The waterproof SoniTrack XLR geophone based pipeline pig tracking system can be used to track any pig by simply plugging the geophone into the soil and either listening for pigs via the supplied headphones, or by using the built-in FM transmitter to wirelessly transmit the audio to your vehicle.

 

Simply press the AutoTune search button and SoniTrack XLR will automatically find the quietest unused FM band and begin transmitting audio. Tune your vehicles to the same FM frequency and any number of people can hear the pig’s approach. No headphones required.
