2.SENS (Sensitivity): Adjust the sensitivity from 1 to 10. The higher the
number, the more sensitive the detector. This sensitivity control does
not affect Pinpoint sensitivity.
If the detector beeps erratically or beeps when there are no metal
objects being detected, reduce the sensitivity.
Note: Cell phones, cell phone towers, etc... all produce interference signals
and will cause the detector to beep when no metal is present, and
sometimes to beep erratically.
3.VOLUME :Adjust the volume level from 0 to 10.
4.DISC: Discrimination is an important feature of professional metal
detectors. It allows user to ignore trash and unwanted objects.
The DISC control is Discrimination function of the detector. In its default
setting, all metals are detected. Use this DISC function in order to
eliminate unwanted types of metals from detection. You only need to
eliminate the targets in order.Each time you press "+" button, a
target will disappear. The target disappears means that category is
eliminated from detection. To pick up the eliminated target category,
press "-" and categories will be accepted back in order.
Notice:The two targets on the right cannot be eliminated.
two targets represent silver or other high value targets, which are
generally desirable. So the detector does not allow them to be
discriminated out.
5.NOTCH: It is similar to Discrimination（DISC）.It allows you out
of turn to accept or reject different types of metals . The DISC
can only accept or reject metals in order.
The NOTCH Mode is only applicable in FOIL, 5¢, ALUM, and 1¢
these four categories.
Press "+" or "-" to a new category. The target ID will flash for 3
seconds and then it will change to the opposite state. Or press
MENU while the target ID is flashing,and then it will change to
the opposite state. If the target had been illuminated previously
and disappears now indicates that the target has been
eliminated from detection. As same, the target disappeared
before and illuminates now indicates that target is notched in
or can be detected.

TESTIGN THE DETECTOR
1.Supplies Needed:
• A bottle cap (made of iron) • A quarter (25¢)
• A nickel(5¢)
• A Gold Ring
2.Position the Detector:
① Place the detector on a table with the search coil hanging
over the edge.
② Be sure that the search coil is far away from walls or
metal objects. Keep the search coil away from any metal
in the table.
③ Turn off equipment that may interfere with electromagnetic
radiation.
④ Pivot the search coil back.
⑤ Press POWER to turn on.
3.Using ALL METAL Feature：
Wave all objects over the search coil and notice the different
tones.
4.Using DISC (Discrimination) Feature:
① Press MENU until DISC is displayed on LCD.
② Press "+" once. The bottle cap(iron) indicator will disappear.
③ Wave the bottle cap. It will not be detected because it has
been "discriminated out."
5.Using NOTCH Feature:
①Press MENU until NOTCH is displayed on LCD.
② Press "+" twice， 5¢ will flash for 3 seconds and disappear
that means 5¢ is "notch out" (eliminated). To eliminate 1¢,
press"+" until 1¢ flash and disappear.
③ Wave 5¢ or 1¢ over the search coil. 5¢ and 1¢ will not be
detected because they have been "notched out"(eliminated).
Notice: the target categories disappear on LCD can not be
detected.
If you want to pick up the target type you eliminated before,
press "+" or " - " to the target, and then wait for the target to
flash for 3 seconds, or press MEMU button when it is flashing.
6.Using PINPOINT Feature:
① Press and hold "PINPOINT" button, PP will appear on LCD
display.
② Hold a coin motionless over the search coil.
③ Sweeping coin over search coil.
④ Notice that the sound changes as the coin moves closer or
further.
⑤ Notice that the depth indicator changes as the coin moves
up and down.
7.Adjusting SENS(Sensitivity)
① Press MENU until SENS is displayed on LCD.
② Press "+" or "-" to set the SEN. Sensitivity level can be set from
1 to 10.
8.Adjusting VOLUME
① Press MENU until VOLUME is displayed on LCD.
② Press "+" or "-" to set Volume. Volume level can be set from 0
to 10.
OVERLOAD WARNING
If a metal object or highly magnetic soil are too close to the
search coil, the detector will overload and "- - " will appear on LCD
display. The detector will make a rapid, repeating mid-tone warning
sound. Overload will not harm the detector, but the detector will not
function in these conditions. If overload occurs, keep the search coil
away from the target.
Note: There is a wide variety of metals and no target can be
identified for certain until unearthed. This table is for general
reference only.
OUTDOOR DETECTING
1.Find a place outside where there is no metal.
2.Place a sample you want to find on the ground.
3.Press POWER to turn on the detector.
4.Swing the search coil gently from side to side, slightly overlapping
each sweep as you move forward. Keep your search coil approximately
1-2 inches above the ground as you search.
3 ft/soc
Notes:
• Raising it during the sweep ,or at the ends of your sweep, can cause
false readings.
• Move slowly; hurrying will cause you to miss targets.
• Most desirable objects will respond with a repeatable tone. When
discriminating, iron and foil objects generally do not respond.
• False signals can be caused by trashy ground, electrical
interference, or by large irregular trash objects. These signals
are easily recognized by their often broken or non-repeatable
nature.
DETECTING WITH PINPOINT
After you find a target, you can use PP(Pinpoint) to find the exact
location of the target as follows.
1.Press and hold PP to activate the Pinpoint feature.
2.Move the search coil slowly across the target, and you can locate
it by the sound.
Narrow the Detection Rage:
1.To narrow the response further, position the search coil near the
the target.
2.Press PP button and hold, move the search coil slowly.
3.When you hear the sound, you can release the PP.
4.And then press PP to continue the detection. In this way, you can
narrow the range of the target.
5.Repeat the above steps.
When the coil moves to the center of the target，the signal from the
detector is the strongest.
