EPX-9900 Remote Underground Metal Detector

Introduction of molecular frequency scanning:

The inventor of molecular frequency scanning is John Fells from Florida. Mr. Fells is highly respected in archaeology and professional treasure hunting. Mr FALES's achievement is to design an instrument that communicates with other components according to its own molecular frequency. Because of this achievement, he was called "Farce effect" by the industry.

Mr FALES and some close colleagues began to develop this instrument in 1960. The research team has two goals. The first main goal is to design an instrument to find a specific element in the periodic table and distinguish it from other elements. The second goal is that the instrument indicates the target to the user through traceable signals.

The first major goal has been achieved, and the result is quite encouraging. The designed instrument can detect buried targets at a considerable distance. The second goal has also been achieved, because the instrument can indeed establish a detectable transmission line to reach the target.

Since it came out in 1980s, many improvements have been made. At present, the conservative range of all models is 1/2 miles, and the selected frequency can be transmitted in all directions.

In order to explain the basic concept of EPX9900 scanner, we must first understand some very important facts. John Fells and his colleagues spent thousands of hours experimenting with a large number of theories and hypotheses. Densification experiments were carried out on electromagnetic induction, radio frequency and gamma wave transmission instruments. I learned a lot about the electromagnetic effect and ionization effect at all stages of matter. When developing the original scanner, a lot of knowledge I learned was applied to it. What is really unique is that the scanner can use air, soil or water as the transmission medium. It can not only transmit signals horizontally, but also vertically. One can imagine that in the center of the 3/4 foot range, this is a possible target area.

Once the scanner signals, possible targets will respond with the same signal. Because the signals are the same, the scanner only tracks the responding targets, thus eliminating the situation of tracking unnecessary targets.

The mutual recognition signal between the scanner and the target becomes a traceable route, through which the operator can determine the position of the target. It takes several minutes to determine whether there are any suitable targets within the normal operating range of the scanner. Remember, the range depends on the size of the buried target, the length of time in the ground, the electrolyte in the transmission medium, and strong sunlight activities such as sunlight and strong sunspots. Because the natural attribute of the signal is frequency, strong sunlight activity will greatly weaken the signal.

All elements in the periodic table have a natural phenomenon of * * * vibration. This is the ability of an element or object to absorb energy and produce vibration at its natural frequency. A simple example is that a trumpeter can break glass by playing a cheerful, exciting and high-pitched piece of music. If the natural frequency of the glass is the same as the frequency of playing music, the glass will start to vibrate. In addition, if the vibration intensity reaches the crystal structure, the glass will eventually break. When an element absorbs energy at its natural frequency, it vibrates. When the emitted frequency is easily absorbed by the same object, this * * * vibration phenomenon will occur. If two objects have the same structure, the second object will naturally cause oscillation.

So you should have a clearer understanding of the guiding theory of EPX9900 scanner. Please note that it took us 30 years of research work to get today's EPX9900 scanner. Thanks to the contribution of EPX9900 scanner and JOHN FALES, there are some instruments that can distinguish specific underground elements today.

Second, the working principle:

Before the transmitter was developed, it took many years to test various theories, ideas and equipment. It is small in size and powerful, and can transmit radio frequency signals remotely through soil. Signal 360? Introduce soil in all directions. It is because of this inductive energy that the target can be seen. The signal sent by the scanner enters the ground through the power sensor. If the target is within range, the signal is absorbed by the target. Insert the indicator stick into the power amplifier to complete the receiver circuit. The circuit consists of the human body capacitance of the operator and the inductance element of the power module. The circuit will play an active role when the operator walks through the transmission line between the scanner and the target. The induced RF energy from the transmission line interacts with the circuit inductance and capacitance of the operator. At this point, the normal reaction is that the indicator sticks attract each other. This is actually a message to the operator that the target is within the range of the scanner. The range of the scanner varies with many factors. The first and most important variable is the target size. Followed by soil conditions (the existence of electrolyte) and the length of underground time. Another factor is the chemical change of the soil around the target, which can enhance the operating performance of the scanner. For the target that is easy to be oxidized, whether it is the object itself or its container, it will send a stronger signal. Due to the oxidation factor, the target amplification scanner will have greater potential to transmit signals.

Third, the frequency selection:

The frequency of EPX9900 scanner is set for a specific purpose before leaving the factory. There is no guarantee to change the settings of the instrument.

1, detection, first adjust to the required detection mode, and then adjust the frequency to the minimum frequency value reflected by the geographical environment at that time for detection; 2. Because the geological mineralization reaction of geological bodies in each environment is different, such as gold, silver, copper, pyrite, iron ore, lead and zinc, ore, limestone fissure water, bedrock fissure water, etc. When selecting the frequency, the detection should start from the minimum frequency. If the intensity of mineralization interference is large, the middle average value can be selected for detection, and the best and appropriate detection frequency can be selected.

note:

Never use alternating current to power the scanner. Do not use 1 10 VAC or 220 VAC to power the scanner. This will cause permanent damage to the instrument! Therefore, such damage is not covered by the instrument warranty.

GG777 Golden King Detector

I. Introduction:

The best underground metal detector in the world-GG 777. Jinke GG777 Gold King Detector is an underground metal gold detector developed by China people. It adopts MPS, DVT and SETA high and new technologies. This product consists of a main machine, a probe disk, a probe rod and an armrest, and is packed in two pressure-resistant boxes inside and outside. Chinese and English menu operation on high-definition LCD screen is easy to operate and carry. This product is deliberately exquisite in design and adopts high-quality imported parts. It has the advantages of deep detection, simple operation, accurate positioning, strong resolution and high efficiency of gold identification, which is beyond the reach of GPX and Garrett. It is not only suitable for archaeological treasure hunting, but also has the effect of finding gold nuggets in placer gold mines. This product is supervised by Jinke International Security Inspection Holding Group. Second, the characteristics:

1 and D-type coils are used to eliminate mineralization. When using old metal detectors, the most annoying problem is the influence of the ground. With the change of the distance between the probe and the ground, the signal of the instrument also changes. If the probe sweeps across the uneven ground, the change will be even greater. The operator seems to hear the signal everywhere and can't figure out where the metal is buried. This phenomenon is called "mineralization reaction". The reason why "mineralization reaction" occurs is that various minerals that make up the soil make the instrument send out signals. Where the soil structure is complex, the "mineralization reaction" is very strong, and the signal it causes is bigger than the metal signal. At this time, it is difficult for operators to judge whether the signal is buried by metal or "mineralization reaction". GG777 is equipped with ground balance circuit, which can eliminate all the effects of "mineralization reaction". Only when the probe meets the metal you choose (optional gold, silver and mixed) will the detection depth and accuracy be greatly improved. 2, pressure-resistant packaging is easy to carry and transport, waterproof and moisture-proof. 3.SETA technology can improve and maintain the stability of detector response threshold through SETA compensation measures for dynamic noise, which can make your GG777 always in a high efficiency state under all working conditions.
