A Threshold tone is the constant background
sound that is a useful for hearing faint target
responses�
Threshold Level changes are global, with a separate setting
for Gold* Mode�
The Threshold Level setting has a range from 0 to 25�
The default Park/Field/Beach Modes Threshold Level is
0 (Off)� The default Gold* Mode Threshold Level is 12�
ADJUST THE THRESHOLD LEVEL
1. Press the Settings button to navigate to the Threshold
Level setting�
2. Use the Minus (–) or Plus (+) buttons to adjust the
Threshold Level� Adjustment takes effect immediately,
so listen to the audio to select your preferred level�
With the EQUINOX 900, the pitch of the threshold
tone can be set higher or lower via the Threshold Pitch

'REFERENCE' THRESHOLD TONE
The Park, Field and Beach Modes use a simplified
'reference' threshold tone� Unlike the 'true' threshold tone
that is used by the Gold* Mode, the 'reference' threshold is
a simple continuous background tone that blanks when a
rejected Target ID is detected�
Without a reference threshold, a rejected target detection
would be silent, and you would not be made aware of the
target's existence�
For typical treasure detecting locations where there is
often a large amount of trash in the ground, constant audio
blanking may be disruptive, therefore using a Threshold
Level setting of 0 (Off) is recommended unless you want to
hear audio blanking�
Reference Threshold Blanking
When a Rejected ID is detected, the threshold tone ‘blanks’
(becomes silent) to indicate that a rejected target is
underneath the coil�
If the Threshold Level is set to 0 (Off), you will not hear the
blanking of the Rejected ID's�
