Go to a backpacking store, and buy a roll up chair like this

Getting one of these chairs is best thing I've done for my turkey hunting in years. Due to old age and injuries, I have a very hard time sitting for more than 10 or 15 minutes without back support, but with one of these chairs I can sit still for hours comfortably. They are historically correct, and in fact seem to have been invented by Daniel Boone specifically for turkey hunting. This year, I'm going to take my shooting sticks with me into the turkey woods. I think that will be an improvement as well.
Turkeys vary, as do hunting situations. I hunt turkeys in the west, usually in Ponderosa Pine forest. These forests can be very open, and many times I have had to call turkeys with my back up against a big pine, with nothing in front to hide me. I have called turkeys within a few feet of me doing this, but much more commonly they will hang up at 50 or 75 yards. They may not understand exactly what you are, but they get suspicious, and refuse to come in. I think most of my turkeys have been shot between 25 and 35 yards. The furthest I’ve ever shot one was right at 40 yards. I’ve never bothered to put together an outfit that was capable of killing turkeys at 50 yards, but I have friends who do kill birds at that range.
