I would love to come to this. I never have been able to understand sonar settings and I deal with computers all the time. But I cannot make this one. 2hr drive each way and the Easter Bunny has to visit that night at my house. Maybe next time our one of you will take pity on me and let me supply the boat and Humminbird and in return you can show me how to do more that turn it on, which is about as good as it gets now
