Topcon DT100-L Series Digital Laser Theodolites

Topcon is proud to introduce the DT-100L series of digital theodolites. The DT-100L series includes a built-in 633nm laser diode that can be seen up to 50 meters /164 ft. away in daylight.The instrument allows the user to turn any angle desired and switch the laser on when needed. The DT-100L can be used with or without a rod person because the laser is fully visible to the naked eye. The DT-100L series consists of three models: the 5" DT-102L, the 7" DT-103L, and the 10" DT-104L.
