The Tips for Choosing Metal Detector

The Tips for Choosing Metal Detector Overview

On the market, whether domestic or imported detectors, brands, or models are emerging endlessly, they have reached a saturated state. For new players, there are too many choices, which means that it is very possible to choose a detector that is not suitable for you. So how do you choose a machine that suits you and is cost-effective?

First of all, you have to understand that metal detectors can approximate the depth of the target object based on the strength of the magnetic field generated by the target object. And most metals have different conductance and resistance values. Metal detectors can use a pair of electronic circuits called phase demodulators to measure the phase shift and compare the measured data with the average phase shift of a certain type of metal. Then the detector will inform the detector of the metal type range where the target object may be in the form of an auditory or visual signal.

Secondly, let’s judge whether the metal detectors on the market are good or bad. To be precise, we should be judged the advantages and disadvantages, because any detector can achieve the detection effect, but as an explorer player, we are pursuing deep and deep Detectors with good discrimination ability. It is recommended to evaluate from the following points, as follows

Detection depth

Detection depth is one of the most important points of metal detectors.  some unscrupulous merchants deliberately exaggerate their performance in order to sell products better, saying that it can detect more than ten meters, which is impossible. All friends and players must recognize and don’t be deceived by false propaganda. With the current level of technology, underground metal detectors can detect 5 meters, which is already very impressive.

Working frequency and frequency shift

The working frequency of the detector, that is, the number of electromagnetic waves emitted per second, for a simple analogy, is similar to the long punch and the short punch in boxing. The short punch is fast, the distance is short, and the density is large; Long fist, slow speed. Therefore, the low-frequency probes deep and large objects, and the high-frequency probes fine and small objects. To give you some reference values, silver dollar detection is suitable for low frequencies; copper coins and copper miscellaneous parts are suitable for 10-20khz; smaller objects are suitable for more than 20khz.

Detection mode

At present, most metal detectors on the market have multiple detection modes. Depending on the number of detection modes, the price will vary. Some detectors have as many as nine detection modes, such as ANFIBIO: full metal, 2 tones, 3 tones, 4 tones, 5 tones, 99 tones, beach, depth, cellar. In this way, different modes can be selected according to different environments.

Ground balance adjustment

It adjusts the internal reference value of the detector to make it better adapt to the soil with different degrees of mineralization. That is, the detector will give an alarm when it encounters the target metal. When it encounters objects such as junk metal or surface minerals, the detector should not give an alarm. For a good underground metal detector, the ability to adjust the ground balance is a crucial condition. The ground balance is not well adjusted, and all metals are murmured, and no matter how deep it is, it is garbage metal.

Probe size

the larger the probe, the better, it should be selected according to the actual needs of the probe. The small probe is more sensitive to small metals, and it also ensures the depth of large metals. The depth performance is very balanced. The unique coil arrangement ensures fast response speed and improves the positioning accuracy of the machine. In places where the degree of soil mineralization is low, there is little garbage, and the land is open, the large exploration disk can explore deeper and cover a wider area, which can greatly increase work efficiency and take less time to complete the exploration.

Gap filtering

Supports setting multiple ignore intervals. By setting the metal detector, let it ignore objects in the phase shift interval with the can pull ring or small nail. This function is also extremely useful for finding a specific type of target.

Finally, you need to determine your spending power, that is, what your budget is, and then choose a more cost-effective detector at the same price. For novice players, it is recommended to choose from about three thousand entry machines. Xingbaolai is good, with enough functions and easy to use, and the price is very reasonable.

Many explorers asked me about my detection experience. In fact, because of different environments such as soil, my detection experience may not be suitable for you. I should dig more and carefully analyze the value and sound of the detector. Over time, it will surely accumulate more applications. Based on my own experience.

Above, if you understand these well, then choose the detector that suits you, rather than everyone else.
