SINGLE LENGTH IRONS
Wishon’s new 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.
Features:
-
- 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
Are updating your single length irons soon?
Ian
Nope. I updated the first single length iron design I ever did (Sterling) when I designed the EQ1-NX and did everything that I learned from the Sterlings that I needed/wanted to do. So there is nothing I can do better on the EQ1 clubs so it will remain as it is for a long time, I suspect. Thanks very much for your interest,
TOM
Is it possible to buy just the heads 6-PW? I like building my own clubs.

Tom, I have the EQ1-NX 6 – 9 irons hand picked at 275.5 grams giving a swing weight of D0.7, however, the 9i although marked at 275.4g was actually 278g. I am looking at adding an 8g counter weight which will lower the swing weight from D2.0 to D0.4. Is there any performnce difference than if it had come in at the ordered head weight of 275.5g?
RAY First of all since you requested and paid for a hand select for weight, you should contact Diamond to tell them what you got and have them send a replacement that you ask them to actually weigh instead of picking it by the weight on the sticker. I am sorry for this, normally the factory doesn’t make this mistake. But really, since you paid to have the head weights the same, you should get that. To answer your question though, I am not a fan of counter weighting simply to trick the scale into reading a particular swingweight. When… Read more »
Tom, I had ordered other clubs Diamond before with weight requests and lie angle changes being executed perfectly so I have good faith in Diamond. I will have my clubmaker contact Diamond for a replacement- very interested in your comments on counter weighting versus accepting the higher swing weight as I had wondered about this issue before.
Thanks.
Ray
RAY The matter of ending up with a swingweight that is higher than what you want in the assembly is a big problem with no good solution. It’s easy to add weight to a head but very difficult to remove weight from a head. In fact the only way to remove weight from a head is to grind it off. With cast stainless irons that are polish finished, as long as you have proper buffing wheels and experience doing that, you can grind weight off and restore the finish so everything is good. But if the head in need of… Read more »
Tom, if one were to add 2 grams of head weight to one the heads in a set of EQ1s for swingng weight matching would the overall mismach with the balance of the set be the same or to a lesser degree than the counterweighting in Ray’s situation. Thanks.
Bill
BILL
A 2g change in head weight is so small that very, very few golfers would ever notice the difference before or after that small of a weight change.
TOM
Hi Tom,
I just purchased a used set of EQ1s. They are all standard loft and lie but would you recommend I still go get a custom fit? If so, is it preferred to get fitted at a Wishon club fitter or would any reputable club fitter be able to perform a proper fitting?
Hawkins
Any clubmaker would be able to change any of the specifications of the irons. What you need to be cognizant of in whether the irons fit you would be the length, the lie angles, the shaft model/weight/flex, the grip type and size, the swingweight. Any experienced clubmaker should be able to analyze you and address those things.
TOM
As they say in London at Underground stations, “Mind the Gap!”
You should also pay attention to the carry distances you get with each club, considering whether or not you need to tweak any lofts to maintain proper gapping between clubs.
Otherwise, I echo Tom’s point, and pile on by saying it is critical to have any set of irons properly fitted to you and your game (along the parameters he mentioned).

Hi Tom, I own a set of EQ1s (H4, H5, … LB) with which I am very satisfied. I started playing golf 4 years ago at the age of sixty and not having to worry about changing my swing plan for each club has greatly helped me progress. I have now a handicap of 25 and am very happy to play with these clubs! Well, the other players look at me a bit like they’re from another planet, but it makes for some fun conversations. .. I have a question, here in France a club maker offers to make a series… Read more »
Meyer Congratulations on just starting the game at the age of 60 and doing so well with it now! For your information the EQ1 #5, 6, 7 irons are made with a high COR face while the #8 to wedges are made with a conventional steel face. I use the high strength steel in the lower loft irons to help increase ball speed in the clubs that normally would be longer in a conventional incremental length set. Then in the 8 to wedges there is no need to have the thin high strength steel face. So the EQ1 irons now… Read more »
Hello Tom,
Does the difference between high COR and conventional steel explain the difference of sound between #5, 6, 7 irons and the others?
Best regards.
Étienne
Etienne Most people tell us they detect no real difference in sound between the 5, 6, 7 and the 8, 9, P, G, S irons in the EQ1 set. In the old Sterling iron set where the 4, 5, 6, 7 were high COR thin face and the 8-wedges were conventional steel like the way the EQs are designed, more people did note the impact sound difference because the Sterling irons were a conventional open back cavity design. The EQs are a hollow body design. So the hollow body captures most of the impact sound difference between the thin high… Read more »
Hello Tom,
thank you for your answer. That’s strange: I hear a real difference between the high COR and the conventional steel. It’s hard to describe but I would say that the sound of the 5-7 irons is higher.
Whatever, it’s not really important and all irons are so enjoyable!
Amazing work!
Étienne
I’ve played both sets. The Sterling had a distinct ping in the high-COR clubs (4-7) for the reasons Tom mentioned. The EQ1-NX does not. At all.
Hi Tom, I don’t know if I’m even about to ask my question correctly, but here goes nothing.. The EQ1 heads are made out of 431 Stainless Steel… Is the bright mirror finish merely a highly polished stainless steel, or is there a layer of nickel or chrome on top of the stainless steel that gives it that bright mirror finish? As for the cavity portion of the club, can you elaborate as to what’s going on there? Is it stainless steel that has gone through some sort of process to ‘roughen it up’ with a coating of sobe sort… Read more »
ROB 431 stainless is almost never, ever plated because it is almost always passivation treated at the factories to fully prevent any possibility of rust forming from outside pollutants that may come in contact with the heads. Thus the conventional mode of finishing any 431 head is through polishing, which can be done in different finishes including mirror polish. So the shiny finish is simply polishing of the surface. All mirror polished stainless heads will dull out over time, a condition which most golfers just live with when it happens. However, there are a handful of companies in the US… Read more »
I read and have been told numerous times that an incorrect shaft flex could lead to too much (or too little) lead bending, resulting in more slicing (or hooking). Is any of this true?
Thank you!
MARC The belief that an incorrect shaft flex could result in more slicing or hooking is very, very over exaggerated and not really true. If a golfer uses a much too flexible shaft, ONLY IF HE HAS A LATER TO VERY LATE RELEASE can the shaft come into impact curved forward more than if the shaft were not as flexible for the golfer’s swing. Early to midway release players experience the shaft completing its forward bending BEFORE impact so by the time the club gets to the ball, the shaft has rebounded back from being curved forward. But thanks to… Read more »
Hi Tom, I have been playing EQ1 from wood to PW. n Micro-Groove HM wedge. But i just dont know why i love the feel of Micro Groove HM wedge. Its Traditional length. I feel controlled n hit my AW (52°} bout 115m easily with high loft. My 7iron bout 150m gapping i feel still ok. I even ask my fitter what other set which the head is similar to Micro-Groove HM as i love e feel of it. I feel the weight of my wedge is gd, i feel the head. Thus i seeking advice should I reshaft my… Read more »
TAY You have to be careful in making the assumption that duplicating the swingweight of the HM wedge in your other irons. You did not say what the length and swingweight of the HM wedge is, but I must assume that it would be higher than normal because the headweight of the HM AW is heavier than the head weight of the EQ1 at its 36.75″ length. The headweight of the HM AW should be around 284g and the length is probably shorter than the length of your EQ irons, bu I do not know if you added any weight… Read more »
Hi Tom, I play the eq1-nx do you know anywhere in Ireland or even the UK I could order a replacement 9 iron stiff and a replacement stiff shaft for the 8 iron, Thanks
Shaun
Please contact Diamond Golf on 1903 726999 and ask to speak with a member of the technical staff, either Doug Holmes or David Edwards. Tell them what you need and they will figure out the best way to get that done for you.
TOM
Please, what is the shortest length that the Wishon driving 3 iron could/should be made to? All driving irons seem to have longer shafts and I have a set of EQ1 irons. I struggled a little with the eq1 4 hybrid for consistency and would like to have as short a utility iron as possible, hybrids just go left for me too many times. I appreciate the physics and why the irons only go to 5, but could the 3 iron driving iron be made to say 6 iron length? Many thanks for any advice. Tom
TOM Every golf club ever built has to have a HEAD WEIGHT FEEL when swung that can match well to the strength/tempo/rhythm of the golfer’s swing. Too light of a head feel and the golfer swings too quick, moves around too much, ends up with very inconsistent ball striking results. Too heavy and the golfer struggles to swing within his best timing and rhythm as well. What the right head feel for any golfer ends up being can pretty much only be determined by trial and experimentation with a test club built to the golfer’s best/desired length, with the right… Read more »
Fully understood. Thank you for putting that data up, it makes it much clearer now. Really appreciate the knowledge and time taken as always. Thank you.
Is there a reason why you build your irons with little offset, as opposed to the companies who sell game improvement irons with offset up to 6mm? Is ”offset” something that can help a golfer?
MARC Having begun designing clubheads in 1986, I have designed and tested a whole lot of iron models with offset. For a long time I used to design almost every game improvement iron model with offset. About 2010 I decided to only do a progressive offset on game improvement irons, which was when the lower number irons had more offset, progressing down to very little offset on the wedges. But then about 3-4 years ago I called it quits on offset and vowed never to design an iron with more than 2mm of offset ever again. The reason is because… Read more »

TOM
Tom, I played the sterling sat you designed and then converted over to the EQ1’s as soon as you released them. I’ve been very happy with the EQ’s and I’m thinking about building a bit of a combo set. I was thinking of keeping my Vokey wedges in a 60, 54, and a 48. Then building the EQ‘s at two different links. Keeping my current eight iron length from pitching wedge to eight iron and then building the seven iron through five iron in a slightly longer same length version. Have you done any testing this way? And will it… Read more »
STEVE While a big reason for single length is the fact that all irons of the same length would have the same MOI. swingweight, swing feel to accentuate shot/swing consistency, you can do what you propose as long as you take the time to build the clubs in the different length groups to have the same MOI. That would require the use of an Auditor MOI measurement machine though, to do that right. But yes, it can be done. In my set, I have the 8 to SW all the same 36.5″ length and then my 7 and 6 irons… Read more »
Hi TOM,
I want to go to your single length irons. I was a HCP24 player 15 years ago before I stopped golf and now I’m starting back as I’m retired. My swing needs quite a lot of rework… I was wondering if I should change right now or wait to get a fitting with the new irons when my game will improve.
Thanks for your help.
Daniel (from France).
DANIEL It would be best as you get back into the game to go ahead and start that journey with the single length irons so your swing and set up position work can adjust and learn and accommodate using irons that are all of the same length. In fact, it may very well be that with all the irons the same length, you ay find you learn the new fundamentals of the swing better and sooner since all the irons are the same. As you keep working on the swing, you may find over time that a few of the… Read more »
Thanks TOM, I will go to golfnswing clubmaker near Paris.

Hello, I’m having difficulty finding a Wishon fitter near me. I found a used set of EQ1s that are priced well and I would like to give one length a try. I know I can have a local club maker bend the lie angle on the clubs if I need it. My question is more about the shaft model and length. These irons are 36.75″ S2S Red shafts. I’m 33 years old, 6’5, and big/athletic. Still getting into golf, but I typically hit my 9 iron about 150 – 155 yards. Without driving the 4-5 hours it would take me… Read more »
Joshua The Red shaft is designed for golfers with the following characteristics – 1) The Red shaft weight is heavier so that works better if you are physically stronger than average; 2) The Red shaft is designed with a stiff tip section for players with a more aggressive downswing tempo AND with a very late unhinging of the wrist cock angle; Being 6’5, 33 and able to hit a 9 iron that far, you sound like you definitely would have #1 covered. Then the question would be whether you have a very late release to handle the stiff tip design.… Read more »
Hi Tom, I sent an e-mail just now but I see you’re pretty responsive on here so I’ll drop the question here too. Looking to re-jig my entire bag and would love a complete set recommendation. My local (2hrs from me) Wishon fitter is abroad for the next couple of months so I have nowhere else to turn. Height: 5’6″ Wrist-to-floor: 31.5″ 7i Swing Speed (-0.5″): 84mph 4-hybrid Swing Speed (-.05″): 89mph Driver Swing Speed (-1.0″): 96mph Looking for everything from Fairway woods, hybrids, and irons (excluding GW,SW,LW). I’d like the irons and hybrids to be the same length and… Read more »
BRIAN
Happy to help but I need a little more information if you would please. What is your handicap/avg score? What is your swing tempo – smooth, average, aggressive, very aggressive? What is your missed shot tendency both with the irons and the woods – misdirection, contact, shot height/curvature, etc? What is your strength, age and athletic ability? WHat is your swing plane – upright, avg, flat? When do you unhinge the wrist cock on the downswing – early, midway, somewhat late, very late?
And are you mostly interested in the EQ1 irons AND woods?
TOM
Tom – my EQ1s are bent 3 up to 66. Even with that my iron strikes are 4-5 degrees toe down. I’m sure it’s a swing technique issue. That said I’ve got a set of Arias 23 irons I’ve had bent 6 upright from standard, so wedges are 70 degree lie angle. On the launch monitor (GC Quad) the strikes are close to flat (ie toe is not down). Lining these clubs up seems a little tricky in that my hands need to be forward and face needs to be consciously pointed right. Anyway, curious of what you think of… Read more »
PAT I only recommend bending for lie fitting based on what we call the “ink line on the back of the ball” technique. Not a lie board. And not really any launch monitor data either. What you want in a perfect lie angle is that at impact, you want the line of the sole from toe to heel to be as level to the ground (level ground) as possible. No toe up and no heel up. The ink line fitting technique finds that lie for the iron perfectly. Here’s how it works. Using a Sharpie pen, you put a thick… Read more »
Hi Tom – I really like the EQ1 irons and when I flush a 5 iron it goes the same length for sure as when I flush a regular length 5 iron. However, I struggle going to longer shafted hybrids and then to 3 wood and driver. I have already shortened the 9-SW to regular length but have 5i to 8i all at 8i length and the 4 hybrid at 7i length. I really like the heads and the feel when you hit one well and probably a lot of my issue is not playing enough golf such that I’m… Read more »
TOM When you say “change these to std length all through” are you talking about std length being the norm of half inch incremental length changes between each iron, or are you talking about std length making all the irons + hybrids to be the same 8 iron length? The latter would be hard to do since the head weights of all the EQ irons and hybrids are the same so they could all be made the same length or within a half inch thereof. If you are talking about making them all a std 8 iron length so they… Read more »
Thank you very much indeed for your detailed reply. It’s always very much appreciated to receive your advice.
Hello Tom, I currently have four clubs in my bag that you have designed, and I love them. In the coming days, I will be testing the EQ1-NX irons with club fitter Stan Moravia, here in northern California. I am very excited to try them. Currently I play my 8-iron at 35.5 inches length and a lie angle of 59 degrees. Based on the club specs and comments you have made in this forum, I know that I can get the EQ1-NX irons built to match this profile. There is a possibility that I might want the clubs built to… Read more »
Seth I am thrilled to hear that you are going to be working with Stan. He truly is one of the very best clubmaker/clubfitters I have had the pleasure to meet and get to know over the years. And in his case, it’s fun because many years ago I lived in Marin when I was just getting started in the golf business. I go way back to the days when the driving range you went to off Smith Ranch Road was Las Collinas and not McInnis Park!! HA! The guideline for minimum length for the EQs is based only the… Read more »
Tom,
My question is about the history of shaft length for incremental clubs (variable-length clubs)
I cannot find any information on this.
I will appreciate it if you can help
Johan THat’s a very good question and one that I do not have the absolute, clear answer to. I can tell you a few things from my many years of researching old golf clubs but I don’t have the definitive answer. From the time the game started in the late 1400s until the early 1900s, golf clubs were only made and built by individual craftsmen, relying on local sources for the materials and means to actually make the clubheads and shafts and grips. There were no golf companies per se until the very late 1800s to early 1900s. A community… Read more »
Tom,
Thanks for your response, it certainly is really useful. I find your statement ” So the first “standards” for club length were simply determined from what the clubmaker remembered were the most common lengths by average that he had built for numerous golfers over the years.” very interesting. So the variable lengths were based on the single-length custom-fitted for players of different sizes.
Thank you once again.
Kind Regards
Johan
Johan Most of the specifications for golf clubs were established first by trial and error by clubmakers who made hundreds of sets of clubs and just remembered how they made them for the different golfers. Then when a new customer came to the clubmaker, the clubmaker would note his size, strength, ability, and refer back to clubs he’d made in the past for a golfer who was close to the same in these areas. Over time, that’s how most of the club specs evolved. One of the fascinating ones was the FLEX of a shaft. Making the shafts to different… Read more »
Hey Tom, question about distance dispersion.
I’ve been playing EQ1-NX irons and hybrids for a couple seasons, love them. This year, my ball striking has made drastic improvements, and as I’ve gotten much more accurate left/right, I’m noticing more than the occasional “hot one” that flies an extra 10-15 yards.
I’m curious if this has to do with the hollow body design, and if so, would I benefit from switching to a more traditional 1-piece forged club?
Matt There can be a few reasons for an occasional “hot one” but it is true that in any iron that is made with a less than thick face, meaning both high COR face irons as well as hollow irons with conventional steel material for the faces, it can be possible for conditions of the path and angle of attack and point of impact to result in the face being flexed inward a little more. And that in turn can increase the ball speed, which increases the distance for that shot. ALso factoring in this is the golfer’s clubhead speed.… Read more »
In addition to Tom’s more technical answer: As golfers learn the game and improve, their chances of making a great swing with great contact on occasion go up, so much you start noticing it when it happens. But this siren can be a temptress, making us think we can do that more often. (This is why they put more bunkers in the front of greens). It helps to remember that, as Bob Rotella reminded us, Golf is Not a Game of Perfect. But it is a game of “good.” David Owen, in his wonderfully anecdotal My Usual Game, tells the… Read more »
Ah, in simple terms, whatever model / style of clubhead, you’re hitting the CoP spot – the Center of Percussion . The ‘perfect’ impact of ball-to-clubface – it’s the size of a pinhead, the sharp end , All your swing mechanics presented the clubface to the ball – all the stars aligned in the universe ! Golf is mostly a game of accurate misses / mishits ……. o ___ so well done when it happens and hopefully there is enough fairway / green to catch them ! of course, the Wisho designs are impeccable too ! 😉
Tour PLayer
Center of Mass (CoM), aka center of gravity (CG), is more pertinent to impact performance from a clubhead. CoM is the intersection of all the possible balance points of the clubhead, and you are right, it is one tiny little pinpoint inside the head. Impact directly in line with the CoM will allow the head to remain the most stable through impact and maximize the energy transfer from the head to the ball.
TOM
Which often creates those most beautiful of misses: long. And causes you to think, “Why can’t I hit it like that all the time?”
Answer: Because it’s hard!
Hi Tom,
I’m going to order some SL EQ1 NX, just wondering about shaft recommendations. What is a good fit for the heads for someone coming from T100s with project x iO stiff? My 7 iron is about 165 with around 98-103 driver speed. I’m also curious what you think about the nunchuck iron shafts, I had them suggested. Thanks for any help!
JAMES You’ll always find me to be one who says if you are going to contemplate a change as significant as from incremental length irons to single length, why double up the change by changing the shafts? Especially when you say you have been playing a shaft that you seem to like and which seems from what you say to feel and perform well for your swing. So if you are just looking to “dip toes in the water” with a contemplated move to single length, I would say get a 6 iron and a PW and shaft them both… Read more »
Hello, I have the original sterling single length irons and I have also owned the original Cobras and Edel SLS-01 clubs. I like the original sterling’s since they are more forgiving than the Edel’s and less “clunky” feeling than the Cobras. However, I really like my 4 iron in both the cobra and edel irons. I would like to try the EQ1-NX heads. Can a 5 iron be bent up to 4 degrees to have a comparable 4 iron loft at 21 degrees. I’m swinging these clubs between 90-95mph at 37.5inches and have not had a problem getting the height,… Read more »
Nick I also would ask, wasn’t the original CObra and Edel 4 irons made to be longer than the rest of the single length irons, as a way to help give the golfer a few more MPH of clubhead speed with the low loft irons to help them get up and carry more than they would had it been made to the same length as the other single length irons? I can’t remember that for sure, but I sure seem to have a sense that was what Cobra at least did. Not sure about Edel. If the 4 iron was… Read more »
Hi Tom – Are you working on a new set of same-length clubs – thinking of buying the EQ1-NX but would wait if you’re coming out with a new model soon?
JAY If you had followed Wishon Golf over a period of time you would see that we are so totally unlike the big companies in several ways. One of the primary differences is that when I design a new model that passes muster to be added to the product line, it generally stays in the product line for quite a few years. For example, the 919THI driver has been in the line for over 12 yrs, the 771CSI irons for almost that long, and so forth. The reason is because in our business model, it is all about CUSTOM FITTING… Read more »
