DUAL CONTROL
DISC -DISCRIMINATION (outer ring)
When in COIN & JEWELRY and RELIC MODE
VARIABLE SELF ADJUSTING THRESHOLD SPEED (SAT)
When in Prospecting MODE.
While operating in the Coin & Jewelry or Relic
MODEs the Dual control operates as a DISC (dis-
crimination ) control.
DISC (Discrimination) is used to adjust the level of
audio rejection against trash metals.
The "P" (Preset) just below NICKEL is recom-
mended for most general purpose searching. In this
position, the detector will provide a reject response
to most iron and light foil and respond to most valu-
ables including jewelry.
Positions lower than "P" (counterclockwise)
provide less trash metal rejection, to the point of
detecting virtually all types of common metals.
Positions higher than “P” (clockwise) will reject
more trash metals including aluminum pull tabs.
The display will continue to indicate I.D. even
though the audio discriminator will signal with a
reject (suppressed or broken) sound. Nickels and
some jewelry will also be rejected with DISC set-
tings much greater than "P".
The "P" position is recommended for most
MODES. If when searching at the "P" position you
feel you are digging too much trash, adjust DISC
slightly clockwise and try again. Finding the lowest
(furthest counterclockwise) position that eliminates
the common trash metals in your area is important
in order to fi nd items of jewelry.
The MXT 300 provides six signifi cantly different
DISC (Discrimination) modes.
1. Traditional DISC mode is available;
A. In the Coin & Jewelry MODE with the
Trigger on the hand grip in the center
position
B. And in the Relic MODE with the Trigger
in the forward position (with the DISC
control set for typical trash rejection).
