i was wondering what i should set the first cross hair at 20 yards cause theres five crosshairs and after u set the first one the others follow upat 10 yards

i have a Horton Legend Sl and have my first crosshair set at 25yrds. It is good at 30... 35.... 40... and at 55yrds a full bodied deer target looking threw scope fits between the first 2 crosshairs and is dead center. Just depends on how fast your bow is and all wieght of broadheads and arrows. but I wouldn't trust the 10yrd every crosshair if i were you.

Many of the scopes I have installed for crossbows regularly indicate that after you sight in the top crosshairs for either 20 or 25 yards then subsequent lower crosshairs may be on a variety of yardages within a given range. For example, the second crosshair may be dead on at 27-33 yards and not exactly 30...and so on and so forth.

Just for argument's sake though, yes, I would guess that the subsequent lower crosshairs should be about 10yards apart and, yes, you should start at 20.
