Here is another type. This one uses magnets. I plan on using something similar this year.
I will probably remove the magnets and wrap my limbs. Tying off at the rister and then near the cam pockets.
Dicks Sporting Goods has something similar for $9 but I do notice that the item is not available on-line.
