Hawk

"The Hawk Xtendible Bow Arm is a compact bow hanger that conveniently screws into tree trunks to efficiently hang your bow where you want it. Machined out of aircraft-grade aluminum, it extends from 8-3/4"" to 16-1/2"" and weighs in at a mere 8 oz. This lightweight system can hold up to 15 lbs. Ample-sized, molded soft-grip hook rotates to the position of your choice while the patent-pending Anti-Spin TreeCam lever prevents unwanted spinning or movement of bow arm."
