JW Fishers Proton 5 Boat Towed Magnetometer

Special Features:

With a one Nano-Tesla (nT) sensitivity, it has the maximum usable sensitivity for a towed proton precession magnetometer. A two-second cycle time gives a strong return signal and is fast enough to detect even small iron/steel targets. The PROTON 5 features a triaxial noise-canceling sensor that allows omnidirectional towing without heading error or dead zone. The system is fully digitized and displays the current 5-digit measurement on an easy-to-read6-inch LCD screen backlit for night operations. Up to 80 previous measurements are also shown graphically in a history plot on the LCD. The distance off the bottom of the tow fish is displayed with the optional altimeter. User-friendly menus allow easy configuration of all operation settings and system tuning directly from the top-side control box. An adjustable audio alarm lets the operator decide how much a change in the baseline reading will cause the alarm to fire.

The towfish has excellent hydrodynamic characteristics, moving smoothly through the water at tow speeds up to 10 knots. The Fish can be towed at almost any speed but should be towed slowly to locate small targets or when towing the Fish deep. A 2-3 knot tow speed is recommended for small targets. With the optional UA-3 Altimeter, precise distance off the bottom can be maintained. The Fish is towed behind the optional DDW-1 Deep Dive Wing depressor for deep-water towing. The collapsible PROTON 5 towfish it easily fits into a watertight Pelican® case. Modular construction allows easy field repair, should it ever be necessary.

The base system includes a 200-foot depth rated towfish, 150 feet of Kevlar reinforced tow cable, and topside control box. Optional USB data output and Tracker 3 software are available which allow the mag readout to be displayed on a laptop computer, along with GPS position coordinates. Target position is displayed and recorded on the computer. An optional Microsoft Surface ® tablet can be mounted in the control box lid, eliminating the need for a separate laptop computer making it a streamlined package.
