Target vane for field points: matching the vane to the head

When to fit a 1.5 to 2 inch target vane, what it steers, and the trade-off against the other size.

Dry-fire warning

Crossbow bolt data and archery arrow spine, nock and thread data are quoted from each manufacturer's published figures, owner documentation and industry standards, cited on every page. A nock, spine or grain-weight mismatch can cause a dry-fire that damages the bow and can injure the shooter. Confirm against your own owner's manual and the arrow maker's own chart before shooting, and never drop below the stated minimum total weight.

Vane fitmentmanufacturer data, cited
Vane length1.5 to 2 in
Best forField points and low-profile target and 3D arrows
Fitment ruleA field point does not fight the vanes, so a short low-profile 1.5 to 2 inch vane gives enough spin with the least drag, which flattens trajectory at distance.
Trade-offA short vane steers a fixed-blade broadhead poorly, so it is a target and field-point choice; move up to a 2 to 3 inch vane to shoot fixed heads on the same shaft.
