The diameter of this coil allows you to search for targets in very heavily littered areas. Compared to the 6 and 7 kHz coil , the search depth is slightly less. Easily pulls out all useful targets lying on the surface. The frequency of 14 kilohertz does not catch the rusty iron located deep in the ground, and thereby accurately displays information on the hodograph about a target lying almost on the surface. The small diameter of the coil accurately divides the targets on the surface. For example, a small coin and a rusty nail lying nearby.
Disadvantage of the coil:
1 A small depth of search, which, however, is a huge plus when searching in littered areas.
Advantages of the coil:
1. Good sensitivity to small targets.
2. It is convenient to conduct searches in tall grass and places with limited access, for example, attics of houses, cellars, corners of a building, etc.
