Classification of metal detector based on frequency, Generally speaking, the frequency of a metal detector is one technical characteristic of the device, that directly affect the effective search. So the idea is to compare the devices on this crucial indicator is not new and attached metal detectors constantly found the comparison of different devices on that parameter. treble well discover big goals at great depths, and high frequencies are better suited to search for small objects at shallow depth.

There are devices that lead to search simultaneously on multiple frequencies. Obviously its devices of the highest class. There are devices that can search on different frequencies, but for this they need to install another reel. the bulk of the instrument leads search for fixed frequency. Some are higher class have the option of manual setting of the frequency in small limits, example Garrett AT PRO.

High frequency of 18 kHz allows you to capture small objects the size of 1-2 mm. However, the high-frequency signal decays faster in soil, so the depth revealed facet slightly less.
Low frequency 3 kHz worst detect small objects, but electromagnetic waves deeper into deep penetration under higher detection objects. Low operating frequency, and the deepest detector can detect the target.

It uses a single 4093 quad Schmitt NAND IC and a search coil. A lead from IC needs to be attached to a MW radio aerial, or should be wrapped around the radio.
