Extended Non-Prism Range with Class I/1M Safe Laser
A refinement of the Non-Prism EDM in the GPT-3200NW allows measuring distances up to 1,310ft. (400m) range without a reflector. Incorporating Topcon’s advanced time-of-flight (pulse) technology, the GPT-3200NW offers both of superior performance and maximum safety with its Class I (FDA) / Class 1M (IEC) safe laser. This allows safe use even in areas with heavy traffic.
TopField / Road Software with Alphanumeric Keyboard
The onboard “TopField” and “Road” software dramatically increases efficiency in topo data collection, construction layout, as well as road stakeout tasks. The 24-key alphanumeric keyboard allows for quick inputting of point numbers, codes, attributes, and other necessary data.
