re: deer hunting light advice

(joke)

I've got 2 headlamps like this. I really like them. They hold a long charge and are very bright. I've used it to track a wounded deer a few hours at night. I'd buy 2 extra batteries and a wall charger so you'll always have an extra set of fully charged batteries. Like mine, this item has accessories to charge the batteries using a USB port, cigarette lighter or a wall charger
