I have posted on this other spots, but deer are all different, and you have to get the right deer, but one of the writers for deer and deer hunting, wrote me back about this question last winter. He has many trophies to his credit so I listened.Also nice enough to personally write me back, which few ever do. He said be very careful blind calling. He said he only called if he saw a buck. Said for every 1 you might call ,he believed you spooked 9. I refrain from this now. I am not high in the tree tops, and where I hunt deer could easily sneak around behind and eventually get my scent. Also I think depends how wary your deer are. On large tracts, where there is not much pressure, like hunt videos, bucks prob not so cautious. Where I hunt,,,lots a bow hunters.
