C-MAP

C-MAP provides world-class marine cartography and digital mapping services, offering boaters the most detailed and accurate data for lakes, coasts, and oceans. Known for innovative features like High-Resolution Bathymetry, Custom Depth Shading, and the game-changing "Reveal" layer—which provides shaded relief for seafloor structures—C-MAP helps anglers find the best spots and navigators find the safest routes. Their charts are compatible with the world’s leading electronics, including Simrad, Lowrance, and B&G. At Freeport Marine Supply, we carry C-MAP Discover and Reveal charts to give you the ultimate situational awareness and fishing advantage.
