The carbon fiber and aluminum construction makes these robotic poles up to 30% lighter than similar poles. Highly visible exterior graduations are great for staking out "cut/fill" stakes or simply use them as a scale for offsets. It's perfect for use with GPS or robotic total station. The two stage 5/8 X 11 threaded tip adjusts for accurate height. Locking pin can be used for set height at 6',7',8',8.5' or for metric 1.8m,2.0m,2.2m,2.4m,2.6m. This pole telescopes to 8.6 ft (2.62 m) and collapses to 4.66 ft (1.42 m) Weighs 2.3 lbs (1.04 kg). Carrying case included.
