The Garmin echoMAP 70dv combination chartplotter/sonar offers amazing features such as advanced HD-ID sonar and DownVu scanning sonar for a nearly photographic sonar view under your boat on a 7 inch touchscreen with pinch-to-zoom. Its 10Hz GPS /GLONASS receiver updates your position and heading 10 times per second to display fluid vessel movement and dramatically improve your ability to accurately mark and navigate to 5000 waypoints. The 70dv also includes sonar-recording capability that coordinates the timing of the sonar return with your boat’s position and saves digital information on the map. The 70dv can wirelessly connect to Apple iPhone or iPad for Garmin Helm or BlueChart Mobile. Includes all-in-one transducer and preloaded Garmin LakeVu HD maps.
