I'm quite interested in this also. I've only been turkey hunting 5 times all by myself and have only learned what I kno from shows and experience. My first hunt I set up 40yds from tge roost and didn't have any decoys. I called, not aggressively at all, 35 mins later he came and bam dead. The next few times I used a hen feeding and Jake decoy. Called in three different toms two of which came in 50yds, this is separate occasions, spotted my decoys and hung up only to leave. Tge next guy circled me came in quiet and I was unprepared. Last hunt I was on I took no decoys. While turkeys seem to always be able to pinpoint exactly where you call from they seem more interested in finding out what's going on when they see nothing. This Tom came off the roost entered the field 200 yds away Strutted alot always working towards me and bam 51yds dead bird.
