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.

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.
