I use the Stoney Point PoleCat Converta Pod System that I got from Midway USA. I use the 16" - 38" size for sitting to prone shooting. It is around $80. They also make a 25" - 62" model that is around $110. Mine is light and easy to pack and sets up quickly and is stable and I can adjust the legs so that it works well on uneven ground. Also have learned to use the third leg placed up on my shooting arm side shoulder with the bi-pod front legs supporting the forearm of the rifle while that third leg supports my shooting hand arm wrapped around the third leg. Makes a bench rest steady position while sitting. Works great with my T/C Contender pistol used this way also.
