I try to imitate what another deer would sound like. To start out the deer are usually on the down wind side of trees so they can smell what is in the trees and see what is coming their way from downwind. I enter from the side farthest from where I think the deer will be and using a grunt call I will imitate a buck working it's way thru the forest. I walk a few steps and if I make noise I cover it with a grunt or two, then I will scrape leaves around making as much noise as I want shaking trees and everytrhing a buck would do. Then instead of a straight line I zig zag around in the trees grunting and scraping every 15 minutes or so. I have put the crosshairs on many bucks over 150 doing this. Give it a try.
