It depends a lot on what a Tom is doing. If he is gobbling a lot on the roost, I don't use a tree call if a bird is with in 200 yds of me. I wait until he is on the ground before I ever make a call. If he gobbles only once or twice I will make one soft tree call, just to let him know I'm there. I do tree call if I haven't heard a bird gobble and I use a flydown cackle. If a bird comes out in a field and looks, I give him some excited clucks and purrs, if he is over a 100 yds away. If he is closer I give him some excited cutts and a yelp or two then more cutts followed by some excited purrs. I'll keep some purrs going until he's with in range. If he doesn't seem interested or just comes out and wonders off I will gobble on a box call. This has worked very good for me this year, I've been out hunting 6 times and it has put a bird to the barrel 4 of the 6 times out.
