With fewer buttons to push and fewer operational steps to navigate, the simplified menu format on the GPSMAP 420 makes it easy for you to see and select the data you want to access on-screen. The 420s includes a combo sounder that can scan as deep as 1500 feet/ 457 meters (with dual frequency transducer) to clearly paint depth contours, fish targets, structure, etc. Both models are CANet capable, allowing sounder data to be shared with other plotter displays.
