I exchanged this product which did not correspond to my device. A consultant immediately saw the problem and offered me the adapted product. I received it 24 hours later, while I was in Kiel and I am French.
I use the C-Map MAX Baltic Sea and Denmark for many years (of course, with half price updates) in my very reasonably priced standard Horizon 180i chart plotter. Despite the large area I can zoom in very far and then have a surprisingly good resolution. In the harbors the individual bollards are often pictured. Even the Göta Canal and the Swedish inland lakes are included. Navigation in the archipelago is really easy and straightforward with this map. So far, I have noticed no errors! I can really recommend this card!
My standard Horizon GP 300 chart plotter no longer booted with the new card. SVB helped quickly and sent me a software update. Great service, straightforward. (the rating applies more to SVB than the card set itself ...)
