High-Speed Distance Measurement Meets All-Day Battery Endurance

Streamline routine boundary surveys and construction layouts with zero operational downtime

Executing high-volume topographic surveys and construction stakeouts requires an instrument that captures points rapidly without battery depletion. The Topcon ESN-100 features a phase-shift EDM capable of measuring distance points in as fast as 0.9 seconds in fine mode. Its non-prism mode measures target objects accurately up to 500 meters away, allowing surveyors to capture inaccessible structure walls, electric poles, and steep slopes safely from a distance.

Powered by an optimized energy-management circuit, a single rechargeable Li-ion battery powers the ESN-100 for up to 28 continuous hours—allowing field crews to complete multi-day field assignments without stopping to swap or recharge batteries.

Enterprise-Grade Features for Everyday Surveying Workflows

Engineered for high field productivity, intuitive operation, and long-term durability:

• Ultra-Fast EDM (0.9s Fine Mode): Delivers rapid distance readouts on standard prisms up to 4,000 meters and non-prism surfaces up to 500 meters.

• Class 1 Bluetooth® Wireless Connectivity: Wirelessly transfers spatial data directly to field controllers or handheld tablets running land surveying software without cable clutter.

• Rugged IP66 Weatherproof Design: Protected against heavy torrential rain, windblown dust, and extreme temperature fluctuations common across demanding construction sites.

• Dual Graphic Displays & Backlit Keypad: Ergonomic dual-display interface with an alphanumeric keypad enables quick data entry and clear menu navigation under direct sunlight or low-light conditions.
