Anyone around had experience with moose calls? I rx'd one I ordered today and esssentially all it is is a megaphone. In the instructions it states you have to vibrate your lips to make the sounds. No reed or diaphram at all. Is this the way all of them are? So far, I've had zero luck in getting any realistic moose sounds out of it. If I had it to do over again, I would just make one, with no sound producing device in it, there's not much to it. Thanks For Any and All Comments Ray
