I have owned two of them. I had an original one in the early 90's. It was very heavy but as others said you could stay in it all day.
I sold it and bought a new one made out of aircraft aluminum. It was quite a bit lighter but you had to watch climbing with it because it wouldn't wedge as easy due to it's lighter weight. I still have it but I mainly hunt out of a ladder stand and a Summit Viper now.
I figure if I can't swoop down on the game,,I should not be in a tree hunting it...Stalking is my go to hunting style.Did use one in the swamps in Georgia,more concerned with snakes than falling or stalking.
