i use a single dot tru glow scope and i set my arrow gun up at 20 yrds with the dial on 0. i am good at 0 to 20 yards at this setting. if i turn my compensator dial to 1 i hit my thirty, 2 i hit my forty and so on. i love this feature. i just know sometimes in the woods though when that big buck walks in at 32 yrds and i forget to compensate and shoot low, then i will hate the thing. lol

"i set my arrow gun up at 20 yrds"

No you didn't. You set a crossbow up.

dial-range gismo is pain and worry you should not have..
almost everytime i pull my bowstring back, it moves it to 2..

i have vari-zone scope not red dot,yet i like to use only 1 crosshair,the 20 yd one...
i am trying to like using the yard hairs ,not 1 and dial-range...

but it does move and could cost you a miss or bad hit with arrow.......
