Zusammenfassung:	A line tracer is disclosed comprising a transmitter for generating a signal in a target pipe, a cable set, a detector for amplifying the signal and filtering unwanted electronic noise, and a method for employing the line tracer. The transmitter further comprises a transmitter circuit board having a pulse generation circuit, a tone generation circuit and a transformer drive circuit. The transmitter circuit board is tuned to provide a pulse frequency of approximately 1.3 Hz and a tone rate of approximately 600 Hz. The detector further comprises a detector circuit board having a difference amplifier, a first high pass filter, a second high pass filter, a non-inverting amplifier, and a sensitivity meter. The detector circuit board is designed to amplify the detected signal and to achieve an attenuation of frequencies from 0 Hz to 400 Hz that is 80 dB/decade. The detector provides a visual indicator of signal strength.
