Downloaded and used on a recent trip to the FL Keys – Marine Navigation - Lake Depth Maps - USA - Offline Gps Nautical Charts for Fishing, Sailing and Boating Review

Very useful in guiding through the keys channels. Once you have a map and want to plot a route this is very useful. Takes a little getting used to but got the job done. Harder to use on iPhone due to screen size.
