FIND BETTER WATER
- Explore HD bathymetry, relief shading, bottom hardness, and species layers including Red Snapper and Red Grouper maps
- Review commercial fishing track history, traffic footprints, and inferred activity to spot repeat fishing patterns
- Save promising areas as waypoints or turn vessel tracks into routes
BUILD YOUR OWN SYSTEM
- Log catches with photos and automatic weather context so you can learn which conditions produce fish for you

more I’ve been using this for a couple months now. You can actually see more detail than any of the other chart viewers. Great for finding new fishing spots.

The super high resolution on this app has helped me find new ledges that no one else was fishing yet, so the spots were loaded with fish! Well worth the value!
