RE: bleat cans
it's never to late to try. when i use mine i don't let the whole sound of the bleat out. i cut the sound 1/4-1/2 off. someone on this board said that a drawn out bleat the cans produce is more of a warning sound. i folllow up the bleats with some soft drawn out tending grunts from my grunt tube. worked this year on a 6 pointer. good luck bro.
