JW Fishers Metal Detectors

Key Features of the Diver Mag 1:
Commercial grade construction, LED and audio readout, audio jack with detachable headphones, rechargeable batteries, and optional "extended operation" belt mounted extra battery pack.

The Diver Mag 1 is backed by Fishers exclusive, unconditional TWO YEAR warranty.

The 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 and underwater. The mag will locate pipe lines, 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 and included shoulder strap make 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 even the largest of targets extremely easy. The Diver Mag 1 features a triaxial noise-canceling sensor that let the mag be held in any position without affecting sensitivity or stability of the readout. The readout is displayed on an easy to see 5 digit LED for murky water or night operations. In addition, an audio output allows the diver to operate the system without the need to watch the LED display. Easy to maneuver with operator adjustable buoyancy, the Diver Mag 1 can be used 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 spare battery pack. The included battery charger connects to any 120 ac voltage source (220 ac charger is optional).Diver swimming with DiverMag

The Diver Mag 1 is constructed of corrosion proof urethane and PVC to give many years of trouble free performance. Modular construction allows for easy field repair, should it ever be necessary.

Key Features of the Proton 4:
Commercial grade construction, extremely large detection range, faster towing speeds than Pulse systems, and ability to make a permanent record of mag readouts with position coordinates.

The Proton 4 is backed by Fishers exclusive, unconditional TWO YEAR warranty.

This high performance marine magnetometer is ruggedly built and easy to operate. The topside console has both audio and visual alarms for target detection. Connect a GPS and position coordinates can be captured with the mag readout data on a built-in printer. The control box has an adjustable sensitivity switch that lets the operator select maximum sensitivity for open water searches or a lower sensitivity setting to work in rivers or harbors where steel structures may be nearby. A cycle time switch lets the operator choose a 2, 3, or 4 second cycle time. Selecting a longer time is helpful when working in an area with a weak magnetic field. An adjustable audio alarm lets the operator decide how much of a change in the baseline reading will cause the alarm to fire. When searching for small targets, low alarm settings alert the operator to small changes in the readout. Higher alarm settings cause the alarm to fire only when a significant ferrous metal object is detected.

Key Features of the Pulse 12:
Commercial Grade Construction, ability
to tow up to three coils for extra large detection area, optional computer
interface, faster towing speeds than the Pulse 10 system, and audio jack for headphones.

The Pulse 12 is backed by JW Fishers exclusive, unconditional TWO YEAR warranty.

With it's 24 foot wide and 16 foot deep detection envelope this detector will locate a variety of targets including aluminum boats, brass propellers, outboard motors, steel anchors, bronze cannons, and gold bars.  One of the key features of this detector is the control unit which can accept inputs from 3 search coils.  Using three coils instead of one lets the search team cover three times the area with the same amount of time, fuel, and manpower. 

The claim-to-fame of this pulse induction metal detector is its ability to ignore minerals in the environment while maintaining high sensitivity to all metal targets. The Pulse 12 is not affected by highly mineralized salt water, coral, high iron content rocks, or magnetic (black) sand, all of which cause erratic readings in conventional detectors. Also, the detection range is unaffected by the medium between the metal detector and the metal target. Performance does not change whether detecting through air, water, silt, sand, or solid coral.

The Pulse 12 system includes a 24 by 36 inch search coil with 150 feet of cable, tow fish, and a top-side control unit. The control unit features three sets of operator controls which allow up to three coils to be towed simultaneously. Both meter and audio readouts indicate target detection from each individual coil. Options include cable lengths up to 500 feet, UA-2 altimeter, RS232 output interface, 0 - 5 volt analog output, and DDW-1 deep dive wing.  The RS232 allows the Pulse 12 readout data along with GPS position coordinates to be displayed and stored on a computer. The system is powered by two 12 volt batteries with a total power consumption of only 12 watts.

The Pulse 12 is in use by military, law enforcement, commercial, and salvage divers world wide. High sensitivity and a very large detection area make this detector an excellent choice for both commercial operations and professional treasure hunters.

SeaOtter-2 is backed by Fishers exclusive, unconditional TWO YEAR warranty.

System controls for the SeaOtter-2 are cleanly laid out in a high impact water proof case with an ultra bright 10.4 inch flat screen monitor built into the lid. Command of the ROV's thrusters, cameras, and lights are managed with a PS-2 controller. A wireless controller can also be used to give the operator even greater freedom. A gentle push on the vertical joystick propels the vehicle down into the depths, and a nudge on the horizontal sends the ROV flying over the ocean floor. The control panel has jacks and amplifiers which make it adaptable to the requirements of each job. A video output jack allows an additional remote monitor to be used simultaneously with the internal flat screen monitor. Other viewers can see the world below without crowding around the control console. An internal video amplifier adjusts picture quality to optimize the video for water clarity. Connect a VCR or DVD recorder and make a permanent record of the underwater scene. With the internal audio amplifier voice can also recorded with the video picture.

Fishers offer three different side scan systems the SSS-100K, the SSS-600K, and the SSS-100K/600K dual frequency side scan.

The 600K single frequency side scan is ideal for law enforcement and dive rescue operations. It produces very high resolution images at ranges up to 200'(400' swath). This high frequency sonar can show small, soft targets like a drowning victim, clothing, etc, that lower frequency (100K to 300K) sonars have difficulty detecting. The 600K side scan is also popular with wreck hunters and archaeologists searching for old wood vessels that may be broken up or decomposing. The limitation of the 600K is it's shorter range as compared to the 100K side scan.

The SSS-100K single frequency side scan is best for wreck hunting or general search applications such as locating pipelines, logs, rocks and reef structures, large propellers, and sunken vessels. It has excellent long range capabilities (up to 1,800' per side/3,600' swath) for locating large wrecks. When operating in the shorter ranges it clearly shows objects less than 1 foot in diameter.

The SSS-100K/600K side scan has both low and high frequency transducers in one towfish. It offers the best features of both systems. The operator can switch between 100K and 600K at any time during operation. Typically a search begins using the 100K on one of the longer range settings. When a target is spotted, the operator switches to the 600K and makes a closer pass to get the highest resolution image. NOTE: Some side scan manufacturers have separate towfish for each frequency. To switch frequencies, one towfish must be reeled into the boat and another deployed; an inconvenient and time consuming operation. With Fishers dual frequency side scan, both high and low frequency transducers are mounted in one towfish.

Each side scan system is backed by Fishers exclusive, unconditional TWO YEAR warranty.
