STERLING
SINGLE LENGTH IRONS
A Unique Set Design to be Built to One Length for all Clubs to Deliver a Perfect Match of all Elements of Swing Feel for shot consistency.
Features:
-
- Single length construction ensures all possible elements of swing feel are identical for each club in the set – same MOI, same total weight, same headweight, same balance point – to offer the chance for improved shot consistency
- Identical length and lie allow the golfer to use the same stance, same posture, same swing plane forimproved shot consistency
- Optional high COR #5 hybrid with high COR #4, 5, 6, and 7 irons offer proper distance for the low loft clubs at the shorter single length. Other single length sets may lose distance with the low loft clubs
- Conventional cast carbon steel in the #8 to gap wedge with 5* loft increments blend with the high COR design of the low loft clubheads to offer proper distance gaps and proper
distance with the high loft clubs. Other single length sets may generate too much distance with the high loft clubs - Available in a #5 hybrid or #5 iron to match the player’s desire and ability, with #6 to 9, PW and Gap Wedge and Sand Wedge
- Sterling Irons® Single Length clubs can be built to 36.5”, 36.75 or 37” length for each club as fit by the Clubmaker for the golfer’s comfort and preference. Contrasts with most other single length sets being created for a 37.5” length – which can generate too much distance with the high loft irons
- Intended to be custom fit with any Wishon Golf S2S iron shaft model and flex to meet the swing speed, transition/tempo and release point of the golfer.
- Sterling Irons® hybrid uses standard iron shaft (.370)
- The #4 iron should only be used by golfers with a #5 iron clubhead speed of 85mph or higher to be able to make the club generate the proper trajectory and height to be able to carry the ball further than the #5 iron
- Available in RH (#5 Hybrid, 4-9, PW, GW, SW) & LH (5-SW); New Blade Wedges (LW, SW) available in RH only

Still loving the EQ1-NXs. The other day I had a personal-best 15 greens in regulation on a difficult course, including a 4 hybrid shot where I had to work a little draw around a tree to a raised green.Brilliant design, Tom.
Mitch
Draw around a tree to a perched green with the #4h is saying a lot about how well you are playing with the new sticks! It’s great to hear and is music for this designer’s ears!!
TOM
I’ve had the Sterling Irons for 3 years. Now the PW just started making a weird vibration when I hit it. What would cause that ?
Paul The only two possibles it could be would be 1) almost every iron ever built has some final weight put in the head to bring it up to the final desired swingweight balance for the player. The weight plug that would be in the weight bore directly under the tip of the shaft could have worked its way loose and could be rattling in its weight bore. The fix would be to have the shaft removed, check and re epoxy the weight and re install the shaft. 2) Possible but not likely that the shaft could be coming loose.… Read more »
Graphite shafts sometimes crack or delaminate, especially near the tip where there is a lot of stress. If that happens the shaft must be replaced
More on the hybrid situation – removing the back weights and putting the 10g tungsten in the toe port fixed the problem. No more toe hooks!
Hello Tom, I am in the process of buying a set of the EQ1 and trying to decide between shafts. I am looking at the S2S White S, the Black S, or the Black R and was hoping you can provide some insight. Also, if there is another option I am overlooking, please advise. I “fit” into the Black S, but I prefer a high ball flight since I can readily knock down my wedges, but can’t as readily hit my 6 or 5 irons higher. Also, I play a lot of 3/4 shots which drops my ss down into… Read more »
RC Based on what you say about being able to control shot height in the wedges but wanting to have a little more help with trajectory in the lower loft irons, I would lean toward the White shaft design over the Black. While the White has been thought of mainly as a shaft for average skills/technique golfers with a midway release, the tip section is most definitely not too flexible at all. In fact even though I still have a fairly late release in my own swing, I converted to the Whites several years ago and have never sensed that… Read more »
Thank you for the response. I will start with that.
I’m really enjoying the EQ1-NX irons. Yesterday I started testing the hybrids. My irons go to 5I so as a starting point I built a 4 hybrid at 1″ longer than the 5I, same R-flex S2S White shaft as the irons, with two of the 5g tungsten weights in the rear ports. There was a ripping headwind in the practice area that accentuates any spin. I was getting gear-effect toe hooks like no tomorrow. I changed my setup to hit more toward the heel and the sidespin settled down – but I don’t think I can play this setup in… Read more »
I have a set of sterling one length in 5-SW. I’m a lefty. Could I buy a SW at 56 degrees and bend it to 60 degrees to play as a lob…I see it says plus or minus 4 degree bend, and since their is no lob wedge option in lefty trying to keep my set consistent…i know more goes into one length than just bending the club, but thinking outside the box is what one length is all about.
KING
You can use a left hand SW and bend the loft +5* to be 60* loft. But do please understand when this is done, the sole bounce angle will automatically increase by 5*. This might be OK for use in softer sand but if you play the club from firm, short mown turf or from firm sand, the increase in bounce on the sole could very well cause some problems in the form of the clubhead actually bouncing into the ball and causing a bladed shot.
TOM
I have been using EQ1-NX for about a week now, after having used Sterlings daily since they first came out. Here are my impressions so far. The EQ1-NX heads do indeed look a bit larger than Sterlings. The look inspires confidence, especially after you discover the following performance characteristics… The EQ1s are definitely more forgiving in several ways Off-center hits toward the toe and heel go straighter Thin strikes low on the face fly higher The sole interacts better with the turf; it’s less prone to “grab” in gnarly grass I really like the EQ1’s versatility for chipping. The clubface… Read more »
I concur with these observations fully.
Tom – been playing Sterlings for 3 years and love them. The Sterling heads are larger (more surface area) than average and I really like that feature.
Three questions
1. How large are the heads and how do they compare to more mainstream brands ?
2. How do they compare to the EQ heads?
3. What is the trade off of a larger head. Seems like more mass is easier to hit, particularly for off center hits
Thx
PAT: If you are asking how large are the Sterling iron heads compared to other companies’ iron head models, I am very sorry but I can’t answer that very well because I just never look at other companies’ club designs so I don’t have a frame of reference there. If you are asking how large the Sterling iron heads are compared to the new EQ1-NX iron heads, I can tell you the EQ1’s are a little tiny bit larger overall but not by more than a little bit. Otherwise you start getting the head size to a point that some… Read more »
More EQ1-NX results: I am testing EQ1-NX a few clubs at a time, trying different shafts and different shot types and turf conditions. I started with the SW built with a standard weight steel shaft (Wishon Smooth Steel) because I like extra weight in the high loft wedges that are used mostly with partial swings. Then I branched out to 8 iron, trying both a graphite shaft (Wishon S2S white R flex) and a lightweight steel shaft (Wishon SuperLite R flex). I prefer the graphite because I get a slightly higher ball flight and the dispersion seems to be a… Read more »
Tom,
Are the EQ1-NXs suitable for everyone? I’d guess that there is some minimum swing speed/strength/etc requirement. The reason I asked is that the comments have all slanted toward men of various ages. Not to be sexist but it made me wonder about women of all ages and whether they would be candidates for the EQ1-NXs?
ED Yes the EQ1-NX irons can be played by any golfer regardless of gender or handicap or ability. A big reason that I decided to reduce the offset on the EQ1 vs what I had done on the first generation single length irons was in fact to allow them to appeal a little more to a better player. Better players typically do not choose or like iron designs in which there is more than a very small amount of offset so with our first generation single length model I noted that a fair number of better players that were interested… Read more »
I really like what Tom has done with the new EQ1-NX sand wedge. The sole profile is very effective from a variety of difficult lies. That, in combination with the weight distribution and the face design, makes the ball come off with a predictable trajectory under conditions that used to cause me trouble.
What are the factors involved with choosing either a graphite of steel shaft for single length irons? Is it personal preference or does one favor a certain type of player? Thanks
LARRY There are a number of factors that a golfer must look at to determine a choice between graphite and steel for the irons. And the decision points are the same regardless if you are talking a single length set or a conventional incremental lengths set of irons. 1) WEIGHT – while there are steel shafts out there as light as 75-85 grams, if the golfer really needs or wants to have a lighter total weight in the irons, the choice will be a lighter weight graphite shaft. Graphite iron shafts can be found as heavy as the heavier steel… Read more »
UPS just delivered a set of EQ1-NX components. Time to build test clubs! Can’t wait to try them out!
What’s the swing weight of the s2s stiff shaft in the one length ?
Jason Thanks for your interest. There are several different specific S2S graphite shaft models, each one designed with weight and stiffness characteristics for different golfer swing types – S2S White, Red, Black, Green, Blue. You need to let me know which one you are referring to in your question. Also, to be sure, in your question are you asking what would be the starting swingweight for the shaft you wish to know about with no weight added to heads that are made to normal head weight? I am glad to help but need more specifics from you to do that.… Read more »
Hi Tom – hope you’re well and staying safe Wonder if you could help… I’m keen to pick up a set of Sterling single length irons and was looking at 5h-SW based on some previous advice. As you can imagine I’m looking to fine tune the set as far as is reasonable but COVID-19 obviously creates challenges. My stats are Age 51 Height 179cm Wrist crease to finger 18.5cm finger length 8.25cm Wrist to Floor – 91.5 – 92cm 7 iron carry 140 -145yds Strength slightly above average Medium tempo with slight aggression I play with a 3/4 swing (Don… Read more »
JIM Many thanks for taking the time to stop by to ask questions about the fit of the Sterling irons. Obviously as long as your fitter has good experience, being able to work with you in person to see and evaluate your swing motions and to obtain your feedback will be far better than what I can do from afar. Based on your measurements all being correct, your length would be 36.5″ (normal 8 iron length) and the indication is you would need an upright lie angle. However your clubfitter will likely do a dynamic lie test which will be… Read more »
Thanks Tom – much appreciated. My fitter Iain has already started the process and I’ve tested two irons this week…by coincidence the swing weight is the one thing I’m trying to fine tune so many thanks for you input
Best regards
Jim
Hi again Tom I’ve recently taken delivery of my irons and the results are very favourable…I’ve still to pick up my 5h but the 6 iron is sublime. Moreover, my concerns about short iron lengths is also proving to be unfounded as a result of the consistency on offer. I digress… Now that I have the irons, the next point is to look at the hybrids;-now that I have dialled in my specification for the 1st gen Sterling irons is there an obvious and consistent lead into the EQ-1 hybrids ? My hunch is that I’d like to continue as… Read more »
jim Thanks very much for the input on the new irons. WE’re pleased to head the results are good so far! I assume the 5 hybrid is going to be the same length as the rest of the single length irons so my advice would be that once you get the 5 hybrid take a good long look at what the distance gap is between it and your highest loft wood that you carry. Also take a good look at the distance gap between the 5h and the 6 iron to be sure that gap is not too much nor… Read more »
Hi Tom, i currently play 4 to LW SSL irons V1 with S2S white stiff shafts length 37″. I also use 919 HL driver which i beleive is 13 degrees. Now the new EQ1-NX are available i was thinking of replacing my hybrids and possibly my 4/5/6 irons with a combination of the new woods and hybrids all at single length. My questions are: 1) Would i need to make the wood and hybrid head weights 274g the same as the V1 irons? 2) Can I use the same shaft length in the woods and hybrids as my V1 irons… Read more »
ROB Very important – the new EQ1 woods are not designed to be built to the same length as the hybrids or the irons. You can’t do that and expect to get close to the normal fwy wood distance so the woods have to be their own separate single length vs the hybrids and irons. But the hybrids can be made to be the same length as the irons because the hybrids have the capability to be able to get the head weight up to the same level as the irons with multiple internal weight bores in the heads. So… Read more »
Hi Tom, Thanks so much for your reply. I’m so glad i asked now. I am surprised by the loft gap between last hybrid and first iron. Thats wider than i would have chosen. I would have tried to keep it more consistant between all clubs i.e. 4 degrees. The combo’s above of 2 woods, 1 hybrid then irons is great, but is it possible to use more hybrids? Or would that cut out too many irons? i.e. 4h, 5h and 6h would the first iron be 8 iron? I am loving the SSL irons and playing so consistantly with… Read more »
ROB If a golfer has a normal to below normal clubhead speed, it is very common to see a head with a lower and more rear center of gravity location generate more carry distance than an iron that has the same loft or a loft that is +1, 2, 3 degrees higher. This is because the lower and more rear CG location jumps the ball higher in launch angle. When the ball speed then kicks in the ball can keep flying up and up on that higher launch angle to achieve better carry distance. That’s why in many sets the… Read more »
what is the blade length? thanks
WIlliam Wish I could post diagrams to make this easier to follow but that’s not possible so words will have to do. Blade length is the length of the clubhead from the end of the outer edge of the toe end of the iron head to the bottom of the hosel as measured along the ground. When you look down on an iron in the playing position, the blade length is how long the head looks to you from heel to toe. Very short blade length compact size irons will have a blade length in the area of 75-76mm while… Read more »
I bought a set of these in May ’20 and have now played 4 rounds with them. I play off a 15 handicap and ball striking consistency has always been an issue for me. These clubs take out the need to consider ball position and distance from ball for each club and therefore have already greatly helped me. As for chipping/pitching into and around the greens, these have come into their own and given me greater confidence and consistency. These are a fantastic set of clubs and I absolutely and thoroughly recommend these clubs to anyone that may be looking… Read more »

Wow, how great is that to be able to hear how much you like the new irons and how much more they are helping you to enjoy this great game a little more. Being able to hear this is without question the best reward I can have in my “work” which as you can tell from the quote marks has never really been work!! Thanks much and the very best to you for many more shots and rounds that bring a smile to your face!
TOM
I believed that the irons are very good. But they are still not yet in europe. I’m waiting, waiting, waiting, etc…
no news up here about the eq1-nx.
JM
Diamond Golf has received the first production shipment of the EQ1-NX irons and has been filling the pre orders for the past week. As far as I know they have been filling those orders in the order they were placed to be fair. I do not know precisely whether there were more initial orders than what the first shipment covered. If so, then any orders not yet shipped as well as any new orders for the irons would have to wait until shipment #2 arrived which should be in a few weeks.
TOM
Bottom bore to ground is 1/4-inch lower on the Sterling 5-Hybrid than on thre remainder of the irons.
Tom, I notice that there is a new single length iron set from Wishon Golf. The EQ1-NX. I am a senior golfer with a handicap of 12. M 7 iron goes 140 yds. Which of the two sets do you believe is more applicable for me? I need to get my irons higher in their trajectory.
JOHN Thank you very much for your contact and your interest in what we are doing. We appreciate that very much. I need to tell you that if your interest is more immediate, due to continued workforce reductions at the production factories, the first deliveries of the new EQ1-NX clubheads has been delayed another month to mid July. We’re sorry but the factories have never recovered the workers that stayed home when lockdowns went into place in February. So if you were planning to look seriously at a new set before August, the Sterling irons may be the better choice.… Read more »
Hello Tom!!
A couple weeks back, I had Terry at T’s Golf in Hazel Green Alabama build me a set of Sterlings. We used a SK Fiber Tri-Tec regular shaft with Lamkin Sonar Std+ grips. I have to say that these irons are game changers. I have made a drastic improvement in my consistency. But, I now see an issue with my club selection in the future. Do I play these or my 771’s with SK Fiber Pure Energy shafts??? I will admit, this is a great problem to have!!
TIM
Given all the problems that can beset people, you certainly do have a very good problem!! That’s very nice for me to have the chance to hear that and thanks so much for taking the time to not only let us know of your “problem”, but first and foremost to have chosen to work with Terry for your fitting needs. He’s very good and I am pleased that he chooses to fit golfers with my designs.
Thanks much and the very best to you in this great game,
TOM
hi tom – was hoping for a bit of insight between 2 shafts – the ns modus3 120 and the ns pro 970 (titleist). i think these are similar, but have no data on them and was hoping you might be able to tell me. i like the 120’s but think they’re a bit much for me in an s flex, and while i thought about moving down to an r flex, i saw the ns pro 970 and thought about staying in a s flex with them. my thinking is that the ns pro 970 has a bit more… Read more »
TOM I have bend profile measurements on the Modus 3 120-s but I have no information on the 970, mainly because if this is a proprietary Nippon shaft for Titleist only, the policy has always been the shaft maker can’t provide anyone with any testing samples of an OEM shaft and of course the OEM for which it is made is never going to make any of their shafts available for testing or measurement. I can tell you from the data I have that the 120-S is not very butt stiff but it is reasonably tip stiff. Not as tip… Read more »
hello Tom. I am 63 years old and I started golf for about 4 months. After a lot of research into single-length clubs, I decided to take the plunge and equip myself after a ckeck-up with André Thaon. I am very excited to play with your irons. Sorry for my bad English.
Regards Regis
REGIS Thank you very much for taking the time to visit our website and send us your comment message! We appreciate that very much! I can guarantee you that the very, very best decision you have made is to work with Andre for your fitting needs. Andre is without question one of the very best clubfitters in the world and I am NOT making that up just to tell you that. Andre is as good as a clubfitter can be. Period. So you will for sure end up with the best set you have ever played because Andre will take… Read more »

Great review of the Sterling’s. I know it’s a little late but I think this endorses the concept and hopefully will see even more people try the new EQ1- NX.
I’ve played the Sterling’s since they first arrived and think they’re the most consistent irons I’ve ever hit.
I hope you are doing well and staying away from the virus. I have ordered the Eq-1 iron heads, 2 of the hybrids, and the 3-wood. I have also ordered the Nippon 950 GH Neo shafts for the irons. Since it appears the shafts will be in this week, and the EQ-1 will not arrive until June, I have thought about reshafting the current set with the new shafts to try them out. Is the hosel depth the same for the new irons so that I can just extract the shafts from the old heads and install them in the… Read more »
David No problems here with the stay in place as ever since Diamond Golf took over the brand and I became a solo consultant, I was never around any people during my days anyway and no one ever walked into my workshop/office. So for me and my daily routine, nothing much has changed other than the sadness of reading how much this is and has really affected and damaged the lives of millions upon millions around the world, which is a terrible tragedy. I think about that every day and hope that wisdom will prevail to get us all out… Read more »
