Metal Detector vs. Magnetometer
If you are searching primarily for nonferrous metal (gold, silver, lead, brass, bronze, aluminum, etc.), the best piece of equipment is a metal detector (Pulse 6X, Pulse 8X or SAR-1).
If you are searching primarily for ferrous metal objects (iron and steel), the best piece of equipment is a magnetometer (DiverMag-1 or PT-1). The advantage of using a magnetometer is that it has a much greater detection area than a metal detector.
SAR-1
Snareless metal detector, no external wires or cables.
JW Fishers SAR-1 was specifically designed for military, law enforcement and public safety dive teams to locate metallic objects in low visibility environments. The "snareless" SAR-1 has a streamlined design with no external wires or cables which makes this detector the ideal tool for work in environments with potential entanglement hazards.

The highest performance diver-held ferrous metal detector on the market today.
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 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 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).

Fishers' top of the line detector.
With a 200 foot depth rated housing and a 6 foot maximum detection range, the Pulse 8X is Fishers top of the line detector. It's heavy duty construction and high sensitivity make the Pulse 8X the choice of professionals everywhere. This commercial-grade metal detector is used by treasure hunters, commercial diving companies, law enforcement agencies, and military units worldwide.
The claim-to-fame of this pulse induction detector is it's ability to ignore minerals in the environment while maintaining high sensitivity to all metal targets. It is not affected by highly mineralized salt water, coral, rocks with a high iron content, or magnetic (black) sand; all of which drive conventional metal detectors crazy. The Pulse 8X detects all metals from coins and jewelry, to anchors and cannons; and does it on land, or in fresh or salt water. The diver is alerted to presence of a metal target by both visual readout (shown on the meter) and an audio output (heard in the underwater earphone). The detection range for a target is unaffected by the medium between the detector's coil and the metal object. Diver with Pulse 8X and Spanish coins Performance does not vary whether detecting through air, water, silt, sand, or solid coral.
The Pulse 8X comes with all the accessories needed to use the detector on land or dive to depths of over 200 feet. The standard package includes a corrosion proof PVC handle for underwater use, an anodized aluminum handle for land use, underwater and land headphones. The package also includes AC and DC battery chargers, a hip-mount kit for the electronics housing, rugged Cordura carry bag, spare parts kit, and JW Fishers Search Team hat.
Powered by an internal 9 volt rechargeable battery pack, the detector will easily run all day on a full charge. Recharge the battery overnight, and it's ready for another full day of hunting.
A complete line of interchangeable coils are available which gives this detector tremendous versatility. Two of the coils can be deployed from a boat; the operator can be topside with the electronics unit, and have a coil on the bottom searching for metal. See below for additional options.
The Pulse 8X has double the power and detection range of the Pulse 6X detector.
