The stylish metal detector will detect all kinds of metal from iron, coins and household items to precious metals like silver and gold. Streamlined in appearance, with only two operating controls and a mode selection switch, the Tracker IV has eliminated the most difficult aspect of metal detector operation: ground balancing. With built-in Automatic Ground Trac, the Tracker IV balances for mineralisation whilst you detect. The Tracker IV will detect in extreme ground conditions from salt wet beaches to highly mineralised inland sites with no operator adjustments to the circuitry or loss of sensitivity.
