This device will be indispensable in cases where you need to maximize the search depth of objects. The main purpose can be called the search for large-sized metal objects. The coil is compatible with multi-frequency metal detectors of many series. This device is able to detect even coins of five Catherine kopecks at a depth of 60 centimeters. The coil is quite calm, behaves well on moist soil, quickly identifies large targets. Many experts say that it copes with the search for wartime items even at a depth of one and a half meters. The device should be handled more carefully, it does not tolerate blows and shaking. It should be noted again a highly sensitive sensor that perfectly copes with the amount of its work. The round shape is very comfortable. Low frequency increases working depth.
Disadvantages of the coil:
1. Poor performance in littered areas.
2. Poorly searching for objects of small sizes. Only if the target lies completely on the surface.
Advantages of the coil:
1. Increasing the depth of finding targets.
2. A low level of frequency increases the probability of finding large objects made of metals. Used to search for treasures and items of the Second World War
