  • Surface to underwater viewing device attachment for metal detector
    Publication number: 20040150403
    Abstract: A Surface to Underwater Viewing Device Attachment for a Metal Detector. A tube, with clear sheet glass cut to shape and inserted and sealed in one end to make it waterproof, the other end being left open. The tube is long enough to keep the opened end out of the water. The tube is mounted a small distance from, and attached to, the body of the metal detector. The tube is positioned parallel, or almost parallel, at angles that allow the operator to see through the tube, while holding the metal detector. The operator may now see clearly below the surface of the water and see where the search coil on the metal detector has passed over.

  • Magnetic detector extendable wand
    Publication number: 20040145369
    Abstract: A wand-type magnetic metal detector has a telescoping wand which shortens the wand sufficiently for the detector to be comfortably carried in a holster carried on the user's body. The user's hands are thereby freed for other tasks than carrying the detector.
