thanks for the info, I will also change my sights when elevated
NO!!!
If you change your sights for shooting from an elevated platform, then they will be off for shooting on the ground. You'll be a screwed goose if you get a shot opportunity while walking to or from your stand. Learn to shoot properly from an elevated position using your normal sights settings and you'll be way ahead of the game.
Go back and reread Kodiak Archer's response. He is spot on!
