Tone Audio System - Fisher COIN STRIKE Operating Manual

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 Coin Strike 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 byan
"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.

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 99 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:
+0 to +8:
+9 to +11:
+17 to +18:
+20 to +22:
+28 to +30:
+30 to +34:
+34 to +51:
+60 an up:
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 iron discriminator and disc. notches can silence
the audio for certain targets, but the two-digit I.D. will
always reveal the target identity.
