Whether you're plotting a course along the rugged Pacific Northwest, chasing trophy fish in the Great Lakes, or navigating the intricate channels of the Florida Keys, this chart pack unlocks detailed hydrographic data for safe and confident voyages. Covering the full expanse of U.S. coastlines from the Atlantic to the Pacific, plus key Canadian regions, inland waterways, and island chains, it equips your chartplotter with the clarity needed for everything from weekend cruises to extended offshore adventures.
Imagine threading through the Inside Passage off Vancouver Island or anchoring in the Bahamas without second-guessing your position—these charts make it possible by blending high-resolution bathymetry with intuitive navigation aids.
This vast footprint means one card handles transcontinental trips, reducing the hassle of swapping maps mid-journey.
Enter your boat's draft and bridge clearances, and watch as the system plots an optimized route overlaid directly on your chart. It's a game-changer for unfamiliar bays or crowded marinas, saving time and reducing stress. Boaters report shaving hours off approach times to tricky anchorages like those in the San Juan Islands.
Customize up to 10 depth bands to highlight your safe operating range, with shallow areas shaded for quick visual alerts. Pair this with user-defined shallow shading to ghost out sandbars or shoals—essential for low-tide runs in the Chesapeake or skinny water fishing in the Everglades.
Finer than standard charts, these contours reveal drop-offs, humps, and ledges with pinpoint accuracy. Anglers use them to target structure in reservoirs, while cruisers appreciate the detail in narrow canals and swampy routes.
Downloadable through the ActiveCaptain app, this layers traditional NOAA views with lat/long labels over digital charts. It's like having a stack of paper charts in your plotter, bridging old-school reliability with modern tech for confident positioning in surveyed zones.
Powered by fused Garmin and Navionics data, these elements deliver sharper visuals and more reliable intel than standalone charts, trusted by commercial operators and recreational skippers alike.
Slip the microSD/SD card into your compatible Garmin chartplotter for instant access—no internet required offshore. Update via ActiveCaptain for the latest surveys, and overlay with sonar data for real-time bottom tracking. For fishing, zoom into 1-foot contours during dawn patrols; for cruising, rely on Auto Guidance to dodge no-go zones. Always cross-reference with local knowledge and current conditions for safest passage.

Unparalleled Coastal Chart Coverage
BlueChart g3 coastal charts provide industry-leading coverage, clarity and detail with integrated Garmin and Navionics data. Also included is Auto Guidance¹ technology, which uses your desired depth and overhead clearance to calculate routes and provide a suggested path to follow — overlaid onto your chart. NOAA raster cartography is also available as a free downloadable feature via the ActiveCaptain app. It gives your chartplotter paper chartlike views of NOAA-surveyed areas in which individual points of interest are labeled with corresponding longitude and latitude information. Worldwide coverage is available by regions as accessory cards or via download; each region is sold separately.
Auto Guidance Technology
The Auto Guidance feature¹ calculates a suggested route using your desired depth and overhead clearance.
Depth Range Shading
This feature displays high-resolution Depth Range Shading for up to 10 depth ranges so you can view your designated target depth.
Detailed Contours
BlueChart g3 features up to 1’ contours, which provide a more accurate depiction of the bottom structure for improved fishing charts and navigation in swamps, canals and marinas.
Shallow Water Shading
To aid in navigation, Shallow Water Shading allows map shading at a user-defined depth to give a clear picture of shallow waters to avoid.
NOAA Raster Cartography
This feature gives your chartplotter paper chartlike views of NOAA-surveyed areas in which points of interest are labeled with corresponding longitude and latitude information.
¹Auto Guidance is for planning purposes only and does not replace safe navigation operations
²Raster cartography cannot be viewed on echoMAP CHIRP and ECHOMAP Plus combos but can be viewed on mobile devices via the ActiveCaptain mobile app .
