Clearest Scanning Sonar on the Water - Garmin DownVü scanning sonar gives you a nearly photographic image of what passes below your boat. Garmin SideVü scanning sonar gives you a crisp, clear view of what lies up to 750-feet off to each side of your boat. You clearly see structure, submerged objects and fish! Traditional Garmin HD-ID sonar and both DownVü and SideVü scanning sonar are combined into one transducer. Also provides HD-ID support for Minn Kota and MotorGuide trolling motors with integrated transducers. The echoMAP 73sv also includes sonar-recording capability that coordinates the timing of the sonar return with your boat's position and saves digital information for playback on a computer using free HomePort™ planning software. Use the User Data Sharing Cable to share waypoints and routes between multiple devices.

Preloaded LakeVü HD maps - These highly detailed freshwater maps include 17,000+ U.S. lakes, rivers and reservoirs. Included in those are more than 6,700 HD lakes with 1-foot contours shoreline to shoreline; excellent detail of underwater features plus Safety Shading that allows you to designate a minimum depth; interstates, highways, general roads and bridges; designated fishing areas; and points of interest, such as docks, boat ramps, marinas and campgrounds.

Heading and Position Refreshed 5 Times Per Second - Fast, responsive 10 Hz GPS/GLONASS refreshes your position and heading 10 times each second to make your movement on the screen more fluid. It makes dropping up to 5,000 accurate waypoints — and finding your way back to them — quick and easy.

Upgrade with the Best Maps on the Water - Two SD™ card slots provide expandable memory for accessory map purchases, such as LakeVü HD Ultra with Max Def Lakes or BlueChart g2 Vision that add Garmin patented Auto Guidance and other great features.

Enhanced Auto Guidance - Just enter the location where you want to go and patented Garmin Auto Guidance technology instantly searches through relevant charts to create a safe virtual pathway on the display that helps you avoid low bridges, shallow water and other charted obstructions en route.

Better still, with enhanced Version 2.0, you now have access to even more features and capabilities. You’re able to adjust the calculated Auto Guidance pathway by inserting “via” points at interim stops or landmarks along your desired route. You can easily review hazard points along your calculated path. And you can even engage your compatible Garmin autopilot to follow the Auto Guidance route, automatically. Other 2.0 enhancements give you the ability to calculate arrival times at any point on your route (great for timing arrivals to correspond with bridge openings and other time-critical events). Better still, you can now save your plotted Auto Guidance paths for future navigation by backing them up on an SD™ card with your BlueChart® g2 Vision® or Lake Vü™ HD Ultra cartography (BlueChart® g2 Vision® or LakeVü™ HD Ultra SD card is required for this technology).
