Ive owned several different climbers. I have 2 summit vipers of different vintages(both have front bar), an Steel collapsable rivers edge climber, and an API bowhunter climber, my cousin has has had the same as me but his API was the grand slam (one with the front bar). I have a couple of homemade platforms for hangons and have one set of stor bought sticks and one homemade.
By far the quietest and easiest to transport, setup and adjust was the summit viper. It takes a little work to get the system down and a couple of extra cince straps and some pipeinsulation over the front bar to quiet things down and make more comfortable but by far the best.
Climbers are great on public land or on other areas where you dont want your stand getting stolen. I have a couple of areas that i take my climber in the off season and find trees and trim lanes. "Finding the right tree" is the down side to climbers because you have to hunt for a tree. U either have to hunt for the right tree and/or go pre/post season and do some trimming... I like ot do mine post season, you can see more on the west side (im a bow hunter).
I use my ladder stands on private property in areas that shouldnt get any other hunters. they are WAY easier/quieter to sneak into in the morning than any climber. They are hard and dangerious to set up IMO, and you dont have to trim as many branches or hunt for the right tree as much.
Finding the right method to pack your climber and your daypack is the key to liking hunting from them. the summit viper is comphy and easy to sit for long periods in. Ive piced up mine for $150 used and there was one on here recently for that price... some people dont like them (tree stands) i think its because they havnt quite figured it out how to hunt from them.
All the other climbers were noisy, and or harder to adjust than the summit. I actually thought the chain on the API would be easier to use, but it was much harder to adjust in the tree than my Viper. I left my API in Kansas with my buddy for the next time i head down that way hunting. The cheek $70 steel rivers edge was noisy as hell packing and sitting. I have used it when i founda spot that i wanted to sit in the morning and just left it attached to the tree and wasnt worried about it getting leggs. it never did.
