Thank you for choosing our Metal Detector TX-650. Please read this manual
carefully and know the function of TX-650 before use. And please keep it for
future reference.
It is recommended to use the TX-650 outdoors, because of too much
interference indoors.
In the higher sensitivity range, the detector will be more sensitive to elec-
tromagnetic 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 consis-
tent signal. If the signal isn't consistent, it may be a false signal.
If the PINPOINT mode malfunctioned, sending a signal even though there
is no metal, lift the detector and press the P-P button once to solve the
problem.

Basic Operation
1. Target Information
Power Button—Press to power the detector on or off.
Battery Indicator—Show the remaining battery power. Replace batteries in
time when there is only one bar left.
Target Metal Value—Work with the Target Metal Cursor to indicate the target
metal, with ferrous (iron) targets at the left, non-ferrous targets that are thin or
with low conductivity in the middle, and thick or targets with high conductivi-
ty (e.g., thick silver) at the right.
Target Metal Cursor (Upper Line)—All the cursors will be displayed once
powered on, but it will only make sounds for targets selected on the lower
line.
Discriminated Metal Cursor (Lower Line)—Display the current discrimina-
tion pattern, with displayed cursors indicating selected targets and blank
cursors indicating discriminated targets.
Double Digits/P-P—Display a value from 0 to 99 to identify targets more
precisely than the metal cursor.
Coin Depth Indicator—Show the depth of a coin, or a target of a similar size.
Note: Targets larger than a coin may display shallower than actual depth
while targets smaller than a coin may display deeper than actual depth.
The following sample chart displays the ranges of some commonly found
items.
The values can vary widely based upon the target's size and thickness, as
small, thin pieces of metal cannot conduct electrical current like thicker
pieces of metal. In addition, in mineralized soils, errors may appear in some
values, especially for small targets.
Note: The double-digit is most reliable when the target is below the center of
the search coil and the coil is swept flat and at a constant height above the
ground when detecting.

3. Selecting Modes (Discrimination Patterns)
4. Sensitivity
Tone ID—The Metal detector produces three distinct tones based on a
target’s metal type and conductivity.
Note: This is the preset notch discrimination pattern for the COINS mode.
Choose one from five preset discrimination patterns or use the CUSTOM mode
to save a personal pattern.
JEWELRY Mode—Designed to find jewelry such as rings, bracelets, watch-
es, and necklaces, while ignoring most iron trash.
CUSTOM Mode—It can be programmed by the user and the metal detec-
tor will save the changes when the detector is switched off. The factory
preset for the CUSTOM mode is the same as the COINS mode. Beginning
with this discrimination pattern, press DISCRIM and Enter buttons to
customize the mode as desired.
RELICS Mode—Designed to eliminate small iron pieces, while detecting
valuable targets within the range of the lower conductivity, such as lead,
brass and bronze.
COINS Mode—Designed to find most types of coins and to eliminate
common trash items such as iron and foil. Some desired items similar to
foil may also be eliminated. The detector may respond to some buried junk
targets, such as aluminum cans.
NON IRON Mode—Designed to find valuable targets, such as brass, silver
and gold, and eliminate all kinds of iron trash.
Use the (↑) or (↓) SENSITIVITY buttons to increase or decrease the sensitiv-
ity of the detector, with eight (8) levels. Increase the sensitivity when search-
ing targets that are too small or buried deeply below the earth. Decrease the
sensitivity when the detector is working erratically (due to excessive metallic
trash, highly mineralized soils, electrical interference or the presence of other
metal detectors). Under this situation, the erratic operation cannot be
resolved with discrimination.
· A/M‒Detect every type of metal. All 12 cursors are displayed with no metals
discriminated. Use this mode to find all metal items or when the material of the
desired object is unknown. Switch to the A/M mode to help in locating a target.
When its signal is inconsistent, it may mean that a trash target is close to a good
target.
Headphone Jack—Use any headphones with a plug of 3.5mm.
Targets with high conductivity (the value is larger than 60) produce a
unique bell-tone signal.
Targets with medium to low conductivity (the value is between 40 and 60)
produce a medium-pitched signal.
Ferrous targets (the value is less than 40) produce a low-pitch signal.
Use the MODE buttons to select the six modes. Sensitivity Indicator

5. Notch Discrimination Pattern
6. PINPOINT
Notch Discrimination—Use the (↑) or (↓) DISCRIM buttons with the
ENTER button to eliminate trash objects from detection such as foil or
pull-tabs.
The metal detector has 12 cursors or "notches" of discrimination, shown on
the lower line. Any cursors can be switched on or off as desired. There are two
primary methods for modifying the Notch Discrimination pattern to eliminate
a specific type of trash or unwanted item.
For the first method, use the (↑) or (↓) DISCRIM buttons to select the target
metal cursor on the left or right. Next, press the ENTER button to eliminate or
select the cursor on the lower line, directly below the line of the target metal
cursor.
The second method of modifying the Notch Discrimination pattern is to press
the ENTER button only. When an unwanted target is detected, simply press
the ENTER button to eliminate the target metal cursor. The next time when
this item is encountered, the detector will not make a response to it.
Note: Notch Discrimination can also be used to find specific metal items. For
example, if you lost an earring, scan the other earring with the A/M mode
selected and note its target metal cursor. Then use the DISCRIM and ENTER
buttons to switch off all the cursors on two lines except the one for the earring
to detect and find out the earring.
Press the (↑) or (↓) DISCRIM buttons to position the target metal cursor on
the upper line above the one you want to eliminate (see the figure above).
Press the ENTER button to eliminate this cursor from the lower line (see the
figure below). And this item is now eliminated, which means the detector will
not respond to it.
Note: Changes made to the Notch Discrimination pattern when the detector
is in the CUSTOM mode will be saved when the detector is switched off.
Changes made to all other modes will not be saved, which means it will
return to the factory settings every time when the detector is switched off.
In this mode, it can help to find the target metal much faster.
Sweep the search coil around the suspected location at a constant height
above the ground.
Press the PINPOINT button and slowly sweep the search coil above the
target area while keeping at the same height above the ground (e.g.
0.78-1.18 inches).
Sweep the search coil side-to-side and front-to-back like a cross to locate
the position with the strongest signal, that is, the loudest sound and the
greatest number of segments on the upper line.

7. Bench Tests 8. Hunting Tips of the Metal Detector
The center of the search coil is directly above the target with the depth of a
coin-sized target shown on the depth indicator. The symbol "P-P" for
PINPOINT displays on the LCD screen while the detector is operated with
the PINPOINT mode.
You should conduct bench tests to become more familiar with the operation
of the detector. Please follow the steps below.
Place the search coil on a flat, non-metallic surface that is several feet
above other metallic objects.
Select the A/M mode.
Place various metal objects (coins, bottle caps, nails, etc.) below the
search coil with a distance of 3.14 to 3.93 inches. The detector will make
responses and you can identify the targets with the LCD screen.
Perform this test in all the modes available on the detector. Listen to the
sounds and observe the changes on the LCD screen to be more familiar
with the operation of the detector.
Record the results of your bench tests and refer to them when hunting in
fields.
Upper Line: Indicate
the signal strength
P-P/PINPOINT Button:
Press to use the PINPOINT mode
Coin Depth Indicator Once you get familiar with the detector and know how it responses to metals
during bench tests, do more tests in the soil. Bury your targets at recorded
depths to create a "test pilot." Note how various targets read based upon
whether they are lying in the ground, flat or at various angles.
Keep accurate records or surface markers for your test pilot to indicate
targets and their depths. Try testing these targets again in several months
after the ground has settled, during periods of extreme drought or after a
soaking rain. Take notes of any changes in how these targets are detected.
If you never detect metal targets before, start searching in areas with sandy
and loose soil to make it easier to learn how to use the metal detector,
pinpoint and dig targets.
Keep the search coil at the height of about 0.78-1.18 inches above the
ground and parallel to the ground at all times for best detection results.

- 15 -- 14 -
Sweep the search coil and keep it parallel to the ground and the surface of
the water, which will minimize the negative effects caused by the uneven
ground and varying amounts of moisture near the water. Do not sweep the
search coil perpendicular, as this may produce abrupt changes in ground
response that may reduce the detector's performance.
2.23 mph 2.23 mph
0.78-1.18 inches
To fully search an area, overlap the sweeping of your search coil by half the
length of the coil (about 5.51 inches). Sweep the search coil in a straight
line or with a slight arc at a sweeping speed of about 2.23 mph.
Four bars indicate that batteries are fully charged. Replace batteries when
there is only 1 bar remaining. The detector will still perform well until the
batteries need to be replaced. It can be expected to work for 20 to 40 hours
depending on the type and quality of batteries.
Remove all batteries when the metal detector will be stored and not be used
for longer than 30 days.
Walk slowly as you sweep the search coil in the straight line from side to
side at a speed of about 2.23 mph. Stretch the search coil forward about
half the length of the search coil when finishing detection.

The metal detector is durable and designed for outdoor use. However, as with
all electronic equipment, there are some simple ways you can care for your
detector to maintain its best performance.
Used products with batteries should be taken to a recycling station and not be
disposed of with household waste. Hand it over to the applicable collection
station for the recycling of electrical and electronic equipment. The separate
collection and recycling of the product will help to conserve natural resources
and ensure that it is recycled in a manner that protects human health and the
environment. Disposal must be carried out in accordance with local environ-
mental regulations for waste disposal. For more details about where you can
drop off the appliance for recycling, please contact your local city office, your
household waste disposal service or the seller from whom you purchased the
product.
Avoid using or storing it in extreme temperatures, such as storing the detec-
tor in an automobile trunk in summer or outdoors in sub-freezing weather.
Keep the detector clean. Wipe the stem, control box, and search coil with a
damp cloth when necessary.
Please note that the search coil is waterproof and submersible, but other
parts of the detector are not.
When storing the detector for longer than one month, remove the batteries
from the detector.
When replacing batteries, use quality AA batteries, and use all new batteries
for optimum performance.

Intermittent Signals
Solutions
1. Ensure batteries are installed correctly.
2. Replace all old batteries with new batteries.
1. If using the detector indoors, be aware that
excessive amounts of electrical interference may
exist, as there are excessive amounts of metal
indoors and on walls.
2. Check if you are close to other metal detectors
or other metal structures, such as electrical power
lines, wire fences, etc.
3. Decrease the sensitivity.
Intermittent signals typically mean that you've
found a deeply buried target or one that is posi-
tioned at a difficult angle for your detector to
read. Scan it from different directions to define
the signal. In the case of multiple targets, switch
to the A/M mode or press the PINPOINT button
to precisely locate all targets.
Ensure that you are using the correct mode for
the type of metal you are detecting. If specifically
hunting for coins, COINS mode is the best choice
to eliminate other undesirable targets. You can
also use the A/M mode, which detects all metal
targets to ensure that desired targets are present.
If the target metal cursors flash erratically, you
may have found a trash target. However, a target
metal cursor may flash if a valuable target (such
as a coin) is not parallel to the search coil (e.g., on
edge). It may also flash if there is one or multiple
"junk" targets next to the valuable target. Scan it
from different directions until the target metal
cursor becomes more stable.
