THE CULMINATION OF THE HIGHEST PERFORMANCE AND DESIGN CHARACTERISTICS IN ANY SINGLE LENGTH IRON EVER DESIGNED.
/ / / PIONEERED BY WISHON GOLF TECHNOLOGY
Wishon’s single length iron design concept EQ1-NX offers same length and high COR low loft iron characteristics while adding many new performance enhancing features to mark a definite step forward in game improvement iron design.
-
-
Enabled by the new 2-piece hollow body design, the Center of Gravity moves progressively through the set from lowest and most rear located on the #5 iron to highest and most forward located on the GW and SW to achieve more consistent shot shape and shot height for each iron in the set
-
-
-
The hollow body design throughout the set increases the MOI of each head by removing all mass from the inside of the head to be distributed all around the CG. The hollow body construction also enables the CG progression and uniform impact sound between the high COR and conventional COR heads in the set
-
-
-
Low number irons are better matched with their loft to CG position to achieve preferred shot shape/height and allow a wider range of players to be able to effectively hit the #5 and 6 irons to fly and carry with proper distance gaps
-
-
-
Traditional GW and SW profile shapes are combined with milled faces and a custom sole grind make the wedges a great choice even if they were standalone wedges and not part of the single length design
-
-
-
275g head weight with hosel weight bore allows assembly to any single length between 35.5” and 37.5” while still being able to achieve a reasonable range of swingweight/MOI (depending on shaft weight and grip weight)

Available in RH in #5-9, PW, GW, SW, LW. Available in LH in #5-9, PW, GW, SW.

Hi Tom,
I am looking at re-shafting my EQ1 NX irons and I need to know if the shafts should be .355 or .370. I have 9 clubs to re-shaft. Do I need to order (9) 7 iron or 8 iron shafts. Or do I order a full set of shafts 5-PW, GW and a 54* & 58* and have them all cut to a playing length of 37″? Thanks.
TIM The standard bore diameter on the EQ irons is 0.370 parallel. You can ream out the hosels to accommodate a .355 taper tip if you have a 355 shaft that is at the top of your list to use. If not, I’d stay with a 370 shaft that fits you to your wishes. In that case if you get 370 parallel shafts, you would tip trim them ALL for an 8 iron installation and then install and cut to the desired playing length of 37″. Single length means every iron is supposed to be the same for everything except… Read more »
Hi Tom
I’m exploring a single-length build for my 14-year-old son and would really value your advice.
Player: Matt
• Age 14, height 5’5″ (165 cm), wrist-to-floor 33″
• 7-iron club speed 68–71 mph (using my 7 iron choking down)
Thank you
Peter Stone
Peter If you son has the interest to work at it, and the talent to become a good player with hard work, and if he is or will find himself playing more and more with others around his age, I don’t think that I would try to put him into a single length set. I’d keep him in the best fit incremental length set you can come up for his size, strength and swing characteristics. While deChambeau does play a single length set, after almost ten years of him playing at the highest level with a single length set, no… Read more »
Hey Tom, I am planning my order of the Eq1nx irons and planning to install the Kinetixx one shafts. They have 3 different kick point options for the high, mid and low irons. All same weight. In your opinion would this be a good option. Or go with two shaft profiles because of the COR heads and non COR heads. Need your professional opinion. Thank you!
ADAM If the reason you are considering the 3 different “kick point” options, I hate to rain on the parade but the only way that different “kick point” options can work in a set of irons is if, 1) you have a VERY late release with a very aggressive downswing tempo, and 2) you have a higher than average clubhead speed, like at least 80-85mph with the 7 iron. Let me explain more so you fully understand me and understand what’s going on. I ” ” the term kick point because it is one the most overblown things in shaft… Read more »
Hi Tom!
I’m a former customer, bought directly from your website years ago…. Single length set Wondering if that option is still available?
Arnie In 2016, we sold the Wishon Golf brand to Diamond GOlf International based in the UK. They have all of our former customer records so if you had a customer number from us from before 2016, Diamond should have a record of it. You can contact them either by email at sales@wishongolf.com or by phone at country code 44 + 1903 726999 to inquire and get set up again. If you do contact them, please do take the time to ask them to explain how the matter of the tariff increases will affect your ordering that the current administration… Read more »
Hello Tom, Hope all is well. When it comes to single length irons is total weight matching or swing weight matching more important? I have a used set of single length irons and oddly enough the weights differ by 8 grams at worst to a bout 4 grams on average (relative to the heaviest club). I added back weight to the center of the head to match total weight (within .2g). Now the swing weight variance is about 2 swing points either way. The original heaviest club swing weights to d0 and the old 8g light club D3.5 at the… Read more »
Julian The head, the shaft and the grip all have their own +/- tolerances in manufacturing. Grips can be +/-2-3 grams, Shafts can be +/- up to 5g. Heads are usually either +/-2g or +/-3g but because our heads have weight bores, clubmakers can always equalize out the head weights. Anyway, what I am getting at is that the only way a single length set could have all the irons be exactly the same for total weight and swingweight is if the heads weigh exactly the same, the shafts weigh exactly the same and the grips all weigh exactly the… Read more »
Hello Tom, I appreciate the reply. So in essence total weight can vary quite a bit due to all the compounding factors. Shaft weight has the largest impact weight wise but also the least impact when it comes to swing weight. The focus should be on swing weight matching to my preferred feel and be much less restricted by total weight. My thought process was that total weight for single length irons matter more cause there supposed to be more or less the same. With that said, I’ll be able to test a variety of swing weights at the range… Read more »
Julian Total weight will vary in a single length set due to the range in +/- tolerances. However, it won’t vary by a huge amount because the maximum in +/- tolerances for the shafts and grips isn’t really that much, as I outlined in my first response. If one club to the next varies within a range of say, 5 grams, or even 10 grams, that is really not a lot when it comes to total weight. IMO Rich Douglas is right – once you choose the shaft and grip you want to play, getting the swingweight right for YOU… Read more »
Fair enough. I ended up having the best results with the lower end of the swing weight testing range. Originally the heavier swing weights felt the best (just swinging them in the air before the range session). Testing found the lightest one was the best shot after shot. FWIW it was the 9 iron at C9.5, the others were mostly D1.7 and up. There was a LW and SW at D0.2 and D1.3 but you don’t really full swing them. The SW had a touch of lead tape added so everything was matched to it D1.2 (the lowest without any… Read more »
I vote swingweight. I don’t know how much a club weighs, but I do know how it feels, and swingweight drives that. When I had my Sterling–and then later my EQ1-NX–irons built, we focused on having the swingweights as close as possible.
Of course, that gets a little altered each time I regrip (and, once, re-shafted). But the measurements are within a half-point throughout the set, and it takes me at least 1.5 swingweight points before I really feel it. And again, if I can’t feel it, it isn’t there.
Hello Rich,
Good point. I ended swinging weighting them all the same. I did do this previously and had bad results BUT the clubs was very different. They had much heavier grips and they were longer. Normalized for the heavier grip they must have been around D6 or 7. Yikes!
Best regards,
Julian
Hi Tom, I have two questions for you… (hopefully not dumb ones)
1) The description says these are hollowed heads… can I soak them in a bucket of water to clean them? Or will water get inside them somehow?
2) I know other hollowed body irons heads (such as the TaylorMade p790’s) have a foam in them for sound and feel. Do the EQ1-NX heads also have a foam in them (or anything in them)?
Thanks!
BILL Hollow irons are totally sealed when the two parts are welded together to make the heads. There is no possible way that water or anything can get inside the hollow cavity inside the heads. We do not make the EQ heads with any type of foam material inside the heads because I felt in the design and testing that it was not needed. With some companies’ hollow irons, the body wall thicknesses and face thickness are such that without foam, the impact sound can be odd, different, unappealing to certain golfers. And the ONLY reason companies ever mess with… Read more »
In the original Wishon single-length irons, there was a perceptible “ding” with the 4-7 irons. I always assumed this was due to a different material (with a higher COR) in the face. (I rather liked it!)
It is gone from the EQ set, which (to me) feel like any GI iron (and better than most).
Hi Tom, I have been using the eq1 nx for a couple of years now and love it. It’s time for the loft/lie angle check in now. I’ve noticed some loft and lie are off from the standard loft/lie However, when I went to couple of local shop. Both of them said the iron is “very hard” to bend. And would dare bend it more than 1 degree. Haven’t able to go back to the clubmaker i fitted the club with. But the question would be. Is the +/-3 degree bendable most of the times? Or I should listen to… Read more »
EDDY The eq iron heads are invesment cast from 431 grade stainless steel. In the hands of a very experienced clubmaker they can be bent up to 3* in any direction. But the key word here is EXPERIENCED. There is no other area in clubmaking that takes as long to learn and gain proficiency in as bending L&L. The reason is because all these golf companies use a lot of different steel alloys and heat treatment procedures in making their irons and wedges. It takes a clubmaker who has bent thousands of heads of all different makes and models to… Read more »
Keep shopping. As Tom notes, they can be bent by an experienced clubfitter. Mine are 2 degree up and 1 degree strong. I’ve had them since their introduction and have had to have them checked and (a few) returned to spec.
Tom, the description above and your video only states that the SW and GW have milled faces and a wedge sole grind. Is there a reason why the LW wouldn’t include these attributes as well? Thanks!
Anthony
The Lob wedge was added later on to the model after the original set makeup was created that stopped at the SW. So this would be why I didn’t say anything about the milling of the LW face. But the LW is milled like the other two wedges.
TOM
Tom, with old age my clubs crowd a bit with my slowing swing speed even with senior shafts (Driver SS is 79) Yet I still want to walk and carry for 9 holes but that means fewer clubs. What is the impact of taking my eq1-nx irons (I have 8-GW) and making the gap wedge 52 (to serve as a dual wedge), pitching wedge 46, 9 iron at 40 and 8 iron 34 degrees. I would then use a hybrid 6. Do such adjustments mess up turf interaction or how you designed COG etc? Thanks
BOB
Bending the EQ 8 to GW to the lofts you stated in your comment would be just fine, it would not cause any problems or issues with the sole design or anything on the design of the head.
TOM
Thank you
Hi Tom
If you wanted to have 5-7 iron in standard 7 iron length and 8-PW in standard 8 iron length, would you need to adjust the lie angles?
Thank you
Tom, I’ve been using the EQ1-NX irons for about 3 years now. Quick question: what is the longest iron you would recommend based on a 70mph, 75mph and 80mph swing speed? I currently game the 5i, but sometimes it feels like the 6i goes just as far unless I jump on the 5i. My smooth swing is 75mph, a little extra is 78-80mph. Wondering if putting a SL hybrid in the bag is best for me. Any advice is appreciated. FYI, in my 7 or so years of playing SL irons, which I’ve played OneIron and Cobra and Sterling previously,… Read more »
RiCHARD Thanks very much for your post and for your question about swing speed vs set makeup for the single length set. It’s a great question because there most defintely is a guideline for what would be the lowest number iron a golfer should play, based on clubhead speed. First off, I assume when you talk about 70-80mph swing speed, you are talking about DRIVER SWING SPEED. If not, if your reference for 70-80mph is for one of the irons, please let me know quickly in a response to my post here. Every golfer swings the driver faster than the… Read more »
Just want to mention how these irons have completely improved my game. I decided to go single length while I was still trying to consistently break 100. I looked at several options but kept coming back to these. Now 6 months in with EQ1-NX irons 5 iron to GW and I’m closing in on the breaking 80 mark. I never believed I would be scoring like this, The feel of these irons is fantastic and of course the convenience of single length make these probably the only irons I’ll ever own!
TOBY
WOW!! 6 months into the EQs and you are on the verge of breaking 80?? How nice is that??!! I gotta say, you made my day with your post and I have to thank you very much for taking the time to stop by and let us know! I’ll be sure to share your post with everyone at Diamond Golf so they can also share in the enjoyment that you must have in the game right now. Wow. Keep it up!
TOM :>)
Hello, I am not super knowledgeable on the finer details about golf shafts, but I was wondering if you had any input on whether the claims made by e21 for their scandium shafts are true because their website lists a ton of crazy stats, but I haven’t really heard of anybody really using them. The website makes it seem like literally everything else is inferior, but I don’t know. Thank you for any insight! You can find their website I’m talking about by looking up e21 golf shafts, it’s like the first result.
TREY I remember years ago when the E21 shafts came on the market. I haven’t paid any attention over the past several years so to hear from you that they are still out there trying to keep selling the shafts does surprise me. Mainly because when they came on the market and I took a look at them, I could see that while the material was cool and could make a decent shaft, overall, the scandium shafts did not bring anything really new or remarkable to the industry that had not already been done IN TERMS OF WHAT MAKES A… Read more »
Hey Tom,
If I were to pull the current shafts S2S Black Stiff, what other shaft options are out there that will fit into the single length set-up?
TIM I apologize in advance if I am missing something in your question. If you are asking about the single length irons, any iron shaft with a 0.370 parallel tip will fit into the EQ1 single length irons. It is a matter of which shaft design best fits your strength and swing characteristics. The Black is a tip firm design chiefly intended for players with a semi late to late release of the wrist hinge angle on the downswing. The Red is another shaft suited for late release players although the Red with its heavier weight is for late release… Read more »
Hey Tom! First, thanks for being such an active contributor on your website, it’s super helpful to read the comments and answers straight from the designer. I am going to buy a test iron from Condor Golf to see how I get along with the EQ1-NX (I like to hit a lot of balls over the course of a few weeks to catch good days and bad, tinker with weight, loft, lie, etc), just looking for your input on specs to get as close as I can out the gate. I’m 6’2″, probably about 38″ wrist-to-floor, and my 7-iron speed… Read more »
Hi Tom, I have very recently received my new Wishon clubs following a fitting with Carla White near Warrington, UK. I live 150 miles away in Newcastle but the 3 hour return journeys were well worth the time, effort and petrol money! As a left-hander, I appreciate why I don’t have the same choice as righties but I am still very happy with the recommendations provided. I am the proud owner of a set of EQ1-NX irons (6-PW), a same length 5-hybrid to replace the 5-iron which I couldn’t hit, EQ1-NX 4-wood and 7-wood, 919THI driver (43.5″) and 309 wedges… Read more »
Pete My sincere apology for the delay in responding to your post. I was out of town for all of last week and didn’t have access to the comments section of the website. What a nice comment post for me to read though! And I am so pleased to hear that you chose to work with Carla. Carla has been one of my favorite pen pals ever since I had the chance to meet her at a British PGA technical seminar at which I had the honor of speaking that was at the PGA HQ at The Belfry some years… Read more »
Hi Tom, I have been using the iron set 5i-SW 37″ for the past year and loved it. However, I kept my 5i in the bag for most of the time as I can’t get it past my 6i. My average carry distances are: 7i: 160-170 yards 6i: 165-175 yards but my 5i result the same yardage as my 6i. I skipped to FW9 24 degree that result in 190-200 yards which the gap is sometimes too far from 6i Would you think that replacing the 5i with a longer/hybrid shaft a possible solution to solve the 5i gapping? And… Read more »
Adisorn It is a fact with ALL clubs that the lower the loft, the more clubhead speed is needed to elevate the shot high enough with enough ball speed and spin to keep it in the air to achieve maximum distance. In a single length set, the lowest loft irons will be shorter in length than they would be if the set were made to conventional lengths. This can also drop the clubhead speed for those lower loft clubs, which leads to my opening statement in this response. To effectively hit the EQ1 #5 iron with its 24* loft, a… Read more »
I played Sterling for 4 years and now the EQ1-NX since its introduction. In the Sterling set, I played the 4-iron. It was a great fairway finder, but a bit more problematic with approach shots. The carry was barely longer than with the 5-iron, but the roll out was longer…and sometimes too long. When I built the EQ1-NX set, there was not 4-iron. But there was, and is, a 4-hybrid. My experience with that club is that it fits the set’s gapping. It flies higher and farther than the Sterling 4-iron, and stops more quickly. This despite the fact that… Read more »
RICH Many thanks for the input on the 4 hybrid vs 4 iron. Sterling did teach me a lot about single length design that I tried to incorporate in the EQ1. A big part of it was deciding to do 3 hybrids so that we could have a higher flying alternative to the 5 and 6 irons, as well as a 4 to fill in that upper part of the set. It was really satisfying when we were doing hit testing on the EQ hybrids vs their iron counterparts to see how the lower and more rear CG of the… Read more »
Thank you both for your answer.
I Have contacted my fitter in Thailand to order EQ NX hybrid 5 to try out. Too bad im a leftie and there’s no demos for leftie here. We will try to work the hybrid with the orginal shaft from the 5i first and take it from there.
Question for RICH, you said they are the same specs. Just to clarify, they use exactly the same shaft?
Thanks!
Yes.
I wold like to add a 5 iron at least into my sterling set, but since they are discontinued i have look for other options.
Can you say if there is a loft for loft difference in distance, spin, trajectory between eq1 and sterling in lower lofts? I think coustics would be different – less clicky.
MK
The Sterling 5 iron was designed with a loft of 23*. The EQ1 #5 iron is 24*. Though a clubmaker could bend the loft of the EQ down to 23 if needed. Actually the launch angle of the EQ might be a tiny smidge higher than that of the Sterling because of the hollow iron construction of the EQ irons. And of course if you left the loft of the EQ-5 at 24* that would generate a very small increase in launch angle for the same swing vs the Sterling-5.
TOM
Hi Tom, thanks for your continued dedication to the single length cause.
I’ve stupidly used a flighted set of x100s in your EQ1 heads, rather than going identical shafts. Really should have read some of your answers first and not bought into the OEM flighted theory without some lateral thinking and proper research.
I’ve no idea whether I have a late release pattern or not but given I’ve a fast swing speed, what kind of miss should I expect from the flighted set, compared to matched?
Best and thanks
Andy
ANDY If one is new to the concept of single length, certin aspects can be a little confusing. It is best to think about single length as the irons all being the same club with one exception – the loft changes. Everything else, and I mean EVERYTHING ELSE, is duplicated on each iron in the single length set. If you have a set of shafts in the single length set installed all at an 8 iron length that vary in stiffness from iron to iron just like a normal incremental length set, it means that the shafts in the lower… Read more »
This is great advice , Tom. Thanks for your wisdom and have a great Christmas.
Andy
Tom , when bending an iron to change loft is it better to bend up or bend down, for those in between lofts? For a 58D EQ1, jump up the 55D or go down from a 60D?
Gary Very good question for sure and happy to help. The decision is based on how the change in the sole angle (bounce) would affect your play from sand, tall grass, thin lies, etc and so forth. Every time you bend loft higher in a wedge, you increase the bounce 1* for each 1* you increase the loft. And vice versa, every time you lower the loft in a wedge, you reduce the bounce by 1* for each 1* of loft reduction. So if you bend a 55 to 58, you increase bounce by 3*. In truth that is not… Read more »
What a great set of clubs! Bought these to experiment and they did not disappoint. The ability to comfortably cover all irons the same is a game changer. Having the same attack angle throughout the scoring irons is great. Same motion through the set. Got to figure out what I’m going to do for SW and LW. Single length is legit! Great product!
Dear Tom, I have had my EQ1-NX irons 5-SW for 3 weeks now. They were built to fit my needs by Geoff Waldon, as previously corresponded. The build quality is impeccable and to top it off I just hit 9 holes with a score of 39. For me that was a miracle. I would like to thank you Tom for being the total professional that you are and for designing and building the finest set of single length iron heads I know of. I really mean that from the bottom of my heart. Thank you sir. And thank you and… Read more »
KENT
I am so pleased to hear that your work with Geoff has resulted in such success for you!! That’s really tremendous to hear that. Keepo it up!! And if you see Geoff, please give him my best regards!
TOM
Is it possible to order just the heads for 5i and 6i? I’d like to build these 2 clubs the same length as my 7i. I am using srixon forged at the moment with steel fiber. Your thoughts would be much appreciated.
Victor We only sell our heads, shafts and grip and technology designs to clubmakers that we have screened and know to be knowledgeable and experienced in clubmaking and clubfitting. We do this so people who do not have the skills and knowledge would not build clubs from our designs that are not well made for each end user golfer. If you are a clubmaker with experience, we are glad to have the chance to work with you. If you are not a clubmaker we urge you to go to the FIND A CLUBMAKER link at the top of our home… Read more »
Is there a plan to retire the EQ1-NX and refresh it or replace it in the near future?
TRAE No. People who have followed my work since we founded Wishon Golf in 2002 know that my models stick around longer, far longer, than any other company’s models. It is very common for a model in the Wishon brand line to be around for ten years or more. It’s very rare when one is around for only 2-3 yrs. The EQ was intro’d in 2020 and was a re design of my first single length iron so that it incorporated pretty much everything that I learned from my first single length model that I hadn’t incorporated in that model.… Read more »
I appreciate the quick response. I knew that was typically the case but doing my due diligence because I am looking at replacing my beloved 560mcs that I built nearly 18 years ago. I tested out another brand of single length and was VERY impressed with the concept and how well it worked for my swing so naturally the plan is to build a single length set to last as long as my 560ms have.
Trae
Then you should find the specs of that other single length set (length, lie, shaft, grip, swingweight) and build the new set to match that, since you have such positive feedback from that set.
TOM
What’s the bounce on the wedges?
ROY
Bounce sole angle on the EQ PW is 6*, 10* on the GW, 12* on the SW and 10* on the LW. The GW, SW and LW are all milled face as well. And the GW, SW and LW all have the zero bounce heel which I created about ten years ago to enable players to roll the face wide open and not have the leading edge rise up off the ground to make it more difficult to hit shots off closely mown lies.
TOM
