What let-off really means, why compound lets you aim calmly far longer, and how it's clearly different from recurve and barebow.
"Why can I hold a 70-pound compound bow at full draw forever, but my arm starts shaking after three seconds with a 30-pound recurve?" The answer sits in two eccentric wheels at the tips of the limbs: the cams. They're the real difference between compound and the other bow types here — not looks, mechanics.
As you draw, the cams rotate out of their neutral position, and that changes the leverage throughout the pull. Just before full draw, the weight you actually hold drops fast — that's called let-off, given as a percentage, usually between 65 and 90 %. Draw a 70-pound bow with 80 % let-off and at your anchor point you're holding roughly 14 pounds — about the weight of a bowling ball, not a backpack full of bricks. At international competitions, that number is actually capped: World Archery allows a maximum of 65% let-off — enough relief, but technique still has to matter, not just the mechanics.
That's why compound archers can aim calmly for minutes where a recurve archer would already be shaking. No wonder compound is often the most technical — and in competition often the most precise — of the bow types. For comparison: recurve archers hold full draw weight until release, barebow archers shoot with no sight and full weight too. Compound is the discipline for anyone who wants technique and gear to do the maximum work for them.
A recurve bow stores energy only in bent limbs — linear, no trick. A compound bow uses eccentric cams to shape the draw curve: heavy at first, then let-off, then a hard wall at full draw. That wall gives you a mechanical reference point recurve doesn't have.
Recurve shoots with fingers and a sight, barebow with no sight at all, instinctively. Compound always shoots with a release aid and a sight — the mechanically most precise, but also the most technically complex of the three. If you want maximum consistency, you almost inevitably end up here.
Because holding at full draw is easy thanks to let-off, compound beginners can start with a higher peak draw weight than in recurve — men usually around 40–45 pounds, women around 30–40 pounds. You only feel the full weight briefly while drawing, not while aiming.
The peep sight is a small opening woven into the string that gives you a fixed line of sight. Together with the sight ring and level bubble, you build a chain of three reference points that has to be identical on every shot.
Unlike recurve, you can't just adjust the draw weight on a compound bow yourself. Cams, cables and string sit under enormous tension — adjustments belong on a bow press at the shop, not on your kitchen table.
The compound bow isn't an ancient invention: Holless Wilbur Allen filed the first patent in 1966, after sawing the limb tips off a classic recurve and bolting on wheels. What started as a hunter's garage project is today the most technically refined bow type there is — straight from the workbench into target sport.
The energy stored in cams and cables is real and shouldn't be underestimated. Never shoot without an arrow (dry fire) — there's a dedicated safety guide for that. Have safety-relevant adjustments made only by someone with a bow press, never improvised with garage tools.
When buying, ask specifically about the cam type, not just brand and color. A smooth single cam or hybrid cam forgives small release errors more than an aggressive binary cam with a short, hard wall — and that forgiveness is worth more early on than any extra fps. Also ask the shop to let you draw the bow to full draw without releasing — most dealers will let you try this under supervision, and that feel at anchor often matters more than the spec sheet.
Actually the opposite: coaching experience and comparisons show compound beginners usually reach good results faster, because sight, release and let-off cushion human error. Recurve demands clean body form from day one.
No. Bowhunting is banned in Germany, Austria and Switzerland — here, compound is shot exclusively as a target and 3D sport, even though the design originally comes from the US hunting market.
Barebow shoots with no sight and full draw weight until release — instinctive and raw. Compound is the exact opposite: maximum technical support through sight, release aid and let-off.
More than recurve, less than you'd think: a solid beginner compound with basic gear usually costs more than a recurve start, because cams, release and sight come on top of bow and arrows — but it saves you later upgrade costs.
