939AHT DRIVERS
THIS PRODUCT IS NOW DISCONTINUED
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
Features:
- 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

Hi Tom, I realise this model is discontinued but one of these heads has come up for sale and I’m intrigued by the complexity of it, especially after watching your videos. I have a couple of questions:
1) Is it legal to use?
2) Is the shaft glued or is the hosel fixing a compression fixing?
Thanks Rob
ROB Happy to help you with more information. 1) yes, the 939 is legal and was always designed to be conforming to the rules. 2) The shaft is epoxied into the special hosel sleeve, then the sleeve with the shaft is inserted into the hosel to achieve the optional desired combination of lie + face angle or loft + lie. This was a more complicated design because we offered very in depth explanations of how the rotation of the sleeve could achieve a variety of different specs. If you are serious about buying it, please do take the time to… Read more »
Hello Tom I have managed to buy a 939 AHT DRIVER second hand with the wonderful red shaft and it has already improved my driving consistency. Unfortunatly it did not come with the wrench or any alternative rear weights and have been unable to find a spanner that fits properly so am unable to ascertain what setting the shaft is set to. I have contacted Diamond Golf here in the UK to see if they had any spares in the inventory they took over from yourself with no luck. Would you happen to have any of these small items still… Read more »
Nigel Thanks so very much for your kind words of support and well wishing now that I have decided to retire after working in the golf equipment industry for over 35 yrs. And I guess I am not fully out of it since I am still helping Diamond Golf in their takeover of the responsibilities of distributing my product line! I am sorry but last year when we were going over everything in our warehouse and inventory to pack and send to Diamond Golf, there were just so many odds and ends from years of doing this that we just… Read more »
My 939AHT broke and was replaced with a 919.
So I have a spare wrench and a weight (the weight has white colouring and my kitchen scales say it is 10g).
The wrench got slightly distorted in the spanner bit and could do with tapping back into shape but did still work.
I am happy to pass these on – I live in UK. If Nigel lives in UK I will post FOC, but will obviously need his details.
Regards, Rob.
Hello all. Thanks for your replies. What a coincidence though as just after Rob’s reply offering me the wrench, etc, as his 939AHT had broke, then my next round with the driver and with the first hit….twang and on inspection the head has cracked around the base of the hosel. I have some photos Tom if you wish to inspect them as this is the first time I have had a head crack like this. I do not have a fast, agressive swing….around 90mph with a smooth tempo. Shame as I really liked the feel and look of this driver.… Read more »
Nigel – wipe out! I loved everything about my 939AHT (the head shape, looks, sound, adjustability, ball flight etc. The replacement 919THI is also a very good product, although I do wish it had kept the original SP700 face rather than downgrading to the less expensive 6-4 titanium – Tom will doubtless say it has no performance difference, but my recollections of SP700 (from a Cleveland Launcher Comp and a Titleist 905R) is that it had great feel and sound and a certain “springiness”, none of which 6-4 seems to me to be able to match. But I digress! Anyway,… Read more »
Hello again Tom.
Just to finish off this thread……the vendor I had purchased the 939 AHT from gave me a full refund and I now have an 11* 919THI which is proving just as good, if not better than the 939. The better consistency I am now achieving using your clubs from tee to green has resulted in a drop in handicap from 19 down to 12 over the last few months……concentrates the mind somewhat!!
Thanks again.
Nigel
NIGEL:
That’s great to hear, both from the standpoint that you got the 919 as a replacement for the 939 and that you are playing much better than before ! That’s really nice for me to know the game is more fun for you these days ! Thanks much for your support and for letting us know how well you are doing these days in the game !
TOM
About to change my driver, used a Ping Draw G15 for the past 4 years, it has 12 deg loft and a soft shaft, alas it looks a bit tired. I am about to bid on a Wishon 939 AHT with an Accra Senior shaft 11 deg loft. I am 77 years old, golfed for 50 years. I live in the UK Gloucestershire, is there a qualified fitter in my location that could adjust where neccessary? The asking price in the eBay auction is $150 plus postage, which I think is fair for a high quality driver. My swing speed… Read more »
JOHN: Thanks very much for coming to our site so we could advise you. Do NOT get that 929AHT driver. It won’t have enough loft for your 75mph swing speed. Better for you for that speed would be a loft in the area of at least 13 to even possibly 15*, depending on your angle of attack into the ball. In your area we would recommend that you contact one of the following clubmakers to work with to be custom fit so the driver is well matched to your swing now.

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… Read more »
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… Read more »
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… Read more »
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… Read more »
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… Read more »
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… Read more »
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.
TOM
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… Read more »
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!
TOM
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… Read more »
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
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… Read more »
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… Read more »
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 !!!
TOM
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,… Read more »
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… Read more »
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!
Mike
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
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!!
TOM
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… Read more »
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… Read more »
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.
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… Read more »
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… Read more »
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… Read more »
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?
Regardt
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… Read more »
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… Read more »
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… Read more »
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… Read more »
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,… Read more »
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… Read more »
