Laser Pointer for Reflectorless Measurement and Layout

Point Guide for Stakeout/Layout

24-Key Alphanumeric Keyboard

Versatile On board Applications Including Road

Rugged IP66 Dust and Water Protection

Powerful 2,000m Reflectorless EDM

A refinement of GPT3502Ln Total Station advanced time-of-flight (pulse) EDM technology in the GPT-3500 allows measuring distances up to 2,000m (6,550 ft.) range without a reflector. 
This wide range reflectorless capability enables quick and efficient measuring works in the large area. Also, it increases personal safety without approaching dangerous surface.

Reflectorless Measuring for Any Targets

Powerful reflectorless measuring capability even for narrow object such as power line or tower frame of power line. 
Also, it can measure low reflection target like road and ground surface, wood, coal, and any dark color materials.
