The idea does not sound realistic to me, at least in NJ.

First off, IDO think it's unfair on the animals bahalf to use a flashlight to temporarily freeze the deer until you get into your tree.

Having said that, I've used a flashlight to get my tree in the morning hours since I've started hunting.......Knowing full well that any deer in Jersey that sees a flashlight, even tiny ones(flashlight), is long gone before the beam even hits the eyes. Our deer don't tolerate lights very well. That's why I cringe every time I have to walk to a spot in the dark using my light.(and believe me its tiny, it's actually a pen light, just bright enough to see where I'm stepping). Even using the pen light, you get the occational crashing of hooves in the distance. I just keep saying to myself they were a buch of fawns.

I can't imagine a mature buck being hitfrom 50-60 yds(or less)with a light, and not blow right out of the area.

Maybe it's just my state.
