Magnetometers – The Life Blood Of Treasure Hunters

Proton Magnetometers

First and foremost in the treasure hunting business is the scuba-equipment then followed by the Magnetometer and when used in conjunction with the side scan sonar they are formidable pair of sensors.

They come large and small, The Proton Magnetometer Commonly called a “mag”, is the tool used in locating ferrous parts of shipwrecks buried below the ocean floor, which are not at all visible.

The mag is normally towed behind a boat, (but can be used in other ways) one or more sensor-head is connected by umbilical cable to send magnetic data to the surface unit. A diver using scuba-equipment along with a hand held unit could also move a smaller variation of this instrument along the bottom. Magnetometers measure and record the bottom’s magnetic field, including and deviations caused by localized ferrous metal deposits.

As such, they detect only ferrous metals such as iron or steel, (as opposed to the nonferrous metals, which include gold and silver and bronze). But this usually enough to find a buried ship. Picking up the anchor or the cannons as a target.

Depending on its size (related to cost), mags may have the ability to detect a one-ton mass of ferrous-based material, such as cannon or anchors, at a maximum distance of up to 150 yards from the magnetometers sensor head.
