342 Topcon Positioning Group’s latest reflectorless total station is built to go farther than ever before.

“Measuring the long distance is the key new feature,” said Jan Balkema, account manager with Topcon.

The GPT-3500LN is a reflectorless total station for the construction and mining market. With a measuring distance of 2000m, the GPT-3500 is designed to measure farther than any non-prism instrument in its class, Topcon said.

“Incorporating the Topcon advanced time-of-flight pulse technology, the EDM is fast and powerful,” said Ray Kerwin, director of global surveying products.  “The Topcon algorithm filters signal noise to provide accurate measurements even on dark and wet surfaces, where other reflectorless technology might fail.”

Along with its onboard data collection software, the GPT-3500LN can connect to an external field controller, enabling field-to-office connectivity with the MAGNET suite of software solutions. The system also can be paired with a prism to allow for a measurement range of up to 3000m.

Additional features include an IP66 rated design, on-board TopField application software, and battery life of up to eight working hours.
