Range Slow, Medium, Fast
Tracking Speed
Keeping up with Changing Ground
(Ground Balance, pg. 40)
Tracking Ground Balance is the preferred setting
when searching in highly variable mineralisation.
Tracking Ground Balance automatically adjusts the
Ground Balance, as necessary, to maintain stability
and detection depth. The speed of the Tracking
can be changed to suit the degree of variable
mineralisation.
The GPX-4500 has three Auto Tracking Speed
options: Slow, Medium & Fast.
The preferred Tracking Speed is the slowest speed
which keeps up with the variability of the ground
mineralisation. You should gradually increase from
Slow Tracking Speed, Medium Tracking Speed, then
Fast Tracking Speed as required.
Slow
The Slow Tracking Speed is recommended if seeking
out large, deep targets in variable ground, but you
should check your ground balance often and re-
balance (pg. 41) whenever necessary.

Fixed
Medium
In ground conditions which make operating in Fixed
impractical, the factory preset Medium setting
provides a good compromise between effectively
maintaining the Ground Balance and pausing the
Ground Balance when a target is located.
Fast
The Fast Tracking Speed is very effective at adjusting
the Ground Balance in highly variable soils. Its use
will only be required in extreme cases.
Coils with Tracking
When using a Monoloop coil the nature of the
Tracking tends to be more aggressive. Faint,
deep targets may be 'tracked out'. In extreme,
highly variable, soil types you may achieve better
performance by opting to use a Double D coil
instead of a Monoloop, and then selecting the most
appropriate Tracking Speed.
Initial Very Fast Ground Balance
Every time you switch from Fixed to Tracking on the
front control panel, or via the Quick-Trak button,
the GPX-4500 will initiate a very fast auto Ground
Balance. The Tracking Speed does not affect the
speed of the initial very fast auto Ground Balance.
