C-MAP NA-M033 Max MegaWide microSD Atlantic Coast, Gulf o Mexico and Caribbean

The C-MAP NA-M033 Max MegaWide microSD Atlantic Coast, Gulf of Mexico and Caribbean chart card is an essential navigational tool for serious boaters and commercial operators working coastal and offshore waters. Whether you're running the intracoastal waterway, crossing the Gulf, or navigating through the islands, this microSD cartridge delivers the high-resolution chart data needed to fish and transit safely. Built by Navico's trusted C-MAP division, it's the standard choice for anglers, charter captains, and mariners who demand chart accuracy where shallow flats meet deep blue water.

The Max MegaWide format stores detailed bathymetric, coastal, and marine data on a compact microSD card that's compatible with a wide range of marine GPS plotters and sonar units. The card features C-MAP's signature detailed contour mapping, including fish-holding structure, shipwrecks, obstructions, and bottom composition data critical for targeting structure from the Carolinas through the Gulf to the Caribbean. MegaWide coverage eliminates the need to swap cards during longer trips, providing continuous navigation across a vast geographic footprint. The microSD format ensures quick data access while the cartridge's robust construction withstands the salt spray and humidity of extended time on the water.

This chart card works with most Lowrance, Simrad, and B&G marine displays that support C-MAP cartography, making it an ideal upgrade for existing systems or a core component of new installations. Anglers working the Atlantic seaboard, Gulf Coast shrimp boats, and Caribbean charter operations benefit most from its comprehensive coverage and precision bathymetry. Installation is straightforward—simply insert the microSD card into your compatible chartplotter—and the detailed waypoint and route management capabilities integrate seamlessly with your GPS workflow. For operators who fish multiple regions or run commercial operations across wide territory, this single cartridge eliminates dead zones and ensures continuous situational awareness from home port to destination.
