The Trimble GDM 620S Robotic Total Station with a frequency range of 450-470MHz is a high-performance instrument designed for precise and efficient measurements in various applications. This state-of-the-art geodimeter features a robust and compact design, making it suitable for both indoor and outdoor use.
The GDM 620S is equipped with a 6-inch (152mm) diode-pumped solid-state (DPSS) laser, which delivers exceptional visibility and accuracy up to 6,600 feet (2,000 meters) in open conditions. The instrument also boasts a built-in reflectorless targeting capability, enabling it to measure distances to non-reflective surfaces, such as concrete, asphalt, and vegetation.
One of the standout features of the GDM 620S is its integrated 450-470MHz radio, which allows for seamless data transfer between the total station and Trimble's advanced field controllers. This feature significantly enhances productivity, as it eliminates the need for cables, thus reducing tripping hazards and increasing mobility.
The GDM 620S is a fully-robotic total station, meaning it can be controlled remotely using Trimble's advanced software. This feature enables surveyors to work more efficiently, as they can program the instrument to perform repetitive tasks or move to specific locations without physically being present.
The instrument is also equipped with Trimble's renowned Magnetic Compensator (MC) technology, which ensures accurate measurements even in the presence of magnetic interference. It also features a user-friendly interface, making it easy for both novice and experienced surveyors to operate.
In summary, the Trimble GDM 620S Robotic Total Station is a powerful and versatile instrument that combines precision, durability, and efficiency. Its high-visibility laser, reflectorless targeting, and integrated radio make it an ideal choice for a wide range of surveying and measurement applications.

When powered up remotely, it powers almost instantly every time. The included removable keyboard seem to be fully functional with all original programs and keys appear work for any of those hard core old school surveyors who could actually still use this collect data. All Trimble data collectors work with instrument robotic ally including the tsc3.
There are still service providers that work on these, you just have too ship them out if don't one near. This instrument is for someone who knows how reliable these 600 series instruments are, when properly taken care of. Up for sale is a geodimeter 620s fully robotic instrument.
The system up for sale includes: robotic instrument listed above one fully working external radio red light keyboard alpha cu changing channels and collations blank face plate robotic ally original case 2 antennas if interested,for an extra overall it seems was not a daily work horse. This instrument is almost flawless with 2 light scratches on handle and very fading of original finish. Instrument is fully functional and calibrated with fresh internal batteries. I could give up a working used external radio battery and single charger with cables.
The internal radio and external side cover are new old stock, as you can see in pictures that is just a little brighter. In my opinion, these instruments work almost as good and insanely accurate the new ones old are built to last longer.
