USING THE AML PRO
Practice on a Known Object
Signal Penetrates Deeper Through High Density Materials

AML PRO SERIES
The proper operation of the AML Pro requires
a lot of practice. We advise that you practice
on a known buried object like a culvert pipe
or other partially exposed objects. Once
the principles of operation are understood,
acquiring a technique is relatively simple with a
little practice. Factory training is available and
highly recommended.
The depth of the AML Pro transmission signal
varies with the type of soil. This unit can be
used in various material types such as water,
snow, red-clay, and does not have some of the
restrictions of ground penetrating (GPR) radar.
The AML Pro has 32 sensitivity settings with
setting 32 being the strongest. The transmission
signal will penetrate deeper through high density
materials such as concrete, clay, asphalt, or
highly compacted soil; and less deep in sand,
granular soil, or recently backfilled soil which
tends to absorb some of the return signal.
IMPORTANT: The AML Pro is water-resistant,
not water-proof.
