* SP(self-potential) survey   &  1D Resistivity VES survey




* Underground water exploration

* Pollution monitoring and mapping

* Salinity control

* Depth-to-rock determination

* Weathered bedrock localization                               

* Depth and thickness of aquifers

* Civil engineering

* Archangeology







DC electrical prospecting is to transmitting a current I through two measuring electrodes and measuring a voltage V with two potential electrodes which can image the underground geological structures through surface electrical measurements by apparent resistivity.


Apparent resistivity:     , k is polar distance constant











* Portable and Compact

1、Power source, transmitter and receiver in a single unit

2、Total weight of the unit including the internal battery

3、 Data storage in the instrument with 8GB capacity for about 4000,000 readings

4、USB serial interface enables the instrument to communicate with computers for upgrade or data manage

* Reliability

1、Water proof , dust proof

2、Shock resistant fiber-glass case.

3、Protection: Seal, over-voltage, over-current, high-temperature, open circuit, reverse connect, leakage, lightning.

* Measurement and display of ground resistance, current, voltage, self potential and standard deviation.

* Modular Design: Hardware, Software and License are separate entity. It supports online upgrade for more functions.

* Two software platforms: GD -10 UI combined Geomative Studio data management software on PC enable the easy operation and high efficiency.
