ET-402 2T 雙犬 Educator 附2個發射器

The backup transmitter is a lifesaver—I keep one in the barn and one by the back door, so I’m never scrambling when I need to correct a dog. Switching between the two collars on the same frequency is quick, and the range covers our full grazing field without a single drop.

We run a big fenced property so having one transmitter in the barn and one in the house is exactly why I grabbed this set. The frequency matching between the two units worked right out of the box, no fiddly pairing needed. Both dogs respond on the same level, which saves me a lot of guesswork.
