EchoMAP CHIRP 74sv Fishfinder/Chartplotter W/ GT51 TM Transducer (010-01803-01)

The easy-to-install, easy-to-use 7-inch EchoMAP CHIRP 74sv comes with GT51M TM transducer, high wide CHIRP sonar and Garmin CHIRP DownVü, the clearest scanning sonar on the water. The EchoMAP 74sv includes Quickdraw Contours software to instantly create your very own HD maps with 1-foot contours as you fish. Internal 5 Hz GPS can update position and heading 5 times per second. It even provides NMEA 2000 support for engine data, sensors, autopilots and more. Cords plug directly into the mount, allowing you to quickly install and remove your device from power and mount. Transom and trolling motor mounts included.

The Garmin CHIRP Difference - Precise Target Separation  

The built-in sonar of the 74sv comes with CHIRP sonar, the top-of-the-line sonar technology for fishing and recreational use. It seperate targets with extreme precision due to the extra energy placed on the target (much more than traditional sonar).The sonar-recording capability coordinates the timing of the sonar return w/ your boat's position and saves digital information, allowing you to playback on a computer using HomePort planning software. Share waypoints and routes between different devices with the data sharing cable.

Clearest Scanning Sonar on the Water 

Garmin CHIRP DownVü and CHIRP SideVü scanning sonars give you nearly photographic images of what’s below and to the sides of your boat. You clearly see structure, submerged objects and fish. Also supports Minn Kota and MotorGuide trolling motors with integrated transducers.

Garmin's SideVü

Much like DownVü, SideVü is high-frequency sonar that gives a clear image of fish or structures that are located to the sides of your boat. This true-to-life picture of what’s below the water’s surface helps identify the most ideal spots and structures for fishing, in a more lateral direction. With noise suppression providing for a super clean, high-resolution image, it’s easy to see where the best place to fish will be.

Preloaded BlueChart g2 Maps

echoMAP 74sv is preloaded with BlueChart g2 maps covering the coastal U.S. (East Coast, West Coast, Gulf of Mexico, U.S. and Canadian sides of the Great Lakes). It also includes all U.S. charts for the entire coastline & everything available on NOAA charts. In addition to the basic charts, tidal stations, currents, depth contours, IALA symbols & included fishing charts, offers smooth transitioning between zoom levels and more seamless continuity across chart boundaries. Customize your screens with Shallow Water Shading, which allows you to contour shade for all depth contours shallower than what you determine is your safe depth. Fishing charts emphasize bathymetric contours with less visual clutter on the display. And there’s also a choice of standard 2-D direct overhead or 3-D “over-the-bow” map views for easier chart reading and orientation.

Create Your Own HD Maps

Quickdraw Contours is a free, easy-to-use software feature installed on your echoMAP CHIRP 74sv. It instantly creates personalized HD fishing maps on screen with 1-foot contours. Tailor the maps as needed; you own them. Keep the data for yourself, or share it with Garmin or your friends. No special surveying expertise is required. You just fish while Quickdraw Contours creates maps. There’s no waiting around or sending your files away like other mapping software requires — your results appear instantly. Use with any Garmin Panoptix transducer, any HD-ID sonar, any CHIRP-enabled, Garmin DownVü transducer or NMEA 2000-compatible depth transducer. Have more than 1 sonar device installed onboard? Quickdraw Contours automatically selects the most capable sonar device to provide the very best results for you.

Heading and Position Refreshed 5 Times per Second

Fast, responsive 5 Hz GPS/GLONASS refreshes your position & heading 5 times each second to make your movement on the screen more fluid. It’s quick and easy to drop up to 5,000 accurate waypoints and find your way back to your secret fishing hot spots.

Add Panoptix LiveVü Forward Sonar

With LiveVü Forward your boat can be moving or stationary. Wherever your trolling motor is pointed, you will see live images of what is happening under the water. Watch your lure as it sinks, & see its depth and movement as you retrieve it. See it move in relationship to structures in the water. See fish swimming, reacting to your bait; if they attack, you’ll see & feel the hit. Once on the hook, watch the fight on your screen as it happens. With Panoptix LiveVü Forward, you can see it all come to life up to 100 feet away. 

Take Your echoMAP with You

When you’re off the water, it’s easy to keep your echoMAP safe and secure. The cords plug directly into the mount. This allows you to quickly install and remove your echoMAP from power and the mount.

Upgrade with the Best Garmin Maps on the Water

A single microSD card slot provides expandable memory for accessory map purchases such as LakeVü HD,LakeVü HD Ultra or BlueChart g2 Vision. LakeVü HD Ultra and BlueChart g2 Vision provide exclusive Garmin Auto Guidance, a technology that directs you to your hot spots. Based on the boat’s specifications, Auto Guidance instantly creates a visual path you can follow to avoid shallow water & other obstructions.

Enhanced Auto Guidance

Enter the location where you want to go & 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 & other obstructions.

With enhanced Version 2.0, you have access to more features &capabilities. You’re able to adjust the calculated Auto Guidance pathway by inserting “via” points at interim stops or landmarks along your desired route. Easily review hazard points along your calculated path. 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 LakeVü HD Ultra cartography.

GPX Waypoints Transfer

If you have waypoints, tracks or frequently used routes stored on another manufacturer’s GPS product - or on a Garmin handheld device - now it’s easier than ever to transfer those items to your new Garmin chartplotter, via industry-standard GPX software formatting. GPX is an open standard format for GPS data exchange across platforms and applications. With this easy-to-use interface technology, Garmin has taken “no waypoint left behind” to a whole new level of trade-up convenience.

Multiple Depth Range Shading

Designate up to 10 different depth ranges each with its own color. Makes it easier to view target depths at a glance.

Commission Autopilot from Chartplotter

You can handle the entire autopilot commissioning process from your chartplotter screen.
