Minelab E-Trac Manual

Preferences Menu
The Preference Menu allows you to change the appearance of E-Trac’s detection screens by using installed
option settings like, Contrast, Pinpoint, Display Timeout and Show Sensitivity – these new features are
explained in more detail here.
Pin Point Modes (2)
The Factory Preset is: Normal
E-Trac oers its owners two distinctly separate Pin Point settings – in one or the other setting the
information coming back via your speaker or headphones can be quite telling giving lots of valuable
information prior to putting a spade to the turf at all.
In Normal it operates just the same as any other VCO type pin point system giving a precise audible
location and rising to a crescendo screech when the center of the coil or best detection area is directly
over the center of the target – this also ensures correct and ‘true value’ target ID’s
The rst sweeps over a target will give a wide response. Subsequent passes will set the ‘baseline’ (strength
of audio output) of the audio response to a new level, just below the maximum signal – the “in-ground”
Sensitivity is also adjusted – these ‘adjustments’ keep the response narrow but, will allow targets at
dierent depths to be pinpointed with equal precision. Say goodbye to scratched coins and hello to
previously dicult to trace deep targets!
In Sizing the ‘baseline’ is set to the original level the moment that Pinpoint is activated. From then on, the
baseline and the sensitivity are held at constant levels.
Sweeping over a target in Pinpoint Sizing, the detector produces a linear audio tone – the pitch of the tone
is proportional to the strength of the target response, and the volume is proportional to the position of the
target under the coil.
During use with Normal pinpoint ..say you have just detected a ‘large sounding’ target, it can at times
be a stubborn process to glean the ‘rough’ target dimensions and target shape back from the ground
with repeated passes over the target. With Sizing this is a thing of the past! Press Menu, scroll to the
Preferences Menu, scroll down two slots and engage Pinpoint Sizing and with the coil away from the
target engage pinpoint and come back in slowly and evenly over the target. You will be delighted to nd
that not only can you distinguish a shape you will also be able to tell in the case of elongated objects
where a target begins and ends allowing you a guesstimate at what the target might be? This can assist in
cleaner and safer target recoveries.
Show Sensitivity: The Factory Preset is: On
This setting, either On or O lets you select whether or not you want the Sensitivity Gauge (2 bars) on your
detect screen. This is a very useful innovative new feature. There may be times when you might decide to
not have it displayed - if switched O, Sensitivity has then to be accessed via the Menu button – if On, it
can be adjusted via the Navigation Buttons (described above)
Show Mode Info: The Factory Preset is: O
This allows you to turn the Mode Information Icons, of which there are four, On or O – these icons are
located at the very top of E-Trac’s control box display.
Display Timeout: The Factory Preset is: O
When the Display Timeout is On, the last on-screen detection results (FE & CO readout, Target Crosshair
& Depth Gauge) will be cleared from the screen after 5 seconds. When the Display Timeout is O, the last
detection result will remain until a new detection is made or, the Detection Screen is changed.
