erences. Many other types of metal can

common metal objects. It is impossible to
classify all buried objects accurately.
2. Depth Indicator
The Depth Indicator is accurate for coin-
sized objects. It indicates the relative
depth of the target. Large and irregular
-
ly-shaped objects will yield less reliable
depth readings.
When passing over an object, the depth
indicator will light up and stay illuminated
until another object is scanned. Repeated
indication at the same depth level indi
-
cates an accurate target detector. If the
depth indication varies with each sweep,
try sweeping at different angles; there
may be more than one target present.
With practice, you will learn the difference
between accurate readings, multiple tar

gets, and highly erratic readings which ev

NOTE:
Depth value indication of same
target in air is different from that of under
the ground.
