The Sokkia 5.1-Foot Pro Series Mini Aluminum Prism Pole 808043 provides surveying professionals with two adjustable sections and dual graduations in feet, tenths, and hundredths of a foot and centimeters. This mini prism pole is solid red, extends to 5.10 feet, and collapses to 2.70 feet. Two twist knob locks are present for securing the prism pole's length. A 5/8 x 11 thread on top of the prism pole is ideal for mounting prisms. The adjustable tip makes it possible to change the height of the mounted prism. And a convenient 40-minute level vial built into the prism pole simplifies keeping your prism pole level as you work. Lightweight aluminum construction makes this prism pole weigh in at just 2.3 pounds while resisting common wear and tear.
