Broadhead tuning is the final aerodynamic check on a compound bow. A field point hides launch errors that a fixed-blade broadhead amplifies — a bow can shoot clean tears at 6 ft and still fly broadheads four inches off at 40 yards. The fix is to shoot a group of field points and a group of broadheads at the same aim point, read the offset, and make small corrections to the rest, nock point, and (when needed) cam lean until the groups converge.
This interactive tool walks you through the diagnosis: pick the impact pattern that matches yours (broadheads left, right, high, low, or any diagonal combination) and it shows the specific adjustments — rest windage, rest height, nock point, cam lean / yoke, or arrow spine — that close the gap. Right- and left-handed conventions both supported.
