I find the digital hooey pretty awesome. And, it adds amazing redundancy. We have the Garmin installed, a hand held garmin, tablet and everyone's phones. Paper charts in the chart table also. All of the android devices have Navionics. I can be sleeping in my bunk and look at my phone to see where we are, etc. I have a Nexus Multi display as well to see anything else, but Navionics on the phone is pretty sweet. Having it in my sunglasses will be even more sweet.

All this digital hooey will just get you killed.
