I would say by practicing/using it. BUT...I borrowed an Old Man climber a few yrs ago, and everytime I thought I was up pretty good, I would turn around, get seated, and lo and behold I was only about 10-12 ft up!! My fear of heights gets worse as I get older. I never did use it for hunting. I prefer to use a box blind or tripod, or even a good ground blind. I wish I could, because I think they allow you to really get in there where the deer are.
