Police departments & sheriff’s offices around the country are adding underwater metal detectors (UMD) to their crime-fighting armory.

Many marine service companies are acquiring boat-towed metal detectors and magnetometers to assist in salvage operations and geophysical surveys. These devices can locate a variety of targets including sunken vessels, ship anchors and propellers, pipelines, cables and metal debris which must be removed from an area before dredging. The two primary pieces of equipment used in these operations are a magnetometer and the pulse induction (PI) metal detector. Magnetometers are super sensitive instruments that can detect iron and steel objects at hundreds of feet away.

New Technology for Subsea Pipe and Cable Tracking

Utility companies have been laying pipes and cables across the ocean floor for more than a century. Prior to the introduction of GPS, marking their location was difficult, and position information was often erroneous. It is extremely important to know where existing lines lie before undertaking dredging operations or when new pipes and cables are laid down. Regulations require they be buried from several feet to several meters under the bottom to prevent snagging by anchors and…

A number of archaeological groups and marine service companies are acquiring boat-towed metal detectors to assist in locating shipwrecks and to perform geophysical surveys. These devices can locate a variety of targets including the piles of magnetic ballast stones found on many old wrecks, gold and silver bars, cannons, anchors, pipelines, cables, and various metal debris which must be removed from an area before dredging. The two primary pieces of equipment used in these operations are a magnetometer and pulse induction (PI) metal detectors.
