LAYOUT OF THE CONTROL PANEL
1. Target ID indications
|Metal range||IRON||GOLD RANGE||SILVER RANGE|
|Target||Bo type ca||Foil||Pull tab||10||100||250||250+|
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.
- 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.

2. Position the Detector:
- Place the detector on a table with the search coil hanging over the edge.
- 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.
- Turn off equipment that may interfere with electromagnetic radiation.
- Pivot the search coil back.
- 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:
- Press MENU until DISC is displayed on LCD.
- Press “+” once. The bottle cap(iron) indicator will disappear.
- Wave the bottle cap. It will not be detected because it has been “discriminated out.”
5. Using NOTCH Feature:
- Press MENU until NOTCH is displayed on LCD.
- 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.
- 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:
- Press and hold the “PINPOINT” button, PP will appear on the LCD display.
- Hold a coin motionless over the search coil.
- Sweeping coin over search coil.
- Notice that the sound changes as the coin moves closer or further.
- Notice that the depth indicator changes as the coin moves up and down.
- Press MENU until SENS is displayed on LCD.
- Press “+” or “-” to set the SEN. The sensitivity level can be set from 1 to 10.
8. Adjusting VOLUME
- Press MENU until VOLUME is displayed on LCD.
- Press “+” or “-” to set Volume. The volume level can be set from 0 to 10.
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.
- Find a place outside where there is no metal.
- Place a sample you want to find on the ground.
- Press POWER to turn on the detector.
- 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.
- 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.
- Press and hold PP to activate the Pinpoint feature.
- Move the search coil slowly across the target, and you can locate it by sound.
Narrow the Detection Rage:
- To narrow the response further, position the search coil near the target.
- Press the PP button and hold, moving the search coil slowly.
- When you hear the sound, you can release the PP.
- And then press PP to continue the detection. In this way, you can narrow the range of the target.
- Repeat the above steps.
When the coil moves to the center of the target the signal from the detector is the strongest.

How do you activate a metal detector? ›
To use a metal detector, stand in a comfortable position and extend or retract the stem so that the coils hover just above the ground when you hold the unit. Walk slowly as you swipe the machine from side to side.What do the different beeps on a metal detector mean? ›
You will learn which sounds indicate a valuable metal and which not. Valuable metals like gold or silver will probably make a high pitch beep on your metal detector, low value metals like iron will make a dull beep. You can even “screen out” certain metals so you will only hear a sound when a valuable metal is located.What is the farthest depth a metal detector works? ›
Are you curious about metal detecting, and wondering how deep a metal detector can go? Most metal detectors can detect objects about 4-8ʺ (10 - 20 cm) deep. In ideal conditions, a mid-range metal detector can reach 12-18ʺ (30-45 cm) underground. Some specialized detectors can go as deep as 65' (20 m).What setting do you put a metal detector on? ›
Many detectors can chatter from EMI when set to the maximum sensitivity or gain levels. Especially if you live in the city around large power lines and multiple WiFi and cellular signals bouncing around the area. Less is more for the first time user. Set it to 7 of 10 or (70 of 100) as a good starting point.Can a metal detector find a wedding ring? ›
Endless amounts of rings, watches, necklaces and earrings can be picked up with a metal detector. People playing Frisbee, volleyball or frolicking on the beach don't even realize when their ring falls loose or clasps break on necklaces and bracelets.Can metal detectors detect keys? ›
Fortunately, a metal detector can find keys. Most keys have metal conductors as their base, so a detector can quickly locate them.Why is my metal detector constantly beeping? ›
The most common reasons your metal detector beeps too often are: Low batteries. Moisture in cable connections or control box. Bad coil.What is the best frequency for detecting gold? ›
The frequency you choose will depend on the type of metal you are searching for. The best place to find ferrous metals and iron is at 10 kHz and higher. Gold can be found at 14 kHz and higher. At frequencies between 3 kHz and 7 kHz, silver, copper, and brass can be found.What does gold show up as on metal detector? ›
Q: Will any metal detector find gold? Yes. Most metal detectors are capable of finding gold but some will do a much better job than others. Since gold has rather low conductivity, metal detectors that use higher frequencies will spot gold better than low frequency detectors.Can a metal detector find gold nuggets? ›
The answer is YES, they all do. Some do it better than others. Some detectors like the Minelab Gold Monster or GPZ 7000 are specifically designed to find small gold pieces (which most naturally occurring gold is). When it comes to finding gold rings, just about any metal detector will work.
How do you make a metal detector more powerful? ›
- sweep the coil close to the ground.
- increase the sensitivity setting.
- reduce the discrimination setting.
- install fresh batteries.
- upgrade to larger coil.
A realistic depth to detect a fair size nugget is around 1,5 meters with the best gold prospecting machine on the market, the Minelab GPX5000. Depending on soil condition and nugget size a 1,5 meter depth is a realistic max depth for a large nugget. Deeper than 1,5 meters is not realistic.What is the best sensitivity for metal detector? ›
Ferrous metals, such as steel and iron, are the easiest to detect because they have the most effect on the sensing field. Nonferrous metals, such as copper, aluminum, brass, and lead are almost as easy to detect and have a multiplier of approximately 1.1 times ferrous sensitivity.Why won't my metal detector detect gold? ›
Rich gold ore where the gold is finely dispersed in the rock will be hard to detect or undetectable. Wiry or spongy masses of gold are hard to detect. Jewelry hunters run into this when trying to detect lost necklaces.How do you use a sensitivity on a metal detector? ›
While holding your Prospector Metal Detector as indicated in the picture to the right, sweep the search coil slowly from side to side. While sweeping, maintain the search coil level with the ground. If the detector chatters, reduce the sensitivity by turning the left knob (Sensitivity) counterclockwise.Can a metal detector find diamonds? ›
This leads to an important point: metal detectors will not detect non metal items such as gemstones, diamonds and pearls. What a metal detector can do is lead you to indicator minerals, which are used by prospectors. Prospectors follow the indicator trail back to gold or the volcanic pipe which may contain diamonds.What is the most valuable find with a metal detector? ›

Oversized and metallic jewelry can trigger the alarm, so it's best to put it in your carry-on, where it won't set off the metal detector. In fact, TSA actually recommends that you keep your jewelry on (with the exception of large or metallic pieces).Will a CD set off a metal detector? ›
They can't detect what is being stolen from warehouses and distribution centers today. This includes small electronics, pharmaceuticals and cosmetics, apparel and other soft goods, CDs and DVDs, USB sticks, groceries and alcohol. Anything made of plastics, ceramics, wood or organic materials.Can metal detectors detect through snow? ›
Yes, you can metal detect in the snow. However, if the snow is deep, your detector won't penetrate the ground as far as you'd like. Find areas where snow drifts haven't piled or the wind has blown some of the ground clear.
Will a metal detector find my keys in snow? ›
When using a metal detector in the snow to find lost keys, try to keep the detector as low to the ground as possible. Metal detectors work best when close to the object and snow can add distance the same way as dirt. Sweep slowly, parallel to the ground and even push snow with the detector coil to scan deeper.What causes a metal detector to go off? ›
When the field strikes that . 38 special in your pocket, there is generated a tiny electrical current, which produces a radio signal, which is picked up by the detector's antenna. The signal is amplified and analyzed, then, maybe, the alarm goes off.What interferes with a metal detector? ›
Possible sources of ground loops are loose nuts or bolts, poorly designed reject devices, degenerating bearings in an idler or drive pulley, or even another piece of machinery bumping up against the metal detector system.What is metal detector chatter? ›
Electrical interference can cause a metal detector to “chatter” spontaneously, to lose sensitivity for no apparent reason, or to cause periodic audio “wobble” or slow waves of spontaneous sound.Where is the best place to find gold with a metal detector? ›
The best gold mining areas in California are in 3 distinct regions; in the Sierra Nevada Mountains, further north in the Siskiyou and Trinity Mountains, and in parts of the Mojave desert in southern California.What is the difference between gold detector and metal detector? ›
Gold is a metal, so a Metal Detector is capable of finding gold, and vice-versa, a Gold Detector is also capable of detecting various metals. Metal Detectors are primarily used by hobbyists who are looking to find a wide range of metals including, relics, artefacts, coins, jewellery including silver and gold.What is the frequency of silver? ›
The threshold frequency of silver is 9.71×1015 Hz.What metals Cannot be detected by a metal detector? ›
Metal detectors are good for finding silver, gold, and jewelry. So, the question of whether or not it can locate diamonds seems to make sense. But as mentioned, metal detectors can only locate ferrous and non-ferrous metals. So, it will not detect diamonds as they do not have metallic properties.Can metal detectors detect phones? ›
On top of that, they're expensive to replace—the average cost of a new smartphone in 2021 is between $600 to $1000. But you can find your lost phone with a metal detector. Whether it's an iPhone or Android, there's a lot of metal inside them.Does gold stick to a magnet? ›
If it's real gold it will not stick to the magnet. (Fun fact: Real gold is not magnetic.) Fake gold, on the other hand, will stick to the magnet.
Do all creeks have gold in them? ›
Not every creek and river out there has gold. From a practical sense it would be fair to say that most of them don't have any gold, or there is so little gold that it would be a waste of time trying to find it. Taking some extra time to research good locations is time well-invested.Can I find gold in any river? ›
Every river in the world contains gold. However, some rivers contain so little gold that one could pan and sieve for years and not find even one small flake. The amateur prospector will not be able to determine whether gold is contained within an outcrop of rocks.Can you calibrate a metal detector? ›
A metal detector, however, has no international standard to which it can be “calibrated” (again, calibration and verification). There is a wide variety of variables that affect a detectors capabilities. Most important among those fluctuations is the product itself.How do you set the ground balance on a metal detector? ›
Metal Detecting 101 - Ground Balancing - YouTubeShould a metal detector touch the ground? ›
For best results keep your metal detectors coil as low to the ground as possible. An inch or less above the ground, but not scraping the ground.Will a metal detector find silver? ›
Myth Four: “Metal detectors can only find ferrous metals.”
In fact, metal detectors can find non-ferrous metals that include gold, silver, and even aluminum. If it is made of metal, your metal detector can find it.
Using Metal Detectors
Metal detectors double as both a tool and a trick and they help burglars out a great deal, especially once they make their way into your home or office.
Between $500 and $1,000: More technology costs more money, so don't be surprised when more capable metal detectors come with a bump in price. More than $1,000: For more than $1,000, you'll get premium metal detectors fit for an archeological dig.Can metal detectors detect steel? ›
Metal detectors have a tough time detecting metals like stainless steel, which have very poor electrical conductivity. Stainless steel has low magnetic permeability, which means it does not produce a signal strong enough to be detected. Other items that metal detectors won't be able to locate include: Gemstones.What is threshold on a metal detector? ›
Threshold. Threshold is the continuous sound used to listen for target signals. The Threshold will 'blank' to indicate the detection of a discriminated/rejected target. When a Threshold is too high, a faint signal is masked and only the peak of the loud sound is audible above the Threshold.
How do you measure sensitivity of a detector? ›
The sensitivity S of a detector is its response y divided by its excitation x. As for the minimum detectable excitation xmin is called the detectivity D of the detector and it is set by the noise in the detector. If the signal is immersed in the noise it could not be directly detected.What do the different beeps on a metal detector mean? ›
You will learn which sounds indicate a valuable metal and which not. Valuable metals like gold or silver will probably make a high pitch beep on your metal detector, low value metals like iron will make a dull beep. You can even “screen out” certain metals so you will only hear a sound when a valuable metal is located.What do the numbers on a metal detector mean? ›
Then, when you look at the LCD display on your detector, you'll see numbers and/or bars illuminated on the screen. This is the Target Identification indicator. It indicates which type of metal is being transmitted. Usually, the target Identification has an iron section, a gold range and a silver range.Does gold beep with metal detector? ›
Jewellery will only set off metal detectors if it's made from magnetic metals. This means that you don't need to remove good-quality rings, necklaces, bracelets and piercings if they're made from silver, gold or platinum.How do you use a metal detector effectively? ›
