[With Calibration Certificate] TOPCON GTS-310IIA Total Station Detachable Type [Used] We also have a large selection of total stations and surveying instruments available!

Please let us know if you require an estimate or receipt.
We will flexibly accommodate your needs.

Smooth and reliable sighting
All fine-adjustment screws and locking screws utilize a coaxial design to ensure reliable sighting with one hand.
The lower fine-adjustment screw features a sliding cover.
By requiring the cover to be slid only when needed, it prevents accidents where the horizontal circle is moved unintentionally.

●Interface & Power Connector
●Hand-grip type internal power supply
●Integrated Distance/Angle Measurement
●Horizontal Angle 0-Set Mechanism
●Auto Cut-Off Function
