Cheapest !!! HFD-C Water detector/ Mine Locator deep underground detector 500m depth

HFD-C Natural VLF Water detector/ Mine Locator

Use relative parameters like resistivity variation produced by benign conductors to find water. It can get water location, depth and outflow etc. It has obvious advantages: low cost, fast,high accuracy, full information, simple operation etc.

Feature:

Fast and high efficiency:Complete 4000m profile survey in a day, speed and efficiency improved 10 times than traditional method.

Easy to carry: Earth natural electric field as signal source without heavy power supply, weight ≤5kg, easy to carry and use.

Simple operation:Controlled by micro PC. Master operation within 10min. Just 2h you can finish training.

Good precision and high accuarcy:Resolution up to 0.001mV, high precision ±5%. 

Strong Anti-Jamming capacity: Advanced anti-jamming technology and multiple anti-jamming design, get good curves result even in noisy road and high electric jamming area.

Flexible array: Traditional and unique array method: Multi-array measurement: traditional and original array method, good geological effect, easy explanation. Big achievement in direction, depth and thickness of ore vein.

Technical Parameters:

Automatic noise reduction, super anti-Jamming.

Measure 3frequencies(25HZ, 67HZ, 167HZ) or 30 frequencies test synchronously.
