varied from 0 to 99 with the UP and DOWN arrow
buttons. A 0 discrimination setting will allow all metals
to activate the high tone; a 99 discrimination setting
fully discriminates out most iron targets, allowing only
nonferrous objects (like gold) to activate the high
tone (this two-tone audio system will be explained
shortly). When prospecting, you will choose an
optimal discrimination setting between 0 and 99 that
allows you to ignore most of the iron trash in your
hunting area, without giving up any good targets.
Also notice that the constant control readout shows
you approximate settings at all times with a graphical
icon, whether you are in the MENU mode or the
search mode.
arrow buttons between –99 (high threshold) and +4
(low threshold). There are a couple of considerations
in choosing a threshold setting: (1) If you prefer to
have an audio threshold tone present while hunting,
choose a setting between 0 and +4. This will allow
your Gold Strike to react to the tiniest targets in a
low mineralization environment. (2) However, if you
plan to utilize the fast automatic ground tracking
feature of the Gold Strike, set the threshold to a –5
or –10 setting for stable tracking performance (and
even lower in harshly mineralized soils).
of 0 to a maximum of 10 with the arrow buttons when
the SENS icon is flashing. As with most detectors, set
the sensitivity higher for best depth performance in
soils that are low in mineralization.
mineralization gets worse, lower the sensitivity setting
as needed. We recommend a sensitivity setting of
5 or lower for the most stable performance if the fast
automatic ground tracking is enabled. Please note
that a SENS setting of 0 or 1 will still yield excellent
results.
