I have one that I use at the range sometimes when shooting steel. I don’t think I’d use it for hunting. It gets in the way of the diopter adjustment and magnification ring on my scope, adds weight and hangs up when casing the rifle. Also, you’d have to remember to turn it on in the heat of the moment. It clamps on the scope and you want it just tight enough to stay in place without damaging your tube, so if you’re bumping your rifle around getting in and out of the truck it’s probably going to move around some. It will get some cool video, but if you decide to take it into the field it’s gonna take some attention to make it all work for you.
