Training collars for 2 dogs

[ Version-2 Receivers for 2 Dogs]
The remote has two channels. You can sync the two receivers to the two different channels (channel 1 and 2) and train your dogs separately. For example, when you choose channel 1 and press the vibration button, only the receiver synced to channel 1 will vibrate.
Or you can also sync both receivers to the same channel (1 for example) and control them at the same time. When you choose channel 1 and press the vibration button, both receivers will vibrate at the same time.
