Main principle
NEF800 Natural VLF Prospector uses relative parameters like resistivity variation produced by natural electric field and different geologic substance to determine the geological abnormity we are seeking. Through the relative physical parameters variation like different conductivity between ore and non-ore object, it can get the relative information as ore vein direction, buried depth, thickness and deposit etc. In more than 20 years' practice, we gained outstanding achievement and customers' common praise.
 
Application:
1. Widely used in metal ore prospecting, non-metal ore's detailed and general survey to decrease the venture of mineral investment and improve exploration success rate and scientificalness.
2. Applied in underground water detect to meet the demand of drinking water, industrial usage and agricultural irrigation.
3. Also used in engineering geological prospecting, disaster geological detect, coal goaf, archaeological mining, city exploration, non-metal pipe survey as well.
