The target indications are just that: visual references. Many other types of metal can fall under
any one of these categories. While this metal detector will eliminate or indicate the presence of
most common trash, it is impossible to class all buried targets accurately.
Depth Indicator
The depth indicator is accurate for coin-sized targets. It indicates the relative depth of the target. Large
and irregularly-shaped objects will yield less reliable depth ratings. 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 indicates an accurate target detection. 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 targets and highly erratic
readings which evidence trash or irregularly-shaped objects.
