The Summit Viper SD Climbing Treestand is an extremely popular treestand, but it can be tough to find a good deal on one. The Viper SD sets the industry standard for climber stands. It has aluminum construction, utilizing Dead Metal Technology to reduce noise. The Quickdraw triggers allow you to slide in the cable to the desired diameter without messing with pins or buckles. The padded suspension seat can be raised and lowered for gun or bow hunting. The Viper SD retails for $289.99 and I rarely see it sold for under $250. Another option is the Summit Viper SD Mini if you want something a little smaller and lighter.
Thanks to FlyGuy on the Rokslide.com gear forum for pointing out this great deal.
