Collection: C-Map Discover x / Reveal X

C-MAP REVEAL X chart cards deliver high-definition bathymetric detail aimed at anglers and navigators who want to see underwater terrain, not just flat depth readings. The shaded relief and dense contour data help you identify structure, drop-offs, and productive fishing zones that standard charts miss. Coverage varies widely across the 19 cards here, so the first decision is geography. The U.S. Lakes series divides the country into regional sets covering West, North Central, North East, South Central, and South East, while separate cards handle Canada Lake Insight West HD and East HD. Coastal and offshore options include Alaska, Canada North and East, Hawaii with the Marshall Islands and French Polynesia, and South American waters from the Gulf of Paria to Cape Horn.

Before purchasing, confirm that your chartplotter accepts C-MAP REVEAL X format, since chart card compatibility varies by manufacturer and device generation. Check whether you need a microSD or SD format for your unit's card slot. If you fish primarily inland lakes, the regional lake cards give you the densest freshwater detail. If you run coastal or bluewater passages, match the card to your actual cruising area rather than buying overlapping coverage you will never use.
