Abstract: A device for determining amount of deployment of an anchor that includes a sensor assembly, an anchor line, a detector/pulse module, and a digital counter/readout display. The sensor assembly includes a coil assembly that contains metal detecting coils. The anchor line contains a plurality of pairs of pins that are spaced-apart from each other, are in alignment with each other, and cooperate with the metal detecting coils, wherein each pin of each pair of pins is perpendicularly crossed to each other, engage each other, and extend diametrically in the anchor line. The detector/pulse module has an input jack, an output jack, an LED, and an on/off switch. The digital counter/readout display includes a digital display, an automatic sleep mode/wake button, a power/reset ganged button, a fuse, a power jack, and a data jack. The device further includes a metal detector circuit that includes a tuner circuit, and an amplifier pulse shaper.
