Handheld metal detector with enhanced and adjustable detection power

Abstract

The invention relates to a portable metal detector (20) with increased detection power by the addition of a power converter (25). The power converter (25) is remote from the detection disc (22) and in particular from the member for capturing electrical disturbances of the electromagnetic field produced by the transmitting coil(s) (220). This remote location makes it possible in particular to prevent the working frequency of the power converter (25) from producing disturbances in the signal captured by the capture member.
