JW Fisher Diver Mag-1 Hand Held Magnetometer
The Diver Mag 1 is a top performing microprocessor driven marine magnetometer detection system with a one nano-tesla sensitivity. This and-held mag is a super sensitive detector of ferrous metal (iron/steel) that works equally well on land and underwater. The mag will locate pipelines, cables, cannons, dredge parts, and just about any ferrous metal object of any size. Ruggedly constructed for commercial operations, the Diver Mag 1 was designed with user-friendly controls for easy operation. The handle grip makes the mag easy to carry out of the water. The system includes a Pelican hard carry case to transport the system quickly.
Operator-selectable cycle times (how often reading is taken)of 2, 5, or 10 seconds allow for a strong return signal and a fast response to detect even small targets. An adjustable sensitivity switch makes pin pointing even the largest of targets extremely easy. The Diver Mag 1 features a triaxial noise-canceling sensor that lets the mag be held in any position without affecting the sensitivity or stability of the readout. The readout is displayed on an easy-to-see 5-digit LED for murky water or night operations. In addition, an audio output allows the diver to operate the system without the need to watch the LED display. Easy to maneuver with operator-adjustable buoyancy, the Diver Mag 1 can be used anywhere in the world.
Power is supplied by an internal 12-volt rechargeable battery that lasts for two continuous hours at the 5-second cycle time. The optional belt-mounted spare battery pack increases the operating time. The included battery charger connects to any 120-volt AC voltage source (a 220-volt charger is optional).
General Information
Magnetometers are precision electronic instruments that mea-sure and display the strength of the earth’s magnetic field in an area. If ferrous metal is present, the earth’s magnetic field is altered and the readout of the magnetometer changes accordingly. Since the 1940’s, almost every major wreck find was made with a magnetometer. Metal hulled ships and barges are easy tar-gets and can be detected hundreds of feet away. The Spanish galleons laden with gold and silver (metal not detectable by magnetometer) were also found with mags by detecting the ship’s anchors, cannons, cannon balls, or ballast stones (magnetite was often used as ballast).
In the 1960’s, the proton magnetometer (as we know it today) was invented. Since that time the proton magnetometer has dominated the field, both in the scientific community and incsalvage work. It is both a rugged and sensitive instrument. The claim to fame of the proton magnetometer is, unlike flux-gate mags, the orientation of the sensor head does not alter the out-put reading. Once this mag is tuned to an area, no further adjustments are necessary.
