Traditional chirp, Ultra High-Definition ClearVu, and SideVu scanning sonars are all part of the fish-finding mix when you get the Echomap Ultra 106sv. This 10-inch, key-assisted touchscreen unit also can handle the Panoptix sonar line, if you add another transducer. Another? Yes, because it already comes bundled with an all-in-one transducer that can handle everything else. It’s also preloaded with Garmin BlueChart g3 coastal charts and LakeVu g3 inland maps.
