as a beginner myself (this will be my second full season) calling was one of those areas that perplexed me and at times frustrated me (next to trying to locate the buggers, lol, but that's another topic), that is until the fellas here helped me get my head screwed on straight. Starting out simple is better and less is more when it comes to calling, at least until you have a better sense of what the birds react to and can take their temp, (get a sense of their mood on a given day). Here is what not to do because I did it or tried it and failed miserably, lol! For starters unless your naturally gifted forget about the mouthcalls, at least for your first season...you can practice with them if ya like, but I would leave them at home until your better and sound more realistic. Get your self a push-pin box and a slate/glass pot n peg. The push pin is fool proof and with little practice you will generate great sounds with little movement and that's key. I also like the pot n peg for the same reason, easy to make great sounds with little practice and movement. Some will say the same about a box call, but I've found I tend to use more hand movement with a box call and can make a greater variety of sounds with a pot n peg.
Speaking of variety of sounds...don't try try to imitate every sound that's out there. Keep it simple and there are really only 3 feel you need to know as a beginner Yelp,Cluck, and Purr. I feel with these 3 calls you have everything you need to call a bird in. Once your comfortable with those calls you can getting into cutting, fighting purrs and combos above the above...but for now forget about throwing in the kitchen sink. NWTF.org has all the sounds on their web page and a short description..its a good start bu I would recommend a Cd and some of the ones mentioned earlier are good. My personal favorite and the one that came with my calls are the Primos CD's...Will does a great job of explaining the call, how to make the sound, and when to use the call.
Speaking of the kitchen sink, when it comes to calling I've found that less is more, especially when hunting pressured birds on public land. Keep in mind a mature Tom has probably heard it all by virtue of other hunters who aren't as disciplined and call at the wrong times or too much...I'm no exception and I learned the hard way. A Tom expects the hens to come to him...what brings him in is the tried and true female tactic of playing hard to get. So like many of the male species we tend to loose interest if we have to work too hard for it or it comes too easy...we like a little bit of a challenge and a gal that leaves us wanting more, and Tom's are no exception. Start off soft with a couple clucks or soft yelps and wait..wait a good 15-30 min before you sound off again. If the Tom responds to your calls shut up and don't call again unless he gets hung up and you don't hear him for a good 30 mins. Then you can call again and hopefully get a response and indication if he's moving in or away from you.
Lastly be wary of all the gimmicks...I fell pray to a few of these...some claim they work but if I tried it or knew someone who had, it never worked for me or them...the Squealing Hen call I believe is the one you asked about. I've never tried it and by the time it came on the market I had smartened up some and decided no more gimmicks or junk ..and IMHO the squealing hen falls in that category.
Hope this helps, and one thing I will say is there are some really helpful folks on this sight...don't be afraid to ask too many questions...no such thing here and the fellas here are all to happy to help..good luck to you this season, keep us posted on how you do.
