GD-C Natural VLF water detector is a design that refers advanced technology homeand abroad, solves great subjects on shielding and selective signal processingto amplify in complex natural electric field, and also does multipleanti-jamming as well.
GD-C Natural VLF water detector is similar to traditional resistivity prospectorgenerally, the biggest difference is applying natural electric as field sourceand removing heavy power supply, the total set is no more than 5kg. Its mainfeatures are simple operation, easy to carry, high accuracy, fast speed,flexible array etc. The speed is 10 times more than traditional DC resistivityprospector, and it is your useful assistance in ore prospecting. More than 20years' practice proves that it is a state-of-the-art portable earth resistivitymeter and gains customers' common praise.
2.Principle
GD-C Natural VLF water detector uses relative parameters like resistivityvariation produced by natural electrical field and different geologicstructures(underground water is benign conductor)to determine the water(bedrockfracture water, carst water, pebble bed water etc.) we are seeking. It can knowrelative information like water location, depth and water outflow etc. Comparingto other water detectors, it has obvious advantages: fast, high accuracy, checkfull information, portable, simple operation and so on.
3. Mainapplication
1. Applied in underground water detection to meet the demand of drinking water,industrial usage and agricultural irrigation.
2. Widely used in metal oreprospecting, non-metal ore's detailed and general survey to decrease the ventureof mineral investment and improve exploration success rate andscientificalness.
3. Also used in engineering geological prospecting,disaster geological detect, coal goaf, archaeological mining, city exploration,non-metal pipe survey as well.

4. Mainfeatures
1. Fast and highefficiency:
Completeabout 4000m profile measurement in one day to realize geological abnormity indifferent depth, the prospecting speed and efficiency is improved about 10 timesmore than traditional resistivity method.
2. Easy to carry:
Without heavy power supply, it uses earth naturalelectromagnetic field as signal source, and the weight of complete set is lessthan 5kg so easy to carry and use.

3. Easy operation:
Equipment is automatically controlled by microPC. You can learn its operation in 10 min. It will take 2h for person withoutprospecting experience to finish the relative training.
4. Good precision and high accuracy:
It will do measurement withresolution up to 0.001mV, high precision ±50%.
5. Stronganti-jamming capability:
You can get good curves result even innoisy road and high electric jamming area for signal via frequency selector anddigital processing.
6. Flexible array—traditional and unique array method:
It hasmulti-array measurement method: traditional and original electrode array method,which has good geological effect and easy explanation. It makes big achievementin solving problems about the direction, depth and thickness of orevein.
