Listening to music while soaking in the hot tub is a relaxing way to enjoy an evening, but getting out of the warm water to change the radio station or select another song on the CD isn't exactly convenient. Unlike standard remote controls, which won't last long when they come into contact with water, the Dolphin Remote is a water resistant universal remote control that can control your spa's functions as well as all of your home theater devices, even if they're located behind closed doors up to 100 feet away.
