Once the deer starts heading your way are you going to contiusly check his distance...30, 25, 20,19,18,17,16. Then put the range finder down and draw your bow. To me that's a set up to fail.
I agree, that would be a bad idea. But I think most of us that use rangefinders use them to establish a perimeter around our stands. When I get into my stand I range out trees and make mental notes of their distances. If a deer comes around that tree I know the approx. distance +/- a couple yards.
