Aluminum snap-lock rover rod features a new one-piece design. It’s faster and easier to use compared to traditional two-piece screw-together rods, which makes it an ideal rod for all GPS RTK surveys. Highly visible exterior graduations are great for staking out "cut/fill" stakes or simply use them as a scale for offsets. The rod telescopes and can lock at two different heights, 2 m or 1.8 m and collapses to 1.343 meters. Two locking systems are featured on the rod: The snap-lock guarantees no slipping and the compression lock centers the telescoping inner and maintains straightness.  It includes a 40-minute, adjustable circular vial. The pole comes with an on-board 40-minute adjustable vial. It has a 5/8X11 thread that works with all GPS receivers and accessories. Weighs 2.4 lb (1.08 kg) Storage case included.
