Thank you for choosing our Metal Detector TX-910. Please read this manual
carefully and know the function of TX-910 before use. And please keep it for
future reference.
It is recommended to use the TX-910 outdoors, because there is too much
interference indoors.
In the higher sensitivity range, the detector will be more sensitive to
electromagnetic interference. By reducing the sensitivity, the interference
will be reduced correspondingly.
When detecting metals, move the search coil at a constant speed. Keep the
search coil parallel with the ground and about 1/2 inch above the surface.
Do not swing it like a pendulum.
For coin-sized objects, the depth indicator is accurate. But for large-sized
objects or irregular-shaped objects, the accuracy will reduce slightly.
For most of the valuable metal objects, the detector will send out a consistent
signal. If the signal isn't consistent, it may be a false signal.
The LCD panel will automatically darken every 10 minutes. Hold the Vol
（Backlight）key for 2 seconds to light it up.
If the PINPOINT mode malfunctioned, sending a signal even though there
is no metal, lift the detector and press the P-P key once to solve the prob-
lem.

1. Turn On
2. Set the Operation Mode
3. Choose the Sensitivity
Take a 25￠ silver coin and move it closer to the search coil slowly. At the
position of about 7" to 8", the first set of the signal strength cursor begins to
appear, the sound becomes louder and the tone becomes higher. If you
continue to move the 25￠ silver coin, the signal strength cursor changes to
the full grid in a second, and it sounds louder. Meanwhile, the depth indicator
indicates the depth decreases correspondingly to have only one grid left,
showing that the metal is gradually approaching the center of the search
coil (See Fig. 16).
TX-910 is designed for outdoor use. There are too many objects indoors and all
kinds of electrical equipment that will cause interference. It is not suitable to
use the detector indoors.
Field detection will be more complicated. Because there are so many elements
that will affect the detection results, such as the composition of the regional
soil, the component, size, shape and the oxidation degree of the underground
metals. The following content is only the general steps for field detection. You
should operate the detector again and again to accumulate your experience to
achieve good results.
Hold the detector, and keep the search coil away from the ground. By pressing
the Power button, the detector will sound two tones, and all the LCD lights up
for a while. And the detector is restored to the setting of the last shutdown.
In general, the user could choose the ALL METAL mode. In this mode, the
detector will respond to all kinds of metals.
The user tends to set the sensitivity higher. However, in the higher sensitivity
range, the detector will be more sensitive to the electromagnetic interference
that comes from the power lines or cables around, and it will react abnormally
to the mineralized soil or soil with electrical conductivity. If you move the search
coil in the detection area, and the detector sends an unstable false signal,
please decrease the sensitivity.
If you operate the detector with your partner at the same time, please pay attention
to keep more than 393.7 inches away from each other, and decrease the sensitivity
appropriately.
b)
Press the P-P key again to exit the PINPOINT mode and the P-P icon will be
removed.
By following all the steps above, you will have a basic knowledge of the
detector, and you can move on to the next part of the basic operation.

4. Move the Search Coil
7. Depth Indicator
5. Make Use of the Sound to Help Discrimination
6. Make Use of Double Digits to Help Discrimination
When detecting, move the search coil at a constant speed, rather than sweep it
unsteadily. Keep the search coil parallel with and about 1/2 inch above the
surface. Do not swing it like a pendulum (See Fig. 17).
The following table is used as a preliminary guide. The approximate ranges of
the US dollar and pound coins are listed in the table.
When detecting, the double digits may be different slightly, depending on the
composition, size, shape, distance from the search coil and the speed of
detecting. The surrounding soil also affects the value. There are differences in
casting coins in different years. There is a wide range for gold, a thin ring is
about 45, and a rough ring and gold coin may reach up to 70-80. The table
below is just for reference.
For coin-sized objects, the depth indicator is accurate. But for large-sized or
irregular-shaped objects, the depth readings will be less accurate. If you sweep
the search coil at the same place several times, and it shows the same depth,
then the detection result is accurate. If the depth indicator varies, try to change
the angle of sweeping. There may be more than one target present.
Most valuable metal objects will send repeatable signals. If the signal isn’t
repeatable, it’s mostly a false signal. When there is a clear sound for buried
targets, you could find out the approximate target type and depth on the LCD
screen. And you could also move the search coil above the target objects fast
to get a more stable signal.
When detecting, you don’t need to stare at the screen all the time. And the
sound identification system will sound three frequency tones to help discriminate
the target metals.
Low Pitch-- 5￠nickel coin and so on;
Medium Pitch-- pull-tab, soda bottle and zinc coin;
High Pitch-- copper, aluminum and silver metal, such as 1￠, 10￠, 25￠and
so on.
