WADI™-VLF EM
for water prospecting

THE WADI™

STATE OF THE ART
IN WATER PROSPECTING

SIMPLE TO OPERATE
IMMEDIATE, RELIABLE RESULTS
NO INTERPRETATION NEEDED

WADI utilizes the magnetic components of the electromagnetic field generated by long-distance radio transmitters in the VLF (Very Low Frequency) band.
These transmitters are used for long- distance communication (see map), and they operate at 10-30 kHz. In difficult conditions a portable VLF transmitter may be used instead. Conductive structures on the surface or underground, even when covered with thick overburden, affect locally the direction and strength of the field generated by the transmitted radio signal. WADI measures the radio signal distorsion and presents the result directly on a display screen.
See the new RAMAG data transfer and analysis software package for WADI data.

Where the signal from these stations is too weak the
TX27 portable VLF transmitter may be used to provide the signal.
