①VOLUME/POWER switch
Rotate volume control away from OFF to power on the detector.
②LCD DISPLAY
③CONTROL BUTTONS
MENU: Press MENU, LCD will display LIGHT, SENS, DISC,
NOTCH. One of the displayed item will flash. If no button is
pressed in about 5 seconds, the flashing item will be selected.

NOTCH: Eliminates the target you don’t want. Press MENU to
select NOTCH.Then press+or–to select the target to be notched.
The cursor above the selected target will flash.PressNOTCHagain,
the target name below the cursor will disappear.
PP: Pinpoints the location of the target accurately.
LIGHT: Press MENU to select LIGHT. Then press + or – to adjust
the level (0-9 ) of LIGHT. The level will be displayed on the LCD.
Note: As the backlight consumes more power, it’s better to turn off
it in light places.
④MEMORY
The detector will memorize all the settings before power is off.
4.TESTING AND USING THE DETECTOR
A.INDOOR TESTING AND USE
1.Rotate the volume control away from OFF to power on the detector.
2.Follow the instructions described in OPERATION to set the
SENSITIVITY,VOLUME,DISC,NOTCH and operation 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.
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 coin over search coil might cause false indication and
unstable display of target.

B.OUTDOOR TESTING AND USE
1. Rotate the volume switch away from OFF to power on the detector.
2. Follow the instructions described in OPERATION to set the
SENSITIVITY,VOLUME,DISC,NOTCH and operation mode.
3. Find an area on the ground outside where there is no metal.
4. 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).
5. 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 motion.
Search coil Sweeping Hints:
Never sweep the search coil as if it were a pendulum. Raising the
search coil while sweeping or at the end of a sweep will cause
false readings.
Sweep slowly, hurrying will cause you to miss targets.
It’s better you sweep the search coil from side to side in an arc
line of 3 inches motion and keep the search coil parallel with the
ground.

5.TARGET INDICATIONS
1. Numeric ranges of target:
-IRON: 00-10
-5¢: 11-20
-P-TAB: 21-40
-ZN(1¢): 41-60
-10¢: 61-75
-25¢: 76-99
Note: There are a wide variety of metals and no target can be tified for
certain until unearthed. This table is for general reference only.
2.
Types of target
- IRON: It indicates that the target is probably iron.
- 5¢:It indicates that the target is probably 5¢ or a nickel. Some
small gold rings might register within this range.
- P-TAB: It indicates that the target is probably a pull tab of an
aluminum can. Some small gold rings might register within this
range.
- 1¢: It is indicated that the target is probably a coin of 1¢ or type
of metal of zinc alloy. Some medium sized gold rings might
register within this category.
- 10¢: It indicates that the target might be a coin of 10¢. Some
large rough gold items might register within this category.
- 25¢: It indicates that the target is probably 25¢ or a silver coin.
3.
Tones
The detector comes with three tones for different types of metal.
A low tone is for IRON, 5¢, same as for foil, bottle cap or nickels. A
medium tone is for P-TAB, ZN, 1¢(aluminum pull tabs, zinc or copper
items). A high tone is for 25¢,same as for brass or silver items.
If the detector detects the item, it sounds a tone, and the cursor above
the target name will light. Also LCD displays the numeric range of
target as well as the depth(signal strength).

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 MENU to select SENS. Then press + or - to increase or
decrease the sensitivity. The level will be displayed on the LCD.
Note:
In order to detect the target deeply buried, you can adjust the SENS to
a high level. But not to set the level of SENS to Max. position, or the
detector will receive interference and false signal from broadcast
antenna and other electronic lines. The detector will have unstable and
irregular indications.
Using LIGHT
In dark area, you can use LIGHT for better searching. Press MENU to
select LIGHT. Then press + or – to adjust the level (0-9 ) of LIGHT.
The level will be displayed on the LCD.
Note: As the light consumes more power, we suggest you setting the
value to 0 in normal environment.
6.Factors That Affect The Detecting
It’s difficult to have an accurate detecting result. Sometimes the
detecting may be restricted by some factors:
 The angle of the target buried in the soil.
 The depth of the target.
 The level of oxidization of the target.
 The size of the target.
 Electro-magnetic and electrical interference surrounding the
target.

1.Sensitivity set too
high/environmental
electromagnectic
interference
2.Sweeping the detector's
search coil too fast or at
wrong angle.
3.Using 2 detectors in
close proximity
1.Reduce sensitivity.
2.Sweep the search
coil more slowly and
hold the detector in
the proper position
3.Keep any two
detectors at least 6
meters(20'') apart.
The detector
does not detect
anything.
1.Sensitivity set too low.
2.Target range is
eliminated.
3.Search coil is not
parallel
with the ground
1.Increase sensitivity.
2.Recover all target
range.
3.Ajust the search coil
angle to be paralle
with the ground

1.There may be more
than one kind of metal
in the target items.
2.The detector can't
identify the target.
Sometimes,oxidized
metal also causes the
proble.
1.Reduce the
sensitivity to
eliminate
the detection of the
deeper target.
2.Sweep the search
coil with different
angels.
The detector
does not work
1. Five-pin cable not
connected well.
2. Dead battery
1.Re-plug it properly.
2.Replace batteries.

7.CARE AND MAINTENANCE
Your metal detector is an example of superior design and
craftsmanship. The following suggestions will help you care for your
metal detector so you can enjoy it for years.
Handle the detector gently and carefully. Dropping it can
damage circuit boards and cases and can cause the
detector to work improperly.
Use the detector only in normal temperature environments.
Temperature extremes can shorten the life of electronic
devices, damage the cases of the detector.
Wipe the detector with a damp cloth occasionally to keep It
looking new. Do not use harsh chemicals, cleaning
solvents, or strong detergents to clean the detector.
Keep the detector away from dust and dirt, which can cause
premature wear of parts.
