Using strong low frequency signals the Pig Tracker system gives you a more reliable signal life. Depending on the model, the Pig Trackers signal can be received for up to 500 hours. It operates on standard batteries - readily available from retail stores. No recharger is necessary.
The Pig Tracker system consists of a cylindrical transmitter which travels with the pig, and a hand-held pick up wand and receiver that receive the signals and inform the operator of the transmitter / pigs location.
