TURNING ON YOUR DETECTOR
Turn the left knob (SENSITIVITY) to the right. As the knob clicks to the "On"
position, the detector sounds three beeps, the LCD arrows appear
momentarily, and the unit pre-sets to the DISC/ALL METAL mode of operation.
SET THE MODE
1. ALL METAL
A. Press the DISC/ALL METAL touchpad
B. Turn the right knob (DISC/NOTCH) to the left.
The unit will emit sound when passing over all types of metal objects.
The ALL METAL mode offers the greatest depth detection capability.
2. DISCRIMINATE
A. Press the DISC/ALL METAL touchpad
B. Slowly turn the right knob (DISC/NOTCH) clockwise.
As you turn the knob clockwise the detector will first eliminate small
iron objects such as nails. When rotated clockwise, large iron objects are
eliminated, followed by trash items such as foil and aluminum.
3. NOTCH
Press the NOTCH touchpad, and the detector will automatically reject iron.
Turn the DISC/NOTCH knob clockwise for selective elimination of various
junk items while still detecting nickels, silver and copper coins, and small
gold items. NOTCH eliminates medium tone trash items while still
detecting valuable low and high tone metals. (audio tone ID is discussed
later).
4. AUTO NOTCH
Press the AUTO NOTCH touchpad, and the detector will automatically
reject iron and most pull-tabs. Nickels and most small gold rings will be
retained. The DISC/NOTCH knob creates a rejection "window" which
can be moved as it is turned clockwise. With this mode, you can reject
screw caps and zinc (post 1982) pennies as the DISC/NOTCH control is
turned clockwise, but still detect valuables with low and high tones.
Note:
If you are not sure of your current mode setting, simply press the desired
touch-pad again.
BASIC OPERATION

IN THE FIELD TECHNIQUES
When pinpointing a target, try drawing an “X”,
as illustrated, over where the tone is induced.
PINPOINTING
Accurate pinpointing takes practice
and is best accomplished by
“X-ing” the target area.
1.
Once a buried target is indicated
by a good tone response,
continue sweeping the coil over
the target in a narrowing
side-to-side pattern.
2.
Take visual note of the place on
the ground where the “beep”
sounds.
3.
Stop the coil directly over this
spot on the ground.
4.
Now move the coil straight
forward and straight back
towards you a couple of times.
5.
Again make visual note of the
spot on the ground at which
the “beep” sounds.
6.
If needed, “X” the target at
different angles to “zero in” on
the exact spot on the ground at
which the “beep” sounds.
COIL MOVEMENT
When swinging the coil, be
careful to keep it level with the
ground about one inch from the
surface. Never swing the coil like
a pendulum.
CORRECT
WRONG
The
coil
should
be swung
in a
half-
circle
movement
as
illustrated
here.
Repeat this
motion
every step
you take to
guarantee that
the area is being
covered thoroughly.
