Preparation
Assembling the detector
Assembling your detector is easy and requires no special tools. Just follow these steps.
- Insert the coil cable plug into the 5-pin jack connected with S stem.
- Sheathe the lower stem on S stem and secure with the fixing knob.
- Turn the stem’s locknut clockwise until it loosens. Lengthen or shorten the stem so when you stand upright with the detector in your hand, the search coil is level with and about one half to 2 inches above the ground with your arm relaxed at your side.
- Then turn the stem’s lock mut counter-clockwise to lock it in place.
- Loosen the knobs at the search coil’s end, then adjust the search coil to desired angle. (The search coil should be parallel with the ground.) Tighten the knobs just enough to keep the search coil from rotating or wobbling.
- Insert the latch on the top of the handle into the assembly hole on the bottom of the control box. Then slightly push the control box in the direction of IN marked on the handle to fix the latch in place, secure the control box with fixing screw properly.
- Unscrew the knob on the search coil and remove the knob connector. Insert the stem and align the holes on the search coil bracket and the stem. Push the connector through the holes and tighten the knob.
- Wind the search coil cable around the stem. Leave enough slack in the cable. Insert the search coil cable plug into the five-pin jack on the front control box’s housing.
- Turn the stem’s lock nut clockwise until it loosens. Lengthen or shorten so when you stand upright with the detector in your hand, the search coil is level with and about ½ to 2 inches above the ground with your arm relaxed at you side. Turn the stem’s lock nut counter-clockwise to lock it in place.
CAUTION:
- The search coil’s plug fits into the connector only one way. Do not force the plug or you could damage it.
- Do not over tighten the search coil or use tools such as pliers to tighter it.
Installing batteries
- Turn off the power before installing the batteries.
- Slide the left and right battery covers off in the direction of the arrow.
- Place two 9V batteries into the battery compartment matching the polarity symbols (+ and -) marked inside.
CAUTIONS:
- Use only fresh alkaline batteries of required size.
- Do not mix the old and new batteries of different types of batteries.
- Dispose of old batteries promptly and properly. Never bury or burn them.
- If you do not plan to use the unit for a week or more time, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.
Using Headphones
- Insert the headphones’ 3.5mm plug into the PHONE jack. At this time the internal speaker disconnects.
- Set the VOLUME to the desired level.
LISTENING SAFETY:
- To protect your hearing, set the volume to the lowest setting before you begin listening, adjust the volume to a comfortable level.
- Do not wear headphones while operating your detector near high-traffic areas. Pay attention to traffic safety.
Functions and indications
A quick look at the detector
Displays
The LCD displays the detection mode, sensitivity level, battery condition, volume level and the depth of target. When the detector finds an object, an arrow appears below the target icon. Also displays the depth of the target.
Target denomination
IRON NAIL: indicates that the target is probably iron or nail. Some oxidized iron might register somewhere within the SILVER range.
AL/5 /PULL TAB: indicates that the target is probably 5, aluminum can pull tab, or a nickel.
GOLD RANGE: indicates that the target is probably a gold ring. Some bronze objects might register within this range.
1 – indicates that the target might be a coin of 1 or zinc penny or a copper coin. Some large rough gold items or bronze objects might register within this category.
SILVER RANGE
- 1 – indicates that the target is probably 1 or 10 coins.
- 10 /25 /1 – indicates that the target is probably a silver coin, 10 /25 /1 . Some large aluminum coins might register within this category.
- 50 – indicates that the target is probably 1, 50, or a silver coin.
Tones
There are three tomes for different kinds of metal types. This makes it easier to identify the metal being detected.
When the detector finds iron, nail, bottle caps, it sounds a low tone. A medium tone is for 5, 1, 10, some gold rings, aluminum pull tabs, zinc, or copper items. A high
tone is for 25, 50, 1, or silver items.
Operation
- Press POWER button to turn on the detector. Pres POWER again to power off. LCD displays all symbols.
- SETTING SENSITIVITY
Press SET, sensitivity level bar flashes. Then press UP button to higher the sensitivity or press DOWN button to lower it. After that, press ENTER to confirm the setting. - SETTING VOLUME
Press SET three times; the volume icon flashes. Press UP button or DOWN button to higher or lower the volume level. Then press ENTER to confirm the setting. - SETTING THE OPERATION MODE
The detector comes with three operating modes of ALL METAL, DISC, PINPOINT.- ALL METAL: used for detecting all types of metal.
Press SET twice, then ENTER to get ALL METAL. In this mode, the unit can default all kinds of metal. - DISC: Used for target discrimination. You can set the target range or eliminate the target you do not want by pressing SET and MODE buttons. Press SET twice, the blank frame flashes, press UP or DOWN to choose the target you do not want. Then press MODE: You can choose several targets to be eliminated. After that press ENTER to confirm the selected target to be eliminated. To pick up the eliminated items, simply press MODE before pressing ENTER. Or repress SET twice and UP or DOWN to move the flashing frame to the target you want to pick. Then press MODE and ENTER.
NOTE: A crossed frame is for item eliminated.
- ALL METAL: used for detecting all types of metal.
- PINPOINT
After you find a metal object, you can use P/P to pinpoint the target. Hold down P/P button. LCD will display P/P and an icon of eye. Slowly move the search coil above the sound area. The detector sounds and the depth indicator on the LCD displays the probable depth of the target. Then release the button. Sweep the search coil again, keeping the same distance of search coil, sound disappears Hold down P/P 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.
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
- Press POWER to power on the detector.
- Follow the instructions described in OPERATION to set SENSITIVITY, VOLUME, and operation mode.
- Place the detector on a wooden or plastic table, then remove any watches, rings, or metal jewellery 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 metal of some kind in 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.
Outdoor Testing and Use
- Press POWER to power on the detector.
- Follow the instructions described in OPERATION to set SENSITIVITY, VOLUME, and 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.
The detector can detect the metal type with blank frame below the target name. And an arrow displays below the target if it is found. Meanwhile the detector rejects or does not respond to other metal types with cross mark in the frame X displaying below the target name. When the detector finds any metal, it sounds a tone. A low tone is for iron, nail, bottle caps. A medium tone is for 5 , 1 , 10 , some gold rings, aluminium pull tabs, zinc or copper items. A high tone is for 25 , 50 , 1 or silver items. 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.
- 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.
- When the detector detects a buried target, continue sweeping the search coil over the target in a narrowing side-to-side motion.
- Make a visual note of exact spot on the ground where the detector beeps.
- Stop the search coil directly over this point on the ground. Then move the search coil straight forward away from you and straight back towards you a couple of times.
- Repeat steps 1 – 3 at a right angle to the original search line. Make a mark of “X”. The target will be directly below the “X” at the point of the beep response.
Troubleshooting Guide
| Problem | Reason | Suggestion |
| The detector displays or sound without detecting any target. | 1. The detector ma 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 proximity. |
1. Reduce sensitivity.
2. Sweep the search coil more slowly and hold 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. |
1. Increase sensitivity.
2. Recover all target range. |
| 3. Search coil is not parallel with the ground. | 3. Adjust the search coil angel to be parallel with
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 cannot 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.
2. Dead battery. |
1. Re-pug it properly.
2. Replace batteries. |
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.
- Electro-magnetic and electrical interference surrounding the target. If you detect patiently and correctly and practise more times, you will ger satisfactory result.
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.
