Depending on your needs, here is what I use.
Maglite 2AA size, mostly for emergency use, blood trailing, taking care of the animal you got right at dusk and like the last deer I got, keeping the bear that's circling off it and you while you gut it. Tough, lite and lasts pretty long on a set of batteries. With an optional strap it's hands free.
Petzl Myo XP. Super bright LED, AA batteries, not much worry about burning a bulb out in the dark. Uses: Early morning hikes before dawn, backpack hunts, late night return trips after dark and the other normal hunt duties. Since it’s a headlamp it’s hands free. I just bought this one so the jury's still out on it's durability.
