Bow Centerline: Alignment, Center Shot & Tuning

The bow centerline is an imaginary vertical plane running through the center of both limbs and the grip, perpendicular to the bowstring. Archers treat it as a foundational reference for alignment, arrow placement, and tuning decisions on both recurve and compound bows.

Why the Bow Centerline Matters

Nearly every meaningful setup task traces back to the centerline. Using it consistently allows archers to align bow and arrow for repeatable aim, achieve reliable arrow placement from shot to shot, and establish a correct brace height for optimal draw length and arrow speed.

Center Shot and the Bow Centerline

Center shot refers to the arrow's lateral position relative to the bow centerline — specifically, how the plunger or arrow rest is adjusted so the arrow shaft tracks along that plane. These are related but distinct concepts: the bow has a fixed geometric centerline, while centre shot archery setup involves deliberately offsetting the arrow from perfect center to account for release mechanics.

For right-handed recurve archers, the arrow point should appear just to the left of the string when viewed from behind — typically 1/16" to 1/8" outside the string — compensating for finger-release flex. On compound bows, setting compound bow center shot commonly involves offsetting the rest 3/16" toward the riser on the arrow side to account for cam offset. Always consult your bow's manual for the manufacturer's recommended starting position.

Traditional Archery Alignment

In traditional archery, the bow hand is positioned so the bow centerline sits directly in front of the archer's face, with the bowstring aligned with the center of the chest. This body-to-bow alignment supports consistent arrow placement and reinforces sound aiming technique for recurve and traditional bows.

Verifying Center Shot: The Walk-Back Test

Once an initial centre shot is set, the walk-back test helps confirm it. Aim at a fixed point from close range, then step back and repeat. If arrows drift left or right as distance increases, adjust the rest laterally to bring the arrow back into alignment with the bow centerline. The pattern of drift tells you the direction of correction needed.

Paper tuning offers a complementary close-range check: a clean bullet hole through paper confirms good arrow flight, while tail-left or tail-right tears indicate the rest needs lateral adjustment relative to the centerline.
