Introducing the Detection Screens Pattern Screen
The E-Trac comes pre-programmed with
three unique Detection Screens. The selection
of the appropriate Detection Screen for
the current conditions will depend on your
preferences and experience. The three
Detection Screens are:
– Pattern
– Digital
– QuickMask
All the information required for detecting
targets is contained within these three
Detection Screens, and when combined
with audible target responses, no buried
treasure is safe.
When the detector is turned on for the first
time, the Pattern Screen will be displayed
on the LCD and E-Trac is ready to begin
detecting. Target information is presented to
you via the Smartfind Discrimination Pattern,
Sensitivity Gauge, FE-CO numbers and Depth
Gauge. The information available to you in
the Pattern Screen is invaluable for successful
detecting with E-Trac.
Information is refreshed in ‘real time’; enabling
fast, clear and reliable interpretation of a
potential target’s qualities. With practice and
experience you will be better able to interpret
the information displayed, leading to more
successful detecting.
The Smartfind Window is in the centre of
the Pattern Screen. It displays the active
Discrimination Pattern (p. 21). Above the
Smartfind Window is the area in which
an accepted target’s FE-CO numbers will
appear. During and after a detection, a
Target Crosshair will appear in the Smartfind
Window, displaying the target’s FE-CO
coordinates relative to the rest of the
Discrimination Pattern. The FE-CO numbers
and Target Crosshair will remain until a new
‘accepted’ target is detected. Display Timeout
(p. 79), in the Preferences Menu, can be
turned on and this will clear detection results
after a five seconds.
The Depth Gauge is located to the right of
the Discrimination Pattern.
The Sensitivity Gauge is to the left, and by
default it is turned on. The Sensitivity Gauge
can be turned off via the Preferences
Menu (p. 78).
The Detect button on the Control Panel
switches between the Pattern and Digital
Screens, and returns you to these Screens if
you are in the Main Menu, QuickMask or Edit
Screen. In addition, the QuickMask button
provides a shortcut between the QuickMask
Screen and the Pattern/Digital Screens (see
diagram below).
The last Detection Screen used will appear
the next time you turn on the detector. Any
adjustments to Discrimination Patterns made
in the Pattern Screen will be retained and
used in Digital as well.
Ferrous-Conductivity
Numbers
The area where FE-CO
numbers of an accepted
target are displayed.
Discrimination Pattern
(Accepted)
The white (clear) area of
the Disc. Pattern is the
target FE-CO numbers
that you have accepted.
Discrimination Pattern
(Rejected)
The black area of the
Disc. Pattern is the target
FE-CO numbers that you
have rejected.
– This dialogue box (p. 37) will appear, allowing you to confirm whether or not you wish to
load the QuickMask Discrimination Pattern into either the Pattern or Digital Screen.
Auto Sensitivity Gauge
The left bar, and the
number at the top, is
the user-set Sensitivity.
The right bar is the
‘suggested’ Sensitivity.
Depth Gauge
Represents the
approximate depth of
a target beneath the
coil. The range, from top
to bottom, is 0–30cm
(0–12”).
