SureFire with out a doubt. I have the Outdoorsman EL2 & would hate to not have it in my pack.
My Dad could not believe what I paid for a flashlight, then after a little rodeo with the horses on a hunt in the wilderness of Alberta & we were stuck in the woods walking out at night. We finally made it to the truck at midnight & right after it got darkI asked my Dad how much he would give me for the Surefire It was nice to know it would run all night if needed.
