*DUAL CONTROL DISC “P” Preset.
While
operating in the Coin & Jewelry MODE The
DUAL CONTROL functions as a traditional dis-
crimination control. Further clockwise settings
provide greater degrees of trash metal rejec-
tion. Counterclockwise settings provide lesser
degrees of trash metal rejection. Settings much
higher (further clockwise) than the “triangle” will
reject aluminum, however, will also reject nickels
and many items of gold jewelry. It is best to use
settings near the ‘triangle” (highest setting that
still responds to a USA nickel or medium gold
ring) and rely upon the display and depth read-
ing to sort out lightweight aluminum. Lightweight
aluminum typically indicates with shallow depth

“Music Notes” Tone ID.
Coin & Jewelry always
starts out with Tone ID ON. Targets higher on the
VDI number scale respond with progressively
higher pitch tones. At minimum discrimination
(fully counter clockwise) seven different audio
tones represent the entire target range from iron
the lowest pitch, to large silver coins the high-
est pitch. Audible tones are depending upon the
Discrimination setting; rejected targets audio
is suppressed so not all seven tones may be
heard. As the discrimination control is advanced,
lower pitch tones (starting with iron the low-
est) are suppressed (eliminated). Press “music
notes” Tone ID once to turn OFF Tone ID (all
accepted targets produce the same pitch tone),
press again to turn ON Tone ID.
*Trigger (on handgrip);
Trigger Center Position “Primary Searching”
(Relic Type DISC control).
With the Trigger on
the handgrip in the center position, the DISC
control works like most high-end Relic metal
detectors in that ALL metal items respond. Met-
als rejected by the DISC control setting produce
a low pitch tone; metal items accepted by the
DISC control setting produce a higher pitch tone.
Trigger Squeezed and held “Pinpoint-
ing/Depth Reading”
. When operating in the
Relic MODE and the Trigger on the handgrip is
squeezed and held, the audio is changed to an
all-metal (no trash rejection) pinpoint mode and
the display provides a screen that indicates the
depth and intensity of coin sized targets to fur-
ther aid in pinpointing exactly where to dig. Once
released the trigger will automatically return to
the Center “Primary Search” position.
