Cambo's precision-geared movement has important advantages over standard friction-locking ball heads and other 3-D schemes. Minute adjustments are precise and controllable, and because movement is geared, it is self-locking. The Cambo 3-D Gearhead provides 140° of self-locking tilt, 90° forward and 50° back. 180° manual side-to-side tilt movement features adjustable resistance. Mounts to universal 3/8" threaded tripods.
