ET-300 2T ミニ教育者（送信機2台付き）

Two transmitters on the same frequency is exactly what we needed for our place—one stays in the barn and the other in the house, so I never have to go searching when the dogs are out back. Setup took about ten minutes and I’ve had zero signal drops across the yard so far.

The two transmitters on the same frequency are handy for keeping one in the barn and one in the house, but I wish the range between them was a bit more forgiving through walls. Works fine for what it is, just don’t expect it to reach across a big property without line of sight.
