1. Be sure to know at least a little about marine rules before hand.Worked great when boat gps back light died at night.
2. pulled my tablet out of the boat today to get it ready for the spring the app will not work without an update and you have to purchase the update.
3. Very irritating.It's a great app, the maps are very detailed.
4. they disabled most of the features on the old version so it's basically useless total BS.
5. i talked to a friend of mine he had the same problemIt seems to freeze a lot while in use.
6. DO NOT BUY!!!!!!! i purchased this app about a year ago for $20.
7. I had to buy the app for a second time because it said I did not have the pro.
8. Got us back to MDR in the fog.Awesome App! Works great! Very convenient and accurate!What a great app to have currents charts at your fingertips.Don't know what to think about this app.
