I like getting as high as possible in a tree for several reasons. You can see a long way.. but this depends on the terrain of course. Your scent will carry over them if they are close. They wont notice your movements the higher you are.

If you are on the ground they might notice the slightest movement. I had a yearling see me in my stand and just stared at me. I was only 15 feet up. It did not think anything in a tree was a threat, so just sat down. Older deer get wise to hunters in trees, but the higher you go the less they will notice. Last year I was about 60 feet up and a buck comes along. I shot and missed him. He ran right under my tree and stopped.. then I got him. Never knew where I was.

When I am bow hunting I dont go as high because of the shooting angle.. otherwise I get as high as I can. I am using a climbing stand on public land.. and just carry it with me.

Keep in mind I used to be a tree surgeon.. so am comfortable with the heights.. and take plenty safety precautions.
