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,
I’m currently using a set of EQ1-NX irons. I prefer the feel of irons opposed to hybrids, Is there a way to get a 3 & 4 iron to match the same profile as the rest of the EQ1-NX irons?
RONALD No there is no 3 or 4 iron with the EQ1 single length irons because we learned from the first generation single length design I did that only a very, very small percentage of golfers have the clubhead speed to be able to elevate the shot with a 4 iron, let alone a 3 iron, high enough with enough spin to enable it to achieve a full club longer carry distance than the 5 iron. Keep in mind that the EQ1 single length irons are most typically made all to be an 8 iron length. That’s 2 full inches… Read more »
Ronald: I’ve played the EQ1-NX since its introduction, having played the previous version for 4 years before that. Back then, I swung the 8-iron 88mph. After being thoroughly satisfied with my set, I added the 4-iron. But I just couldn’t make it work for the reason Tom describes. Just not enough to gap it properly from the 5-iron. When I did move to the EQ1-NX, I went with 5-iron through SW. After becoming convinced the switch was a good move, I had a 4-hybrid built to the same specs. It, unlike the 4-iron, fits in beautifully. It plays just like… Read more »
Hi Tom,
I’m currently being fitted for a set of EQ1-NX irons, also looking to get the 4 hybrid and 3&5 fairway woods but I actually prefer the look of the latest 797hs hybrid & 927hs fairway woods. Is it possible to use these heads with the single length system?
Cheers
Allan
Depending on the weight of the shaft and grip, you could probably play the 797 #5 hybrid at 37″ and still be close to a normal swingweight, thanks to the multiple weight bores in the head. But to get to a 36.5″ length might be tough. Still, 37″ would be really close to the length of the single length irons, IF THE LENGTH OF THE IRONS IS A 36.5″ #8 iron length.
TOM
Tom. I play the single length EQ1s. Fantastic irons. Also have a 5 and 4 771 which are also excellent. Do you have any plans to put the HS300 face into the EQ1s? The HS300 seems to have a more crisp ball response.
Michael
Can’t do that because the HS300 high strength steel is no longer an option. The HS 300 is a totally custom alloy that has been formulated only for the one factory that I use to make the 771 irons. The steel mill decided after Covid that they need to have a much higher minimum order quantity to even make a run of it so that pretty much closed the door on us being able to use that anymore.
TOM
Tom: Not sure if you want to address this, but I am curious on your take from a technical standpoint. The one professional we know of who uses single-length irons–Bryson DeChambeau–recently saw his contract with his club manufacturer lapse. More recently, a major OEM to a set of their traditional (variable) length irons and made him a single-length set. Obvious challenges would be (a) the lie angles–especially since he chooses to build his clubs at a very upright angle, (b) the weight needed to be added to the low-loft iron heads (since they’re so much lighter to accommodate longer shafts),… Read more »
RICH I am well aware that Bryson is a free agent these days now that Cobra have said “good riddance” to him. I’ve not read or heard anything since that as to whether there are any named companies flirting with him or what, other than Taylor Made. At this point I am not too sure whether any of the majors would want to sign him because of several reasons – he would ask for a lot of money, he is known to be difficult to deal with equipment wise, he does for now still appear to want to play single… Read more »
The article I read was in Golf Magazine. Ping took a set of i230s and modified them. I’d have to think it resulted in a Frankenstein’s monster of a set. Yes, it was clearly a prototype for testing; he certainly hasn’t signed a deal with them. I’d have to think the other OEMs have intel on Cobra’s sales and that they’re “meh.” This, combined with dealing with that guy, plus the money he’d cost, tells me nothing will be coming along soon. The fact that he chose to retire from competitive golf–that’s how I see joining the LIV–just adds to… Read more »
RICH No question that the technical challenge of making a set of single length for Bryson from existing incremental length heads would be monumental. But PING has the smarts, the equipment and the people who could do that, I have no doubt. For the lie bending, it is possible to anneal the hosels, which is to heat them to a temperature that is high enough to soften the grain structure to allow for bending. Skilled clubmakers who also have the ability to polish/finish irons can do this to 431 or even 17-4 heads with a MAP gas hand held torch.… Read more »
Hi both,
Bryson has his own YouTube channel and posted a video a few days ago showing his clubs. They are indeed the ping heads with the LA Golf shafts he has before. He says he’s working with them, so I assume they’re doing the tuning.
Love the work Tom 🙂
Alistair
From the Bryson YTube channel. . . “. . . the little slot on the back of the hosel allows the club to move through rough easier. . . .. ”
HUH????? Uhhh, the boy needs some serious instruction in the facts of club performance!
TOM ;>)
To be clear, the notch is on the hosel and rather small. It simply could not have the effect Bryson is saying. Deep rough can catch the hosel and cause the club to twist. Really, really deep rough. But that little notch couldn’t have a bit of effect on that dynamic, even if it was designed for that purpose. But it’s not. As I understand it, not notch facilitates bending the hosel. When Ping made its bones with varying lie angles (hence, the colored dots), it did so with clubs cast from the very-hard 17-4 steel. Unless they had molds… Read more »
RICH
There have been several videos made by PING over the years that have shown their factory folks doing quick lie bends with a dead blow hammer, no bending machine. I have no doubt they have some folks who have done this so much over so many years that they will be tons faster than trying to use any type of LL bending machine to do that!
TOM
Hi Tom. I’ve seen a second hand 4 Fairway wood in very good condition, but in the 929 hs serie. I was initially looking for an EQ1-NX wood to complete my iron/hybrid serie. So is it possible to cut the shaft (S2S white 65gr) in order to get a 41″ length ? the actual length of this wood is 42.75″. Thanks a lot
Denis Yes, you could trim the grip end of the shaft in the 929 club to be 41″ and that part would be OK, but the main thing you would have to resolve is the swingweight. The assembled 929 has an established swingweight, done in the assembly of the club. After butt trimming 1.75″ the swingweight will drop about 10 points which is a lot and will most certainly make the club swing with a very light head feel after the length reduction. You will defintely have to increase the headweight to a point where when you swing the club… Read more »
Tom:
Would Denis have to be concerned about how the playing characteristics of the club might be altered with all that lead tape? I would think putting too much (and perhaps this isn’t too much) on the sole would lower the CG and cause the ball to fly with a higher launch angle?
RICH It takes a TON of lead tape to move the CG enough for there to be a very visible change in the launch angle, and by a ton I mean well over 20-30-40 grams of weight on the sole. That, combined with a higher than avg clubhead speed. If Denis has a clubhead speed under 100mph, adding 20g to the sole will barely change the visible height of the shot. This is one of those area for which I coined a phrase some years back – “it takes BIG changes in club specs to make SMALL changes in the… Read more »
Tom: I’ve been playing the EQ1-NX since its introduction, and the previous single-length model since IT’S introduction. I was playing on a course today without great fairway conditions. Not really spongy; just you and a little grass before you’re hitting that fine Arizona clay (ouch). Anyway, I noticed today that the bounce angle for the 5-iron through 9 iron was 5 degrees, lower than my old Ping I10, and much lower than the G425s I used to game. I have a pretty steep angle of descent and today I just couldn’t get good ball-turf-club interaction. But when I dropped a… Read more »
RICH Turf conditions with very little cushion tend to require irons with less bounce to help prevent somewhat of a ‘jarring’ feeling when you make contact with the ground. Mats tend to have some cushion to them, even the crappy mats. More than what you might find with really hard clay soil under sparse turf. Any more bounce such as what so many of the big company irons have would tend to be worse on the hard ground, I would think. I don’t have any real recommendation other than two things – 1) don’t play there anymore, 2) you can… Read more »
Tom: NO troubles at all. I was worried that the bounce might be too little, not too much. You’re right about playing courses with better turf conditions. I certainly have choices where I live, including a military course 3 miles away. Thanks!
Tom, I’m interested in purchasing a set of the single length irons and have a few questions. Can you achieve a D5 swing weight with a 36.5”length , 120g shaft and 50g grip? Do you recommend purchasing a shaft that is close to the final desired length, like a factory 8 iron shaft and then trim them all to the same length? What are your thoughts on wedge specific shafts for single length irons? I like the weight and feel of my KBS hi-rev 2.0 130g shafts but wasn’t sure if the kick points would materially impact the longer irons.… Read more »
Blake Depending on where the balance point is on the 120g raw weight shafts you would use, with the heads on spec at 275g, the shafts at 120g, the grips at 50g and the length right at a std 8-iron length of 36.5″, the starting swingweight with no weight added to any head would be right at D0. The hosel weight bore can accept up to a 9g tungsten weight which would put the swingweight at D4.5. TO get this higher, when the heads are ordered from Diamond Golf, you should ask them to hand pick the heads to get… Read more »
Hi Mr.Wishon,
Can you use the EQ1 irons and have different length shafts? Or does the iron only work @ single length?
Danny The whole reason single length even exists in irons is to offer the golfer the opportunity to have every iron be absolutely identical in every aspect – length, total weight, swingweight, balance point, MOI, lie – so that every club swings identical in every way to every other club. The concept is that if every iron swings identically, even with the same stance, posture, spine angle, swing plane, then you have a little better chance of achieving a little higher level of shot consistency. Deviating from that takes away from the identical club nature of a single length concept.… Read more »
The EQ1-NX is designed to be used with single-length shafts. But there are plenty of other Wishon designs that will accommodate your desire for a variable-length irons set. All of them, in fact.
Hi Mr Wishon,
Why didn’t you make the 585PC in single length?
Best regards
JK I did not make the 585PC forged irons for single length assembly because I aimed the model at golfers who are more of a low middle to low handicap player. Golfers who are in that category tend to be the last segment of golfers that would ever think about single length irons. Lower handicap players tend to cling to traditional aspects of golf clubs FAR, FAR more than golfers who are middle to higher handicappers. You can see a few lower handicap players using single length irons but it’s a pretty small percentage. And in truth, lower handicap players… Read more »
Thanks Tom for your reply.
I’m a single handicap and I love single lengths.
it would have been great to have the 585PC in single length, I will stay on the EQ1 NX.
JK
If single-length irons are going to be anything but a niche, players will have to grow up with them. High-handicappers won’t make the distinction and will continue their unsuccessful, off-the-shelf pursuit of the perfect iron. Low-handicappers will be so vested in the game they’ve developed that they would have no real reason to switch. Currently, it’s mid-handicappers (5-ish to 15-ish) with a sense of adventure who are likely to make the switch. (I made the switch about 7 years ago when the first Wishon single-length irons came out, then switched to the EQ1-NX when it became available. I don’t have… Read more »
how much better do you think the new EQ irons are compared to your old Wishon single length. They seem much better to me.
Hey Tom,
I’m looking to try something unique… 35 inch LW-7i, 36 inch 6i, 37 inch 5i, 38 inch 4i… between the EQ1s and the CLAs, is this doable?
Trent
The EQ1 irons can be built to the 36″ #6i, 37″ #5i but a 35″ LW would not be possible because you’d have to add more weight to the head to get it to normal swingweight than what the EQ1 LW head can accept. And there is no EQ1 #4 iron. In the 989CLA irons, you could build all these listed irons to the listed lengths you typed because of the additional weight bores on the back of each head.
TOM
Awesome! Would you see issues with having this kind of setup with the CLA irons?… essentially, if I have 35″ AW-7i CLA irons, do you see ball flight issues?
TRENT The whole reason I began putting more weight bores on several of my models was to allow custom building to a wider range of lengths, shaft weights, grip weights, swingweights. The only thing I would caution you on would be to be absolutely sure you are ok with short lengths such as the 35″ you state for the LW. With some people, getting shorter than 36″ on wedges can make them feel like they have to crouch more over the ball or that they really have to make an effort to stay down on the shot and maintain proper… Read more »
Hi Tom, Huge fan and currently gaming the Sterlings. I bought a set several years ago as a back up experiment as I like to tinker. I bounce between a +1 and 1 hdcp and finally at a place to put some more time in on my game in an attempt to pursue some mid am qualifiers. After much experimenting I have set up my Sterlings with 1/4” increments, SWs in the D-4 range, and basically tip trimming in half club increments to match the half of normal increment between the sets. 5i – 37.5 length 63.5 lie 6i –… Read more »
Colton Thanks so much for your interest! For the set with a little more of a player’s look, if you are planning that set to be single length or in 1/4″ increments like the Sterlings, depending on what shaft (weight) and grip (weight) you want to use, you should be able to do that with either the EQ1’s or any other iron in our design line. I assume since you are a very low hdcp player, you may be more inclined to be using a steel shaft, and possibly more like a normal weight steel shaft. If so, you could… Read more »
What will the swing weight come out to at standard specs?
36.5”length , 120g shaft and 50g grip.
If we use a graphite shaft that is the same weight as traditional steel shafts, such as a 110g or 125g parallel shaft, I would assume swing weights would match a comparably weighted steel shaft without the need for additional hosel weights. Correct?
TSG 36.5″ length + 120g raw weight shaft + 50g grip would be right around C9-D0 as the starting point, depending on the balance point of the shaft. You can never predict that all the clubs in the set would come out to this and potentially either require a little headweight addition or not because there will ALWAYS be +/- tolerances in the headweight, shaft weight, grip weight, as well as how accurately you cut each shaft for length. In EVERY assembly job, you can make a pre-build prediction but that can only be a rough guideline compared to the… Read more »
Thank you. Just needed a starting point. That is perfect.
Do you find these irons generally used by players needing more help, or are more solid ball strikers also migrating towards the single length iron concept?
In your vision, what type of player did you design these for?
Especially as they compare to the 585PC, which I am a huge fan of.
Thank you!
TSG Single length irons are and will likely be far more for players of say, 8-10 hdcp and higher and not so much of an appeal to very low handicap players. ANY player of ANY level could play the single length irons from a performance standpoint, but the very good players would tend to ignore them mainly because the vast majority of such players are very much traditionalists and not at all open to a concept as different or non traditional as single length irons. I designed the single length irons for any player, but mainly for those who have… Read more »
Hi Tom,
Apologies if this has been asked and answered but I couldn’t find a way to search the discussion on my phone. I’m 6’2” and a 37” club puts me in a position that is a little more crouched than what is a comfortable athletic position for me. That’s fine for partial swings but is difficult for free, full swings. It causes me to tend to stand up during the downswing. Your FAQ section says it’s ok to build to 38” but doesn’t seem to recommend it. Can you please clarify? Thanks for your time!
Darren The reason that building the EQ1 single length irons to a length of 38″ is not generally recommended is because of the effect that much longer length would have on the final swingweight/headweight feel of the irons. Every clubhead’s spec headweight is chosen on the basis of trying to achieve a normal range of swingweight that is not too light or too heavy, based on whatever length, shaft weight and grip weight the designer considers the majority of sets would be built with. The heavier the shaft, the longer the length and the lighter the grip, the higher the… Read more »

Hi Tom. I swing my standard variable 5i with confidence and accuracy. Its an older Titleist set with an older Adila graphite shaft, stiff for reference. Im not kidding, i wish i could play an entire round with that 5 iron. My question is this, can the EQ1-Nx be played with the same consistancy, a shaft just like it, but, the whole set built to the 38.5″ length? I truely think if my set was ALL my variable 5i length but loft changes throughout imight be hitting a potential home run here. I struggle with consicitancy with every other club,… Read more »
ROBERT No, it would not be possible to achieve anywhere near a normal swingweight (head weight feel) at a length for 38.5″ for all the irons. 37.5″ begins to be the upper length for that in the single length EQ’s, but if a very light graphite shaft is used, 38″ can be possible. But 38.5 starts to put that over the edge in terms of head weight feel being too head heavy for most golfers. What I recommend instead would be to take a measurement of your 5 iron’s moment of inertia. We’re not talking MOI of the HEAD, which… Read more »
Amazing Tom! I learn from you almost every day, thank you for your time. I will absorb all you said and go from there. Ive been stuck at about a 10/11 handicap for a decade, and i dont think the best Ping or Titleist will do it for me because of my constant toe/heel miss hits causing my bogeys. So i really want to see if the EQ1Nx is the change i need. Cheers!
Hi Tom. Have a question about graphite vs steel shafts used in the EQ1s. A variable length 8 iron is usually built longer using graphite compared to steel. I think this is for swing weighting? Are SL irons built longer as well? Or will the extra length affect performance and feel? Thanks
PAT The ONLY reason that you see the big companies sell their graphite shafted irons at a length that is longer than that of the steel shaft version of the same head model is because they are trying to use the same head model for both versions and they do not have a good way to add weight to the heads used to make the graphite shaft version. Heads on a graphite shaft need to weigh more to achieve the same swingweight because the graphite shaft is lighter than the steel shaft. The big companies rarely if ever make their… Read more »
Pat: Longtime user here. For decades I used steel in my irons. This included 4 years of using Tom’s first single-length irons. I had the same question when I switched to graphite shafts–do I get them longer because they’re lighter? No. My graphite irons are the same length as my steel-shafted irons. And yes, we added weight to the heads to get the swing weight right. (D-1.5) If you go longer, you’ll be less accurate, but you wouldn’t be the first person to have single-length irons longer than standard. Your choice, but it isn’t mandatory (as Tom says). And if… Read more »
Tom, a quick question, you state that the lower numbered clubs 5,6 etc have high COR and the rest have conventional COR. as I understand it COR is limited to 0.83. what is the conventional COR and is the high COR beyond the legal limit. just curious. thanks
Geoff The term “high COR” means the COR is close to the USGA/R&A limit of 0.830. It does not mean that the COR is above the limit. It also means the COR may not be right at the limit, but that it is higher than that of a conventional iron. Conventional irons that have a “normal” COR, such as forged carbon steel or investment cast stainless steel, are around 0.77-78. In general, the difference between an iron with a COR of 0.78 and 0.83 is about one full club in carry distance for the average golfer. The reason I did… Read more »

Hello Tom, I am a lefty currently playing sterlings and hope to go to the EQ’s shortly using my sterling shafts. My question. My wife wants to take up golf, as we are moving to Florida to a golf community. I want her to have the best experience possible starting out, and would like her to have a set of EQ1’s. I feel we going to have to make an educated guess on specs as she has no swing to observe and currently has some back issues. She is 5’2”, 100 lbs, 65 years old. Current thinking: Driver: 919THI 15.5… Read more »
Philip I really think I would drop all the lengths on the woods by an inch for your wife. At 5’2 and 100 lbs and 65, I just think the lengths you are proposing now will make the clubs swing a little too long in terms of control and comfort. For the irons, do this – get back to me with an accurate measurement of the distance from her left wrist to the floor (I assume she will play RH clubs. If she plays LH’d then do the measurement from the right wrist). Have her stand comfortably erect in front… Read more »

Hope all is well. Can you recommend some club fitters in Texas that I could go see about your single length? I live in the Corpus Christi area. Thanks fir the help.
JON Thank you very much for your interest. I am sorry but there are no independent custom clubfitters close to Corpus. The closest two would be in Mission, TX and up in Kerrville just a little north of San Antonio.

JIGGER Very glad to hear that the EQ1’s you got are behaving themselves for you and offering some more fun in the game!

No Wishon club designs are ever built “standard”, as are all the big company clubs. So with a big company’s clubs, it is easy to ask and know what the one stock shaft is that the… Read more »
Would the EQ1 NX have the same silky smooth forged feel of the 575MMC?
Kevin That is really impossible to answer because impact feel can be such an individual thing among golfers. What feels soft to one, doesn’t to another and what feels hard to one is the same way with other players. On paper, no, with the EQ being a hollow iron construction with a high strength steel thin face and the 575 being a solid, thick carbon steel, the two should not feel the same. But I can tell you that the slight hotness feel of the EQ from its HSS face can tend to feel “soft” to some players, which comes… Read more »
First off, let me just tell you my wife isn’t to happy with you Tom. Those 585PC irons look to good for me to not have a set. She, however, does not see the logic in that. Anyway, on to my question. I’m curious your thoughts on “gravity angle” in relevance to strike point. My wear pattern on my EQ1’s is developing slightly further out to the toe than it was on my gen 1 set. Maybe it’s just an optical illusion of a thicker top line and toe but I’ve always felt like the EQ1’s wanted to turn over… Read more »
JB I have slowly come to accept that an adjunct to my career as a club designer is to occasionally be in the middle of a situation between a genuine club appreciator/fanatic and a non golfer!! WHen you refer to your “gen 1” set with the more centered wear pattern, is that a set of the Sterlings? Just curious about that. In all honesty I have not heard the same observation as what you say about the wear pattern on the faces of the Eq irons you have. ANd in thinking about this, I am just not sure. I Know… Read more »
You are correct that my gen 1 reference is to the sterlings. Used that set for two and a half years before switching to the EQ’s. And nothing odd about the toe side hits when my path is in to out enough. A small draw shape and minimal if any distance loss. The higher MOI at work I’m assuming. The out to in toey ones are the bad pull hooks that derail a good round. If I wanted to experiment with lead tape on trying to keep a face from turning over, would you add it to the heel or… Read more »
JB In truth from the science of club performance, for there to be enough weight on the clubhead to have a definite effect on the rotation of the head through impact, that amount of weight would be so much that you would have a hard time even swinging the club with any sense of timing or rhythm or repeatability. This is one of the many myths that surround golf club performance. From a pure technical performance, adding a lot of weight to the TOE end of a head will increase the moment of inertia for the rotation of the head… Read more »
This season I gamed the Titleist T100S. They are really good irons. I did a MOI fitting with a club builder. He is a Wishon certified builder as well. I had been curious about one lenth irons for a while and I tested 5 and 9 iron in the EQ1-NX irons. I have never hit so good 5 irons like I did then.

Hey Tom,
Why are club makers switching from cavity back design to hollow body design? Particularly, why did you switch from cavity back to hollow body?
Trent It’s not just in the single length iron design that you are seeing more use of the hollow iron construction. Many game improvement irons and even some forged carbon steel iron designs are now being made in a hollow iron construction. The reason is because with hollow construction, you can more precisely locate a greater amount of mass in specific areas to more significantly increase MOI or more significantly move the center of gravity to achieve a different performance result. All that were reasons why I went from open cavity back to hollow construction on the EQ1 single length… Read more »
