SAFETY OPERATION MAINTENANCESETUP
Functions and Indicators
On/Off/Volume - Turns on power to the
unit and sets the sound level.
SENS - Sets the sensitivity level of the unit. Zero
setting is the lowest level and 10 is the highest.
For general use, set the sensitivity to a higher
position. In a mineralized area, or area with electrical
interference, a lower setting may be more effective.
MODE - Sets the unit to three modes:
DISC, ALL METAL and TONE.
Target Button - It is used with ALL METAL
mode to pinpoint a target object’s location.
DISC/TONE - Adjustment knob for metal identification.
View Meter - Registers signal strength
when a metal is detected.
- DISC, ALL METAL, and TONE are motion modes. You
have to move the Search Coil to find your target object.
- Target Mode is for pinpointing the location of
the item when the item is below the surface. Figure 3
Before Getting Started
Before beginning an outside search, you must test
the unit with samples of metal. Use the following:
• an iron nail
• a five-cent coin (nickel)
• a one-cent penny (zinc coin, after 1982)
• a 25-cent silver quarter.
Place the Metal Detector on a wooden or plastic table
with the Search Coil face up. Make sure the table is
away from TVs, computers, or any device that can
cause electromagnetic interference. See Figure 4.
Figure 4
NOTE: Be sure to remove any watches, rings, or
other metal objects on your fingers and hands.
Turn on the Metal Detector and set the VOLUME
dial to the middle position. Set the MODE switch
to the middle (ALL METAL). See Figure 5.
Figure 5
Sweep the metal samples 2 to 3 inches or more
above the center of the Search Coil. The Metal
Detector will respond to each with a “DI” tone and
the pointer on the View Meter will swing to the right.
NOTE: Be sure to move the samples, as
the Detector is in motion mode. Otherwise
the Detector will not respond.
NOTE: Adjusting the SENS dial from “0” to
“10” will increase the Detector’s sensitivity.
Use the DISC/TONE dial to search for
specific metals by having it not detect
(“differentiate”) other kinds of metals.

SAFETYOPERATIONMAINTENANCE SETUP
For example, when the DISC/TONE dial is set to “0”
the Detector will respond to ANY metal object with
a “DI” tone and the meter will swing to the right.
1. To adjust the settings to PREVENT the
unit from detecting iron metals, set the
VOLUME and SENS dials at midpoint.
2. Then set MODE switch to DISC and the DISC/
TONE dial to about “9 o’clock.” See Figure 7.
Figure 7
3. As a test, sweep the iron nail sample 2 to 3
inches above the search coil. The unit will NOT
respond (the meter pointer won’t swing and the
unit is silent.) Sweeping the other samples should
produce the “DI” tone and make the pointer move.
4. To have the unit differentiate nickel metals, set
the DISC/TONE to about “11 o’clock.” See Figure
8. Sweep the nickel in front of the Search Coil;
the unit will not respond to the nickel or to the
iron nail. But it will respond the other samples.
Figure 8
5. To prevent the zinc penny from being
detected, set the DISC/TONE dial to
about “1 o’clock” See Figure 9.
Figure 9
By now, only the silver quarter should be detected.
NOTE: The discrimination position of aluminum is
similar to silver. So both metals will be detected at
the same time. The discrimination position of gold is
similar to the nickel setting.
The Metal Detector can also be adjusted
to detect all metals, yet signal a specific
metal differently from the others.
6. Set the MODE switch to TONE and the VOLUME
and SENS dials to their halfway points.
7. Set the DISC/TONE dial to about “9 o’clock” (the
iron setting). Sweep the nail 2-3 inches above the
Search Coil. The unit will make a short “KO” sound
and the meter will swing to the right. Sweeping any
of the other samples will produce the “DI” sound.
8. Rotate the DISC/TONE dial to mark the other
specific metals with the “KO” sound.
To use the Metal Detector to “target’ specific
metals, set the MODE switch to ALL METAL and
the VOLUME and SENS dials to the middle.
9. Press the red TARGET Button (6) on the panel.
Set the silver quarter about five inches from
the center of the Search Coil. The unit will
make a continuous long tone and the meter
will swing to the right. See Figure 10.

10. Keeping the coin still, release the TARGET button.
Wait two seconds, then press down the TARGET
button again; the unit’s sensitivity will be reduced.
11. NOTE: Even though the coin’s location has not
changed, when the unit’s sensitivity is reduced
the Metal Detector will stop sounding a tone.
12. Repeat the above operation, bringing the
coin closer to the Detector and making it
sound a tone. Once operating an outside
search, you can use the TARGET button
to determine the location of the metal.

General Operating Instructions
Once all the proper tests and adjustments
have been made, the Metal Detector
is ready to be used outdoors.
1. When first searching, set the Mode button to
ALL METAL and SENS to the highest level.
2. Adjust the VOLUME to the desired level.
Figure 11
3. Sweep the Search Coil (19) slowly back and
forth in an arc, keeping it about 1/2” to 2”
from the ground. See Figure 11, above.
4. If you hear a beeping noise or see the
needle jump to the right on the View Meter),
you have located a metal object.
5. Use the TARGET button to pin-point the object. Then
use the DISC or TONE modes to determine what kind
of metal it is and whether you wish to dig out the item.
6. To prevent accidents, turn off the tool and
remove the batteries after use. Clean, then
store the tool indoors out of children’s reach.
Tips for Searching in Different Environments
There are many factors which influence the sensitivity
and accuracy of detecting objects, including the
angle, depth, size and oxidation of the target
object. Various soil or seawater conditions, and
also electromagnetic and electrical interference
surrounding the target can also affect readings.
Other metal detectors in the area will also cause
interference, so when there is more than one unit
in use, be sure they are at least 10 yards apart.
Some ways to help increase success are:
1. If there is interference from similar metal
detectors in your searching area, lower the
SENS setting to stop the interference.
2. If there is interference from electrical cables,
TV, radio, or other electrical devices in your
searching area, lower the SENS setting.
3. When searching in highly mineralized areas, the
unit may sound even if there is no metal. Lower the
SENS setting, set the DISC to high and increase
the distance of the Search Coil from the ground until
the false signal disappears. To set the DISC setting,
place a test metal object in highly mineralized earth
or wet sand and adjust the setting before beginning.
4. When searching in a trash area, set the DISC
to the middle setting so that the unit can reject
most invaluable metals such as nails, bottle
caps, cans, and small pieces of iron.
5. Move all metal digging tools when searching.
6. The SENS level is generally opposite the DISC
setting. The higher the sensitivity level is, the
worse the discrimination will be. You can lower
the sensitivity to have better discrimination.
