I have used one more than once not to locate birds, but to locate and relocate hunters. In PA there is one specific patch (Armenia Mountain for the locals) that gets hit hard every year, and I knew where there were a bunch of smart old toms roosted. I knew these toms wouldn't give up their position to locaters, so I decided to try it. There were cars all over the place in that area. I got about 1/4 mile away and let loose on the gobbler tube, and sure enough shortly after there was an army of textbook box call yelps working their way to me. I slipped out of there acrossed the Tioga river, worked around the hunters, crossed the river again, and got in to where I knew the birds were likely to fly down to and manged to kill a 17lb silent bird that morning. When I pulled the trigger I walked out by where the army of box callers where heading towards (where I originally was) and saw 4 of them all within a 200 yard circle.

With that said, I have about 400 acres this year that seems to be out of whack with gobbler/hen ratio and I am sure there will be some intense fighting between the gobblers because of this. There seems to be about 2-4 gobblers per hen this year. Since I will be the only one in there, I may use the gobbler tube a bit this year.
