In all honesty, I have bought into a few of what I have to admit turned out to be a waste of my money. I do think a camouflage that matches the terrain-woods, etc is an asset when the hunting is going to be a closer ranges such as it is with archery and hunting turkeys. Some of the well made turkey and duck calls, when mastered help a lot. I have even had some good experience with a deer grunt call, but very, very few. Elk bugling and cow calls no doubt give the hunter an edge. Going heavy into scent control, cover scents, attractants scents, etc. .... ????... I have not yet bought into the need to go there. As far as this "electric field" idea. Hmmm ! I have had deer so close to me that on one occasion I poked a fat doe in the side with my rifle muzzle just to see what she'd do ... which was jump straight up and shift into high gear.
