Gold Metal Detector Introduction

This metal detector can be used for the detection and identification of metals buried underground. It is easily operated, has high resolving power and is extremely accurate.
There are various kinds of mineral in the soil, and they can interfere with the detection of the target metal object. The soil signal interference is called the effect of mineralization. The detector has been equipped with advanced ground balance system which is very effective in eliminating the soil signal interference. Therefore, depth of detection is enhanced enormously.
It is furnished with two search heads. Under common situation such as indoors or in the place of complex soil condition, you had better use the small one. Using the small search head, the metal detector operates stably, discriminates accurately and has powerful anti-interference capability. If you want to detect outdoors in the area of homogeneous soil and the target is buried deeply, you can use the large one. Using the large search head improves the depth of detection, but the detection is liable to be disturbed by the stray wave.

Metal Hunting

Connect the storage battery to the detector with the storage battery cable. Turn on the power switch of the storage battery and the power switch of the detector. The detector has a short preheating time after it is turned on. During the course of preheating, the search head should be lifted off ground and stays still in the air. If the meter needle returns to the "0" position and will not deviate after you press and release the push button, the preheating is over. User can begin to detect metal.
The detector has been supplied with two search heads, one large, and one small. When using the small one, the detector works stably and locates accurately, but the detection depth is relatively small. When using the large one, the detector may reach the maximum depth of detection, but stability is lower. Freshman is apt to seek after the detection depth blindly and likes to use the large search head first at the beginning of detection, as a result of complex geological structure, the detector sounds everywhere so that nothing can be ascertained. It is recommended that the small search head be used at beginning under general condition, especially in the area where there are a lot of junk items. The large search head should be used only if the soil of the detection area is homogeneous, free of junk items in the surface stratum and the target to be detected is buried deeply.

Operating the detector is similar to detecting a mine, operator holds the handle of detector and moves the search head slowly along the ground. While searching, the distance between search head and ground should be about 20cm. When a target is detected, the detector will sound and meter needle will move to one side.

Note:

1. After you detects a metal object, move the search head far away from the metal object, and then press and release the push button before proceeding.
2. If you select the "Setting" position, once a target is found the signal sound will die away gradually and meter needle will also come back to zero point slowly. Therefore, the search head shouldn't stay over the target too long. In order to confirm the target, operator can move the search head away from the target, press and release the push button and then detect it once more.
3. Metal objects carried with operator may affect detection. Before searching, operator should remove any watch, ring, jewelry, metal belt buckle, and so on. Operator can't wear leather shoes with nails. It is recommended to wear cloth shoes or plastic shoes.
4. When moving along ground, the search head should be parallel to the ground.
5. Before adjusting any knob of the control box, always press and hold down the push button. After the adjustment is finished, release the button.
   
   

1. Ground Balance Mode

Move the operate mode selector switch to ground balance position to set the detector in the ground balance operate mode. The ground balance mode can eliminate the effect of ground mineralization and has adequate see-through capability. Therefore, it is often the first choice mode for both indoor and outdoor detections. Only after some metal had been discovered, should the discrimination mode be used to identify the kind of the metal.

In ground balance mode the detector will sound and meter needle will deviate from zero point as soon as the search head Is moved over any kind of metal target.
Operation instruction for ground balance mode:

1. Connect the storage battery to the detector.
2. Turn on the power switches of the storage battery and the detector.
3. Move the operate mode selector switch to ground balance position.
4. Lift the search head about 60cm from ground, let the detector preheat for a moment. If the meter needle returns to "0" and no longer deviates after you press and release the push button, you can proceed.
5. Adjust the Tuner knob until the "Critical Sound" is being heard.
6. Using the method described in the Step c and Step d of the section of " The adjustment procedure of the ground balance knob " adjust the ground balance knob until the "Critical Sound" remains basically unchanged when you lift and lower the search head.
7. Search head should be moved along the ground in smooth even swings, and note to keep a distance of about 20cm between the search head and ground.

2. Discrimination Mode

The mode can distinguish ferrous metal from nonferrous metal and also can eliminate the small metal object so as to choose the large one in the same kind of metal. The mode has no function of ground balance, operator must be prudent in using.

Operation instruction for this mode:

1. Turn on the power switches.
2. Move the operate mode selector switch to Discrimination position.
3. Preheating.
4. Adjust the Tuner knob until the "Critical Sound" is being heard.
5. To distinguish between ferrous metal and nonferrous metal:
   Set the discrimination knob to the left of "2", ferrous metals (iron, steel) will make the critical sound increase, nonferrous metals (gold, silver, copper aluminum ) will make the critical sound decrease. If the knob is set to the
   right of "7", nonferrous metals will make the critical sound increase, and ferrous metals will make the critical sound decrease. If the target identified is a plate of iron, when the search head is moved close to its edge, the response would be the same as the ferrous, however, after the search head has been moved over it, the response would be like the nonferrous.
6. To eliminate the targets undesired: If the place to be detected is indoor or ruins, there must be a lot of miscellaneous abandoned metal items there. Generally they are useless, and should be eliminated during detection. For example, when user searches on an area where a lot of waste nails exist, the nails' signals are heard from place to place, consequently, detecting target metal is very difficult. In this case user can put a nail on the ground, then let the search head pass over the nail. If the Critical Sound increase, press and hold down the push button, turn the discrimination knob slightly towards right (clockwise), release the push button and move the search head over the nail again. Repeat the procedure until the Critical Sound is unchanged when the search head moves through the nail. Now the detector will no longer respond to the buried nails and the ferrous metal objects smaller than the nail, but all the nonferrous metal objects and ferrous metal objects larger than the nail will make the detector sound.

3. Practical Example

We have described two operate modes. In actual detection operator should select a mode according to the specific circumstance. Sometimes it is necessary to use the two modes alternatively.
For example, you want to hunt an old house for the deeply buried things left behind by predecessors, there must be a lot of various abandoned scraps (such as nails, wire, scraps of iron pot and so on) in the ground. Generally these things are buried near surface, and so their signals are strong. In order to eliminate these waste objects while detecting the deeply buried target, which mode should be selected? It depends on the accuracy of the information of the target. If it is merely said that there might be something buried there, but you are not sure, you may use discrimination mode, set the discrimination knob at the point where nail is eliminated, then sweep along the ground grossly. When the search head moves above a ferrous metal object bigger than a nail or moves above a nonferrous metal object, the detector will sound out, but this mode can't eliminate the effect of mineralized soil and so the result of detecting is not very accurate.
If you are very sure that something you want is under the ground, the ground balance mode must be used. First of all, you should remove all metal furniture out of the room, then equip the detector with the small search head, slightly decrease sensitivity and carefully set ground balance knob. Whenever a metal object is found during detection, it must be dug out and in this way most miscellaneous waste metal things in the surface will be taken away. After the surface has been cleared, you can replace the small search head with the large one to search toward depth.
Detection is a careful and difficult work. It is necessary for user to be patient, confident and perseverant. No detector can indicate all the buried metal objects perfectly clearly, it can merely predict the target's most likely position. To pinpoint desired target accurately, it is necessary for operator to have rich experiences and the ability to make right judgment on the basis of analysis of the detector's response.

Prospecting

Nugget hunting, which is like coin hunting, is done with the ground balance mode. Most gold is found in heavily mineralized areas, so ground balance must be adjusted carefully in advance.
Alluvial gold ore is a mixture of fine grit nugget or flour gold and sandy soil. It is always accompanied with the deposit of heavy metal ore. The signal produced from the mixture is like that from ferrous metal, however, the mixture's response is weaker and give the response over a much large area.
The detector can also be used to select ore: lay the detector on a non-metal support, adjust it for the critical sound, then bring each of ore samples toward the search head and determine its content according to the intensity of audio signal. Always remember to press and release the push button after an ore sample is tested. The technique of measuring metal content is very useful for the selection of vein gold ore or measurement of tailings left in old mine. Some miners take the ores that contain visible gold and ignore the rest. In fact some of the abandoned ores still contain gold.
For other kinds of ores, some signals are strong, some signals are weak. Operator can use a standard ore sample to test, notice how the signal is like so that the difference of signal between the ore and ordinary rock can be known.
