Depends on the cover, the tree I am in and the terrain. I have one tree I hunt often and it's amongst a whole bunch of cedars. I'm up maybe 10 feet max, but I am totally concealed. I really can't go much higher in that tree and it's proven successful year after year. On avg, I get 2-3 deer per season out of that tree.

In other areas, I go up maybe 20 feet max.
