When using the coil, which has a high thickness of wire TX (quality)-the depth of detection increases by 1.5 - 2 times compared to Lobo ST.
He also sees fine objects and thin coins vertically. It is Characterized by stability, does not depend on temperature, works in wet ground, is not susceptible to interference.
