To change the Response:
1 Press the Menu button
2 Scroll across to Audio (using the Right or
Left Navigation button)
3 Scroll down to Response (using the Down
Navigation button)
4 Press either the Left or Right Navigation
button to change the Response to the
desired setting
5 Press the Detect button to exit the Menu
and resume detecting
Note: Even though you can still select Pitch
Hold when the No. of Tones is set to 1,
it will not have any effect on the target
audio response.
Smooth
This setting is similar to Long, with the addition of
some filtering of the audio tone response. Smooth
reduces the variability of the pitch, offering a
smoother continuous sound.
Pitch Hold
When Pitch Hold is selected, the normal rise-and-
fall target signal is replaced with a continuous tonal
response. The tone emitted is the strongest signal
coming from the target, and will continue until a new
target is detected.
Response
Range: Normal, Long,
Smooth and Pitch Hold
Factory Preset: Normal
The Response setting changes the way target
signals sound upon detection. Response can
improve your ability to identify certain targets
in different conditions, such as high trash,
mineralised ground and beaches.
As the coil is swept over a target, the target
signal rises. At the peak of the target signal,
audio is emitted. Minelab recommends first
learning how to operate the detector in the
Factory Preset ‘Normal’ audio Response.
After becoming familiar with the way E-Trac
interprets various targets, it is recommended
you experiment with the Response settings
listed right. Each Response will suit certain
detecting conditions. You will soon develop
your own preference by experimentation.
Normal
Emits a short response to targets (almost a ‘beep’).
Normal is recommended for general detecting
conditions. It allows the greatest differentiation
between the ground and a target, but has the
potential to miss small targets in areas littered with
objects producing target responses.
Long
Offers an almost continuous audio response. This
setting is ideal for responding to several targets close
together. It is recommended for the experienced user,
who can pick the tonal differences between various
targets. Long can be a little confusing for the
beginner but has the potential to offer greater
accuracy and depth.

Blanking
Normal lasts until the target signal drops, then audio
blanks bringing a crisp end to the detection.
Pitch Hold changes the Threshold to the highest
pitched tone produced during the detection.
Long lasts until the end of detection.
There is no blanking at the end of detection.
Smooth lasts until the end of detection.
