My biggies would be like you, the Carbon Clothing. Next or maybe even first would be all the artificial stinko lures they try to push and people buy. As far as the rangefinder. I don't think that's a useless fad. They DO work and not everyone can judge distances. It's a know fact. Some people cannot do it. I believe I saw somewhere that the average bowhunter in a treestandis off by something like 7 yards in range estimation at 30 yards. That's a miss folks.
