Metal Detectors with an elliptical coil
Elliptical
— elongated coils provide a somewhat "stretched" electromagnetic field. On the one hand, this expands the size of the captured area, on the other hand, it somewhat reduces the accuracy. However, all this is true only for concentric coils — elliptical windings of the DD type practically do not differ in performance from their round analogues.elliptical | clear | Save List |
