The RX101 Receiver is a high tech unit that is used to detect the distinctive pulsing patterns of passing pigs. Both analog and digital displays allow signal strengths to be viewed in all light conditions. The adjustable gain with bright bar display and coded signals A, B, C help indicate the precise location of the transmitter. The new unit also comes with a built-in geophone to detect approaching and departing pigs. A durable, shock resistant pelican case provides storage for all of the RX101 Receiver equipment. The accessories in the pig detector case include an external wand antenna, 50’ antenna extension cable, 2-6’ antenna cable, 50’cable with a spike probe, 6’audio cable for vehicle hook up, and a pair of highly efficient noise reducing headphones.
