TF 900
This
system records with a new design and method in order to detect metals,
hollows in depth of the ground. One of the separatable elements of this
system is that detection according to VLF frequency and for this you can
find you can find so many cables, pipes, and Treasures Troves under
ground because of so much permeability of this frequency. Experiences
show that the best frequency for detecting Cables and pipes is 12.5 KHz.
