There are a large number of coils of different shapes and sizes available in the market. Choosing the right coil depends on the environment in which it is used, as well as the type and material of the desired target. Any change in the above factors can cause the expected coil to change.
In general, the coils are either circular or elliptical; Elliptical coils are more maneuverable than circular ones and their narrow width gives better coverage than circular coils and the reason is their longer length.
Small Searchcoils
Because the magnetic field produced by small coils is more concentrated, they can be the best choice for exploring fields with high amounts of metal waste. These coils allow more maneuverability around metal debris to find suitable targets. You can also use these small coils in tight places and cracks in the ground where it is not possible to use large coils. These loops are the best choice for small targets, but small coils cover less ground per turn and require more time to fully explore a certain amount of ground.
Medium Searchcoils
These search coils are used for various types of exploration, including coin finding, treasure hunting, industrial uses, etc. Because these coils are a suitable combination of size and concentration of the magnetic field and depth of exploration and are compatible with most metal detectors, they are a suitable choice for various types of work. In addition, these coils have a light weight that makes their transportation very simple.
Large Searchcoils
The larger the metal detector coil is, the bigger and deeper the magnetic field is, and they cover a wider area during exploration, which makes it possible to scan a specific environment in a shorter period of time, although this factor is a bit troublesome in more polluted areas because the coil It covers several purposes at once.
