SECO Manufacturing Company Incorporated brings another innovative product to surveyors--the Mini Prism Stakeout Prism Kit.
The SECO stakeout prism is now in "kit' form, which allows the surveyor to handle several surveying tasks from topos, stakeout, and construction handheld applications. The white site cones on the X- and Y-axis help improve instrument centering at the crosshairs for vertical and horizontal pointing. Moreover, the horizontal site cones double as tilting axis locks. The heavy-duty, white point can handle the abuse of being on the bottom of a pole, or used for handheld applications as well. An adjustable 40-minute circular vial, mounted at center-front provides easy viewing.
The white adapter makes the prism height 115 mm for use with most standard prism poles. This easy-to-use kit features four height configurations: 50 mm, 100 mm, 115 mm, and 150 mm, top or bottom of a pole, handheld, or tribrach mounted.
The 25 mm copper-coated prism is moisture-resistant and has good range: 3000-to-4000 feet is common with most instruments. The kit features 0 or -30 mm prism offset positions.
The kit weighs right around a pound and comes with a heavy-duty padded case.
