Product Manual

USING THE AML+
Operation of the AML+ is technique
sensitive. We advise that you practice
on a known buried object like a culvert
pipe or other partially exposed objects.
Once the principals 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+ transmission
signal varies with material substrates.
The more dense the material, the
further the signal travels. This unit can
be used in various substrates such
as water, snow, red-clay, and does
not have the substrate restrictions of
ground penetrating (GPR) radar.
The AML+ has nine sensitivity
settings, with setting 9 being the
strongest (see gure 9-1). However,
the density of the material will
inuence the depth of the transmitted
signal. The transmission signal will
penetrate deeper through highly
reective materials such as concrete,
clay, asphalt, or highly compacted
soil (see gure 9-2); and, less deep
in sand, granular soil, or recently
backlled soil that tends to absorb
some of the return signal strength
(see gure 9-3).
IMPORTANT: The AML+ is water-
resistant, not water-proof. Cover
the unit with a clear plastic bag if
operating in wet weather conditions.

Note: Signals travel further in more
dense and highly reective materials.
Note: Level 9 provides the highest
sensitivity setting, 0 the lowest
sensitivity setting.
