TERMS TO KNOW
The terms below are standard words found within this manual and the
detector.
DISCRIMINATION
Discriminating allows you to choose the metals you want to detect and
the ones you want to “eliminate” or not look for. Discrimination makes it
easier to avoid trash or other undesirable objects. Once it detects a metal
it will categorize it to one of the metals you chose to detect for.
IRON
Iron is the most common metal used. It has been used since ancient times
because of how abundant it is. Ferrous metals are made up of iron. Ob-
jects that are ferrous metals are; nails, bolts, stainless steel and cast iron.
PINPOINT
A narrow detection that tells you the exact location of the object that
is buried.
PULL-TABS
Also known as “pop tops.” Discarded pull-tabs come from beverage cans.
They can be all dierent shapes and sizes. They are primarily made of alu-
minum, which can be bothersome to many treasure hunters.
GROUND GRAB
All soils contain minerals. Signals from ground minerals interfere with the
signals from metal objects. If metal is detected in this mode it will make
a sound. It doesn’t detect any of earth’s natural minerals so you can get a
more accurate reading on what you nd.
TWO DIGIT IDENTIFIER
The two digit number identies the buried obect with a specic number
to give you a more accurate idea of what you have found. With each pass
over the object, the distance between the object and the coil, and the
angle of the coil can change the two digit number.

CATEGORY VALUE
The Category Value accurately provides specic categories to help identify a
buried object. Coins will most likely have a similar value with each pass with the
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 dierent value than larger gold or silver objects. Trash objects can give
o a dierent value each time you pass over it. The angle of the detector can
aect the identication of an object as well. If you decide to test the detector
by waving a coin over the coil, wave it with the at side parallel to the coil; this
position is how you will nd most buried coins.

DETECTOR MODES
Ground Grab
All soils contain minerals. Signals from ground minerals interfere with the signals from
metal objects. All soils dier, and can dier greatly, in the type and amount of ground
minerals present. This detector incorporates ground balancing algorithms which elimi-
nate interference caused by the ground minerals found in most soils. We therefore rec-
ommend that you use GROUND GRAB to most accurately calibrate the detector to the
specic ground conditions where you are hunting.
This process will maximize the detector’s target identication accuracy and depth detec-
tion capability.
The Steps is as follows:
1. Find a patch of ground which is free of metal. Use the DISCRIMINATION mode, with no targets discriminated out.
2. Hold the detector with the search coil about 6 inches above the ground ,then press G Grab button to activate ground
grab process, then lower the coil down to within 2 inches o the ground.
3. Repeat to lift up and lower down the search coil for several times until the LCD shows“GRAB OK”.
If‘GRAB ER’appears, maybe the ground is too dirty with metal trash or just wet salt soil. Find another clean place ground
grab again till it is grab ok. Ground grab results is crucial to the performance of PP mode.
Discrimination
Pick the discrimination mode you want to detect in. Keep the coil parallel to the ground
moving it from left to right with a stable speed. Out of the metals highlighted it will cat-
egorize the metal detected so you are aware of what metal is buried. It will inform you
in two ways; 1. by highlighting the metal detected and 2. a tone response.
Discrimination identication accuracy can be inuenced by moisture and temperature.
The coil sweeping speed can also aect discrimination, generally faster sweeping mo-
tion has a higher sensitivity.
Pinpointing
Pinpoint does a narrow search that will give you the exact location of a buried object. It will identify an object by a signal
and tone response. Hold the trigger to activate the pinpoint function. Once activated, sweep the coil over the target
area in an “X” pattern. Make a visual note of the place on the ground where the strongest signal is identied. Then dig
in the center of the“X.” When the trigger is released the metal detector will return back to
the previous mode. NOTE: Normally,the detector takes about 5 minutes to stabilize after it
powers on, it is not recommended to do pinpointing during this period of time. The sensi-
tivity of detector will drift over time. If sensitivity drifts upward,the detector will sound o
spontaneously. If sensitivity drifts downward,the detector will become less sensitive. Drift
is exacerbated by the environment condition change especially the temperature change.
so, in case the sensitivity drifts , you can try Ground Grab again.
Notch Modes
When in Notch there are four options:
All Metals: Use this mode if you are looking for a wide range of objects. It is designed to
nd all metal objects.
Coin: When using this mode it will show you the metals found in coins. It is designed to nd
all types of coins and eliminate trash objects such as iron and foil.
Jewelry: When in this mode it will show you the metals common in jewelry. It is designed
to nd jewelry such as rings, bracelets, watches and necklaces.
Custom: Use this mode if you want to choose the specic metals to search for . It is designed
for you to nd certain metal objects that you programmed it to.
When an object is detected it will highlight the name of the metal found as well as use a tone
that identies the metal.
GPS
The GPS mode allows you to save certain locations that you are wanting to return to later. The
farthest it will read you from your saved location is 999 yds. The closer you get to the saved spot
the lower the number will go, 000 yds means you’ve reached your spot. NOTE:While in use, please
keep the control box away from metal objects or magnetic materials because those objects aect
the accuracy of its internal compass.

HOW TO DETECT
Power ON by pushing the “POWER” button.
Use “SENS” or “ V OL” to change the Sensitivity and Volume (de-
fault is 6/4).
Use “ALL METAL”, “JEWELRY”, “COIN”, “NOTCH” or “DISCRIM”
to enter into corresponding mode.
Press the “G GRAB” button to activate Ground Grab Mode. Dis-
play will show“Grab ok”when ground grab is completed. If“Grab
ERROR” shows, there may be a metal object underground, nd
another clean area nearby to retry ground grab.
While in Discrimination/Notch Mode keep
the coil parallel to the ground moving it
from left to right with a stable speed. If it
nds something it will highlight the metal
found and give o a certain tone (refer to
page 27).
When a metal is detected hold the trigger
to activate Pinpoint function. Sweep the coil
over the target in an “X” pattern. While in Pin-
Point it will show you the depth of the metal
found. So you can accurately know how far
down to dig.
Dig object out.
Once the object is found, ll the hole back up to the way you
found it.

COURTESY
1
If you find that the compass is not so ac-
curate, or sometimes direct the wrong
way, please rotate it 3-5 circles like this:
NOTE: Keep the LCD Display horizontal.
TIPS
2
In order to get the maximum accuracy
of the compass, we suggest rotating it
3-5 times in a circle to calibrate at the be-
ginning of the GPS mode when you change
to a new environment.
3The normal function of the product may be dis- turbed by strong Electro-Magnetic Interference. If
so, simply reset the product to resume normal opera-
tion by following the instruction manual. In case the
