Designed for multiple applications such as high seats, tree stands and ATVs, the Pro Clamp works with the Spartan Davros head and other ball heads to provide secure and stable support for cameras and other optical equipment. Designed to attach to flat and rounded surfaces, devices can be mounted on three 3/8”-16 and four ¼”-20 threaded holes. Small and compact, the Pro Clamp will fit into a pocket or rucksack.
