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

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.  (page 82)

  1. 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.

  2. 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!!

  3. 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,
      TOM

  4. 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.

  5. 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!
