In relation to metal detectors, there is a fierce competition in the global market, and this competition has caused the companies that have production permission to express favorable conditions of real materials so that the production and sales market does not deviate from the buyer’s expectations.
Because the competition in this field is tight, in order to avoid false conditions in the market, those reliable factories and companies that have permission and certification, design, manufacture, manufacture and sell professional metal detectors or professional hand-held ground radar with VDA number in the world and Their number is a handful.
Among themselves, they have set certain conditions to refrain from presenting content that is contrary to reality, and to state the facts and not to express unreal content, and since metal detectors are relative conditions, it is not possible to automatically confirm 100% detection in relation to the way the metal detector works. provided these devices.
The same relativity in the performance of a metal detector or manual ground radar, especially in their professional type, which separates the ability of the operator or user in precise operations, should be taken into consideration.
Characteristics of a good metal detector
One of the characteristics of a good metal detector is the use of a sensitivity and meter indicator, so long as it is used as a gold detector, it shows a good sensitivity to the metals found deep in the ground, and this sensitivity is displayed on the device. Notify the user. Also, having high portability and good frequency change are important features of a professional metal detector, which we will explain each of them below.
High portability
One of the most important features of the device models available in the market is its weight and dimensions. The more appropriate the dimensions and weight of the metal detector, the more portable it is and the easier it is to maintain.
Due to the fact that these devices are usually carried by people on difficult routes, its appropriate weight and dimensions can increase the efficiency of the device and its use in mountain routes where the probability of finding gold and precious metals is higher. make it easier
Frequency change
Another feature of the metal detector that can be used as a gold detector is the possibility of changing the frequency. Considering that in places with soft soil, it is necessary to search and explore more deeply, it is necessary to increase the frequency of the device.
Meanwhile, in environments with hard rocks, in order to increase the penetrability of the gold detector device, it is better to have a low frequency of the device so that it can easily pass through hard obstacles and bring people closer to their desired goals. Of course, the most important The factor in determining the price of a metal detector can be considered the possibility of removing unwanted particles.
Important indicators and features of a metal detector
- As mentioned, in general, a professional metal detector has the following features:
- A good metal detector should have a penetration depth of at least 3 meters.
- have a sensitivity indicator and a meter.
- Light and compact.
- It has the ability to change the frequency.
- Separation should be at least 50%.
- It is possible to remove at least 50% of unwanted particles.
- have a manual balance. If the balance is not manual and automatic, the depth of penetration will be less.
- It has the ability to separate iron and non-iron, or even the new type of separation, that is, Just Gold (only gold).
- It has VLF and PI working system and best of all modified PI working system which is a combination of two types of VLF and PI working system.
- Get a metal detector that the seller will fully test the device in the land and place you want and of course in any type of soil and deliver it with a reliable guarantee.
