JW Fishers Proton 4 Underwater Magnetometer

JW Fishers Proton 4 Underwater MagnetometerThe 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 DisplayThe system is fully digitized and displays its 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 also available
