Great buy

Great app. Using it right now on my travel down the Chesapeake. Has speed, depth and I can download tons of noaa charts without additional charge that are accessible offline. Also one thing I like is to place a waypoint when I anchor. In the night if I am worried I am drifting I check this app to see where my gps is versus the anchor. That is super useful in my book.
