Re: Navionics web charts and SonarCharts
I purchased the Navionics app for the iPhone. Haven't tried the sonar feature yet but I know they are trying to get me to upgrade for more money. Its worth the $10 I spent, but its not very reliable. It eats your battery very fast. If your sailing in an area like I am with sketchy service it doesn't work. Mine has tracked my boat across land. I still think its a good back up. It could be the way of the future, as cell service and devices get better.
