The following terms are used throughout the manual, and are standard terminology among treasure hunters. ELIMINATION Referencetoametalbeing"eliminated"meansthatthedetectorwillnot emitatone,norlightupanindicator,whenaspecifiedobjectpasses through the search coil’s detection field. DISCRIMINATION Whenthedetectoremitsdifferenttonesfordifferenttypesofmetals,and whenthedetector"eliminates"certainmetals,werefertothisasthe detector "discriminating" among different types of metals.

PINPOINTING Pinpointingistheprocessoffindingtheexactlocationofaburiedobject. Long-buried metals can appear to the eye exactly like the surrounding soil,andcanthereforebeveryhardtoisolatefromthesoil. V.C.O. Meaning “voltage controlled oscillator”, the V.C.O.audio method causes both the audio pitch and the volume to rise as signal strength increases. V.C.O. improves the user’s ability to interpret a target’s size and depth. Very weak signals (for small or very deeply buried objects) have the faintest volume and the lowest pitch. Larger objects, and those closer to the search coil, will induce a higher volume and higher pitch sound. GROUND BALANCE Ground Balancing is the ability of the detector to ignore, or "see through" the earth’snaturallyoccurringminerals,andonlysoundatonewhenametal object is detected. The DISCOVER deluxe incorporates proprietary circuitry and programming to eliminate false signals from severe ground conditions.
