The Digital Ground Pioneer 4500 is totally new high technology pulse induction detector - combination of Metal detector and Magnetometer Sensor System, one of the best professional pulse induction metal detectors in existence. RS 232 port is propvided for connection to computer and GPS system for localizing. Ground Pioneer 4500 is designed for detecting deeply buried or lost metal objects, metal pipes, underground communication equipment, treasures and similar objects. The unit works by the principle of electromagnetic induction at very low frequency, which allows penetration deeply in the ground. The depth,combined with iron object discrimination, automatic tuning and the choice of different regimes for searching, make the unit hardly replaceable in a lot of situations. The GP4500 can easily detect larger objects buried up to 8m deep.
