With a 200-foot depth rated housing and a 6-foot maximum detection range, the Pulse 8X is Fisher’s top-of-the-line detector. Its 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 its ability to ignore minerals in the environment while maintaining high sensitivity to all metal targets. It is not affected by highly mineralized saltwater, coral, rocks with 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 saltwater. The diver is alerted to the 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. Performance does not vary whether detecting through the air, water, silt, sand, or solid coral.

The JW Fisher 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, a 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 is 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.

JW Fishers Pulse 8x has been rated the best underwater metal detector by the US Department of Homeland Security’s SAVER program.
