no pics at the moment, but pretty simple concept- the tether ball is a roughly 8 inch diameter ball (about the same size as your old school playgrould tetherball) that slides on to the tether via a hole straight through it (one on each tether). the ball is something like a foam float, initially i was thinking it could be brass, but tht's too heavy. This'll keep your tether about 4 inches from the tree at all times, perfect distance to get a good toe hold on the tree, and once you're way up at hunting height, you'll find that having a set of big balls comes in handy. Willing to license the idea if one of our vendors wants to produce them. any takers?
