I got it specifically to use on my monopod as well as on a car door window clamp. I had to go thru a bit of a learning curve Re: working it thru three planes of motion, clamping it in position, and operating the camera/scope combination. It's my first ball-head, but now that I'm used to it, my monopod sees a lot more service than it used to.
Buying this ball head for my old tripod make me want to buy a new tripod.
