7.1 Magnetometer
By selecting the Magnetometer mode from the main menu, you can scan the sub-surface for
ferromagnetic targets and areas of the soil with a high iron content. Also, you may view the oscilloscope
output on the monitor to be able to identify ferromagnetic materials in the ground.
The Magnetomer mode can be used with all the antennas except the DDV system. As soon as you
confirm the operating mode "Magnetometer", the integrated magnetometer will be adjusted to the
current ground value of the place where it is situated at that moment. During the initialization process
the message "
Ground Balance, Please Wait" appears on the display. Only after this message disappears
can you start your search.
When powering on the unit above a neutral soil, all metallic signatures will be shown in upward spikes.
If by mistake, you start the unit above a metal target, all like metals will not be recognized.
To re-balance the Magnetometer, press the
OK
button, while staying on a neutral place. To exit the
Magnetometer mode, press the
or
to return to the main menu.
When you use this mode, you can actually move quite quickly to clear a field of easily identified metallic
objects. Most of the time when your target may be of a newer nature or is located in an area where there
is a lot of modern construction, this is the first choice to identify potentially “Hot” targets. A hot target
can be debris like cans, nails, screws, old automobile parts, etc... These should be cleared first. The
magnetometer measures usually only near to the surface for quick hunts.
