  • Crystal controlled frequency in both transmitter and receiver increases tracing distance
  • Unlike other units that use a separate transmitter and receiver, the TW-6 when mounted on the handle, can conduct "blind" searches of an area to locate an underground pipe or cable when the starting point is unknown
  • VCO (Voltage Controlled Oscillator) gives a wider range of audio single to indicate the presence of metal. Even after the meter pegs, the audio signal goes much higher in pitch and volume
  • Noise canceling circuitry eliminates power line interference
  • The TW-6 is powered by 16 standard AA (penlight) batteries: eight in the transmitter and eight in the receiver
  • The TW-6 weighs only 5 1/2 lbs.
