Expert Menu
The Expert Menu contains some of E-Trac’s
more advanced settings and functions.
While the settings and functions within the
Expert Menu will allow you to get the most
out of your E-Trac, Minelab recommends
that you become familiar with the other
settings and functions of the detector before
experimenting with these.
Recovery Deep
Range: On–Off
Factory Preset: Off
This setting affects only weak target signals,
enhancing identification of deep targets.
This setting should be selected in relatively
uncluttered areas where deep targets are
anticipated. Strong signals are unaffected.
In the deep setting there will be a slightly
slower reaction in target signal and Target ID
due to the extra filtering that is employed in
the processing of the target characteristics.
To turn Recover Deep On or Off:
1 Press the Menu button
2 Scroll across to Expert (using the Right or
Left Navigation button)
3 Scroll down to Recovery Deep (using the
Down Navigation button)
4 Press either the Left or Right Navigation
button to turn Recovery Deep On or Off
5 Press the Detect button to exit the Menu
and resume detecting
In the example shown, using Recovery Fast
will provide two distinct target IDs in each
direction, whereas when Recovery Fast is Off
the ID will be more variable and may not
resemble either of the targets.
Note: Minelab recommends turning Recovery
Fast On when Trash Density (pp. 72–3) is set to
High
To turn Recover Fast On or Off:
1 Press the Menu button
2 Scroll across to Expert (using the Right or
Left Navigation button)
3 Scroll down to Recovery Fast (using the
Down Navigation button)
4 Press either the Left or Right Navigation
button to turn Recovery Fast On or Off
5 Press the Detect button to exit the Menu
and resume detecting.
Recovery Fast
Range: On–Off
Factory Preset: Off
By selecting this setting, the detector
will react faster to target signals, but the
discrimination and Target ID may be slightly
more erratic. Use Fast in areas littered with
objects, where a desired target could be
hiding next to unwanted objects.
For example, if there are two targets very
close together that cause a single detection,
the filtering that is usually employed
when Recovery Fast is Off may cause a
‘contamination’ of the Target IDs,
as shown below.

Recovery Deep and Recovery Fast
The Recovery Deep and Recovery Fast
settings allow you to select the way the
discrimination process works. Recovery
settings affect both the detector’s audio and
display response to target characteristics.
With Recovery Fast On, the usual filtering
is bypassed and this can provide a more
accurate ID of the second target due to the
reduced blending of target signals. However,
as a consequence of removing the filtering
the Target IDs may be slightly more erratic.
