SEARCH MODES

The detector includes four search modes: A/M (ALL METAL), DISC (DISCRIMINATION), MEMORYJEWELRY. Select the mode that suits the targets you hope to find.

01 A/M (ALL METAL) MODE

This mode is designed to detect all types of metal.
Press MODE to select A-M (ALL METAL) mode. A-M is displayed on LCD. This means ALL METAL mode is selected. You can detect all kinds of metal.

02 DISC (DISCRIMINATION) MODE

The DISC mode can eliminate the unwanted metal targets and works with “+”.

A  Press MODE 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 left to right. 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 silver target such as one dollar coin or 25 cent can’t be eliminated. Because they are valuable.
C  To pick up the eliminated target ID, simply press and the recovered target icon(s) will be displayed again on LCD.

03 MEMORY MODE

The detector is designed to detect the only memorized metal target.
Press MODE to select MEMORY. MEMORY is displayed on LCD. This means MEMORY mode is selected.

This mode is designed to detect the only memorized metal target. For example, if you want to find Icent coin, sweep a sample of (cent over the search coil. The detector will memorize the target. LCD only displays the memorized target icon and other target icons will be removed. In this case the detector will only detect Icent coin and will have no response to other metal targets.

04 JEWELRY MODE

This does not mean that the detector will search only for jewelry while in JEWELRY Mode. It simply indicates that the discrimination pattern is optimized for locating most jewelry items. The JEWELRY mode will still find coins, relics and other non-jewelry items. It ignores most nails and small iron pieces automatically.

05 PP MODE

01 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. Also the digital value of the target and depth are displayed on LCD.
02 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.

ADJUST SENSITIVITY LEVEL

The metal detector are highly sensitive and have adjustable sensitivity.
Setting the correct sensitivity level for individual detecting conditions will maximize the detection depth. It also helps to reduce interference items and reduce noise. Improve the accuracy of metal detection.
Press SENS , then + or-to increase or decrease the sensitivity.

01 Hold the coil stationary, then use the Sensitivity Plus button to increase the sensitivity until false signals begin to occur.

02 Reduce the sensitivity level by pressing the Sensitivity Minus button, just enough that the false signals disappear.

03 Sweep the coil over a clear patch of ground, and reduce the Sensitivity Level further if any ground noise is encountered.

PINPOINT (PP)

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

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. Also the digital value of the target and depth are displayed on LCD.

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.

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.

01 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. CORRECT SWING
2. INCORRECT SWING

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

03 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.

If the detector detects the item, it sounds a tone, and the target icon flashes. Also LCD displays the digital value of target as well as the depth.

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 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. normal environment.

NOTES:

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

FACTORS THAT AFFECT THE DETECTING

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

01 The angle of the target buried in the soil.

02 The depth of the target.

03 The level of oxidization of the target.

04 The size of the target.

05 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

Problem

| Reason| Suggestion
---|---|---

The detector displays or sounds without detecting any target

|

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 electromagnetic interference
2. Sweeping the detector’s search coil too fast or at 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 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 not function.

|

1. Five-pin cable not connected well
