TARGET INFORMATION
Target ID Legend
The Target ID Legend functions with the Target ID Cursor to indicate the
probable metal type of the target, with ferrous ( iron ) targets at the left,
non-ferrous targets which are thin or have low conductivity in the middle,
and thick or high conductivity targets at the right.
Horizontal Scale
The horizontal scale shows the present discrimination pattern, with lighted
pixels indicating accepted targets and blank pixels indicating rejected
targets.
Target ID Cursor
When the detector detects a target, a Target ID Cursor will display for this
target if the metal signal is strong enough; but the detector will produce
audible signal only for targets accepted on the horizontal scale and will
probably not produce audible signal for objects rejected on the horizontal
scale.

- 12 -
Digital Target ID
Provides a two-digits number to identify target more precisely than the
Target ID Cursor. Target ID can vary widely based on the target's size and
thickness because small, thin pieces of metal can not conduct electric
current as well as thicker pieces of metal. Moreover, mineralized soils can
cause Target ID errors, especially for small targets.
Note:
Soil mineralization reaction can be eliminated most efficiently when the
target is centered under the search coil and the search coil is swept flat
and at a constant height above the ground. After the detector detects a
target, you can perform detection on this target several times and discard
wrong Target ID readings obtained and take only correct Target ID readings.
The smaller the indicated depth of burial, the stronger the detected metal
signal, and the more reliable the Target ID reading.
Category Value
When the detected metal signal is strong enough, a target ID cursor will
appear in a certain position to indicate the probable metal type ( or
category ) of the detected metallic object. According to the position of the
target ID cursor, you can predict the probable metal type ( or category ) of
the detected object by referring to Figure 8 and the Target ID Legend ( see
Figure 7 ) above the target ID cursor. Figure 8 is essentially similar to the
Target ID Legend but the information contained in Figure

- 13 -
8 is expressed using words and is far more detailed than the information
contained on the Target ID Legend. You can use Figure 8 in conjunction
with the target ID cursor like you use the Target ID Legend.
Coins will most likely have a similar value with each pass with the search
coil due to their round shape. Gold and silver can actually be detected in
various category values due to their metallic qualities. Smaller gold or
silver objects will have a value different from that of a larger gold or silver
object. Trash objects can give off a different value each time the search coil
passes over it. The angle of the detector can also affect the identification of
an object. If you decide to test the detector by passing a coin across the
search coil, pass it with its flat side parallel to the search coil; this position
is how you will find most buried coins.
Figure 9 shows an example display shown when the metal detector detects
a US 25-cent coin buried about 15cm below ground surface.

DETECTING METALLIC OBJECTS
DETECTING METALLIC OBJECTS IN THE ALL METALS MODE
The All Metals Mode allows the detector to achieve the maximum detection
depth possible.
Press the ON/OFF button to turn on the metal detector. To select the All
Metals Mode, press the "ALL-METAL/DISC" button until the symbol "ALL
METALS" appears on the display.
1. Adjust the Sensitivity
Hold the detector by its handle. Lift and adjust the search coil so that the
search coil is about 50cm above and parallel to the ground. The detector
sensitivity is adjusted via the "SENSITIVITY/MODE SELECTION" button,
and the number of the displayed sensitivity indicator bars graphically
indicates the present sensitivity. Press the " + " or " - " side of the
"SENSITIVITY/MODE SELECTION" button until a faint sound from the
detector is heard.
2. Perform Ground Balance Adjustment
To cancel out the minerals in the soil, you must perform ground balance
adjustment before you start scanning in the All Metals Mode in a site.
Use the following procedure to perform ground balance adjustment:
1. Hold the detector and move it to a place where there is no metallic
object in the ground under the search coil.
2. Lift and adjust the search coil so that the search coil is about 50cm
above and parallel to the ground.
3. Press the " + " or " - " side of the "GROUND BALANCE/CUSTOM
SELECTION" button once. The symbol "GROUND BALANCE" appears on
the display, and the ground balance setting ( which is in the range of -99 to
+99 ) is shown on the display.

- 15 -
4. Lower the search coil to approximately 5cm to 8cm above ground. If the
sound from the detector increases when the search coil is lowered to
ground, raise the search coil to about 50cm above ground, and then press
the " - " side of the "GROUND BALANCE/CUSTOM SELECTION" button
to decrease the ground balance setting. If the sound from the detector
decreases when the search coil is lowered to ground, raise the search coil
to about 50cm above ground, and then press the " + " side of the
"GROUND BALANCE/CUSTOM SELECTION" button to increase the
ground balance setting.
Tip: Pressing and holding down the " + " or " - " side of the "GROUND
BALANCE/CUSTOM SELECTION" button will increase or decrease the
ground balance setting quickly.
5. Repeat step 4 until the sound from the detector remains approximately
unchanged when you lower and lift the search coil. Now the ground
balance adjustment is completed.
3. Begin Scanning
After you have completed the sensitivity adjustment and then the ground
balance adjustment, you can start to scan for metallic object or target.
During scanning, keep the search coil height approximately 5cm to 10cm
above and parallel to the ground at all times for best detection results, walk
slowly as you scan slowly the search coil in a straight line from side to side.

- 16 -
When the detector detects a metallic object, a target ID cursor will appear
in a
certain position to indicate the probable metal type of the object being
detected and a digital target ID, which is a two-digits number, will be shown
on the display if the strength of the detected metal signal exceeds the
detector's identification threshold, and at the same time, and if the target is
accepted by a lighted pixel on the horizontal scale, the sound from the
detector will increase.
Because many factors ( degree of oxidation of metallic object, metal
impurities in soil, soil moisture content, size and metal content of the object,
depth, etc ) can affect the target ID cursor indication and digital target ID,
the target ID cursor indication and digital target ID are not accurate and are
only for non-critical reference. The target ID cursor indication and digital
target ID are not guaranteed to be correct.
When the detected metal signal is strong enough, the display will show a
target depth indicator bar, which is to be used in conjunction with the depth
scale for you to predict the distance between the detected object and the
search coil. Because many factors can affect the indication of target depth
indicator bar, the indication of the target depth indicator bar is not accurate
and is not guaranteed to be correct. It is only for non-critical reference.
During scanning, the search coil must be in motion. If the search coil is still,
the detector can not detect metal normally.
4. Pinpoint a Detected Metallic Object
After you detect a metallic object, you can use the Pinpoint function to
pinpoint this object. Precisely pinpointing a object allows you to quickly
recover the ground because of smallest digging hole possible.

- 17 -
Use the following procedure to pinpoint a target:
1. Move the search coil around the detected metallic object to determine
the
approximate location of this object. Then move the search coil to this
location, and then hold the search coil in this location and above the
detected object.
2. Press and hold down the PINPOINT button. The display shows the
symbol "PINPOINT" and all the 8 sensitivity indicator bars.
3. Release the PINPOINT button and then immediately ( within 1 sec after
the release of the button ) hold down the button gain. The number of the
displayed sensitivity indicator bars decreases by 1, and the sound volume
of the detector decreases accordingly.
4. Move the search coil a little distance toward the metal signal source
( the detected object ) according to the volume of the sound. The sound
volume of the detector increases as the search coil approaches the metal
signal source ( the detected object ).
5. Repeat step 3 and 4 to approach the target progressively. And in the
end, the target can be pinpointed.
Note:
The detector exits the PINPOINT mode automatically about 3 secs later
after you release the PINPOINT button.
DETECTING METALLIC OBJECTS IN A DISCRIMINATION MODE
If you want to detect a specific type ( or kind ) of metallic objects while
largely ignoring other types of metallic objects during scanning, you should
select a suitable Discrimination Mode. There are 5 Discrimination Modes in
total, they are JEWELRY mode, COINS mode, DEBRIS mode,
ORNAMENTS mode, and CUSTOM mode. You can select any of these
modes to meet your need.

- 18 -
The detector has 12 pixels or "notches" of discrimination, shown on the
horizontal scale ( see Figures 2 and 7 ). In any Discrimination Mode, the
detected target which is accepted by a lighted pixel on the horizontal scale
will cause an increase in sound, and the targets which are rejected by a
blank pixel on the horizontal
scale will probably not cause an increase in sound.
Among these modes, the JEWELRY mode, COINS mode, DEBRIS mode,
ORNAMENTS mode are preset and can not be modified, but in CUSTOM
mode, you can modify the present discrimination pattern freely to create a
desired discrimination pattern to better meet your need.
To select a desired Discrimination Mode, first make sure that the detector is
in a Discrimination Mode. If the detector is in the All Metals Mode ( "ALL
METALS" is display ), press the "ALL-METAL/DISC" button until the
symbol "DISCRIMINATE" appears on the display. Then press the " + " or " -
" side of the "SENSITIVITY/MODE SELECTION" to select among the 5
Discrimination Modes.
Whenever a mode is selected, the display will show the corresponding
mode indicator ( see Figure 2 ) to indicate the presently selected mode.
The five Discrimination Modes are explained as follows:
•JEWELRY Mode
Designed to find jewelry such as rings, watches, bracelets, and necklaces,
while ignoring most iron trash.
•COINS Mode
The COINS mode is designed to find US coins and similar coins and
eliminate common trash items such as iron and foil. Be aware that
medium-sized jewelry may be missed with this discrimination pattern and
that some junk targets ( such as aluminum cans ) may be detected and
cause an increase in sound.
•DEBRIS Mode

- 19 -
The DEBRIS mode is designed to detect debris while eliminating
( ignoring ) small iron pieces.
•ORNAMENTS Mode
The ORNAMENTS mode is designed to detect most kinds of metallic
ornaments.
•CUSTOM Mode
The detector has 12 pixels or " notches " of discrimination, shown on the
horizontal scale. The CUSTOM mode allows you to modifiy the present
discrimination pattern freely and create a desired discrimination pattern. To
do it, first make sure that the detector is in the CUSTOM mode and that the
search coil is far away from any metallic object and inference source. Then
press the " + " or " - " side of the "GROUND BALANCE/CUSTOM
SELECTION" button to move the Target ID Cursor to the right or left until it
is in the desired position. And then press the " PINPOINT " button to
eliminate or activate the pixel located on the horizontal scale, directly
below the Target ID Cursor. ( See Figures 11 and 12. )
