Features
With your metal detector, you can hunt for coins, relics, jewelry, gold, and silver
just about anywhere. The detector is versatile and easy to use.
The detector’s features include:
LCD Display—shows the probable type of metal with an arrow, the depth of
the target, DISC/NOTCH range, the level of sensitivity, the operating mode, and
low battery indication.
Three Tone Audio Discrimination—sounds distinctive tones for different
types of metals.
Notch—ignores junk metal and finds valuable items by setting the disc and
notch range.
Super Slow Sweep Identification—with a very slow sweep of the search coil
to discriminate different types of metal.
Headphone Jack—lets you connect headphones (not supplied) and operate
without trouble.
Waterproof Search coil—lets you use the detector even if you must put it
under water.
Note: Your metal detector requires two 9-volt alkaline batteries (not supplied).

PREPARATION
ASSEMBLING THE DETECTOR
Assembling your detector is easy and requires no special tools. Just follow
these steps.
1. Turn the stem’s lock nut clockwise until it loosens.
2. Lengthen or shorten stem so that when you stand upright with the detector in
your hand, the search coil is level with and about 1/2 to 2 inches above the
ground with your arm relaxed at your side.
3. Turn the stem’s lock nut counter-clockwise to lock it in place.
4. Unscrew the knob on the search coil and remove the knob connector. Insert
the stem and align the holes on the search coil bracket and the stem. Push
the connector through the holes and tighten the knob.
5. Wind the search coil cable around the stem. Leave enough slack in the
cable.
6. Insert the search coil’s plug into the search coil jack on the detector’s control
housing.
Caution:
zThe search coil’s plug fits into the connector only one-way. Do not force
the plug or you could damage it.

desired angle so that it is parallel with the ground. Then tighten the knob.
Caution:
Do not over-tighten the search coil or use tools such as pliers to tighten it.
8. Insert the arm support into the end of the stem and tighten the lock screw.
INSTALLING THE BATTERIES
Cautions:
zUse only fresh alkaline batteries of required size.
zDo not mix the old and new batteries or different types of batteries.
1.Slide the POWER button to turn on the power.
2.Slide the left battery cover off in the direction of the arrow.
3.Place a 9V battery into the battery compartment matching the polarity
symbols (+ and -) marked inside.
Warning:
zDispose of old batteries promptly and properly. Never bury or burn them.
Caution:
zIf you don’t plan to use the unit for a week or more at a time, remove the
batteries. Batteries can leak chemicals that can destroy electronic parts.
zTo extend the battery life, exchange the left and right battery after
3~4hours of operation.
USING HEADPHONES
1.Insert the headphones’ 3.5mm plug into the HEADPHONE jack. At this
5

time the internal speaker disconnects.
2.Set the VOLUME to the desired setting.

Listening Safely
zTo protect your hearing, set the volume to the lowest setting before you
begin listening, adjust the volume to a comfortable level.
zDo not listen at extremely high volume levels. Extended high volume
listening can lead to permanent hearing loss.
zDo not wear headphones while operating your detector near high-traffic
areas. Pay attention to traffic safety.

2. DISPLAYS
The target indicator includes target icons and LCD displays and is located at
the top of the detector. It can indicate different types of coins, gold, silver, etc.
When the detector detects an object, an arrow appears below the target icon
of the probable type of metal being detected and also displays the depth of
the target. If the detector receives a strong signal, the arrow appears steadily.
If the signal is weak, the arrow blinks or does not appear.
Note:
zIf the detecting pauses for about 5 seconds, the arrow will disappear.
zIf an arrow points to a coin denomination, the detector might be
detecting either a coin or another type of metal (such as jewelry, tokens,
medals, or even junk metal) about the same size and type as the coin.
zSince the indications are approximations, the detector might not have
actually found the item it indicates. The indicator is only a visual
reference to help you decide if an item is worth investigating.

GOLD Range
IRON FOIL—indicates that the target is probably iron or foil. Some oxidized
iron might register somewhere within the SILVER range.
5¢(NICKEL)—indicates that the target is probably a nickel.
PULL TAB—indicates that the target is probably a pull-tab from an aluminum
can. Some rough gold items might register within the PULL TAB category.
S-CAPS—indicates that the target is probably a type of metal like a bottle cap
with whorl. Some small gold items might register within this category.
1¢—indicates that the target might be a zinc penny or a copper coin. Some
large gold items might register within 1¢ category.
SILVER Range
1¢ 25¢--indicates that the target is probably 25¢ or 1¢. Some large aluminum
cans might register within the 1¢ 25¢ category.
TONES
If the detector is set to the ALL METAL target mode, it sounds a single
tone when it detects any type of metal. If you set the detector to the
DISC or NOTCH modes, the built in audio identification system sounds
a unique audio tone for each of three categories of metal. This makes it
easier to identify the metal being detected. The detector sounds a low
tone when it detects small gold items, nails, bottle caps or nickels, a
medium tone for aluminum pull-tabs, zinc or copper items, and a high
8

tone for brass or silver items.
Note:
zWhen you set the detector to DISC or NOTCH mode, the detector
sounds a medium or high tone when it detects highly oxidized iron.
An arrow appears in medium or high tone area.
zDepending on the alloys used to make them, about 15 percent of
gold rings cause the detector to sound a medium tone.

OPERATION
TURNING ON THE DETECTOR
Slide the power switch to ON. The unit displays all symbols on the
LCD screen. The detector sounds low, medium, and high tones,
respectively. After about 2 seconds the detector enters stand-by state.
At this time the LCD displays ALL METAL and SENS. The value of
SENS on the segment is 5. The range from MIN. to MAX. for
DISC/NOTCH is available.
SETTING THE OPERATING MODE
The detector comes with three operating modes of ALL METAL, DISC,
and NOTCH. You can select the desired mode by the relative touch
key.
ALL METAL—used for detecting any type of metal. When the detector
detects any type of metal, it sounds a tone.

Note: When you operate in this mode, only SENS. control will function,
DISC. Or NOTCH controls will not. To adjust the sensitivity, first press
SENS and UP to increase the sensitivity, then press Dn to decrease it.
a.DISC—used for target discrimination. You can set the target range
from MAX to MIN by pressing DISC/NOTCH and UP & Dn keys. The
detector can detect the metal type indicated on the display.
Meanwhile the detector rejects other metal types by not displaying
them on the screen. For example, press Dn key, 4 levels on segment
from Max to Min and discrimination is increased. At this time, the
detector can detect S- CAPS, 1¢ and also 25¢, while other types of
metal are rejected.
b.NOTCH—to ignore the metal type you do not want. You can select
the metal type desired by pressing the UP and Dn keys. The LCD
segment will indicate the selected types of metal. The detector can
detect the selected metal type.
TESTING AND USING THE DETECTOR
To learn how the detector reacts to different metals, you should test it
before you use it the first time. You can test the detector indoors and
outdoors.
Indoor Testing and Use
1. Slide POWER to ON
2. Set the operating mode.
3. Place the detector on a wooden or plastic table, then remove any
watches, rings, or metal jewelry you are wearing.
4. Adjust the search coil so the flat part points towards the ceiling.
Note:
Never test the detector on a floor inside a building. Most buildings have

metal of some kind in the floor, which might interfere with the objects
you’re testing or mask the signal completely.
5. Slowly sweep a sample of the material you want the detector to find
(such as a gold ring or a coin) 2-3 inches or more above the face of
the search coil. When the detector detects any metal, it sounds a
tone and an arrow appears below the target icon. Also the LCD
displays the depth of the target.
Note:
If you are using a coin, the detector will detect it more easily if you hold
it so a flat side is parallel with the flat side of the search coil. A sweep
with the side of a coin over the search coil might cause false indication
and an unstable display of the arrow.
Outdoor Testing and Use
1. Slide POWER to ON. Set the operating mode.
2. Find an area on the ground outside where there is no metal.
3. Place a sample of the material you want the detector to find (such
as a gold ring or a coin) on the ground.
Note:
If you are using valuable metal such as gold to test the detector, mark
the area where you place the item, to help you find it later. (Do not place
it in tall grass or weeds).
4. Hold the search coil level to the ground about 1~2 inches above the
surface, slowly move the search coil over the area where you
placed the sample, sweeping the search coil in a side-to-side
11

motion.
Search coil Sweeping Hints
zNever sweep the search coil as if it were a pendulum. Raising the
search coil while sweeping will cause false readings.
zcorrect
wrong
zSweep slowly. Hurrying will cause you to miss targets.
zSweep the search coil from side to side in an arc line of 3 inches of
motion and keep the search coil parallel with the ground.
If the detector detects the item, it sounds a tone and an arrow and
the depth appear on the display below the target icon.
If the detector does not detect the item, make sure that the target
mode is set correctly for the type of metal you’re searching for. Also
make sure that you’re moving the search coil correctly.
Note:
zThe detector responds with a signal when it detects most
valuable metal objects. If a signal does not repeat after you
12

13
sweep the search coil over the target a few times, the target is
probably junk metal.
zFalse signals can be caused by trash-filled ground, electrical
interference, or large irregular pieces of junk metal.
zFalse signals are usually broken or non-repeatable.
Adjusting SENSITIVITY
After you become familiar with how your detector works, it’s
important to fine-tune the sensitivity to get a good effect. Press the
touch button SENS on the panel. Then press UP or Dn to increase
or decrease the sensitivity. The level on the segment will be
displayed from high to low position.
Note:
In order to detect a target deeply buried, you can adjust the SENS
to a high position. But do not set the level of SENS to Max position,
or the detector will receive interference and false signal from
broadcast antennas and other electronic lines. The detector will also
have unstable arrow indications and irregular tone indications.
Application Hints
Pinpointing The Target
Accurately pinpointing a target makes digging it up easier. But it takes
practice. We suggest you practice finding samples on your own
property before you search other locations. Follow these steps to
pinpoint a target.
1. When the detector detects a buried target, continue sweeping the
search coil over the target in a narrowing side-to-side motion.
2. Make a visual note of the exact spot on the ground where the
detector beeps.

3. Stop the search coil directly over this point on the ground. Then move
the search coil straight forward (away from you) and straight back
(towards you) a couple of times.
4. Repeat steps 1~3 at a right angle to the original search line, Make a
mark of “X” . The target will be directly below the “X” at the point of
the beep response.
Factors That Affect The Detecting
It’s difficult to have an accurate detecting result. Sometimes the
detecting may be restricted by some factors:
1.Conditions For The Target Being Detected
zThe angle of the target buried in the soil.
zThe depth of the target.
zThe level of oxidization of the target.
zThe Size of the target.
zElectro-magnetic and electrical interference surrounding the
target.
If you detect patiently and correctly and practice these techniques,
you’ll get satisfactory result.
