Over the last 50 years most ship- wrecks have been found with the help of a magnetometer. These super sen- sitive metal detectors, first used in

WWII to locate and track sub- marines, have become one of the pri- mary underwater search tools for both the salvage industry and the sci- entific community.

Mags sense changes in the earth's magnetic field. Any object made of iron or steel creates a disturbance in the magnetic field. A mag can detect a major disturbance, like the one cre- ated by a steel wreck, at a distance of a quarter-mile or more.

Today, the Proton magnetometer is a workhorse in marine search opera- tion. It is deployed by a diverse group including professional treasure hunters, marine archeologists, com- mercial diving companies, law enforcement agencies, and military units. The proton mag is designed to be a rugged, reliable instrument that is very easy to operate. In addition to finding shipwrecks, mags are often employed to locate pipelines, anchors, sunken automobiles, weapons, and unexploded ordnance.

JW Fishers specializes in the design and manufacture of magnetometers and currently produce two mags; the

Proton 4 boat-towed model and the

Diver Mag 1, a hand-held unit car- ried by a diver. The Proton 4 features an LCD display that is backlit for night operations and an audio alarm to alert the operator when a target is encountered. The Diver Mag 1 has an LED display for easy underwater viewing and a waterproof earphone that lets the diver know a target is being detected.
