Ferrous
Selecting Ferrous causes emitted tones
to be generated according to the target's
ferrous characteristics (the vertical axis of the
Smartfind Window, or the first number in the
Digital Screen).
A low 'blaat' tone denotes a highly ferrous
object, displayed on the bottom of the
Smartfind Window and having a high FE
number. A high-pitched 'squeak' tone denotes
a nonferrous target, displayed on the top of
the Smartfind Window and having a low
FE number.

Tip: Ferrous is often preferred by relic and
jewellery hunters as desirable low conductive,
medium ferrous targets will give a higher pitched
signal response.
It may be useful to select Ferrous if searching
in QuickMask. There is less chance of a high-
ferrous target producing a high tone signal
due to its high conductive characteristics.
To change the Sounds:
1 Press the Menu button

Variability

Range: 1–30
Factory Preset: 25
Variability controls how much the audio
pitch will change depending on target
characteristics.
A high Variability setting results in a
maximum variation of pitch from target to
target. A high Variability can aid in identifying
targets in close proximity to one another,
and is recommended when using a complex
Discrimination Pattern.

A low Variability setting results in a minimum
variation of pitch from target to target.
With a low Variability, target information is
compromised, but the target response will
be more consistent. This is recommended for
users new to multi tone detectors, or if you
are using an 'All Metal' Discrimination Pattern.

To adjust the Variability:
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 Threshold sub-menu
5 Scroll down to Variability
6 Press either the Left or Right Navigation
button to change the Variability setting
7 Press the Detect button to exit the Menu
and resume detecting
Note: Even though you may still adjust the
Variability when the No. of Tones is set to 1,
it will not have any effect on the target
audio response.
