The Barska Accu-Grip Handheld Tripod System has a 1/4 in.-20 stud as well as a retractable video pin on its top surface. This allows for a sturdy attachment (via the thumbwheel) of the tripod system to any camera, small camcorder, binoculars, or spotting scope with a standard 1/4 in.-20 thread at its bottom. There's also a 1/4 in.-20 thread at the bottom of the Accu-Grip handheld tripod system, which allows you to attach your mounted camera/scope to a tripod or head. Using the handheld tripod system provides stability and maneuverability to your camera movements.
