Changing a setting that sits under cable tension usually means a press. You load the limbs, take the tension off the cables and the pockets, make the change, and let it back down. A press costs real money, and it takes up bench space you may not have. The shop has one and I still do not enjoy the loop.
That loop is the part that wears you down. The press job does not end at the press. You take the bow back to the line, shoot a paper tear, check speed, check the timing, and then walk back to the bench and change something else. Then back to the line. It is the walking that costs you, and it eats a customer's patience a lot faster than it eats your time.
That's why the new PSE bows caught my eye. Both are listed on the PSE website for 2027, the Supra X Trust 37 and the Supra X Trust 40, and the headline feature is something PSE calls the Limb Vise tuning system. PSE's own wording is that you can tune the bow "right on the shooting line without the need for a bow press." The technical page says the system uses EZ 220 shims for adjustment, and that a redesigned pivot interface keeps the limb and riser aligned at any limb bolt setting, and both models run a limb bolt with 7 turns.
Notice what that doesn't say. It doesn't say you need no tools. You still need the right shims and someone who knows which one to move. To be clear about the scope, because it matters. This is pocket and limb alignment work. PSE does not say it covers every tuning job on the bow. What Limb Vise appears to promise is that the small adjustments happen at the line with a few shims in your hand, instead of at a bench with a press. You make a change, shoot three arrows, make another change, and see what happened. If that holds up, something that used to cost a trip back to the bench could take a few minutes. For a shop, that's a big deal. A student's bow could go home the same afternoon it came in.
That matters more to me than a few feet per second. Speed is a number on a spec sheet. Getting a bow back in a kid's hands before the weekend is a real thing that changes how the week goes.
Now the part that gets oversold. Adjustable on the line does not mean you skip re-sighting, and it doesn't mean you skip paper tuning. A bow that's easy to change is still a bow that has to be checked after every change. PSE doesn't say anything about how much adjustment range the Limb Vise pocket gives, in any unit. It doesn't say whether the bow comes back to the same tune after being adjusted and shot, or how repeatable that is. It doesn't say how long a tune takes on the line compared to going to a press. It doesn't say whether the system shows up on other PSE models either.
Those are the questions that decide whether this is a real tool or just a good sentence on a product page. I can't answer any of them for PSE, and I haven't shot either bow, so I have no measurements of my own.
On the shooter side, PSE says product manager Gaius Carter shot the bow in his first competition with it, the 2026 World Field Championships, and came home with two golds and a silver, which PSE calls a record for medals won by a male compound archer at one World Field Championships. I looked at the results from that event. Mathias Fullerton beat Carter 72 to 71 in the individual compound final, so the silver lines up with the individual event. PSE doesn't say which events the golds came from. That's a good week for one shooter. That is not a spec, and I would rather treat it as a week than as proof.
As for which one to buy, I won't pick for you, because it depends on the archer. If you have a shorter draw, you're a junior, you shoot field or 3D, or you just want less weight in your hand, look at the 37. It runs 37 inches axle to axle and 4.5 pounds in the listed spec, and its FDSM cam covers 27.5 to 32 inches of draw. If you shoot indoor or fixed distance target, the 40 is the one on the list. It runs 40 inches axle to axle and 4.9 pounds, with 28 to 33.5 inches of draw on the FDSM cam. Both come in 40, 50, and 60 pound draw weights and share the same three cams. On the 40, EM2 covers 24 to 30 inches of draw and M2 covers 27.5 to 31.5. On the 37, EM2 covers 23 to 29 and M2 covers 26 to 30.
One warning before you get excited. If you're moving from a 30 inch hunting bow to a 40 inch target bow, your peep height will be wrong and the whole setup has to be redone. Same goes for the 37 if you're coming off something longer. Don't buy the axle length and assume the rest of your setup carries over.
Would I stock them? Not yet. PSE has not listed a price on either page, the pages read sold out, and neither bow shows up in the collection listings. I won't guess a price, and at whatever it lands at, this isn't volume for a shop like mine. There's no release date that I can point to, and the numbers that would tell you whether the tune repeats don't exist yet. I'd wait until a student asks for one by name, or until the first buyers have shot a full season and come back with their notes.
The idea is good. Moving the adjustment off the press and onto the line is the right direction for anybody who has ever walked back and forth between the bench and the target. How well that holds up is a question for the first full season, not for the product page.
