SEARCH MODES
The detector includes four search modes: ALL METAL, DISC (DISCRIMINATION), NOTCH, PINPOINT. Select the mode that suits the targets you hope to find.

• ALL METAL Mode
  This mode is designed to detect all types of metal.
  If you don’t set the discrimination range or no metal target is eliminated, in this case, the detector can detect all kinds of metal.

• DISC (DISCRIMINATION) Mode
  The DISC mode can eliminate unwanted metal targets one by one and works with “+”.

• NOTCH Mode
  The NOTCH mode can eliminate any unwanted metal target and works with “+” or “-“ and “ENTER”.

OPERATION

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.

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.

1. 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.
   

2. Sweep slowly, hurrying will cause you to miss targets.

3. It’s better to 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.

If the detector detects the item, it sounds a tone, an arrow appears under the target icon. Meanwhile LCD displays the digital value and the depth of target.
If the detector does not detect the item, make sure that the mode is set correctly for the type of metal you’re searching for and 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.
• 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 target.

TEST PROCEDURE

Turning on the detector Setting the mode Adjusting sensitivity Find a ground without metal Place the test metal Start testing

SETTING THE OPERATION MODE

1. ALL METAL mode:
   When DISC value is 00, or no target icon is eliminated, you can detect all kinds of metal.
   

2. DISC (DISCRIMINATION) Mode
   
   The DISC mode can eliminate the unwanted metal target(s) and works with “+”.
   a. Press MENU to select DISC. DISC is displayed on LCD. This means DISC mode is selected.
   b. Press “+” to eliminate the unwanted target(s) in sequence from IRON to 1 cent. The eliminated target icon(s) will disappear on LCD. The detector will not detect such target(s).
   User can select several targets to be eliminated by using DISC mode. But 10 cent and 25 cent can’t be eliminated. Because they are valuable.
   c. To recover the eliminated target ID, simply press “–” and the recovered target icon(s) will be displayed again on LCD.
   Note: The DISC setting range is 00-80. The detector will memorize the setting before turning off the power.

3. NOTCH Mode
   
   Press MENU to select NOTCH. NOTCH is displayed on LCD. This means
   NOTCH mode is selected.
   This mode allows you to eliminated undesired metal target by using “+” or “- “ and ENTER control buttons. For example, if you don’t want to find 5cent coin, you can press MENU to select NOTCH. Then press “+” or “-“ to move the arrow to 5 cent. Then press ENTER to confirm the elimination. The 5 cent icon will not appear on LCD. The detector will not have response to 5 cent.
   You can use NOTCH mode to eliminate any undesired metal target.
   To recover the eliminated target, simply press “+” or “-“ to move the arrow to the relative eliminated target icon, then press ENTER.
   Note: The detector will memorize the setting before turning off the power.

ADJUSTING SENSITIVITY
Press MENU to select SENS, SENS will appear on LCD. Then press + or – to set the desired sensitivity level. LCD will display the level.
Note: Cell phones, cell phone towers, etc… all produce interference signals and will cause the detector to beep when no metal is present, and sometimes to beep erratically.
If the detector beeps erratically or beeps when there are no metal objects being detected, reduce the sensitivity.
Note: The detector will memorize the setting before turning off the power.
ADJUSTING VOLUME
Press MENU to select VOL. VOL will appear on LCD. Then press + or – to set the desired volume level. LCD will display the digital level of volume. The volume level can be adjusted from 00-05.
Note: The detector will memorize the setting before turning off the power.

TARGET INDICATIONS

Target| **Iron| 5 cent Nickel| Pull tab Aluminum| 1cent/zinc S-caps| 10 cent Copper| 25 cent Silver coin
---|---|---|---|---|---|---
Tone| Low| Low| Medium| Medium| High| High
****ID Display| **| | ****| | |
Digital value| 1-15| 16-30| 31-50| 51-70| 71-85| 86-99

Note: There is a wide variety of metals and no target can be identified for certain until unearthed. This table is for general reference only.

USING BACKLIGHT

In dark area, you can use BACKLIGHT for better searching. Press BACKLIGHT button to turn on the backlight. Press it again to turn the light off.

Note:

• As the light consumes more power, it’s better to turn off the backlight in normal environment.

PP (PINPOINT)
After you find a metal object, you can use PP to pinpoint the target.

1. Press PP button, “PP” on LCD flashes. When LCD displays steady “PP”, you can start to move the search coil slowly above the sound area. If the detector finds the target, it sounds a tone and the target depth signal will appear on LCD.
2. Press PP button again. After steady “PP” displays, sweep the search coil, keeping the same distance of search coil, sound disappears. Closer the search coil to the sound area, the detector sounds again.

Repeat the above steps until the detector displays the constant signal where the location of the target is.
To exit the PP mode, press PP again.

FACTORS THAT AFFECT THE DETECTING

It’s difficult to have an accurate detecting result. Sometimes the detecting may be restricted by some factors:

• 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.

In area of highly mineralized ground, or fertile ground, or wet sand, the detector will sound even if there is no metal. In this case, you can lower the sensitivity.
Meantime enhance the distance between the search coil and the ground.
Metallic digging tools will also affect the detection if they are near the search coil. So it’s better place them a little far away.

Troubleshooting Guide

1. The detector may receive interference and false signal from broadcast antenna and other electronic lines.
2. The humidity of environment may be extremely high

|

1. Change searching place
2. Wait for some time to check again

The detector sounds false signals.|

1. Sensitivity set too high/ environmental
2. electromagnetic interference
3. Sweeping the detector’s search coil too fast or at wrong angle
4.  Using 2 detectors enclose proximity

|

1. Reduce sensitivity
2. Sweep the search coil more slowly and hold the detector correctly.
3. Keep two detectors at least 6 meters(20’) apart

The detector does not detect anything|

1. Sensitivity set too low
2. Target range is eliminated
3. Search coil is not parallel to the ground

|

1. Increase sensitivity
2. Recover all target range.
3. Adjust the search coil angel to be parallel to the ground

LCD display multiple target categories or emits several sounds at once|

1. There may be over one kind of metal targets
2. The detector can’t identify the target.Sometimes, oxidized metal also causes the excursion of target arrow and tone.

|

1. Reduce the sensitivity to eliminate the detection of the deeper target
2. Sweep the search coil with different angles

The detector does nonfunction.|

1. Five-pin cable not connected well
2. Dead battery

|

1. Re-plug it properly
2. Replace batteries
