Tracking Speed
Keeping up with changing ground.
Tracking Ground Balance is the preferred setting when
searching in highly variable mineralisation. Tracking Ground
Balance automatically measures the ground mineralisation
and 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 5000 and GPX 4800 have 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 (p. 41)
whenever necessary.
Note: If you are detecting in highly variable ground, a
slower sweep speed will give Tracking more time to
re-ground balance.
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
Tracking tends to be more aggressive when using a Monoloop
coil. Faint, deep targets may be ‘tracked out’. In extreme, highly
variable soil types you may achieve better performance by
using a Double D coil instead of a Monoloop, and then select
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 Series will
initiate a very fast auto Ground Balance. The Tracking Speed
does not affect the speed of the initial very fast auto
Ground Balance.
