  • Metal detector using coils with multiple detection zones to identify targets while moving
    Publication number: 20170235009
    Abstract: A metal detector with multiple detection zones of alternating polarity achieved by means of multiple coil windings such that when a target moves across it, a detection signal of alternating polarity is generated with a waveform shape which replicates the pattern of zones, a distinctive detection waveform which enables enhanced recognition of target presence while in motion. Balance to external EMI enables the use of large coils for non-swinging searching at high area searching rates.
