Product Information
The Deeper Smart Sonar CHIRP+ 4 is a castable sonar for use from the bank, a boat, a bait boat or in winter. Its expert-trained AI identifies fish in sonar readings and shows fish marks on personal 2D and 3D maps.
It creates personal bottom-hardness and vegetation maps in 2D and 3D from its sonar data. Three CHIRP beam widths scan at 47°, 20° or 7°, while the 3D view shows depth, hills, slopes and other bottom features.
The 94g unit scans from 0.15m to 100m at up to 15 scans per second and connects by Wi-Fi at up to 120m, depending on the operating system and smartphone model. It comes with a hard carrying case, night fishing cover, USB-C charging cable and attachment bolts.
