Sounds
Range: Conduct or Ferrous
Factory Preset: Conduct
The Sounds setting allows you to set
the detector to emit a distinct audio
response based on either a target’s ferrous
characteristics or its conductive properties. To
test your selection it is necessary to move the
coil across one or more targets with different
conductive and ferrous characteristics.
Note: Even though you can still adjust the
Sounds when the No. of Tones is set to 1,
it will not have any effect on the target
audio response.
Conduct
When Conduct is selected, audio tones are
emitted according to the target’s conductivity
(the horizontal axis of the Smartfind Window,
or the second number in the Digital Screen).
A high pitched signal denotes a large, highly
conductive object with Target Crosshair
displayed near the right of the Smartfind
Window (or near a CO number of 50).
A low pitched signal denotes a small object
with low conductivity; the Target Crosshair
is displayed near the left of the Smartfind
Window (or near a CO number of 1).
Tip: Conduct is often preferred by coin hunters,
as desirable targets such as gold, copper and
silver coins will give a high tone signal response,
compared to low conductive junk targets such
as foil and pull tabs.
Tone ID
The Tone ID sub-menu allows you to define
how the tone of the audio varies when
different target characteristics are detected.
This can be a very useful feature in identifying
targets close to each other.
Number (No.) of Tones
Range: 1, 2, 4 or Multi
Factory Preset: Multi
You may select how many different tonal
responses there are while detecting.
These are:
– 1; all sound is monotone,
– 2; all sound is duo tone i.e. low and high,
– 4; four different tones ranging from low
to high,
– Multi; multiple tonal responses to different
target signals.
The Factory Preset number of Tones is set
to ‘Multi’, giving multiple tonal responses to
different targets.
To change the Number of Tones:
1 Press the Menu button
2 Scroll across to Audio (using the Right or
Left Navigation button)
3 Scroll down to Tone ID (using the Down
Navigation button)
4 Press either the Left or Right Navigation
button to enter the Tone ID sub-menu
5 Scroll down to No. of Tones
6 Press either the Left or Right Navigation
button to change the No. of Tones
7 Press the Detect button to exit the Menu
and resume detecting
