The stylish Tracker IV Metal Detector will detect all kinds of metal, from iron relics, coins and household items to precious metals like silver and gold. 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 track, the Tracker IV balances for mineralization while you detect. The Tracker IV will detect in extreme ground conditions from salt wet beaches to highly mineralized inland sites with no operator adjustments to the circuitry and with no loss of sensitivity. Meant for the outdoor enthusiast, the Tracker IV is fun and effective.
