• DON’T use carbon batteries.
• DO NOT MIX OLD AND NEW BATTERIES.
• CHECK THE BATTERIES if your detector exhibits any of the following symptoms:
  The unit does not turn on.
  Low speaker volume.
  The unit beeps continuously at a low sensitivity setting.

Follow these steps to install the batteries.

1. Turn off before installing the batteries.
2. Take off the battery cover.
3. Place two 9V alkaline batteries into the battery compartment matching the polarity symbols (+ and -) marked inside.

Warning:
Dispose of old batteries properly. Never bury or burn them.

2. Insert the headphones’ 3.5mm plug into the headphone jack at the bottom of the control box. At this time the internal speaker disconnects.

LAYOUT OF THE CONTROL PANEL

LCD DISPLAY

1. Target ID indications

2. SENS (Sensitivity): Adjust the sensitivity from 1 to 10. The higher the number, the more sensitive the detector. This sensitivity control does not affect Pinpoint sensitivity.
If the detector beeps erratically or beeps when there are no metal objects being detected, reduce the sensitivity.
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.
3. VOLUME : Adjust the volume level from 0 to 10.
4. DISC: Discrimination is an important feature of professional metal detectors. It allows users to ignore trash and unwanted objects.
The DISC control is the Discrimination function of the detector. In its default setting, all metals are detected. Use this DISC function in order to eliminate unwanted types of metals from detection. You only need to eliminate the targets in order. Each time you press the “+” button, a target will disappear. The target disappears means that the category is eliminated from detection. To pick up the eliminated target category, press “-” and categories will be accepted back in order.
Notice: The two targets on the right cannot be eliminated. These two targets represent silver or other high-value targets, which are generally desirable. So the detector does not allow them to be discriminated out.
5. NOTCH: It is similar to Discrimination（DISC）. It allows you out of turn to accept or reject different types of metals. The DISC can only accept or reject metals in order.
The NOTCH Mode is only applicable in FOIL, 5¢, ALUM, and 1¢ these four categories. Press “+” or “-” to a new category. The target ID will flash for 3 seconds and then it will change to the opposite state. Or press MENU while the target ID is flashing, and then it will change to the opposite state. If the target had been illuminated previously
and disappears now indicates that the target has been eliminated from detection. As same, the target disappeared before and illuminates now indicates that target is notched in
or can be detected.

CONTROL BUTTONS

• POWER: Press the button to turn on the detector. Press it again to turn off the detector.
• MENU : Press MENU to make it active and select operation mode(NOTCH or DISC), set SENS or VOLUME.
• INCREASE ( +): Increase the level of sensitivity or volume and the range of DISC (discrimination) or NOTCH.
• DECREASE (-) : Decrease the level of sensitivity or volume and the range of DISC (discrimination) or NOTCH.
• PINPOINT: Press and hold for precision target pinpoint at any time.

TESTING THE DETECTOR

Supplies Needed:

• A bottle cap (made of iron)
• A nickel(5¢)
• A Gold Ring|  • A quarter (25¢)
• A Penny(1¢)
• A dime(10¢)
---|---

2. Position the Detector:

1. Place the detector on a table with the search coil hanging over the edge.
2. Be sure that the search coil is far away from walls or metal objects. Keep the search coil away from any metal in the table.
3. Turn off equipment that may interfere with electromagnetic radiation.
4. Pivot the search coil back.
5. Press POWER to turn on.

3. Using ALL METAL Feature：
Wave all objects over the search coil and notice the different tones.
4. Using DISC (Discrimination) Feature:

1.  Press MENU until DISC is displayed on LCD.
2. Press “+” once. The bottle cap(iron) indicator will disappear.
3. Wave the bottle cap. It will not be detected because it has been “discriminated out.”

5. Using NOTCH Feature:

1. Press MENU until NOTCH is displayed on LCD.
2. Press “+” twice， 5¢ will flash for 3 seconds and disappear which means 5¢ is “notch out” (eliminated). To eliminate 1¢, press“+” until 1¢ flash and disappear.
3. Wave 5¢ or 1¢ over the search coil. 5¢ and 1¢ will not be detected because they have been “notched out”(eliminated). Notice: the target categories that disappear on LCD can not be detected.

If you want to pick up the target type you eliminated before, Press “+” or ” – ” to the target, and then wait for the target to flash for 3 seconds, or press the MEMU button when it is flashing.
Using PINPOINT Feature:

1. Press and hold the “PINPOINT” button, PP will appear on the LCD display.
2. Hold a coin motionless over the search coil.
3. Sweeping coin over search coil.
4. Notice that the sound changes as the coin moves closer or further.
5. Notice that the depth indicator changes as the coin moves up and down.

Adjusting SENS(Sensitivity)

1. Press MENU until SENS is displayed on LCD.
2. Press “+” or “-” to set the SEN. The sensitivity level can be set from 1 to 10.

8. Adjusting VOLUME

1. Press MENU until VOLUME is displayed on LCD.
2. Press “+” or “-” to set Volume. The volume level can be set from 0 to 10.

OVERLOAD WARNING
If a metal object or highly magnetic soil is too close to the search coil, the detector will overload, and “- – ” will appear on the LCD display. The detector will make a rapid, repeating mid-tone warning sound. Overload will not harm the detector, but the detector will not function in these conditions. If overload occurs, keep the search coil away from the target.
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.

OUTDOOR DETECTING

1. Find a place outside where there is no metal.
2. Place a sample you want to find on the ground.
3. Press POWER to turn on the detector.
4. Swing the search coil gently from side to side, slightly overlapping each sweep as you move forward. Keep your search coil approximately 1-2 inches above the ground as you search.

Notes:

• Raising it during the sweep, or at the ends of your sweep, can cause false readings.
• Move slowly; hurrying will cause you to miss targets.
• Most desirable objects will respond with a repeatable tone. When discriminating, iron and foil objects generally do not respond.
• False signals can be caused by trashy ground, electrical interference, or by large irregular trash objects. These signals are easily recognized by their often broken or non-repeatable nature.

DETECTING WITH PINPOINT

After you find a target, you can use PP(Pinpoint) to find the exact location of the target as follows.

1. Press and hold PP to activate the Pinpoint feature.
2. Move the search coil slowly across the target, and you can locate it by sound.

Narrow the Detection Rage:

1. To narrow the response further, position the search coil near the target.
2. Press the PP button and hold, moving the search coil slowly.
3. When you hear the sound, you can release the PP.
4. And then press PP to continue the detection. In this way, you can narrow the range of the target.
5. Repeat the above steps.

When the coil moves to the center of the target the signal from the detector is the strongest.

Troubleshooting Guide

detector may receive interference and the false signal from the broadcast antennas and other electronic lines.
2. The humidity of the 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 electromagnetic interference.
2. Sweeping the detector’s search coil too fast or at the wrong angle.
3. Using 2 detectors in close 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 the sensitivity. 2. Recover all target range.
angel to 3ust the search coil is parallel to the
ground.
LCD displays multiple target categories or emits several sounds at once.| 1 . There may be over one kind of metal target.
2. The detector can’t identify the target. Sometimes, oxidized metal also causes the excursion of the target arrow and tone.| 1. Reduce the sensitivity to eliminate the detection of the deeper target.
2 Sweep the search coil with different angles.
No power, no sound.| 1. Five-pin cable not connected well.
2. Dead battery.| 1. Re-plug it properly. 2. Replace batteries.
