I'm sure I'm not the only one here but I have no need for a bipod. Sure, I have one that I bought 25-30yrs ago, that I used for a little while ('cause it was cool, I suppose) while shooting from the bench. I discovered my groups were way better with a front rest and rear sandbag.
Hunting here in Eastern N.C., there's not a lot of places I want to plop down on the ground. Fire ants, copperheads, rattlesnakes and "cat-claw" briars abound. My neck as been fused since 2005, so it's not the most comfortable for me either.
My style of hunting (read as "shooting") is usually either fast paced with hounds, shooting off hand as they streak across pulp wood roads or harvested crop fields, to setting in a shooting house with a sand bag for the forearm and a shooting stick about the toe. This is steadier that I thought it would be and enables me to kill deer to the limit the current property allows, which is just under 600yds. The owner of the property has a nice office chair in the house, which is adjustable for height and tilt.
With all that, I will agree they are very useful tools/rest, in the right situation and in the right hands.
