C-MAP NA-M325 Max Wide microSD Gulf of Maine Bathymetric

The C-MAP NA-M325 Max Wide microSD Gulf of Maine Bathymetric chart is purpose-built for serious anglers and boaters navigating the challenging waters of the Gulf of Maine and surrounding Atlantic coastal regions. This compact microSD cartridge delivers detailed bathymetric data—precise bottom contours, depth measurements, and structure information—that transforms your electronics into a true fish-finding instrument. Whether you're targeting striped bass, bluefin tuna, or groundfish in Maine's productive waters, accurate bathymetry is the difference between a blank day and a successful trip.

This microSD format ensures broad compatibility with modern chartplotters, multifunction displays, and integrated navigation systems found on contemporary fishing vessels and recreational boats. The Max Wide coverage extends your situational awareness across a wider geographic footprint, reducing the need for multiple chart cards and keeping your electronics uncluttered. High-resolution bathymetric contours reveal subtle breaks, ledges, and drop-offs where fish congregate—critical structure that surface charts alone cannot convey. The lightweight, durable design (0.18 lbs) makes it easy to store and swap between units without adding weight or bulk to your wheelhouse.

Professional guides, offshore tournament anglers, and coastal weekend warriors depend on C-MAP bathymetric data to plan routes, identify productive bottom structure, and maximize lure presentation. This chart is essential for anyone operating GPS-enabled fishfinders, autopilots, or integrated marine navigation platforms compatible with microSD media. Installation is straightforward: insert the card into your compatible device and verify coverage display on your chart screen. For Gulf of Maine operators and extended Northeast coastal fishing, this is a core navigation and fish-location tool that pays dividends in accuracy and confidence on the water.
