more consistent for us in our production.


  6. Hi Tom,

    I am college golfer and am very interested in purchasing one of your drivers. I discovered your drivers while I was discussing a problem with the lie angle of my Titleist 913 with a friend. I find the lie angle on it, 58 degrees, much too upright for my preferences. He suggested your clubs for their variable lie angles.

    As for background information, I play 4 degree flat irons with X stiff shafts. My driver swing speed is above 110 mph and I average around 300 yards.

    I was hoping you could direct me to which of your clubs would offer the most “flat” look at address, which clubhead is best for a scratch golfer, and what shaft configuration you would recommend.

    Final questions. Would getting the shaft shortened an inch help promote a “flat” look at address? And, would the 919 FD be a viable option as a driver?

    Thanks, feel free to email me, and I look forward to your insight.


    • BEN
      Our model 919THI Drivers are all produced with a bendable hosel which allows us to adjust the lie and the face angle within a +/-4* range from the heads’ original design specs. So since our std lie on the 919THI driver heads is 58*, we can adjust the lie down to as flat as 54* if desired. One should never alter a spec like length just to get a certain “look” for the lie. You should be playing the length that is best for your swing characteristics and then getting the lie to be what you need for your size, stature, and swing. No other company is able to offer this much of a lie change on a driver (of fwy or hybrid since we have bendable hosels on those models too) because all other companies make their driver head body and hosel either from typical 6/4 titanium which cannot be bent, or they are using an adjustable hosel piece that cannot adjust lie as much as you would need and want.

      So if you go to one of the clubfitters on our FIND A CLUBFITTER locator search tool on our home page to be fit for a driver, you would tell him to order the head you need from us with the exact loft, lie and face angle you need for your swing and we will deliver it with each spec right on.


  7. Can I get the Driver with 55gramms on a longer shaft?

    • JOe:

      Yes of course. The 939AHT could be built with any shaft that is designed with a tip diameter of 0.335″. Within our custom design line of shafts, the shaft to meet your requirements would be the S2S Blue 55, but any company’s 55g shaft would work with the head as long as the shaft’s stiffness design were a good match for your swing characteristics. Our designs are custom built for golfers by independent custom clubmakers, so you would need to work with a clubmaker to be fit and have him custom build the driver for you. To find a clubmaker in your area, head to our home page at wishongolf.com and right in the middle of the page you will see a listing for our FIND A CLUBFITTER search tool. Click on that, input your town/city and how many miles you would be willing to travel to be fit, and the certified clubmakers in that area will be displayed with their contact information.

      Thanks very much,

  8. I am currently playing a Macgregor NVG2 driver that has a cup face. It’s about 7-8 years old. Will I see much difference with the 939AHT? I have tried several new OEM drivers but so far I don’t see any reason to change. I even had one fitter tel me that I hit the Mac better because I am more familiar with it and thus more confident. All of my clubs except this driver were fitted. I’m still searching for the right one.

  9. I have received the 939AHT Looked it over, envisioned scenarios with present customers. A few questions arise. I test all products, no matter who is the supplier. Without inside contact or major ‘box store’ purchase power, new tech is beyond my reach. So…
    Is the bottom of the sleeve, a ground to bottom measure? Doesn’t seem to be. why epoxy shaft? are additional sleeves the answer for shaft change? Extra trim for fitting? Is a sleeve available for other shaft diameters? will more options be available? And last, but not least, can upper handicap players get game improvement help? So happy to see and receive.

    • MIKE:

      the bottom of bore to ground dimension on the 939AHT driver is 1 1/2″. Most driver heads today have a BBTG dimension of between 1 1/2 and 2″ so this is very normal for the 939AHT. The sleeve is machined with a weight bore at the bottom of the shafting bore so the shaft tip stops 15mm above the end of the sleeve. This was one of the main reasons that I designed this head with a very different “top down” locking mechanism for the cap to secure the sleeve in the hosel. All of our head designs are created with a hosel weight bore at the bottom of the shaft bore so that clubmakers have the ability to add up to 9g to the head to help achieve the desired swingweight when each head is custom built to a different length or with a different shaft weight or different grip weight to fit the needs of each individual golfer.

      All adjustable hosel drivers, no matter what company makes it, will have the shaft epoxied into the adjustable sleeve device. When any golfer buys an adj hosel driver made by any of the OEM companies, the shaft is already epoxied into the sleeve. We design and manufacture our head models as component designs so the custom clubmaker is the one to do the job of epoxying the shaft into the hosel or sleeve in this case.

      The adj hosel sleeve is only made to accept a 0.335 shaft, which also is completely normal in the industry. While I do not inspect all the other companies heads, I do believe that the hosel sleeve devices on the vast majority of OEM adjustable hosel drivers are made to accept a 0.335 tip shaft. While it could be possible for a very experienced clubmaker with the right vice and reaming equipment to ream the sleeve of the 939AHT from 0.335 to 0.350 to accept shafts with a 0.350 tip, we really would not recommend that because such a reaming could throw off the very precise angle of the bore in the sleeve, which then would throw off all the different spec measurements when the sleeve is rotated into its 8 different positions. I doubt seriously we will make other sleeves for other shaft tip diams because there are way, way more shaft options in the game made with a 0.335 tip than with any other size tip.

      For higher handicap golfers who may need a more closed face angle to offset a slice or a more open face angle to reduce a hook (fewer high hdcps hook the ball though) the hosel sleeve can be rotated into different positions which will result in a slight to more dramatic open or closed face angle.

      But in all honesty, the 919THI driver stands as a better driver to achieve a far, far wider range of fitting options. In the 919 models with their bendable hosel we can deliver a 919 driver head in any loft from 8 up to 16.5, in any face angle from 4 open to 4 closed and in any lie from 4 up to 4 flat, with each different loft, face angle or lie spec delivered INDEPENDENT OF EACH OTHER. That’s something that NO adjustable hosel driver from anyone even us, can do.


  10. Just built the 949 with a Matrix 60 gr regular,44 “hitting it much straighter and further than ever..
    Tom you outdone yourself.

    • Thanks Tom! Coming from you with your experience in the craft, that is really nice to hear! The 939AHT does have a little “learning curve” in terms of its operation and assembly since it is such a different kind of adjustable hosel driver but once that’s over and it becomes a real golf club, we did figure from our development and testing work that it would be received pretty well for its performance.

      Thanks so much for taking the time to post and let us all know!!


  11. Hi Tom and TWGT,

    A few more questions and specifics about 939AHT. I was impressed with the quality, much more adjustable than expected, but have had a hard time with the echo/ping/contact noise. Not an issue, just thought I would relay mine and others opinions.
    The head was purchased as a gift for a family member. I really felt as he rounded into a better golfer this club would suit him and his game. He plays a 919 and really didn’t want a change. Things like women and work schedule have changed his avid pursuit of golf. Yah, I know, subject to change at any time.
    So, here is where questions and specifics make this a little more worth your time.
    A shaft epoxied into a sleeve similar to the hosel; is the sleeve heatable for shaft replacement without distortion? Removeable like a shaft from ahosel with normal cleaning? Are additional sleeves available to purchase? how much does GRT play a part in held 0 behind ball and grounding sole? I realize the vertical improvement, but seems a hand held may change the COG no matter the roll. So, you are specifying the back weight is that adjustment/
    A few reasons to fit for myself and still have a basis for my grandson. I love the adjustable scenarios.
    I guess I have shown my doubt in adjustable technologies.
    I won’t go into any more long stories. I have been at clubs for a while. Technology has surpassed me. I respect you and your opinion.


    Mike Underwood

    • MIKE:

      Thanks for your message and I am always happy to help. Yes, because the 939AHT comes with a 2.5 gram aluminum weight installed in the rear weight screw port on the head, it will offer a little bit more of a sound at impact than will our 919THI which is a completely “closed body” design with no “outer holes” to amplify the sound of impact. If, in the final weighting of the head to achieve your final desired swingweight, you were to use a heavier weight in the back screw hole rather than install the added weight down into the weight bore at the bottom of the adjustable hosel sleeve, you would find the sound dissipate. The weight screws available for the 939 are 2.5 aluminum, 6.5 and 9g steel, and 13g and 16g tungsten. As you use a screw made from a more dense metal like steel or tungsten, the sound vibrations inside the head from impact are muted much more than they will be if the 2.5g aluminum screw is left in the head.

      Since we now have the finished weight of the 939 head with sleeve and cap down to the usual 202-204g range, this means if you were building to lengths of 44.5 or shorter with a light shaft in the 65g or less weight range, you would need to add weight to the head to get it to a normal range of swingweight. If so, then you can use a 6.5g steel or 9g steel weight screw in the back hole, leave the hosel weight bore in the sleeve empty, and thus change the impact sound quite a bit.

      The sleeve is machined from 6/4 titanium. It can be heated repeatedly to remove any shaft that is epoxied into the sleeve with absolutely zero problem to the sleeve. In that sense, it is no different than if you heat the hosel of a normal TI driver head to remove a shaft. Cleaning is just like with any hosel – a wire hosel brush works fine or a Dremel tool with a stone grinding tip works OK to get the dried epoxy off the walls of the sleeve.

      Additional sleeves AND CAPS AND O-RINGS are definitely available. We are going to “chase the demand” for additional sleeves for a little while here as we did underestimate the demand for more sleeves and caps when we arranged the first additional production for these parts. But bear with us and we will have a completely adequate inventory in the additional parts before too long.

      The GRT has nothing to do with however the head is held or soled behind the ball. The GRT face design plays as intended no matter what the face angle you present to the ball. We’ve been making our driver heads with a GRT face roll design since 2004 so we have many, many, many driver heads in play over several different models that all have the GRT face design and so we know it plays very well to offer a little more consistent launch angle and spin when the golfer hits the ball from lower to higher on the face.

      When a golfer rotates ANY head to a 0 face position at address, the CG in the head only very slightly changes, not enough to really make any difference. By rotating the head to a 0 face when its natural soled face angle may be different, you do very slightly RAISE the CG in relation to the ball, but not by very much and never to a point that it causes any problems. Think about it this way. Let’s say you slice the ball so you set the hosel to a closed face angle position to help reduce that slice tendency and to keep that closed face, you do address the ball by soling the head in the address position. Because you slice the ball to begin with, that means some mistake in your swing is causing the face of a normal square face angle head to go from square at address to open at impact to cause the slice. Thus when you start with a closed face in the soled address position and you make your normal slice swing, this closed face now rotates during the swing to be less open at impact than if you started with a square face clubhead. As such that means during the swing you did rotate the head. So in the end, whether you are a straight ball hitter starting with a face you hold at 0 square, or whether you are a slicer starting with a closed face your swing then rotates less closed to the impact, from a CG standpoint you end up in such a close similarity to the ball that there is no difference in flight – of course as long as you had the loft fit correctly to your angle of attack and swing speed to begin with.

      I might add in total and complete honesty that IN NO POSSIBLE WAY can the 939AHT offer as wide of a range in each of the driver head fitting specs of loft, face angle and lie as can the 919THI with its bendable hosel. With the 939, you can get a reasonably wide range in loft IF YOU ALWAYS HOLD THE FACE AT 0 AFTER EACH HOSEL ADJUSTMENT. But if you need the face angle to be open or closed, then you have to sole the head to do that, and when you do that, the loft will be set in stone as to what it is on the head as it was manufactured.

      With the 919, since we have separate models in 9, 11, 13 and 15.5, that means within our Hand Select program we can hunt, measure and deliver any loft you or a golfer may need all the way from 8 up to 16.5 and in just about any increment of loft in between. Then we can additionally adjust the bendable hosel to any lie from 4 up to 4 flat and any face angle from 4 open to 4 closed – ALL DONE INDEPENDENT OF EACH OTHER AND ALL DONE WITHOUT CHANGING THE LOFT. So if you have a golfer who needs 8* loft, 3 hook, 4 flat, we can do that or any odd combination of loft, face angle and lie.

      That’s completely impossible with ANY adjustable hosel driver head.

      So the question you may have then could be “why did I design the 939AHT” if the 919 is a better fitting driver head? Mainly because we had so many clubmakers asking us to design an adj hosel driver to offer to their golfers. I like to think that we listen to what the clubmakers want. However a very big reason I did the 939 was to try to show the world that THIS IS HOW YOU MAKE AN ADJUSTABLE HOSEL DRIVER – what I mean is this. The OEMs did their adj hosel drivers and said they changed loft but they said NOTHING about how you had to always hold the driver in a 0 face position to get that loft change. And they said very little to nothing about the lie and the face angle or anything about what happens to the specs when you hold the face at 0 vs when you sole the head.

      So in doing the 939 to meet the requests of some of the clubmakers, I had to do it in a way that could explain exactly what it can and cannot do and how you have to work with the head to get whatever specs the head can offer. No question the 939 is a good performing head when you get it into the right specs for the golfer. But so is the 919 and when you factor in the vastly greater fitting options of the 919, it really is still the better head for a clubmaker who really wants to nail down any combination of loft + lie + face angle for a golfer and have all three of these specs to be what the golfer needs.


    • OMG! I honestly felt/thought technology would dictate a mass/much improved product/reward!
      Explanations aside, but OMG/WOW!
      I get it! and thank you!


  12. I want to get fitted but live in Charlotte, NC.
    Tom,can I get the same fitting that I would get if I visited you?

    • Roland

      Yes you can. In Charlotte you can either work with John Gamble at Carolina GOlf Mfg (704-563-0897) or with Curt Eudy at Leatherman Golf (704-527-1123) and be sure to get an extensive fitting analysis from a very experience clubmaker. Give them a call and talk about your current game and your areas that you are looking for improvement and then make your decision as to which one of the guys you may feel more comfortable with.

      Thanks very much for your interest !!!


  13. Tom- major manufacturers say that a clubhead that is 10.5* and 3* open, plays like a 9* driver dynamically when swung back to square while hitting a drive. Is this correct? Thanks

    • Dave:

      What you are talking about is this very nebulous matter referred to as “effective loft”. It really has become one of the more confusing areas of club performance since some of the companies have chosen to try to talk about it in such loft vs face angle terms.

      Bottom line is that if you get fit correctly for the right face angle to address any misdirection issues you may have, AND then you get fit for the right loft for your clubhead speed and angle of attack, this matter of effective loft takes care of itself and never, ever has to be thought about or considered when buying a driver. Give you an example of how this all takes care of itself.

      In a fitting session, the clubfitter knows that among all the 12 key fitting specs he needs to get right for each golfer are the loft and face angle. In a test club session, the clubfitter can start the golfer with driver heads of different loft to see what his launch angle and shot shape are. From that the clubfitter will find the loft that gets the golfer into the best launch angle and shot shape for his swing. If during these test sessions with driver loft the clubfitter sees that the golfer has a misdirection issue that requires a different face angle than is on the test head of correct loft, then the clubmaker can shift the test clubhead to one with the right face angle to address the misdirection issue. When hitting this test head to address the face angle, the clubfitter is also looking at that launch angle and shot shape at the same time he is observing the effect of the different face angle on the misdirection issue. If the clubfitter sees that now with the correct face angle the golfer’s launch angle is not quite where it needs to be to be optimal for him, then he knows he needs to shift the loft up or down to get back to that optimum launch and spin while also addressing the misdirection issue from the face angle.

      This is just not something that you can go out and predict when buying clubs off the rack on your own. You try a head with a face angle that allows you to have the most consistent direction. If the launch angle with that club is too low, then you get a head with that same face angle and a higher loft to get the launch angle right while still keeping the direction consistent. And if the launch angle with that club is too high, then you get a head with that same face angle and a lower loft to get the launch angle right. Doing it this way automatically takes care of that effective loft thing so you just don;t have to think about it.

      Hope this helps,

  14. Hi Tom,

    I had a wonderful conversation with Curt Eudy and will meet him next Tuesday to be fitted for irons.
    We talked about how to get that 16 hdcp. back down to an 8 or lower.
    Tom, what irons would you steer me towards for the fitting?

    Best Wishes!


    • ROLAND
      You certainly can ask and listen to Curt’s advice for the clubhead model since he will be working one on one with you. But when you tell me you are a 16 looking for improvement, I would suggest you take a look at the 771CSI irons. Hard to beat all the combinations put together in that one head design for distance plus off center hit performance, plus being able to be fit to virtually any lie requirements of the golfer and then all matched with whatever lengths, shaft, total weight, swingweight, grip size and set makeup that Curt sees you need for your swing characteristics.

      Thanks much and have fun in your fitting session !!


  15. Tom., a blast from the past I met you at golf works in the 80’s you taught the second course. I was thinking about buying 939 driver from you.Last time I talked to you were with Golfsmith at the. PGA show. I am the club repairman at Golfsmith in Sarasota,FL . Will be using 50 gram shaft at 44 1/2 long. I bought a set of 775 irons from Charlie Sampson last year. Took the job at Golfsmith in Jan. this year. Please shoot me price on this . It would be greatly appreciated.I am hoping to go to Golfsmith’s advance because I want to know more about MOI fitting that is the way my irons and 3 wood is set up. Thanks again in advance. Jim

  16. Hi Tom, just to say thank you for supplying me with the new Wishon 9.5 939AHT driver head which last week I had expertly fitted by Doug Holmes from Diamond Golf in the UK. As you know golf conditions at my Furness GC seaside links are usually wet and windy but that did not prevent me from testing this wonderful piece of craftsmanship. Without doubt the best looking driver design I have ever had the pleasure to use. It sits perfectly and it blasted its way through the conditions, but it felt like sunshine in my hands!! Thank you for hand picking the head and lie positions and all the correspondance with Colin Lord. I played some great shots (although just keeping my balance in the wind was an art in itself!) a lovely subtle draw and penetrative flight, just what i was looking for. This driver is weighted at the rear of the head and there are various weights to choose from too. An adjustable hosel for loft, lie and face makes this driver is a must. To those of you that are thinking about this driver, just wait until you actual see the finish and design . . . it will blow you away, as the saying goes. Thank you Tom and team.

    • Thank YOU Graham for taking the time to offer your comments about the 939AHT driver. I am so pleased to hear that the performance is good for you and especially in your more challenging playing conditions on your links!


  17. Is the 939AHT a conforming driver?

    • Kenny

      It is undergoing the process to be submitted for USGA conformity ruling. But I can tell you that it most certainly is and has been designed and produced to be conforming so I have no doubt when the USGA is done with it, it will be ruled conforming.


  18. Can you give me a description of the difference in playability between the 919 and the 939, and how to determine which one would be best for the golfer(me or someone else)? And how that choice is determined by the club fitter, other than just trying it out. If properly fitted, do they both have similar flight and distance characteristics?

    • Arvel:

      More times than not, the clubmakers tend to let the golfer make the decision for which clubhead model they wish to be custom fit in, especially with drivers. With drivers, to the consumer it tends to be more about the look of the head, how it looks on the ground with regard to shape features of the head. The rest of the process, meaning the determination of what loft, lie, face angle, shaft, total weight, swingweight, grip size – that part then is totally in the hands of the clubmaker to determine. and then to go through a test club process to verify that the specs are ok for the golfer and he’s happy with the direction the fitting is taking.

      For us, and I will be honest, I tend to recommend the 919 more than the 939. Reason being that with the 919’s bendable hosel, and with the 919 being tooled in separate loft models of 9, 11, 13, 15.5, that means we can hit any loft from 8 to 16, any lie from 4 up to 4 flat and any face angle from 4 open to 4 closed – and do that so each spec is secured on its own independent of the other specs. Can;t do that with ANY adjustable hosel driver because of the way all adj hosel drivers are made. The way they change specs is by changing the angle of the shaft into the head when the hosel sleeve is rotated. That means the lie and face angle are locked together and can not be changed independent of each other. So if you rotate the sleeve to get a face angle you need, it’s pure luck if the lie also fits the golfer too.

      Performance wise, the 919 and 939 are very similar for everything but sound. The sound of impact with the 939 is slightly higher pitched. This is because of the rear screw port on the 939 and partially because of the very large hosel bore that accepts the adj hosel sleeve. But ball speed, launch angle, spin rates are very close between the two when loft and face angle are the same on both heads.

      Thanks for your interest and I do hope this helps,

  19. Would it also be possible to get the driver head with a low and more forward CG to reduce spin?

    Thank you

    • Peter:

      It’s not possible to move enough weight far enough forward on the 939 to make any type of visible change in the spin characteristics of the shot. The one single weight screw port in the rear of the head comes standard with each 939 with a 2.5g weight, the lightest one we can make. We do have heavier screws to put back there either to just increase swingweight or to slightly/tiny/minutely increase launch and spin. But not lower it. In reading between the lines of your request for less spin, my experience tells me that in one part, this article I did for Golf WRX some time ago might help you a little bit – http://www.golfwrx.com/62891/the-practical-facts-about-spin-and-shaft-design/

      In terms of the head’s contribution to launch and spin, how this happens WHEN it happens is from the effect of the more forward weight mass on the forward bending of the shaft. More weight forward means less forward bending of the shaft at impact which means lower dynamic loft at impact to cause a little lower launch angle and spin. But this is a really, REALLY SLIGHT effect, and it only works for golfers who have a late-ish, to later to very late release coming into impact. Bottom line is that IF a golfer really does have a spin problem with the driver (read the article about this) then the very best way to reduce that spin is a lower loft on the driver head – not an attempted weight movement forward and not a stiffer shaft either. Hope this helps!!


  20. I am a 1st time user. 11 degree 939 AHT. I set up based on sole. I am confused as to how to read the Hosel positions when looking at the club as it rests in a playing position ( head on the ground and shaft upright) . I don’t see a line that tells me what position I’m in. Is my point of orientation, a) the top of the club head or b) the strike line on the face of the club?

    By example, when received, the club when addressed at sole position (head on the ground and shaft upright), the hosel reading as viewed from the top is 1, if viewed from the face it reads 8 ? Which is the correct way to read the hosel setting?

    2nd Q after hitting a few I want to adjust the setting to 6 – where do I line up the 6 visually – Top of club or face?

    3Q – Not being a club maker, I do not know which way to turn the wrench to loosen the hosel to make the adjustments. I know left is lose and right is tight but is that based on the head sitting on the ground or flipped with the head in the air? I do not want to break any thing so please advise.

    Help !


    • FRANK:

      Happy to help as much as possible. I’ll try to do my best with typed words. The cap has left hand threading so the direction of tight vs loose is reversed from what you are used to with normal screws that all have a right hand threading. From your comment it does sound as you know the correct direction of rotation for the cap to loosen it vs tighten it. You do the operation of loosening or tightening the cap most easily with the grip on the ground and the head in your hands. And then once you have the hosel sleeve in the position you wish and the cap is very tight, then you can go on to use the club and never have to think about it again unless you wish to change the sleeve position again.

      On the hosel sleeve piece that is epoxied to the shaft, you will see a small vertical line that is engraved on the sleeve in a direction along the length of the sleeve. When moving the sleeve into a different position, you align this line on the sleeve with the number that is on the very base of the hosel of the head. The sleeve is made with little flat edges that fall into place with flats that are on the inside top of the hosel. So when the sleeve is inserted into the hosel so this line on the sleeve is in line with the number on the base of the hosel that puts the sleeve and shaft into the proper position for each hosel number position. You only align the line on the sleeve with the numbers on the base of the hosel. You do not look at the face at all in any of this position change for the sleeve – you ONLY align the line on the sleeve with the numbers on the base of the hosel.

      I assume that you do have the printed information brochure that we ship with every one of the 939 heads. This explains what the loft, lie and face angle will be for each hosel number position AND it also explains the specs for each hosel number position when the golfer SOLES THE WOOD ON THE GROUND vs if they choose to always rotate the head to hold it square behind the ball at address.

      Hope this helps, but we are here of course to help more as you may need it. If you need further assistance, you can email us at contact@wishongolf.com or call us at 800-470-0072.


  21. Hi Tom

    Just wondering why this has been discontinued so soon after its launch? Has it just not sold well and /or not been embraced by club – makers/fitters?

    I have one in 9.5 degrees and use it in position 7. However, I am having lessons and as my swing and shoulder turn improve, I expect to move it to a less closed position – indeed I am on the verge of moving it to position 8. Which for me is the USP of this club – it allows for player improvement. The 919THI can’t do that without trips back to a club-maker to be adjusted, which is both a pain and added expense.

    And the 939 performs every bit as well as a 919 as to launch, distance and forgiveness. So I am a bit baffled!

    Regards, Rob.

    • ROB

      I appreciate your comment, your concern and your questions about my decision to discontinue the 939 driver models. While the big companies rarely keep a model for more than 1 year before dropping it to bring out the next one, we here have typically kept models in our line for sometimes as long as 10 yrs, with the average being around 5-6 yrs before we retire it. So it is unusual for me to make this decision on the 939 as we headed into its third year of existence.

      I made this decision for several reasons, most of which were related to my passion for the priorities I have in my work in clubfitting technology as well as in head design technology. No question, once you fully understand how an adjustable driver like the 939 has to be used (soled or held square) to get the specs you need and want, it is possible when your fitting spec needs do change that you could re adjust the setting on the 939 to change to the different face angle you would need after your swing change. And yes, to do that on the 919 would require someone to do the bend on the hosel to get that face angle change, which I do understand is more of a hassle than with the 939.

      It is a fact that while you bring up a VERY valid point with respect to making the specs change on the 939 when you do make it through a swing change, this is something that in all honesty does not happen very much with very many golfers. The vast majority of golfers just don;t change their swing characteristics to the point that a major spec like the loft or face angle or lie would need to be altered once the original fitting is done. But please do understand that I do realize when that does happen as you envision it in your swing, it would be easier for you with the 939 than with the 919 that would require sending us the club or finding a clubmaker with the proper equipment to do that.

      I simply am operating from the point that the 919 offers such a wider range in loft, lie and face angle specs, all which can be achieved at the same time, independent of each other on the head. 939 cannot do that. Also, it was a fact that by far, the vast majority of our clubmakers were opting for the 919 for these reasons so not that many clubmakers were interested in the 939. Performance wise, no question the 939 is as good of a head for launch, distance and forgiveness as the 919 – but with so few of the clubmakers wanting the 939 vs the 919, this too was another reason for my decision so we did not hamstring the production quantities of both driver models to make it tougher to manage the inventory properly.

      Thanks for your understanding.
