Navionics platinum card
 

Need some info on the platinum navionics cards. If any of you have the western gulf of mexico, How far east does the coverage run? Will I have to get a western and central to get all the way to Dularge/grand isle area?

Get the 907P Platinum card. Covers everything you need in one card.

I run it in a Simrad NSS12 and the aerial overlays are really helpful exploring the marsh.
