There are a whole lot of other advantages, but to be honest, if you just use it for basic navigation, you prob will not get much out of it.
Down at Barkley lake, knowing where the creeks are for getting into some of those REALLY SKINNY bays is pretty dang critical. The Navionics upgrade I did last year added significant detail and I feel extremely comfortable going in bays I would have never went in before.
Obviously, you need to be crazy careful still, but as a tool it makes it easier to make some of those decisions.
Finally, Navionics Sonar Log upload allows you to upload sonar logs, so it helps the overall detail for everyone.
