You basically cannot detect places with open mouths with a detector. Deep search detector models can detect underground, closed, airtight, naturally formed or artificially formed cavities within the detection distance. As with metal, it affects the depth of space in the soil structure. At the detection distance but not large enough to detect, then the detector will not be able to see the gap again. The larger the gap, the more deeply it can be detected. If the gap is not within the detection range, it will naturally not be detected by the detector. You can detect gaps with the detector.
There are different depth tests that we perform in deep search detectors, and the final test is 350cm in the form of 1, 2, 3 meters. There are different depth tests we do for deep search detectors, but of course depending on the depth logic. As the metal grows, you can detect from the depth, and as it gets smaller, you can detect it from the surface. Depths vary according to the size of the metal, its type, the duration of being under the ground, and the soil structure. We often hear from you the question of whether the detector goes deep.
Detector models are produced according to different usage areas. Deep search detector models, on the other hand, are not suitable for small metal prospecting. Detector models produced for surface metal detection are used for ring, earring, necklace, single coin and relic search. It is used to detect larger metal targets at deeper depths.
Detector systems are divided into VLF and Pulse. Even if a user says to buy a VLF detector and use it everywhere, it will not work. When the advantages/disadvantages between the systems are examined, it is seen that the most used system in the world is VLF. The user has to choose between the detectors recommended to him according to the features and usage area.
