What units are used in the depth charts?

Fishbox depth charts use different units depending on the chart type:

  • NOAA charts (included with Premium, U.S. coastlines & Great Lakes): display meters only. The unit cannot be changed.

  • Navionics charts (separate purchase, iOS only): display feet and inches only. The unit cannot be changed.

Please always verify which chart you are using, as the measurement units differ between NOAA and Navionics, ensuring accurate depth readings for your trip 🌊
