With your metal detector, you can hunt for coins, relics, jewelry, gold, and silver
just about anywhere. The detector is versatile and easy to use.
The detector’s features include:
LCD Display—shows the probable type of metal with an arrow, the depth of
the target, DISC/NOTCH range, the level of SENS with segment, the operating
mode, and low battery indication.
Three Tone Audio Discrimination—sounds distinctive tones for different
types of metal.
Notch—ignores junk metal and finds valuable items by setting the disc and
notch range.
Super Slow Sweep Identification—with a very slow sweep of the search coil
to discriminate different types of metal.
Headphone Jack—lets you connect headphones (not supplied) to operate in
privacy and without bothering others. Audible alerts can also be heard better.
Waterproof Search Coil— allows operation in shallow water or wet
landscapes.
Note: Your metal detector requires two 9-volt alkaline batteries (not supplied).

PREPARATION
ASSEMBLING THE DETECTOR
Assembling your detector is easy and requires no special tools. Just follow
these steps.
1. Turn the stem’s lock nut clockwise until it loosens.
2. Lengthen or shorten so when you stand upright with the detector in your
hand, the search coil is level with and about 1/2 to 2 inches above the
ground with your arm relaxed at your side.
3. Turn the stem’s lock nut counter-clockwise to lock it in place.
4. Unscrew the knob on the search coil and remove the knob connector. Insert
the stem and align the holes on the search coil bracket and the stem. Push
the connector through the holes and tighten the knob.
5. Wind the search coil cable around the stem. Leave enough slack in the
cable.
6. Insert the search coil’s plug into the search coil jack on the detector’s control
housing.
Caution:
The search coil’s plug fits into the connector only one way. Do not force
the plug or you could damage it.

8. Insert the arm support into the end of the stem and tighten the lock screw.
INSTALLING BATTERIES
Cautions:
Use only new alkaline batteries of required size.
Do not mix the old and new batteries or different types of batteries.
1.Slide the POWER button to turn off the power.
2.Slide the left and right battery covers off in the direction of the arrow.
3.Place a 9V battery into the battery compartment matching the polarity
symbols (+ and -) marked inside.
Warning:
Dispose of old batteries promptly and properly. Never bury or burn them.
Caution:
If you don’t plan to use the unit for a week or longer, remove the batteries.
Batteries can leak chemicals that could damage electronic parts.
To extend the battery life, exchange the left and right battery after
3~4hours of operation.

2. DISPLAYS
Targets are indicated by target icons and LCD displays located at the top of
the detector. It can indicate coins of different type, gold, silver etc. When the
detector detects an object, an arrow appears below the target icon of
probable type of metal being detected.Also displays the depth of the target.
If the detector receives a strong signal, the arrow appears steadily. If the
signal is weak, the arrow blinks or does not appear.
Note:
If the detecting pauses for about 5 seconds, the arrow will disappear.
If an arrow points to a coin denomination, the detector might be
detecting either a coin or another type of metal (such as jewelry, tokens,
medals, or even junk metal) about same size and type as the coin.
Since the indications are approximations, the detector might not have
actually found the item it indicates. The indicator is only a visual
reference to help you decide if an item is worth investigating.

IRON FOIL—indicates that the target is probably iron or foil. Some oxidized
iron might register somewhere within the SILVER range.
5¢(NICKEL)—indicates that the target is probably 5¢ or a nickel.
PULL TAB—indicates that the target is probably a pull tab from an
aluminium can. Some rough gold items might register within PULL TAB
category.

S-CAPS—indicates that the target is probably a type of metal like bottle cap
with whorl. Some small gold items might register within this category.
1¢—indicates that the target might be a zinc penny or a copper coin. Some
large gold items might register within 1¢ category.
SILVER Range
1¢ 25¢--indicates that the target is probably 25¢ or 1¢. Some large aluminium
coin might register within 1¢ 25¢ category.
TONES
If the detector is set to theALL METAL target mode, it sounds a single
tone when it detects any type of metal. If you set the detector to the
DISC or NORCH modes, the built in audio identification system sounds
a unique audio tone for each of three categories of metal. This makes it
easier to identify the metal being detected.
The detector sounds a low tone when it detects small gold, nail, bottle
cap or nickels. A medium tone for aluminum pull tabs, zinc or copper
items. A high tone is for brass or silver items.
Notes:
When you set the detector to DISC or NOTCH mode, the detector
sounds a medium or high tone when it detects highly oxidized iron.
An arrow appears in medium or high tone area.
Depending on the alloys used to make them, about 15 percent of
gold rings cause the detector to sound a medium tone.

OPERATION
TURNING ON THE DETECTOR
1.Slide the power switch to ON. The unit displays all symbols on the
LCD screen. The detector sounds low, medium, high tones
respectively. After about 2 seconds the detector enters stand-by state.
At this time the LCD displays ALL METAL and SENS. The value of
SENS on the segment is 5. The range from MIN. to MAX. for
DISC/NOTCH is available.
2.SETTING THE OPERATING MODE
The detector comes with three operating modes of ALL METAL, DISC,
NOTCH. You can select the desired mode by relative touch key.
a.ALL METAL—used for detecting any type of metal. When the
detector detects any type of metal, it sounds a tone.
Note: When you operate in this mode, controls of DISC and NOTCH do
not function except SENS. To adjust the sensitivity, first press SENS
and UP to increase the sensitivity, then press Dn to decrease it.
b.DISC—used for target discrimination. You can set the target range
from MAX to MIN by pressing DISC/NOTCH and UP & Dn keys. The
detector can detect the metal type indicated on the display.
Meanwhile the detector rejects other metal types without displaying
on the screen. For example, press Dn key, 4 levels on segment from
Max to Min is increased. At this time, the detector can detect S-
CAPS, 1¢ and also 25¢, other types of metal are rejected.
c.NOTCH—to ignore the metal type you do not want. You can select
the metal type desired by pressing the UP and Dn keys. The LCD
segment will indicate the selected types of metal. The detector can
detect the selected metal type.

TESTING AND USING THE DETECTOR
To learn how the detector reacts to different metals, you should test it
before you use it the first time. You can test the detector indoors and
outdoors.
Indoor Testing and Use
1. Slide POWER to ON
2. Set the operating mode.
3. Place the detector on a wooden or plastic table, and 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 with the search coil facing the floor. Most
buildings have metal of some kind in the floor, which might interfere with
the objects you’re testing or mask the signal completely.
5. Slowly sweep a sample of the material you want the detector to find
(such as a gold ring or a coin) 2-3 inches or more above the face of
the search coil. When the detector detects any metal, it sounds a
tone and an arrow appears below the target icon. Also LCD displays
the depth of the target.
Note:
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 arrow.
10

Outdoor Testing and Use
1. Slide POWER to ON. Set the operating mode.
2. Find an area on the ground outside where there is no metal.
3. 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).
4. 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.
correct
wrong
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.
11

If the detector detects the item, it sounds a tone, an arrow and the
depth appear on the display below the target icon.
If the detector does not detect the item, make sure that the target
mode is set correctly for the type of metal you’re searching for. Also
make sure that you’re moving the search coil correctly.
Notes:
The detector responds with a signal when it detects most
valuable metal objects. If a signal does not repeat after you
sweep the search coil over the target a few times, the target is
probably junk metal.
False signals can be caused by trashy ground, electrical
interference, or large irregular piece of junk metal.
False signals are usually broken or non-repeatable.
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 the
touch button SENS on the panel. Then press UP or Dn to increase
or decrease the sensitivity. The level on the segment will be
displayed from high to low position.
Note:
In order to detect the target deeply buried, you can adjust the SENS
to a high position. 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 arrow and irregular tone indications.

Application Hints
Pinpointing The Target
Accurately pinpointing a target makes digging it up easier. But it takes
practice. We suggest you practice finding sample on your own property
before you search other locations.
Follow these steps to pinpoint a target.
1. When the detector detects a buried target, continue sweeping the
search coil over the target in a narrowing side-to-side motion.
2. Make a visual note of exact spot on the ground where the detector
beeps.
3. Stop the search coil directly over this point on the ground. Then move
the search coil straight forward away from you and straight back
towards you a couple of times.
4. Repeat steps 1~3 at a right angle to the original search line, Make a
mark of “X”. The target will be directly below the “X” at the point of the
beep response.
Factors That Affect Detection
It’s difficult to have an accurate detecting result. Sometimes the
detecting may be restricted by some factors.
13

1.Conditions For The Target Being Detected
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.
If you detect patiently and correctly and practise more times, you’ll
get satisfactory result.
CARE AND MAINTENANCE
Your QP-2307 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.
