The JW Fisher DIVER MAG 1 is a top-performing microprocessor-driven marine magnetometer detection system with a one gamma sensitivity. This hand held mag is a super-sensitive detector of ferrous metal (iron/steel) that works equally well on land or underwater. The mag will locate pipelines, cables, cannons, dredge parts, and just about any ferrous metal object of any size. Ruggedly constructed for commercial operations, the DIVER MAG 1 was designed with user-friendly controls for ease of operation. Out of the water, the handle grip makes the mag easy to carry.
Operator selectable cycle times (how often a reading is taken) of 2, 5, or 10 seconds allow for a strong return signal and a fast response to detect even small targets. An adjustable sensitivity switch makes pinpointing targets extremely easy. The DIVER MAG 1 features a tri-axial noise-cancelling sensor that allows the mag to be held in any position without affecting the readout’s sensitivity or stability. The readout is displayed on an easy-to-see 5 digit LED for murky water or night operations. Also, an audio output allows the diver to operate the system without watching the LED display. Easy to maneuver with operator adjustable buoyancy, the operator can use the DIVER MAG 1 anywhere in the world.
Power is supplied by an internal 12-volt rechargeable battery that will last for two continuous hours at the 5 second cycle time. Increase the operating time by using the optional belt-mounted external battery pack.
The DIVER MAG 1 is constructed of corrosion-proof urethane and PVC to give many years of trouble-free performance. The modular construction allows for easy field repair, should it ever be necessary.
