On my backpack hunts, I take the "Backpacker" by Grizz Targets and Archery. It doubles as a flat cook surface and a glassing pad. It weighs 2.5 lbs and is made from high density foam. It is designed with strings built in so you can hang it to shoot it. The design is built so you hang it some where and when the arrow hits it, the high density foam and the swinging action absorbs the energy. I'm shooting 72 lbs, 30" draw, 453 grain arrow at 286 FPS and the arrow will only go half way though with a broadhead on
Here is the link if anyone is interested.
Targets that you can shoot Broadheads and Field Points at from Large Range Targets to Small Back Packers.
