Offline Maps
Download maps before you leave the dock. Use them with no internet connection.
Download Before You Go
Select the regions you fish most and download them while you have WiFi. The app stores both visual map tiles and depth data tiles locally, so everything works exactly the same whether you're connected or not.
Region-Based Downloads
Maps are organized into downloadable regions covering the entire Hawaiian island chain. Pick just the areas you need, or download everything for full coverage. Each region shows its download size so you can manage your storage.
Manage Your Storage
See exactly how much space each downloaded region uses. Delete regions you no longer need and re-download them anytime. The app uses a smart cache to maximize storage efficiency.
Always-Offline Features
Even without downloading map tiles, these features always work offline with no setup required:
- All saved placemarks and their details
- GPS tracks and route recording
- All map layers (fishing zones, ORMA areas, whale sanctuary, and more)
- Points of interest (harbors, FAD buoys, dive spots, lifeguard towers, and more)
- Distance measurements
- Navigation to waypoints
