Discover Unmatched Detail for West Coast Waters

Whether you're chasing trophy fish off the rugged California coastline, navigating the intricate channels of Puget Sound, or exploring hidden gems in Arizona's desert lakes, reliable mapping is your best ally on the water. This microSD card unlocks crystal-clear cartography tailored for the diverse terrains of the U.S. West—from Hawaii's volcanic shores to Wyoming's remote reservoirs. Blending Garmin's precision engineering with Navionics' renowned data, it delivers a seamless experience that feels intuitive yet packed with pro-level insights.

Imagine plotting a safe route past rocky outcrops in Oregon's coastal inlets or zeroing in on prime structure in Idaho's deep lakes. With high-resolution bathymetry down to half-meter contours, every submerged ledge and drop-off stands out, helping you anchor confidently or cast precisely. Boaters rave about how these maps transform day trips into epic adventures, saving time on planning and boosting confidence during tricky conditions.

Expansive Coverage Across the West

Spanning thousands of miles of coastline and inland waterways, this chart set captures the essence of the region:

• Arizona's expansive lakes like Roosevelt and Powell
• California's iconic bays from San Diego to San Francisco
• Colorado's high-altitude reservoirs
• Idaho, Montana, and Wyoming's pristine mountain lakes and rivers
• Nevada's hidden oases
• North and South Dakota's river systems

From bustling marinas to secluded coves, the coverage emphasizes navigable paths, hazards, and hotspots that matter most to West Coast explorers.

Smart Navigation That Thinks Like You Do

Leave guesswork behind with dock-to-dock guidance that factors in your boat's draft, height, and real-world routes used by thousands of locals. It suggests efficient paths through narrow passages, avoiding no-go zones automatically. Customize shallow water shading to spotlight depths under 5 feet—or whatever suits your vessel—making it easier to hug shorelines without drama.

Pair it with real-time SonarChart Live to build your own HD maps as you motor, revealing fresh bottom details from recent passes. For those paper-chart nostalgics, overlay NOAA raster images for that classic reference layer, all accessible right from your plotter.

Fishing Smarter, Not Harder

Anglers targeting West Coast species like halibut in Washington or bass in California reservoirs love the fishing range tool. Dial in your ideal depth bracket—say, 20-40 feet—and watch it glow on screen, highlighting structure-rich zones. SonarChart's 1-foot contours expose subtle contours where fish stage, from steep drop-offs in the Pacific to weedy flats in inland waters.

Pro tip: Combine community edits from fellow boaters for insider marks on hot bites or gear-up ramps, turning your plotter into a local knowledge hub without needing VHF chatter.

Stay Current with Effortless Updates

Fresh data keeps you ahead of changes like new buoys or dredging. Sync wirelessly through the Boating app or ActiveCaptain for daily refreshes, ensuring your charts reflect the latest from survey boats and user reports. The first year rolls in seamlessly, with options to extend coverage annually.

Seamless Integration with Your Garmin Gear

Designed for plug-and-play simplicity on popular models, it powers up instantly to overlay advanced layers without fuss. Reliable across series like ECHOMAP UHD, Ultra, GPSMAP Touch, and beyond, it's the upgrade that maximizes your investment in Garmin tech.
