I thought rangefinders were against the comp rules anyway?
My concern is the ranges of targets on the zero range. If I go to another club and check my zero before the comp, I would like to be able to laser the zero targets to make sure they are at the ranges they claim to be. Otherwise I might be "unzeroing" my gun!
