All Tones (At) - Minelab EQUINOX 900 Instruction Manual

Tone Pitch (Advanced Setting)
ADJUST TONE PITCH — ALL TONES
When All Tones (At) is the selected Target Tone setting, the Tone Pitch Advanced Setting behaves similarly to the 2-Tone
Setting — however instead of all targets in each region playing at the set pitch, this value sets the pitch for the first ID in
that region� Pitches then increase across the range for the other ID's�
The pitch of the ferrous region has a range of 50 Hz�
ƒ
The pitch of the non-ferrous region has a range of 500 Hz�
ƒ
You can configure the starting points to create a continuous range of pitches from ferrous to non-ferrous targets, or you
can create a Pitch Gap, in order to better differentiate between ferrous and non-ferrous targets�
The examples show how adding a pitch gap makes it easier to hear a clear difference between ferrous and
non-ferrous targets�
Default Tone Pitch Gap
(1, 20)
Ferrous targets will be very
low-pitched� Non-ferrous
targets will sound distinctly
higher-pitched than a
ferrous target with a similar
Target ID�
Maximum Tone Pitch Gap
(1, 25)
A greater difference in
Pitch between ferrous and
non-ferrous targets gives
very easy differentiation�
Small Tone Pitch Gap
(11, 12)
No clear difference in pitch
between ferrous and non-
ferrous targets� They may
be indistinguishable from
audio alone�
