Deer will notice something different or new on the ground like a blind and will take a while getting use to it or comfortable being around it but a blind like that up in a stand shouldn't take any time at all for a deer to be comfortable around....its more natural and if they happen to look up at you it would be a lot more difficult for them to see you or pick up any movement!Just be sure that the camo doesn't block you from making a shot or interfere with the limbs or quiver on your Bow?

When I Rifle Deer Hunt out of my ladder stand I drape 2 seperate pieces of camo material on the right and left side of my fold down arm rest on my stand to hide me in case a deer wouldsee me move any in my stand.
