Here is a very simple device that makes life a little easier on those days when you'd rather not be doing two things at once. It's called the Boom Boy.

It will hold any standard size boompole for hours without complaining. Your boompole is protected from scratches with the soft plastic coating while also being lightweight and small enough not to be a hassle to pack in your kit. The stainless steel post will mount to any "C" stand head or super clamp commonly found with most crews.
