Wyrównanie restu
Arrow rest alignment is the physical positioning of the rest in two axes — horizontal (center-shot) and vertical (rest height) — so the arrow sits on the correct plane relative to the bowstring and the riser centerline. Correct alignment is the joint actuator that makes nock height and center-shot adjustments translate into straight arrow flight.Szczegóły
The rest performs two positioning functions simultaneously. In the horizontal plane, it places the arrow's shaft on or near the riser's centerline — a setting called center-shot. In the vertical plane, it sets the height of the arrow relative to the nocking point, which determines nock travel angle. Because both axes work together, a rest that is correct in one axis but off in the other will undermine tuning adjustments made to the nocking point or the sight.
Center-shot is adjusted by moving the rest body laterally. A common starting reference for compound bows is to position the arrow shaft so it is just outside (toward the riser) of the bowstring centerline when viewed from behind — typically placing the center of the shaft roughly 13/16" from the riser's string groove on most risers. This is a starting point, not a final setting. Final center-shot is confirmed and refined through paper tuning or walk-back tuning. Recurve archers usually start with the arrow shaft aligned directly behind the string and adjust from there based on tuning results.
Vertical rest height positions the arrow nock at the correct height on the string. Most archers begin with the arrow sitting approximately level or with a very slight downward angle toward the point. The nocking point or d-loop is then set so the arrow is at a right angle (or very close to it) to the string at rest. These two reference points — rest height and nocking point — must be set together rather than independently, because moving one changes the effective angle of the other.
Rest alignment also has a third consideration on some rests: launcher blade or prong elevation, which affects contact geometry as the arrow leaves the rest. A blade that is angled upward too steeply can deflect the arrow vertically at the moment of launch. After setting horizontal and vertical position, always perform a clearance check — either with powder spray or high-speed video — to confirm that the fletching is clearing the rest without contact, which would randomize impact regardless of how well the rest is positioned.

Najczęstsze pytania
- What should I set first — rest height or nocking point?
- Set rest height first, then place the nocking point so the arrow sits square to the string at that height. The two measurements are interdependent, but rest height is the physical anchor; the nocking point is adjusted to match it. If you reverse the order you will often end up chasing the rest height after every nocking point change.
- My center-shot looks right visually but I have a persistent nock-left tear. Could the rest still be the problem?
- Yes. A visual center-shot check from behind the bow is a starting point, not a final verification — parallax and riser geometry can make a misaligned rest look correct. Move the rest a small amount toward or away from the riser, re-paper, and see whether the tear direction responds. If it does, the rest position was the issue.
- Does rest alignment change when I switch to a larger or smaller diameter arrow shaft?
- Yes. The shaft centerline is what rest alignment references — a thicker shaft sits the centerline farther from the rest launcher, effectively shifting center-shot. When you change shaft diameter, recheck both horizontal position and vertical rest height before tuning.
