4 TONE AUDIO SYSTEM
The four-tone audio system provides you with more information
per sweep, acting as a target I.D. system in the “discrimination”
mode. While sweeping the ID EDGE search coil over a target, you
will hear one of four tones:
LOW TONE = Iron objects (ferrous)
LOW/MID TONE = Foil, Nickel, Round Tabs
MID/HIGH TONE = Square Tabs, Zinc Pennies
HIGH TONE = Copper, Clad, Silver Coins
If a bell tone audio is heard, accompanied by an “OL” on the
LCD, the coil has encountered a larger or shallow target and the
search coil must be lifted to avoid overload and inaccurate I.D.
When hunting in the ALL Metal mode, a single tone will be heard
for any metal object the coil is swept over. This mode responds
much like the “auto tune”mode of previous detectors.
PINPOINTINg
When the Pinpoint button is pushed and held, the non-motion
pinpoint mode is activated. This pinpoint mode may be familiar
in some ways (when the target is approached, the audio intensity
increases), but different in others (the digital numeric indicator). The
two digit (0-99) LCD will help you to accurately pinpoint your target
by increasing in value as the center of the target is approached.
This gives you much more resolution in pinpointing than a “depth
estimation” system, and allows you to characterize size, shape,
and location of your target better.

LCD IDENTIFICATION SYSTEM
The LCD will also show you an indication of the type of target you
have found, in conjunction with 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 36 indicating target
type.
In addition, the - or + sign in front of the number
indicates whether the target is ferrous in nature
(an iron target) “-” / or nonferrous (a non-iron target) “+”.
The target I.D. numbers correspond
to the following target types:
All negative (-) numbers: Iron
+0 to +8:
Foil
+9 to +11:
Nickel
+17 to +18:
Square Tab/Brass
+20 to +22:
Zinc Pennies
+28 to +30:
Copper pennies, dimes
+30 to +34:
Quarters
+34 to +36
Silver
Remember, this Numeric I.D. system is activated in either
the All-Metal or Disc. modes (although the 4-tone audio
I.D. is only active in the Disc. mode).
Also, the discriminator can silence the audio for certain
targets, but the two-digit I.D. will always reveal the target
identity.
