The bi-directions design in multi-electrode cable and cable leader enable the innovation on the connection of electrodes and ensure multi-function in one unit.




2. 2D/3D rolling measurement

2D/3D rolling measurement enable limited cable for long-section measuring point is not repeated extremely high efficiency.



3. Geomative Studio Software
The software of GD-10 Multi-function DC Geo-electrical Res/IP System includes two parts: the embedded software UI in GD-10 mainframe and Geomative Studio on PC. The two parts combined as a new way is available to break through the limits of tradition system enable the system with powerful software.


Geomative Studio is the whole data management platform including device management project management and script management.
  Device management: manage device according to online device and offline device;
  Project/Data management: manage measuring project according to different levels as “ project-zone-task”;
  script management: classify manage according to 1D script 2D script 3D script which can edit advance and store in mainframe by USB port then recall during filed work onsite.



4. Optimized Accessories
All the accessories of GD-10 system are optimized carefully as star-like electrode connector of cable BP-145 all will be helpful to improve the field working efficiency.
