well yesterday with my hand climber I could not find a tree fat enough to climb, I have the XL straps and if a tree is too small the straps will only go inside the lower section so far so where I really wanted to be I couldn't go and had to go about 40yds from that run. with a hang on I could go anywhere!
also, what I don't like about the hand climber is the seat doesn't move out of the way (older version) and I wear pants with cargo pockets that are usually stuffed with things,,, so when I'm standing on the platform and go to turn around to say look behind the tree the dang seat gets in the way of the cargo pockets and kind of puts me off balance,,,,, I guess its all good just little things you eventually get used to.
with a hang on I guess you have to fumble with sticks,, not nearly as quiet as the climber.
I got used to the climber once someone showed me how to climb with one and now I love it,,, is it better than the hang on,,,,,,,,, yes and no which means now I want a hang on too!!
