Summit Viper SD Climbing Treestand - The Viper SD features a comfortable foam-padded seat that can be raised for bow hunting and lowered for hunting with a gun. The solid front bar allows for easy sit-to-stand climbing and works well as a gun rest. The Viper SD is also highly portable with a frame that nests together and packs on your back. The Viper SD comes complete with a 4-point safety harness, RapidClimb Stirrups, and all necessary pads, hardware, ropes and straps. Built to last, the Viper SD is covered by Summit's Five Year Limited Warranty. A popular climbing treestand since its introduction in 1998, the Viper SD has been noted for its unique blending of shape, innovative cable attachment system, ease of use, and portability. The original Viper has been updated with aluminum construction, a more comfortable seat, QuickDraw cable attachment, RapidClimb Stirrups, Bent Cable arms--and--the most recent innovation--sound deadening (SD) technology to minimize noise that may compromise your concealment.
