The range is pretty close for the motion detection and I’ve had the pleasure of watching mature bucks. They rarely run like the dickens unless they’ve confirmed a real danger. Curious, strange things like a flash may spook them for a moment but they’ll investigate. They may alter their path a little, but they won’t leave the area. Also, the more exposure to flashes, the less the effect.
Comparable notes are shining………….which doesn’t prevent a buck from returning to that field of does night after night………..and lightning.
I got my first exposure to the use of my new trail cam just this past Saturday and I got pics of a 3 1/2 year old (near as I can guess) and in the series, he never ran. He had his ears perked up and the nose going, but never turned during the series of pics.
The older guys usually don’t walk down the cabin driveway anyway, near as we’ve ever determined, but I don’t think a flash is enough to deter them. It doesn’t register as a danger. No scent, little if any sound, and it never moves.
Another thought is spotting that 10-12 pt. monster in somebody’s yard light! If exposure is the deterent, how do we explain that?
