CHIRP+ 4, powered by expert-trained AI, helps distinguish fish from sonar noise. This reduces guesswork, especially in situations where interpreting sonar readings can be challenging. AI Fish Detection – Automatically identify fish in your sonar readings and view them on your personal 3D maps, reducing the need to interpret raw sonar data. Key Features-Benefits Bottom Structure & Vegetation – Discover bottom structure and vegetation built from your own precise sonar data and locate the most productive fishing spots.Personal Vegetation and Bottom Hardness Maps available in both 2D and 3D. Triple Beam System – Choose between 3 beam widths and explore the bottom structure in rarely seen clarity with whichever option suits your needs. 3D Clarity – View bottom features like structure, depth, hills, and slopes in 3D with exceptional clarity.
