I use this bench. (full disclosure) I designed it after shooting pd's for 20+ years. I get nothing if you buy one, my son sold this company to the present owners. It is the 3rd or so variation which I have used every year on my pd hunts. It incorporates what I believe are the most important things in a bench. Smooth rotation, with no stick-slip or chatter, so you can make windage adjustments an be on target, (It has a bronze rotation bearing) and a rigid table (13 or 14 layer CNC cut Baltic Birch Plywood). Having the leg length, seat height and forward & back location adjustable, and plenty of room to rest your elbows while glassing for dogs. The seating position is very close to the center of rotation, so you don't have to worry about leaning back, and the table falling over. It sets up quickly, and is a stable rigid shooting platform.
