Though I rarely post anything on this site I thoroughly enjoy reading! However, this subject needs some attention. I hunt at least 5 mornings a week and have killed 5 in AL 2 in GA and called up 8 more for friends that met their maker. I am 100% sure at least 5 of those would still be alive if I did not have a Haint!!!
I will admit it is probably one of the most difficult calls to blow, but once you get it right it is DEADLY! It will occasionally scare one off, but older birds or one that is really fired up that just hangs up, they just can't take it!
They make a wooden one and a plastic one. The wooden one is about $15 more, but it is much easier to blow.
