Can I use my Musky Hunter App in areas where I don't have cell coverage?

Absolutely! The Musky Hunter Mobile application has its own internal database.  When it finds connectivity to the internet it will automatically stay in sync with the weather, moon, and lake profile databases.  If you were to move out of cell range the data updates will stop, but the app will continue to function. Keep in mind that the longer you are in disconnected mode, the less accurate your information will be.
