4 TONE AUDIO SYSTEM
11
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.
