Once cast into the water, the device automatically activates and begins scanning. The sonar data is transmitted wirelessly to your connected smartphone or tablet.
Understanding Sonar Data
The Fish Deeper app displays real-time sonar data, including depth, bottom structure and consistency, vegetation, and fish. The device uses two beam frequencies for comprehensive scanning:
- Wide Beam (55°): Ideal for quickly scanning large areas and locating fish schools.
- Narrow Beam (15°): Provides higher accuracy and detail for specific areas, useful for identifying individual fish and precise bottom structure.

GPS and Bathymetric Mapping
The built-in GPS allows you to create detailed bathymetric maps of the water body directly from the bank, boat, canoe, or kayak. As you troll or cast, the app records depth contours, building a comprehensive map of the underwater terrain.
- On-Shore Mapping: Cast the device and reel it in slowly to map the area in front of you.
- Boat/Kayak Mapping: Attach the device to your vessel and troll to create detailed maps of larger areas.
All your scans, maps, points of interest, photos, and notes are saved and accessible on the Fish Deeper app and the web plate-forme.
