ET-400 2T 1犬用トレーナー（送信機2台付き）

Left one transmitter in the barn and kept the other in the kitchen, so I don’t have to run back and forth when the dog wanders off. Both remotes work smoothly on the same frequency, and the range covers our whole property without any lag.

Having two remotes on the same frequency is a game-changer since I can keep one in the barn and one by the back door without ever having to run back for the other. The range is solid and I've had zero confusion about which remote works the collar.

The matching between my two transmitters has been flawless since day one, which is exactly what I needed for managing my dog across the far end of our pasture. I keep one clipped to my waist in the barn and the other by the back door, and the range holds up great no matter where the dog is.
