Professional and Semi-Professional Metal Detectors

Metal detectors now become indispensable equipment in the reconstruction of old houses, it is with their help that workers search for laid pipes, electric cables, etc. Search for metal objects underground, in water, walls of a building, etc. is not only a method of making money or a hobby for some people. Archaeologists, divers, military have long been using special devices to search for various objects in a neutral environment.

Categories of Metal Detectors

All devices are divided into categories:

  • Entry-level devices;
  • Semi-professional;
  • Professional;
  • Specialized;
  • Underwater.

Thus, the types mixed somewhat with a different approach, and it would be more correct to divide the devices into simple types - entry-level, semi-professional, professional. Everything else can be included in the types of design complexity, features and price. Simple devices allow you to search for metal objects at depths of up to 10-20 (coins) or 60-70 cm (large objects). Most often, you can find videos on Youtube with them. Such detectors suit beginners, since such a device costs up to $200. A typical example is the Garrett Ace 250. Check and you’ll definitely find a detector for you money.

Semi-Professional Detectors

The price immediately starts from 500-1000 dollars. For this money, the device uses several operating frequencies, various types of signal output to the monitor, determines the difference between ferrous and non-ferrous metals. When working exclusively with silver and copper, the device differentiates them very clearly, so for these materials the metal detector can be called professional. It finds coins at a depth of up to 30 cm, larger objects - from 0.5 to 1.5 m.

Professional Detectors

Prices start at $ 1,000 to infinity. Detectors use multi-frequency electromagnetic field generators. The settings of the device make it possible to detect separately a copper coin among a silver bucket at a depth of half a meter, and large objects are detected at a depth of up to two meters. Complex models of detectors can even before digging draw the contour of a found object, estimate its weight, chemical composition using precisely defined tables of electromagnetic permeability.
