RE: Tree stand Height?
Not a bad question. It all depends, what are the surroundings like, safty and your own comfort zone to name a few.
You want to be able to look over any items that may obtruct your view, and high enough that you don't look like somthing growing out of the tree or be sniffed out. Deer can smell even with up in the tree but I would argue that the higher you are the better chances of the deer no detecting you or your sent.
I personally like getting as high as I can, even if it means the tree rocking a little more than some people would like.
Last year in Ga. I was hunting in a climbing stand and it was "very" windy, so I decided to no go up so high and sure enough a nice buck came around and you would know it, the deer cought my sent with no warning and took out of there like a fright train. Now, I knew the buck would come back being this was his scraping area.
The next day though still windy I went ahead and took my stand as high as it could go and sure enough a few hours latter with the wind blowing in the same direction the same buck came through, never detected me and I got a nice six pointer.
Get up there and hunt.
KEEP HUNTING AND THE GREAT OUTDOORS ALIVE!
