Sat (Self-Adjusting Thresold); Vco (Voltage Controlled Oscillator) - White's MX Sport User Manual

To add the Salt Track feature to any program:
1. Press Options and use the up & down arrows to select Salt
Track.
2. Use the + & - buttons to select either 1 for salt ground bal-
ance range or 0 for normal ground balance range.
Often soft sand will gather more saltwater compared to the sur-
rounding sand. Because these spots have a sharp increase in
conductivity, the MX Sport will likely beep regardless of whether
metal is present. If a reasonable beep is produced that doesn't
pinpoint sharply like a typical metal object (pinpoints as a large
area with a lower than normal volume beep), it is likely a salt
pocket; ignore and continue searching.
Additionally, when searching at the wave line, one may hear the
incoming and outgoing waves respond to some degree. It is best
to search fully in the water or fully on the beach. In most cases
natural sluicing (wave action gathering all heavy metals in one
streak or patch) occurs either in the water or on the beach. In
other words, natural sluicing often leaves targets behind the
waves (on the beach), or takes it out into the water. With a tide
guide and patience, you can search 100% of the beach.
You may want to turn Salt OFF (0 in the Beach mode) when
searching fresh water beaches (no salt). The extended ground
balance range provided by the salt feature is not recommended
when searching areas that do not have wet salt (conductive
ground conditions). Only when conductive ground conditions are
present will the salt feature improve performance.
ALL METAL PROGRAM-ONLY FEATURES
SAT (Self-Adjusting Threshold)
SAT only influences the All Metal, Relic, and Prospecting pro-
grams and only appears in Options when one of these programs
is activated.
SAT makes the All Metal programs require motion to detect
metals. Stopping over any metal for any significant length of time
24
will reset the audio to natural, and that metal target will stop re-
sponding. Again, when using SAT, search coil sweep is required.
When searching in an All Metal program, searching with a
threshold hum is mandatory for maximum detection depth. In
an All Metal mode (without SAT) the threshold hum will fade or
increase with time as well as any slight change in the ground.
Although these slight changes in conditions can be heard in
the changing threshold hum, they are not significant enough
to dictate any operator change in settings. SAT automatically
maintains the threshold hum over time and irregular conditions
by resetting the threshold at regular (timed) intervals. These
timed intervals can be sped up or slowed to match how quickly
the ground conditions are changing and how quickly you want to
sweep the search coil.
To adjust SAT when All Metal, Relic, or Prospecting programs
are in use:
Press Options and use the arrows to select SAT. Use the + & - to
select levels 0 = no SAT to 6 = Hyper SAT. Use the SAT speed
nearest "0" that maintains a steady continuous threshold hum.
Quicker SAT speed settings, near to 6 (Hyper SAT), require
quicker search coil sweep speeds due to the fact that fast SAT
can tune out metal target responses if swept too slowly.
Select the slowest (lowest number) SAT speed that maintains
a steady threshold and no faster. Match the speed the search
coil is swept to the SAT speed. Practice with a target above the
ground to assure the search coil is being swept briskly enough to
respond to targets.

VCO (Voltage Controlled Oscillator)

VCO only influences the All Metal, Relic, Prospecting, and Pinpoint
programs, thus only appears in Options when one of these pro-
grams is activated. For the Pinpoint mode, lock in Pinpoint, then
press options and select VCO.
VCO provides an increase in the pitch of the beep as the search
coil nears a metal target. As the search coil moves away from
a metal target the pitch of the beep decreases. In this way the
center of the metal target is obviously the highest-pitched beep.
