Soil/Timings
You can select which timings will be activated by the Special
switch on the control panel.
Sensitive Smooth
(GPX 5000)
Sensitive Smooth is optimised for an improved response on
smaller, shallow nuggets in heavily mineralised soils. There is
a slight loss of depth on bigger targets; so you should not use
this setting when seeking out large, deep nuggets.
Sensitive Smooth allows the use of monoloop coils in highly
mineralised areas. It eliminates most false signals from hot
rocks, and ground mineralisation, whilst retaining excellent
sensitivity to small targets.
Fine Gold (GPX 5000)
Fine is highly sensitive to smaller targets in mineralised
ground. It provides a sharper signal on small gold compared to
Enhance, and improves the detectability of rough/flaky gold
and specimens, whilst ignoring most hot rocks signals and
false ground noises. Shallow, highly mineralised ground where
gold has been found previously should be re-examined with
Fine Gold, and best results will be had by using the optional 8”
and 11” Commander Monoloop coils.
Sensitive Extra
This timing may increase the signal from certain hot rocks near
the surface, but can actually help smooth out the Threshold in
certain ground types; particularly with Double D coils. In mild
ground conditions Sensitive Extra will provide the best signal
response on a small, deep target.
Salt/Gold (GPX 5000)
Salt/Gold is designed for use in mineralised soils that have a
high salt content. It should work well on dry inland salt lakes,
high salt concentrated goldfields, and mineralised saltwater
beaches. Extremely salt saturated soils may still need to be
searched with the coil switch in Cancel (using a Double D coil).
