That's the only I bowhunt them. In one area I have 3 natural blinds I constructed to hunt out of. Not only do you want a good back drop, you need cover in front.
I also want a few trees in front so the bird can walk by or behind, giving the opportunity to draw on him. A simple trick is to set up facing away from the bird. Your back against a tree and in a small "V", run some netting or 3D leafy netting up maybe 3 ft high.
You want the bird to walk by you..and this is nerve racking...pass either side of the netting and wait for the quartering shot or hopefully, he displays giving you the back shot. I never use decoys...tried it with a friend 2 yrs ago and we setup wrong. Out of a blind, I believe they are very effective.
The buddy system...have the shooter 25-30 yds in front of the caller. If a tom hangs up...shooter still may get off a shot. Definitely use this method if using a decoy. Full face netting, gloves, total camouflage. Learn to call and know when to shut up.
