Garmin GPSMAP 400 and 500 Series Chartplotter/Sounder Combos

The Garmin GPSMAP 400/500 Chartplotter/Sounder Combos have a high-sensitivity GPS receiver and a powerful dual beam or dual frequency transducer for determining position, depth contours, fish, and structure and illustrating them on the bright 4" or 5" color display. The high-speed digital design provides you with faster map drawing and panning speeds, while features like Ultrascroll, AutoGain, and Seethru technology make your sounder data incredibly easy to decipher.
