The Kirk BH-1 Ballhead with Quick Release is a rugged and well-designed
ballhead. It features the same efficiency of design and rugged construction
that make other Kirk products so popular. Weighing in at under 2 lbs, this head
is rated to support up to 50 lbs. In addition to the large single-action
locking knob, the BH-1 also features two smaller knobs. One controls the 360°
panning control, and the other the amount of ball friction.
