Strong yet lightweight Topcon carbon fiber bipod is ideal for use with any prism pole or GPS rover rod. This thumb-release heavy-duty bipod accommodate range poles up to 1-1/4" in diameter so you can clamp the pole into place without lifting and threading it through the bipod head. The bipod provides added stability, which is particularly useful for high accuracy mapping to ensure the antenna is held still. Thumb release lock design allows locking tensions to be adjusted without disassembling the legs. Legs extend to 72" (1.8 m) for use in uneven terrain and collapses to 44 inches (1.1 m). Weighs 3 lb (1.36 kg). Storage bag and legs clip included.
