Chart Recommendations for Zeus2?

[OrangeCrush]

Hello,

I've installed a 9" Zeus2 MFD and I'm a bit unfamiliar with the chart options these days. It came with a card loaded with C-Map MAX-N Continental USA. I'm going to be sailing Nova Scotia and the Bay of Fundy this summer so I need to supplement.

Can anyone briefly break down what type of chart cards are compatible with the Zeus2, or perhaps recommend a favorite brand and/or a good place to buy them?

Does anyone recommend "enhanced" or "platinum" charts for areas like Maine where we will be spending the most time?

Sorry for the basic question; I know there is a ton of info out there but I'm finding it a bit hard to discern the basics.

Thanks!
