Dog Training Collar 800M Remote Transmitter for M880-1/M880-2/M880-3

Highly recommend. Installation took approx. 3 hours with two people. Rented a wire and cable burying trencher from local hardware store. Trencher did not bury the wire well, so we did some manually work on hands/knees to bury into ground. Wired through a crack in our drive way to completely surround property. We surrounded our 1/2 acre lot, but ran out of wire near the end and needed to buy additional wheel of wire. Took some trial and error with collar settings to find the right amount for our 30 lb dog. After 2-3 weeks of training, our dog knows his boundaries. Still continue to have him wear the collar though.
