JW Fisher RMD-1 Remote Metal Detector
The RMD-1 is a high-performance pulse induction metal detector that can be attached to almost any ROV or towed underwater system, as shown in the photo. Pulse induction technology allows the RMD-1 to detect ferrous and non-ferrous metal objects on or beneath the ocean floor while ignoring minerals in the seabed. The remote metal detector locates and tracks underwater pipelines, finds missing tools and dredge parts, locates weapons and unexploded ordnance, and finds lost treasure.
The system employs two coils molded into rugged ABS shells firmly attached to the underwater vehicle with a corrosion-proof tubular PVC frame. The frame provides a sturdy mount for the coils and positions them out in front of the ROV so as not to be affected by the ROV's metal parts. The oval coils produce a detection envelope that extends 3 to 5 feet into the bottom. The sleek, low-profile coil design minimizes drag and weight on the ROV.
The standard RMD-1 has a control box which displays the readout with both meter and audio alarm. The closer the proximity of the metal target, the stronger the reading. The unit can use the underwater vehicle's umbilical cable to supply voltage to the downstairs electronics unit and to receive the output signal from the downstairs unit. The RMD-1 can be powered from 120 vac (standard) or 220 vac, or 9-36 vdc.
When the coil senses metal, it sends a signal to the RMD-1 "downstairs electronics unit" attached to the underwater vehicle. The downstairs electronics unit processes the information and can produce serial data output, 0-5 VDC output, or a proprietary signal used by the JWF control/readout unit. The output from the downstairs electronics unit can be transmitted through the ROV's umbilical or a separate cable. The ROV can power the downstairs electronics unit or supply power from the surface through the umbilical cable.
