Electromagnetics VLF

VLF is a low-cost electromagnetism solution for mapping shallow conductors. This technique uses existing transmitters that are used for communications with submarines. The frequency used is approximately 20 kHz, which in radio transmission corresponds to very low frequencies, hence the name of this technique (VLF). The VLF technique allows the detection of conductors on the surface, but also as a tool to determine structures, faults, fractures.

Rapid acquisition

Use of existing transmitter antennas and easy to use device.

Low cost

A single operator with a system installed on a backpack to cover several kilometers in a day.


Technique to quickly identify conductors, structures, faults, fractures in the upper layers.
