Magnetometers are to detect archeological sites, shipwrecks and other buried or submerged objects. To survey a large area a towable magnetometer is used such as the Proton 5 Magnetometer or the Pulse 10 or 12 Metal Detectors for non-ferrous metals. In researching more localized areas hand-held magnetometers or metal detectors are very useful such as the Diver Mag1 or the SAR-1 metal detector for non-ferrous metals. Sea-View Diving has a great selection of high-quality metal detectors by JW Fisher Manufacturing.
Boat Towed Metal Detectors
Pulse 12 Metal Detector
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 3 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.
Pulse 10 Metal Detector
With its 12 foot wide and 8-foot deep detection envelope his detector will locate a variety of targets including aluminum boats, brass propellers, outboard motors, steel anchors, bronze cannons, and gold bars.
Boat Towed Magnetometer
Proton 5 Magnetometer
The PROTON 5 is a fifth-generation proton magnetometer from JW Fishers. It is a top performing microprocessor driven marine magnetometer detection system. The Proton 5 definitive detector for iron and steel targets. Its maximum range capability of 1,500 feet (450m) on each side (3,000-foot total swath) lets you search a wide area quickly and completely.
