Here's a good technique for practice: get yourself a CD player and tape player, or two tape players.Buy agood recording of live birds (I'd recommend Real Turkeys IV from Midwest Turkey Supply,
http://www.midwestturkeycall.com/
, there are others).Play a segmentfrom therecording and record yourself repeating thepassage. Listen to yourself on the recording trying to imitate the passage, it'll be some of the better feedbackyou canget. Youdo not need to beperfect or even "good" to make the diaphram work on turkeys, just concentrate on pitch and rhythm. Once you are "close enough" to the recordings (and your hide is thick enough )enter a calling contest or two - then you'll get the "impartial" judgement of your peers. Don't worry about placing [&:], thecalling contest route is only toforce discipline in your calling, and you'll learn to avoid "lazy" calling. Striving for perfection will help you over the long haul, add versatility to your calling technique, and may get youthat turkey that the average joe wouldn't get -- there are some turkeys that you can call in just banging two sticks together, there are others thatonly areal hencould bring in, you'll want to get good enough to get the gobs in the middle of these extremes...getting good with a diaphram can only help...
