Crystal controlled frequency in both transmitter and receiver increases tracing distance

Conduct "blind" searches of an area to locate an underground pipe or cable when the starting point is unknown

Voltage Controlled Oscillator gives a wider range of audio signals to indicate the presence of metal (even after the meter pegs, the audio signal goes much higher in pitch and volume)

Noise cancelling circuitry elininates power line interference

Powered by 16 standard penlight (AA) batteries (eight in each of the transmitter and receiver)
