CHIRP fishfinders are displays that contain built-in sonar circuitry. The CHIRP transducer plugs directly into the back of the display and there is no need for an external sounder box.
Most integrated CHIRP fishfinders support single-band transducers only. Dual-band transducers usually require a Multi-Function Display (MFD) with an external sounder connected via high-speed cable to the display.
