Garmin GPSMAP 721xs Sounder

Key Features and Benefits: Super-fast 10 Hz GPS/GLONASS With the integration of a 10 Hz GPS/GLONASS receiver, the 721xs refreshes position and heading up to 10 times per second. It displays constant and fluid on-screen location and proves to be incredibly accurate when marking waypoints and navigating. Advanced echo HD-ID sonar In addition to the integrated receiver, GPSMAP 721xs also allows for sonar recording. This feature coordinates the timing of the sonar return in relation to the boat's position - so every one of the available 5,000 waypoints will be accurate and precise. It's an absolute must when locating and pinpointing the next hot fishing spot. Spread-spectrum CHIRP sonar When used with a compatible CHIRP transducer, GPSMAP 721xs displays crystal-clear sonar images to help find the next hidden fishing spot, ship wreckage or diving location. With the Spread-Spectrum technology, you can see target separation and resolution at extraordinary depths, and dial into specific frequencies to target certain species of sport fish. Bottom contours are more visible, and signal noise can be suppressed at greater depths to provide a more timely interpretation of what's below for safer navigation and better fishing.
