Pig Tracker Receiver and Wand

To locate a pig equipped with a SPY® Transmitter, the SPY® PTR (Pig Tracker Receiver and Wand) registers the changing magnetic field produced by the SPY® Transmitter. When the Transmitter is located, the PTR produces both an audio and visual output. With two standard 9-volt alkaline batteries, the PTR can be powered continuously for approximately 50 hours. Special wands are available for sub-sea applications, with depths of up to 10,000 feet [3000 meters].
