This electronic transit features a dual digital readout and measures horizontal and vertical angles using an incremental encoder detection system and vertical compensator. Key operation is very simple, and all angle readings are displayed digitally on an LCD window. The telescope optics produce a bright, erect, 30x image. Also comes complete with a 3x optical plummet which produces an extremely bright, clear image. Other features include a built-in display and crosshair illuminator for low light conditions; clockwise or counterclockwise horizontal angle measurement options; vertical angle measuring: provides three different options plus percent grade; automatic power shut-off with three options: none, 20-minute, or 30-minute; optical plummet; zero resetting; and sealed construction. Hard-shell carrying case, manual, and accessories are included.
