DGPS-RTK-GNSS
Built with a full metal jacket and a powerful dual internal battery, the Pathfinder T28 handles challenging environments and comfortably performs your day-to-day work.
Pathfinder T28 uses the knowledge of each Sanding developer. It was built not only with the world-class GNSS motherboard, but also with all kinds of tough conditions. The metal body has an exceptional level of protection and an outstanding thermal distribution.
Rover, base and static modes can be changed in seconds. WebUl can help to achieve wireless work in the office or field. The OLED display allows the Pathfinder to run day or night. Pathfinder meets all your expectations. If there are any problems, the internal components can be self-controlled or returned to the factory settings.
