Do watch Hidden Fence 1200 FMD
Excellent customer service prior to purchase. Great delivery timeframe. Easy install. Large property boundary (total boundary of 750m) - system very consistent signal and does not cause an interference to the electric fence in place for livestock. Did not need to bury except at gates as able to use livestock fence already in place. Two dogs - very quick to learn. Flags very effective in training process. Highly recommend.
