Abstract: A high-Q human-portable, battery-powered self-correcting tunable resonator in a transmitter apparatus for inducing alternating currents of high quality in buried conductors to facilitate their location is disclosed. The transmitter apparatus may employ an FET-driven capacitive tuning circuit and a coil design that achieves high precision, high-quality transmission signals, and which may be equipped with a high-voltage booster for facilitating fault-localization applications.
