I used to think that height really made a difference untill last year. I was begining my asscend in my climber when I heard something walking down the access road I was on. so I stoped climbing pulled my bow up and knocked an arrow when here come two of the biggest bodied deer I have seen in a long time. 1 was a spike and the other was a 7 pointer. Being only 7-8 feet in the tree I thought for sureI was busted. Nope ended up taking the smaller racked 7 pointer. Dressed out at 215lbs. The spike walked right by me and looked right at me and kept walking, and the 7 pointer went to the corn, looked at me several times, stepped behind a big oak, I drew, waited, he stepped out and WACK!!!!! ran about 25-30 yards and dropped. SoI really dont think that height makes that much of a difference. It does help conceal you and carries your scent away from youfurther, but as long as you can make the deer not feel threatend I think theyd walk by you at 2 feet.
