Detailed FAQ Section

How accurate is the Humminbird Coastal Chart for Boats & Marine Engines?

The chart uses NOAA and hydrographic data to deliver precision mapping, offering up to 1-foot depth contours. It’s highly accurate in most coastal U.S. waters, including estuaries, inlets, and reef zones. Humminbird also layers exclusive sonar returns to improve accuracy where official charts may lack granularity. Users frequently report precise hazard warnings, soundings, and navigational aid placement even in remote bays.

Can I use the Humminbird Coastal Chart on any fishfinder?

No. The chart is only compatible with select Humminbird models including the APEX, SOLIX, and HELIX G3/G4 series. It requires an SD card slot and updated firmware to run CoastMaster efficiently. It’s not compatible with Lowrance, Simrad, Garmin, or other brands. For full functionality—especially SmartStrike—you’ll need a compatible Humminbird fishfinder with GPS and sonar enabled.

How do I update my Humminbird Coastal Chart?

Updates are delivered through the Humminbird FishSmart app or their PC software. You’ll need to insert the chart card into your computer using an SD adapter and follow on-screen instructions. Updates include chart refinements, new tide/current data, and depth contour corrections. It’s recommended to check for updates every 90–120 days or before any major boating expedition to ensure safety and accuracy.

What regions does the CoastMaster US Coastal Chart cover?

This version covers all U.S. saltwater coasts: the Atlantic (Maine to Florida), the Gulf of Mexico, and the Pacific Coast including California, Oregon, and Washington. It also includes key U.S. territories such as Puerto Rico. Charts are seamless and preloaded—no internet connection is required during use.

What should I do if my chart stops working?

Start by removing and reinserting the card. Ensure it’s clean and properly seated. If the issue persists, update the fishfinder firmware and check that it recognizes SD cards in general. You can also insert the chart into a PC to verify if the data is intact. If the card is unreadable or corrupted, contact Humminbird support for a potential replacement if under warranty. Avoid exposing the card to water or impact damage, as that voids most warranties.
