Fisher Research Labs Research Metal Detector, Analogue (M-101)

Research Metal DetectorDesigned specifically for finding reinforcing bars and other metal objects embedded in concrete, conduits, PK nails, wiring, wall studs, and other metallic objectsA preset circuit eliminates ground effects caused by highly mineralized materials and false signals due to loop movementCan effectively locate small metal items carried on or within a person and is substantially more sensitive than the average low cost metal detectors used at airports, so that a given metal item can be found at a greater distance from the search loop itselfSearch loop and cord are waterproof, so searches in water may be up to the control boxDetects all metalsDetects intersections of rebar or meshSignals audio and visual indications of nearby metalRugged constructionQuick-tune, ready for operation in seconds as only the penetration control needs to be adjusted for most operations, allowing maximum penetration depth for metalsAccurately pinpoints steel reinforcing bars, or "rebars" in concreteVLF (Very Low Frequency) operationOperates on two universally available 9V batteries
