I set my speed ring to approximately my REAL velocity (the factory info is generally inflated by 20 fps). Then sight in for a 20 yard zero using the crosshairs. The triangle above then becomes my 10 yard sero, first triangle down the 30 yard zero and so on.
In case you run out of adjustment on your scope turrets. If the bow is shooting high and you cant get it to adjust lower, puit a shim (I used a piece of alluminum pop can) under the FRONT ring. If it's shooting low, shim the BACK ring.
