@azreal289 We use scopes on all targets and no altimeters or anything fancy. We know our sight settings prior to the match and adjust the scope elevations for each of the 4 different distances when we get there. We judge the wind by guestamation and adjust the windage as we think is required on...
@dirtyminded604 Blinders, they are inexpensive. You could probably make one yourself with some rigid foam (mousepad?) - To buy one --- see Champion Shooters Supply
