Collection: Cartography | Garmin BlueChart Vision

Garmin BlueChart g3 Vision HD charts cover specific stretches of US coastline on microSD and SD cards, formatted for compatible Garmin chartplotters. The selection spans from North Maine and Cape Cod through the Mid-Atlantic to Jacksonville and the Bahamas, with Gulf Coast coverage from the Florida Keys to Brownsville. Alaskan waters are also covered, from North Slope and Bristol Bay to Southeast Alaska around Wrangell and Dixon Entrance. Cards vary in coverage size, with some bundling broader coastal ranges and others focusing on tighter local areas.

Before buying, confirm that your Garmin chartplotter accepts microSD or SD cards and supports the BlueChart g3 Vision format. Coverage boundaries are the critical check: each card covers a defined zone, so verify that a single card encompasses your full cruising area. Boaters who stay within one region will find a single card sufficient, while those making longer passages or crossing into adjacent zones should review coverage maps to avoid gaps on the water. Outdoors Marine is an authorized Garmin dealer, and every card comes with the full manufacturer warranty.
