By: Dave From GAI purchased this unit and two collars for my Great Danes. Training was extremely easy, as my dogs already knew the commands and only needed to learn to associate the ringer & vibrator to the desired action. They now respond to stimulus at long distances without my needing to yell. I dropped the handheld into water, and it survived a ten minute submersion without issue.
