Flashlights have gotten me busted too many times to be of any use , even when using a red lens , so anymore I just wait until it's barely light enough to see without stumbling too much and go on in . Any deer that get scattered by my approach will either come back after awhile or be replaced with deer later on that have no idea that I'm there waiting for them . The exception to that is when I'm hunting public land , then I just use my flashlight or headlamp since I'll be entering the woods a few hours before the suckers...er...fellow hunters who'll be driving the deer toward me get there .
