Hunt Safer, Have a Wingman. The TreeStand Wingman is a tree stand hunter's new best friend. Its unique system is designed to allow a hunter to descend slowly to the ground after a fall from the tree stand. The best part is it can be used over and over and over. It is designed for hunters between 70 and 300 pounds and each one is factory tested. The device is designed to be used with an existing TMA safety harness (not included) and eliminate the possibility of getting stuck while suspended halfway up (or down) a tree. It also reduces the impact force by 66% compared to typical lanyard systems. Comes with a gear bag for travel.
