After thinking about it recently, I told my wife I don't want one. I've bowhunted since 1977 and did just fine without it. The only advantage I could see using one might be to see the actual size of something and I admit it would be fun to have pics of the deer in my area. I absolutely see no advantage using one to help me set up for shots. Legwork lets me know where I want to hunt and besides..........we all know that during the hunting season deer can and will change their habits according to pressure and crop harvest schedules.
