AI-Powered Fish Detection
No need to guess what's on your sonar screen. CHIRP+ 4's built-in AI interprets raw scan data in real time, automatically identifying fish from noise, so you can focus on catching, not decoding readings.
AI performance steadily improves with continuous updates
Fish Locations on Your Maps
With CHIRP+ 4, you’ll see detected fish not only during live scanning but also on your saved maps in both 2D and 3D. View past fish marks anytime.
Fish icons appear directly on your 3D bathymetric map for spatial awareness.
Multi-Layered Personal Maps
Scan the depths and map out the bottom in great detail. Create your own detailed personal depth maps that reveal underwater contours and structure, helping you understand every fishing spot.
Powerful and Variable CHIRP Technology
Choose between 3 beam widths and explore the bottom structure in rarely seen clarity with whichever option suits your needs. Analyze lakebed features/hardness, vegetation, and depth with 100 meter, all in one cast!
4x more pixels in shallow waters
4x more pixels means distinguishing features, such as fish, bottom drop-offs, and snags, in depths of up to 5 meter, become significantly easier for any angler.
Built-in triple beam system
Choose between 3 beam widths and explore the bottom structure in rarely seen clarity with whichever option suits your needs.
