Mapped by You, Powered by AI. Equipped with AI-powered fish detection, personal bottom hardness, and weed maps in 2D & 3D, along with 3-frequency CHIRP technology. The most advanced castable sonar ever made. AI Powered Fish Detection: No more guessing what is on your sonar screen. CHIRP+ 4's built-in AI interprets raw scan data in real time, automatically identifying fish from noise, so now you can focus on fishing and not decoding readings. With CHIRP+ 4 you will see detected fish not only on your live scanning but also on your saved maps in both 2D and 3D. View past fish marks anytime. Multi-Layered Personal Maps: Scan the depths and map out the bottom in great detail. Create your own detailed personal maps that reveal underwater contours and structure, helping you understand and interpret every fishing spot. Also, you can generate personal bottom hardness maps in 2D and 3D, revealing exactly where hard gravel transitions into soft mud or silt. Map weeds and all aquatic vegetation in detailed 2D and 3D layers, revealing weed edges, pockets, gaps and clear areas. Powerful and Variable CHIRP Technology: Choose between 3 beam widths of wide, medium and narrow and explore the bottom structure in rarely seen clarity with whichever option suits your needs. Analyze lakebed features and hardness, vegetation and depth within 100 meters, all in one cast. 4x more pixels means distinguishing features such as fish, snags and drop-offs in shallow water up to 5 meters, has become significantly easier.
