How many of you have them? How many of you that do use them regularly? The wife is asking about having one installed. She likes to fish and generally likes to be on the boat but always says she'd like music. I'm not much of a fan of them especially while fishing but I talked to a couple people and they like them when running. We don't "sandbar" much so I'm not sure when else it would be used. Let me hear your pro's & con's.
