Pulse Induction Metal Detector SDP 2014 A

        Tired of digging trash! "The Discriminator" SDP-2014A is a new generation pulse induction metal detecting instrument, with discrimination, for locating large and middle sized targets (6" & larger) at greater depths. This pulse induction system is developed to retune automatically to ground mineralization changes and to the slowly changing external electromagnetic fields. The Discriminator has a built in Magnetometer to discriminate Ferrous metals, indicated by a red LED. Penetration is a unique combination of pulse induction technology, greater detection depths compared to any other metal detector sold on the market, with smooth stable operation through its automatic motion mode.

        The search coil sends out short magnetic pulses. The magnetic field induces eddy currents in the metal objects to be detected. These currents generate a secondary electromagnetic field which flows outward from the target. A portion of this secondary field passes through the antenna winding. This signal is processed by the electronics and displayed by a ticking rate and meter response. The timely decoupling between the transmitting and receiving phases allows the Discriminator to work with greater transmitting power. The Discriminator automatically keeps its maximum sensitivity and detection depth for gold, silver and other highly conductive royal metal targets.
