I had a pretty good scare with my climber a few years back so I would say only go as high as you feel comfortable. Its a long ways down without any help around. Please use your safety harness. A gentleman in a different topic had a big scare this week. I recently purchased a ladder stand (2 seater with blind) and I will be using that from now on. Nice solid ladder and plenty of space. Its 15 feet to the shooting rail so I say that far should be sufficient.

Good Luck
