GMX Controls
Ground Controls
Gold is usually found in min-
eralized ground, and the GMX
has XGB enabled by default
when the machine is powered on.
This makes it easy to get started
prospecting, as the machine au-
tomatically cancels out unwanted
mineralization so you can focus on
listening for targets.
However, there are times when
you may want the option to LOCK
the ground balance control, or even
display the ground information on
screen. The comprehensive ground
options on the GMX allow you to
do both of these things quickly and
easily, without menu-diving.
XGB
The original Goldmaster® featured a revolutionary ground filter system that was quick
to respond to mineralization changes. But even this industry standard had its limitations.
XGB is the automatic ground tracking method used by the GMX, and features an all-new
method and algorithm thanks to modern processing speeds and updated Digital Signal
Processing. For users this means that they can use this detector in a wider variety of
ground conditions with more stable operation and less ground noise. When coupled with
the Iron Cancel and SAT settings you have a truly versatile set of tools to combat nasty
ground.
XGB is the default setting on the GMX, and recommended for most users in most condi-
tions. It has the ability to track a wide range of ground, from ferrous to alkali, and features
an increased tracking speed over previous models without hurting sensitivity to small
nuggets. The arrows above and below the LOCK icon indicate whether XGB is tracking
up or down in values.
The algorithms used in XGB also give the GMX an edge due to the ability to track mul-
tiple ground points simultaneously. In highly variable grounds this is a huge benefit, as
you may encounter wide enough swings in ground phase to render other machines almost
unusable.
Even though XGB is the suggested ground setting, advanced prospectors know that there
are times when more control over the ground settings can equal more gold in your pouch.
Details on these settings follow.
