JW Fisher top of the line boat towed pulse induction metal detector detects both ferrous (iron/steel) and nonferrous (gold/silver/aluminum/ bronze/etc.) metals. The PULSE 12 is the most powerful towed underwater “all metals” detector on the market today. The system has a huge detection envelope with good detection capabilities in saltwater and even greater range in freshwater or on land. The Pulse 12 comes with a Control Box, a Search Coil with 150 feet of cable, and a Fish. The Search Coil mounts on the Fish and is towed through the water at 1-4 mph. The Control Box has inputs for three Search Coils. Two additional Search Coils can be added at any time and come complete with cable and fish. The additional Coils allow larger areas to be covered. One Fish is towed directly behind the center of the boat, and the other Fish are towed to each side of the boat. One, two, or three Fish can be operating at the same time. When using multiple Fish, each has its own controls and meter on the Control Box. An alarm sounds, and the meter swings up when any of the Search Coils detect a target. Two 12 volt batteries power the complete system. An operator can attach an Altimeter to the Fish to inform the operator of the distance between the Fish and the bottom. Optional Tracker software is available that displays and records all data, including boat tracking.
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 along with 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, other information displayed is the boat’s speed, compass heading, and alarm setting. The controller can display up to three fish on the screen.
The Tracker map can be exported as an image with a KML file to allow it to be easily overlaid on other mapping programs (as shown above). The PC hard drive or disk can store all data.
