I'm out of the dog biz now. I have a 8 dog Magnum Telemetry tracking system. 8 collar's in 224 freq,deluxe tracking box, case, 12 volt and 110 volt charger. The tracking box has an atunuator and will track any frequency. $800.00
Also have 6 Tri-Tronic Shock collar's, 2 transmitter's and charger's. $600.00
Both system's have proven to be very reliable and have been taken care of. PM me if you are interested. Frank
