15 km ranging · ±1 m accuracy · 7× optics · 1064 nm Nd:YAG
The ERDI WT15 is a handheld binocular laser rangefinder built around a 1064 nm Nd:YAG laser source. It measures non-cooperative targets out to 15 km with an accuracy of ±1 m, and reports slant range, horizontal distance, vertical distance, inclination angle and (optionally) azimuth. The all-metal, fully sealed housing is designed for continuous field use from −40 °C to +60 °C, and the standard RS232 interface allows the unit to feed distance data into an external recorder, mapping system or fire-control computer.
Typical applications include topographic and geodetic survey, power transmission line and cable routing, oilfield and mining site measurement, railway and highway construction survey, forestry inventory and long-range observation from a fixed or mobile position.
