JW Fishers Proton 4 Underwater Magnetometer

The Latest Generation JW Fishers Magnetometer The PROTON 4 is a fourth generation proton magnetometer from JW Fishers. It is a top performing microprocessor driven marine magnetometer detection system. With a one gamma sensitivity, it has the maximum usable sensitivity for a towed magnetometer. A two second cycle time gives a strong return signal and is fast enough to detect even small iron/steel targets. The PROTON 4 features a triaxial noise-cancelling sensor that allows omnidirectional towing without heading error or dead zone. Easy To Read Backlit Display The system is fully digitized and displays it’s output on an easy to read 5 digit LCD that is backlit for night operations. The optional built-in printer creates a permanent record of the mag readouts. The gamma reading is printed out on each cycle and, with input from a GPS receiver, the target’s position is also printed out. An alarm informs the operator when the readout changes. An RS232 output and software package are als
