LCD IDENTIFICATION SYSTEM
The LCD will also show you an indication of the type of target you
have found, independently of the audio tones, by showing you a
number preceded by a “-” or “+” sign. The target identification
system works as follows:
When in either search mode (ALL METAL or DISC), a target
will produce a number between 0 and 99 depending on
how strong that target is (either due to its size or depth).
This number is not an indication of target type, but rather
the strength of the signal that target produces. A large or
shallow target will produce a higher number than a small
or deep target. Therefore, the number readout will give
you an indication of size and depth — important when
weeding through trashy areas.
In addition, the - or + sign in front of the number can
indicate whether the target is ferrous in nature (an iron
target) / or nonferrous (a non-iron target).
1.
In the ALL METAL mode, any target that causes a minus
sign (-) on the LCD will tell you that the target is ferrous in
nature, and is either a piece of iron, iron-based steel, or
a “positive” hot rock. Any target that causes a plus sign
(+) on the LCD will tell you that the target is nonferrous
(any metal that has no iron in it). Finally, any target that
produces no plus or minus sign (but still causes a low
tone) is usually a “negative” hot rock.
2.
In the DISC mode, any target that causes a minus sign
(-) on the LCD will tell you that the target is below the
discrimination control setting (in other words, the DISC
setting you have chosen blocks this target from
producing a high tone). Therefore, targets with a minus
sign will be predominately iron and positive hot rocks.
Any target that produces a plus sign (+) on the LCD will
tell you that the target is a “good” target (again,
dependent on the DISC control setting you have
chosen). Again, a “negative” hot rock should produce
no plus or minus sign.
