The new PT-101 transmitter measures 25.4 mm in diameter and 106.4 mm in length.

Like all SPY Pig Tracking Systems, the new transmitter is used in conjunction with a receiver unit and a wand (SPY PTR) to pinpoint the pig’s location. The SPY Model PT 101 has a free air space pick-up range of 15 to 20 feet with an underground depth range of 4 to 6 feet. The new model can be used in temperatures ranging from –28˚C to 82˚C. A 3 volt lithium battery powers this new transmitter for up to 60 hours.
