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 Excel 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 P/P (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.
