The Kustfijn model gives you the most accurate information about the North Sea and the Waddenzee.
To use this extra information, you need a paid license of WinGPS Marine of Marine Plus. After completing your order, you will receive an e-mail with a license code. Please make sure you have the most recent version of the app. When starting up, you may enter your code. This will allow you to access the extra source right away.
Please mind: we recommend the usage of the Kustfijn model in combination with our DKW 1800 charts.
