  • Rugged, waterproof/dustproof magnesium-alloy housing
  • 28 hour battery life (eco mode)

Advanced design with superior technology

The GM-100 series was designed from the ground up to deliver the very latest technological advantages, all in a small, sleek design – you’ll appreciate the advantages from the very first measurement.

Featuring a best-in-class EDM unit, the GM-100 is able to measure up to 6,000 m 1.5 mm + 2 ppm to standard prisms, and up to 1,000 m at an incredible 2 mm + 2 ppm accuracy in reflectorless mode.

Measurements are captured faster than ever, and with a beam width of 13 mm (over 30 m), the bright red laser dot pinpoints features with ease.

A world’s first – TSshield

Topcon is proud to offer another world’s first technology in all GM-100 total stations – TSshield. Every instrument is equipped with a telematics-based multi-function communications module providing the ultimate security and maintenance capabilities for your investment.

If the activated instrument is lost or stolen, send a coded signal to the instrument and disable it – the total station is
secure anywhere in the world.

In the same module, you have daily connectivity to cloud-based Topcon servers that can inform you of available software updates and firmware enhancements.
