When I need shooting sticks, I prefer to make my own out of slender, strong branches cut to my preferred length (for me it's 30"), joined at the crossing point about 4" from one end with a single wood deck screw, and fastened with a loose strap of 1" wide quadruple-thick camo cloth tied to both sticks about 2" above the crossing point. This provides a flexible and soft "groove" between the top branches of the sticks for resting your stock. For a really stable rest, add another 4" shorter stick joined with a short leather thong tied to both longer sticks just below the crossing point, with the thong passing through a hole drilled 1/2" from the end of the shorter stick. Either setup gives you a naturally camoflaged device that is inexpensive, easily folded together for transport, and works as good as any you can buy.
