REDDING, CA - SECO Manufacturing Company, Incorporated recently introduced new portable sliding mini prism and pole kits. The kits consist of a unique sliding 0-offset mini prism with a target design which can eliminate pointing errors that are normally associated with 0-offset prism configurations. The kit also includes four 1-foot screw-together pin pole pieces-each pole section includes a 0.5-foot mark around the outside diameter of the poles which allow the height pin to find known heights. Other components include a replaceable point and an adapter for standard 5/8 x 11-threaded pole tips or tribrachs (both sold separately). The kit organizes nicely within the system bag for storage or easy transport.
The prism assembly features a 25-mm, 0-offset, silver-coated prism. The high-quality anodized aluminum housing holds an adjustable 40-minute vial on top and features dual-purpose white site cones on its sides. These vertical angle site cones double as locks; one locking the prism tilt angle and the other locking the vertical height of the prism on the pole-a pointer in the cone axis allows accurate height measurement.
These new kits come in standard survey or metric versions and will soon be at SECO dealers worldwide.
