Handheld Underground Metal Copper Detector
Copper (locating copper coins), Gold (measuring gold), Silver (measuring silver dollars), Diam (measuring jade and gemstones)
An excellent gold, silver, copper, and emerald search instrument. It is manufactured using American gold prospecting technology. The sensitivity and stability of this treasure detector are at the highest level of similar international products. In addition to the above features, another most prominent feature of this treasure hunter is that it can directly select the type of metal and directly detect the metal you want to find; it makes it easier for you to find metal objects, which is a function that other similar domestic products do not have. With this detector, you can go to more places to carry out treasure hunting activities and search for the gold, silver, copper, and gems you want to find.
This instrument perfectly combines field archaeology and scientific theory. The American Black Hawk metal detector uses the original American Black Hawk microprocessor. This type of long-range detector is specially tuned to the recognition function. Looking for precious metals and porcelain jade at long distances and great depths, this lightweight device will provide the greatest degree of performance. The treasure hunting and prospecting functions are very excellent, with a built-in scanning rate adjustment function, the detection is more targeted and accurate, and the detection adaptation function can quickly find the target.

Operation method
1. First turn on the power switches of the receiver and transmitter, and then select the metal category according to the gear on the receiver. For example, gold, press the gold gear, and the gold light of the receiver will light up at the same time. Then take a key in front of the receiver and place it for about 10 seconds to demagnetize. Then put the metal to be detected on the head of the receiver to adapt for more accurate detection. Because the handle of the instrument will rotate freely, the wind will interfere with the Black Hawk metal detector. Therefore, the instrument will be interfered with when used in windy conditions. The use effect of this instrument is closely related to the operator's control skills for scanning. Choose a comfortable posture to stand on the ground, hold the instrument with your hands, and keep your elbows tightly against the sides of your body.
Note: You must keep the instrument in front of your body, so that the receiving antenna has enough space to unfold, and the antenna is slightly tilted downward from the horizontal line. This angle is about 7 to 10 degrees.
(1) As mentioned above, hold the instrument and scan very slowly in an arc while turning yourself. At this time, the detector's elbows should always be tightly against the sides of the body. Turn about 40 to 60 degrees. Note: The detector must rotate slowly and keep the body and the machine stable.
(2) Standardize your scanning action. First, let the receiving antenna extend correctly. Make the receiving antenna directly in front of you, 90 degrees to the body, and cannot deviate to the left or right.
(3) When the antenna is aimed at the target, the instrument will lock, even if you continue to detect across the target. When you feel that this lock is effective, remember this direction. Then, move the instrument to the left or right about 10 meters and repeat the process of locking the target just mentioned. Observe the locking direction this time. The intersection of the two directions is the buried location of the target.
(4) If you feel that the specific location just measured is still offset, you can lock from another angle. If the target is within about 10 meters, you walk slowly and steadily along one of the designated routes. When you pass the target and are directly above it, the antenna of the instrument will swing from side to side. At this time, the measured position is very accurate.
2. Introduction to auxiliary detection methods
Box method: It is recommended to use the box method to narrow the search range. This method can locate as accurately as possible. Approach the target from four directions to obtain accurate and equal responses to accurately locate the target.
First place the target on the ground, then you can learn to adjust this product to point in the direction of the target. Therefore, a skilled operator usually sets a sample target, walks over the target placed on the ground, observes the hit rate, and adjusts the instrument, and then continues to search parallel to the area after narrowing the target range with the cross method.
Once you follow this step, you can narrow the area to equal to or less than 20 feet. Then you can use a regular metal detector to complete the work. Some people who are quite proficient in the use of this product can almost accurately locate the target point to the foot. To achieve this level, it is recommended that you practice diligently.
When searching the target area using this method, stand in the front of the area and scan. The detector will show whether the substance or material being searched is in the left or right half of the area.
If the detection is performed in the right half of the area, move to the center of this part and scan again. With the second detection, the trained operator can determine the location of the material in a quarter circle, left or right half, vertically dividing the area.
Safety Warning:
1) Make sure the battery is fully charged, low battery will not work properly.
2) Make sure the instrument rotates 360 degrees horizontally normally.
3) The height of the instrument should not exceed the shoulder or neck.
4) Do not throw the instrument hard! Keep away from fire, water and corrosive chemicals. Rough handling of the instrument will reduce sensitivity or even damage it.
5) After using the instrument, turn off the power and put it back in the tool box.
Notes:
1. General Equipment Rules: As an electronic device, the Black Hawk Metal Detector must be treated with caution. When using such a device. Any failure to comply with safety precautions or any use, out of consideration for its purpose, may cause damage or destruction. Processing unit and connected components, if not opened correctly, the device will be destroyed.
2. Possible health hazards: If used properly, the device does not usually cause any health hazards. According to current scientific knowledge, high-frequency signals are harmless to humans, indicating their low power.
3. Surrounding areas: When moving from cold areas to warmer places, the device should not be operated, immediately followed by any condensation that may form, which may lead to the device being destroyed. Avoid strong magnetic fields, which may occur in the vicinity. Various factors that interfere with the signal (signal towers, high-voltage lines, powered devices, switched-on mobile phones), avoid using the detector within a radius of 50 meters.
4. Supply voltage: The power supply should not exceed the indicated value range. Use only the charger, the battery is included in the scope of delivery.
