It is similar to traditional resistivity prospector
generally, the biggest difference is applying natural electric as field source
and removing heavy power supply, the total set is no more than 5kg. Its main
features are simple operation, easy to operate, high accuracy, fast speed,
flexible array etc. The speed is 10 times more than traditional DC resistivity
prospector, and it is your useful assistance in ore prospecting.

Principle

    DSHD-C Natural VLF water detector
uses relative parameters like resistivity variation produced by natural
electrical field and different geologic structures(underground water is benign
conductor)to determine the water(bedrock fracture water, carst water, pebble
bed water etc.) we are seeking. The instrument 
can realize relative information like water location, depth and water
outflow etc. Comparing to other water detectors, it has obvious advantages:
fast, high accuracy, check full information, portable, simple operation and so
on.

Main Advantages

  
1. Fast and high efficiency:

Complete about 4000m profile measurement in one day to realize geological
abnormity in different depth, the prospecting speed and efficiency is improved
about 10 times more than traditional resistivity method.

   
2. Easy to carry:

Without heavy power supply, it uses earth natural electromagnetic field as
signal source, and the weight of complete set is less than 5kg so easy to carry
and use.

   
3. Easy to operate:

Equipment is automatically controlled by micro PC. You can learn its operation
in 10 min. It will take 2h for person without prospecting experience to finish
the relative training.

  
 4. Good precision and high
accuracy:

It will do measurement with resolution up to 0.001mV, high precision ±50%.

   
5. Strong anti-jamming capability:

You can get good curves result even in noisy road and high electric jamming
area for signal via frequency selector and digital processing.

   6. Flexible array—traditional and unique
array method:

It has multi-array measurement method: traditional and original electrode array
method, which has good geological effect and easy explanation. It makes big
achievement in solving problems about the direction, depth and thickness of ore
vein.
