About a hundred years ago, the first metal detectors were used for utilitarian purposes. They stood at the exits of factories to prevent workers from taking tools out. The subsequent development of technology has made metal detectors much more compact and more sensitive. Modern models can find a coin at a depth of up to 50 centimeters. The scope of the useful tool has expanded.
What modern models of metal detectors are capable of
Depending on the design and sensitivity, all devices capable of searching for metal are divided into several categories. Household, the simplest, are used for lost jewelry or metal objects in nature, a public beach. Industrial products are the most sensitive. For the military, a metal detector is produced specifically for searching for explosive objects. Individual characteristics worth highlighting:
- the ability to distinguish between non-ferrous and ferrous metals;
- to see the contours of the object at a depth, in the ground;
- the area of the scanned territory of devices;
- compact and easy to use;
- autonomy, how long one battery charge lasts.
It makes no sense to buy a powerful, industrial model of equipment if it will be used only for domestic purposes. And vice versa, a simple analogue will obviously not be enough for the needs of the industry. New ones are produced every year. More sensitive and powerful metal detectors.
Main scope
Manufacturers of metal detectors have made a lot of models designed for various search conditions. It is impossible to make one, universal device that will cope equally well with different tasks. The most popular and sought-after destinations are the following:
- To search for metal objects in the human body (medicine).
- For conveyor lines for detecting metal in food.
- Special checkpoint for screening people.
- Search for archaeological treasures in the ground.
- Detection of metal in the walls and ceilings of buildings.
Important: the Medvejatnik Lockmaster Store metal detector showed particular popularity in the field of detecting metals in the ground and archaeological values. Depending on the type of electromagnetic coil, the device is able to identify even the smallest objects, the size of a small coin or a large metal pin. Including those made of precious metals.
