Operation

Turning on the detector
Rotate the VOLUME control away from OFF to power on the detector. After about 2 seconds the detector enters into stand-by state. At this time the default mode is DISC. LCD displays DISC of 00 and SENS of 6 bars.

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

Rotate the VOLUME control away from OFF to power on the detector.
Setting the operating mode

DISC: Press MENU, then + or – to set the DISC numeric value. If the DISC value is set 00, the detector can detector all metals. In this case, when the detector finds a target, the cursor above the target name lights. Also the detector sounds a tone, low for iron, medium for 5 cent, nickel, pull tabs, zinc, high for 25 cent or silver object. If you do not want to find the target listed on the LCD, you can set the relative numeric range of DISC by pressing DISC then + or -. For example, the numeric target range for 5 cent is 11-20, you can simply press MENU to select DISC, then set the DISC number to 21 by pressing + or -. In this case, the numeric range is beyond 5 cent. The detector will not have response to it. Neither will the detector have response to iron. Because the target numeric range is 0-10.

NOTCH: Press MENU to select NOTCH, then + or – to select the target to be notched. The cursor above the selected target will flash. Press NOTCH again, the target name below the cursor will disappear. It means this target will be notched during the detection and the detector will have no reaction to the notched target. If you want to pick up the target notched, simply press NOTCH again. Press + or -, the cursor will move from left and right. If NOTCH is not pressed within about 3 seconds, the detector will enter standby state.

NOTE : It is not recommended to notch all targets listed on the LCD. Because if you notch everything, you cannot find anything. If you want to select the setting of DISC or SENS after pressing NOTCH, you have to wait for about 3 seconds until the cursor above the target goes out.

Press MENU to select SENS then + or – to set sensitivity. The default level is of 6 bars.
Place the detector on a wooden or plastic table, and then remove any watches, rings, or metal jewelry you are wearing.
Adjust the search coil so the flat part points towards the ceiling.

NOTE: Never test the detector on a floor inside a building. Most buildings have the metal of some kind on the floor, which might interfere with the objects you are testing or mask the signal completely.

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 side of coin over search coil might cause false indication and unstable display of arrow.
PP (PINPOINT) : After you find a metal object, you can use PP to pinpoint the target. Hold down PP button. Slowly move the search coil above the sound area. The detector sounds and the signal indicator on the LCD displays the level of signal. Then release the button. Sweep the search coil again, keeping the same distance of search coil, sound disappears. Hold down PP again, closer the search coil to the sound area, the detector sounds again. Repeat the above steps until the detector displays the stronger signal where the location of the target is. Press MENU to quit the PP mode.
NOTE: TO find the exact location of target, you need to practise more times.

Target indicators

Numeric ranges of target:

IRON: 00-10
5: 11-20
P-TAB: 21-40
ZN (1) 41-60
10: 61-75
25: 76-99

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

Types of target:

IRON: It indicates that the target is probably iron.
5: It indicates that the target is probably 5 or a nickel. Some small gold rings might register within this range.
P-TAB: It indicates that the target is probably a pull tab of aluminium can. Some small gold rings might register within this range.
ZN: It is indicated that the target is probably a coin of 1 or type of metal of zinc alloy. Some medium sized gold rings might register within the category.
10: It indicates that the target might be a coin of 10. Some large rough gold items might register within this category.
25: It indicates that the target is probably 25 or a silver coin.

Tones

The detector comes with three tones for different types of metal. But the built in audio identification system sound a unique tone for each of three categories of metal. This makes it easier to identify the metal being detected. A low tone is for IRON, 5, same as for foil, bottle cap or nickels. A medium tone if ´´s for P-TAB, ZN, 1 (aluminium pull tabs, zinc or copper items). A high tone is for 25, same as 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. Depending on the quality, about 15 percent of gold rings cause the detector to sound a medium tone.

Outdoor Testing and Use

Rotate the VOLUME switch clockwise away from OFF to power on the detector.
Follow the steps of 2 described on section of Indoor Testing and Use to set the operation mode.
Find an area on the ground outside where there is no metal.
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.
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 were a pendulum. Raising the search coil while sweeping or at the end of a sweep will cause false readings.
Sweep slowly, hurrying will cause you to miss targets.
It is better you sweep the search coil from side to side on 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, 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 are searching for. Also, make sure that you are moving the search coil correctly.
NOTES:
The detector responds with a signal when it detects 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 or junk metal.
False signals are usually broken or non-repeatable.

Adjusting SENSITIVITY

After you become familiar with your detector works, it is important to fine tune the sensitivity to get a good effect. Press the touch button SENS on the panel. Then press + or – to increase or decrease the sensitivity. Then level will be displayed on the LCD.
NOTE: To detect the target deeply buried, you can adjust the SNS 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.

Using LIGHT

In dark area, you can use LIGHT for better searching. Press MENU to select LIGHT. Then press +or – to adjust the level (0-9) of LIGHT. The level will be displayed on the LCD.
NOTE: As the light consumes more power, we suggest you setting the value to 0 in normal environment.

Factors That Affect the Detecting

It is 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.
Electromagnetic and electrical interference surrounding the target. In area of highly mineralized ground or wet sand, the detector will sound even uf there is no metal. In this case, you can lower the sensitivity or increase the DISC number. Meantime enhance the distance between the search coil and the ground. In area with trashy metal, you can set DISC numeric value to 50. In this case most nails and small pieces of iron will be eliminated. Metallic digging tolls will also affect the detection of they are near the search coil. So it is better place them a little far away.

Care and maintenance

Your 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.

Handle the detector gently and carefully. Dropping it can damage circuit boards and cases and can cause the detector to work improperly. Use the detector only in normal temperature environments. Temperature extremes can shorten the life of electronic devices damage the cases of the detector.

Wipe the detector with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the detector.

Keep the detector away from dust and dirt, which can cause premature wear of parts.

Code of Ethics for Treasure Hunters

Remember that every treasure hunter should follow these ten commandments:

Before you search, make sure that the search site for the place where you want to search is not restricted by any laws or regulations. If so, respect them.
Do not damage nature, sown fields, roads, or trees, do not start a fire in the forest.
Backfill the pits that you will dig so that after the first rain it is not known that the place has been dug in.
Take everything you dig out. Do not leave cans, pipes, wires, and other debris in the woods.
Be quiet and considerate. Best so that no one knows about you. Do not spread piles of leaves or sticks in the forest.
Be careful – try to see and not be seen. Not all forest visitors have good intentions.
Do not drive to the forest, leave the car in a safe place, and walk to the site.
Do not enter reservations and other places where it is prohibited.
Do not disturb the animals unnecessarily.
Report important findings as required by law.
