Crossbow Scope Speed Setting Matcher
Multi-dot and BDC reticles only line up with your bolt’s flight if they are calibrated for its speed. Enter your crossbow’s speed to see which reviewed scopes are built for it.

Why speed matters for a scope
Each aiming mark on a BDC reticle is spaced for a particular drop at a particular speed. Too fast and the bolt hits high on the lower marks; too slow and it hits low. The bolt drop chart shows how much drop changes with speed.
Which speed to enter
Use a measured speed with your own bolts if you can; box ratings are best-case figures. Measured speeds for reviewed crossbows are on the test results page.

What if my speed is outside every range?
Choose a speed-adjustable scope whose range covers your speed, or a rangefinding or auto-ranging scope that calculates the aim point. A fixed reticle calibrated for a different speed will drift further off at each longer mark.
Can I use a scope made for a faster crossbow?
You can mount it, but the lower aiming marks will not match your drop. You would need to re-learn each mark’s real distance on the range, which defeats the purpose of a calibrated reticle.
Do speed-adjustable scopes need setting up?
Yes. You set the speed ring or dial to your crossbow’s speed, zero the top mark, then confirm each lower mark at its stated distance before relying on it.
