Pulse 12

Fisher's powerful boat-towed metal detector searches for ferrous and non-ferrous metals.

With its 24-foot-wide and 16-foot-deep detection envelope, this detector will locate a variety of targets, including aluminum boats, brass propellers, outboard motors, steel anchors, bronze cannons, and gold bars. One of the key features of this detector is the control unit, which can accept inputs from three search coils. Using three coils instead of one lets the search team cover three times the area with the same amount of time, fuel, and manpower.

The claim-to-fame of this pulse induction metal detector is its ability to ignore minerals in the environment while maintaining high sensitivity to all metal targets. The Pulse 12 is not affected by highly mineralized salt water, coral, high iron content rocks, or magnetic (black) sand, all of which cause erratic readings in conventional detectors. Also, the detection range is unaffected by the medium between the metal detector and the metal target. Performance does not change whether detected through air, water, silt, sand, or solid coral. See the technical data sheet for actual detection distances.

The Pulse 12 system includes a 24 by 36-inch search coil with 150 feet of cable, tow fish, and a top-side control unit. The control unit features three sets of operator controls, which allow up to three coils to be towed simultaneously. Both meter and audio readouts indicate target detection from each coil. Options include cable lengths up to 500 feet, UA-2 altimeter, USB data output interface, Tracker software, and DDW-1 deep dive wing. The USB data output allows the Pulse 12 readout data and GPS position coordinates to be displayed and stored on a computer. Two 12-volt batteries power the system with a total power consumption of only 12 watts.

An optional Microsoft Surface® tablet can be mounted in the control box lid, eliminating the need for a separate laptop computer, making it a "sleeker" package.

Optional Tracker 3 software shows the boat's path as it moves over the search area. It includes a cascading waterfall of the Pulse 12 readouts and the GPS position associated with each readout. When a target is detected, the readouts and coordinates change color so the operator can quickly see when and where a target is detected. At the bottom left of the screen is a graphical representation of the last 1 minute to 1 hour of Pulse 12 readouts. When a target is detected, the line swings up on the graph. In addition to the Pulse 12 and GPS data, the boat's speed, compass heading, and alarm setting are other information displayed. Up to three fish can be displayed on the screen.

The Pulse 12 is in use by military, law enforcement, commercial, and salvage divers world wide. High sensitivity and a very large detection area make this detector an excellent choice for both commercial operations and professional treasure hunters.

The Tracker map can be exported as an image with a KML file to be easily overlaid on other mapping programs. All data can be stored on the PC hard drive or disk.
