The PROTON 5 is a fifth-generation protonmagnetometer from JW Fishers. It is a top performing microprocessor drivenmarine magnetometer detection system. The Proton 5 definitive detector for ironand steel targets. It's maximum range capability of 1,500 feet (450m) on eachside (3,000-foot total swath) lets you search a wide area quickly andcompletely. The mag is also a good choice to locate a variety of smallertargets such as pipelines, anchors, chains, cannons, dredge heads, etc. It isespecially useful when objects are buried in the bottom and can't be found withsonar or video search systems. The detection range is unaffected by the mediumbetween the magnetometer and the metal target. Performance does not changewhether detecting through air, water, silt, sand, or solid coral. It'sextremely large detection area make this magnetometer the ideal choice for bothcommercial operations and professional wreck hunters.

 

With a one Nano -Tesla (nT) sensitivity, ithas the maximum usable sensitivity for a towed proton precession magnetometer.A two second cycle time gives a strong return signal and is fast enough todetect even small iron/steel targets. The PROTON 5 features a triaxialnoise-cancelling sensor that allows omnidirectional towing without headingerror or dead zone. The system is fully digitized and displays the current5-digit measurement on an easy to read 6-inch LCD screen that is backlit fornight operations. Up to 80 of the previous measurements are also displayedgraphically in a history plot on the LCD. With the optional altimeter, distanceoff bottom of the towfish is displayed. User friendly menus allow easyconfiguration of all operation settings and system tuning directly from thetop-side control box. An adjustable audio alarm lets the operator decide howmuch of a change in the baseline reading will cause the alarm to fire.

 

The towfish has excellent hydrodynamiccharacteristics, moving smoothly through the water at tow speeds up to 10knots. The Fish can be towed at almost any speed, but should be towed slow tolocate small targets or when towing the Fish deep. A 2-3 knot tow speed isrecommended for small targets. With the optional UA-3 Altimeter, precisedistance off the bottom can be maintained. For deep water towing, the Fish istowed behind the optional DDW-1 Deep Dive Wing depressor. The collapsiblePROTON 5 towfish it easily fits into a watertight Pelican® case. Modularconstruction allows easy field repair, should it ever be necessary.

 

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