A friend of mine just showed me the new sonar phone by vexilar with navionics. He is thinking about getting it for the front of his boat instead of replacing his hummingbird. Curious if anyone has used this and if so what was your set up? He is wanting to use it with an I pad, but make the mount weather proof. If you haven't seen it there is a video on YouTube vexilar sonar phone and navionics app. Curious for input...
