When you're ready to drive home, take your 478 out of its marine mount and pop it into the automotive mount in your vehicle. Then press one button, and your 478 is ready to navigate you on the roads, with turn by turn directions and voice prompts that take you straight to your destination. The 478 is preloaded with detailed City Navigator maps for all of North America and contains over 6 million points of interest, including hotels, restaurants, gas stations, marinas, attractions and more. View vital weather data, including NEXRAD radar, storm cells, wind speeds, surface temperatures, forecasts and more than a dozen other weather attributes, so you can enjoy the water without worrying about the weather.
For serious fishing, pair the 478 with the GSD™ 21 remote sounder, which offers 4,000 watts of power peak-to-peak (500 watts RMS) with a dual-frequency transducer (purchased separately).
