I was just reading another thread regarding Grunting bucks. I've read a few times now tet when folks are grunting or calling deer, the deer hones straight in on the sound & looks directly at the caller.
Having never, ever grunted or called anything bigger than a bunny I'm not 100% sure how the calls work, but I'm presuming that you blow 'em.
THE IDEA.........
Would it be possible to attatch the call itself to another tree, that you're not in & attatch a suitable length of garden hose. You'd use the call by blowing down the hose & the sound would actually come from, say, 10 yards away. That way if the buck/doe/goat/skwerl/mouse stares straight to the sound, it's not looking at you, but the tree the call is strapped to.....
Told you, dumb as a brick, but I hadta ask! :D
