Marine Navigator Customer Insights

1. The reason I gave 4 stars instead Of 5 is the Ais add on which i have paid forkeeps asking me if I want to buy it again.Great App at a Great Pricel Iv'e been using MN for three years now using VMH UKHO charts and it's performed faultlessly around GB from Isles of Scilly to Orkneys.

2. Purchase permits installation on multiple devices as backup.didnt get a chance to actually see what it will do, bought and downloaded the uk/irl chartset, but the app consistently refused to see it, (android6) , so uninstalling the app.I have used it on a tablet as a backup system using charts from visit my harbour.

3. I got the charts via visit my harbour and they are extremely affordable compared to some of the other offerings available.I would highly recommend this app to anyone wanting a easy to use fully functioning chart plotter.

4. Both Ronald Koenig the developer and Steve Bryant at VMH who supply the charts are to be heartily congratulated on making this package available.Works well for me on klunky old kitkat tablet.

5. One caveat, and the reason I couldn't give 5 Stars: as a raster chart lover (vs vector charts like Navionics), there's a danger: no corrections are applied.

6. Can be a primary chart plotter allowing you to see your boat's position superimposed on the latest NOAA charts.

7. Thank you again Mr Koenig for a great product.This is a wonderfull app but I cant figure out how to import Army Corps/Western Rivers charts.

8. Please help and I gladly give you back that last star.I installed this app on my Google Nexus 7 tablet, with uk charts from visitmyharbour.

9. I love the app and I just wish I could use it on the Western Rivers with Army Corps charts.

10. We are now on a new boat, full of all sorts of fancy built-in electronics, and I will not head offshore without my Android tablets loaded with Marine Navigator.

11. Ive been using this app for over 6 years for vessels 10ft to over 100ft at times, and in waters from Maine to Texas.
