The Fisher TW-6 metal detector is the industry leading 2-box locator. The Fisher TW-6 is excellent for blind searches. Crystal controlled frequency in both transmitter and receiver increases tracing distance. Unlike other units that use a separate transmitter and receiver, the Fisher 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 Fisher TW-6 is powered by 16 standard AA (penlight) batteries: eight in the transmitter and eight in the receiver. NOTE: BATTERIES ARE NOT INCLUDED. REMOVED FROM SERVICE, GOOD CONDITION. INCLUDES STANDARD ACCESSORIES AND MANUAL. OPTIONAL ACCESSORIES AVAILABLE FROM THE MANUFACTURER. GUARANTEED FOR 30 DAYS. |
