NAVY
BUYS MAGNETOMETERS
The
Australian Navy is the latest military unit to purchase JW
Fishers Proton 4 magnetometers.
The Aussies join a long list of military clients using
Fishers underwater search equipment including the US Navy, the
Italian Navy, the Egyptian Navy, Argentina’s Perfectura
Naval, and Israeli military units.
The
Proton 4 magnetometer is a super sensitive metal detector that
will find ferrous metal objects laying on, or buried under,
the seafloor.
This rugged, reliable, easy to use instrument
can detect large shipwrecks more than a quarter of mile
away.
Even targets like ship’s anchors can be detected at a
range of 100 feet or more.
The military use magnetometers for a variety of search
operations including locating sunken vessels, detecting bombs
and other underwater explosive devices, finding lost anchors,
and identifying the location of pipelines and cables before
performing dredging operations.
The
Australian’s bought several of the Proton 4 mags equipped
with cables of varying lengths, underwater altimeters,
tracking software, and deep dive wings.
The altimeters are an important accessory that inform
the operator of the distance between the towfish and the ocean
floor.
This helps the user tow the mag close enough to the
bottom for maximum detection penetration, yet far enough away
from the seabed to avoid collision with underwater obstacles.
The tracking software allows the magnetometer readout
data, along with GPS position coordinates to be displayed and
stored on a PC.
Also shown on the computer is the track of the boat as
it passes back and forth across the search area.
The deep dive wing is an essential piece of equipment
for maximizing depth while minimizing the amount of cable
deployed.
With most towed equipment the typical ratio of cable
length to tow depth is 4 to 1 which means
400 feet of cable is required to tow at a depth of 100
feet.
The deep dive wing cuts the ratio in half to 2 to 1
which means that only 200 feet of cable is required to tow at
a depth of 100 feet.
In
addition to the Proton 4 boat-towed mag, Fishers also
manufacture a hand-held magnetometer the Diver Mag 1.
The Diver Mag has an the same detection range as the
Proton 4 and many of the features.
