Get smarter with a Garmin chartplotter
If you're serious about finding fish, you need the right electronic equipment on your boat. Garmin's ECHOMAP UHD 74cv chartplotter gives you clear view of the fish, thanks to CHIRP ClearVü sonar. This chartplotter comes preloaded with BlueChart g3 maps covering the coastal U.S., and it's also Wi-Fi-enabled and fully compatible with your NMEA 2000 network.
Find those fish, sideways or down
This transducer bundle includes Garmin's GT24UHD-TM Ultra High-Definition scanning sonar transducer, an all-in-one powerhouse that gives you the highest resolution ClearVü scanning sonar images around, plus high wide CHIRP traditional sonar for super-clear target separation and definition.
You'll see remarkably detailed images of fish and structures up to 200 feet below your boat with 800 kHz ClearVü sonar. The all-in-one design is easy to install and includes transom and trolling motor mounts.
High-contrast color display
Ultra-fast processing refreshes your position and heading 5 times per second, so onscreen movement looks fluid on the 6.2" high-contrast color display. You'll be able to see those fish in any lighting conditions, thanks to an auto-adjusting backlight. You can also drop up to 5,000 waypoints and find your way back to your favorite fishing spot.
Easy transfer of waypoints
If you have waypoints, tracks or frequently used routes stored on another manufacturer's GPS product — or on a Garmin handheld device — you can transfer those items to your new Garmin chartplotter, via GPX Waypoints Transfer.
Make your own maps
The UHD 74cv includes preloaded Quickdraw Contours software that lets you create your own HD maps with 1-foot contours. You'll own the maps, so you can keep the data to yourself or share it with your friends. No surveying expertise is needed — you just fish and let it handle the map creation. Pair the built-in Wi-Fi with Garmin's free ActiveCaptain™ app to get notifications, share maps, and more.
Smart features for smart boaters
Enter a desired location and let Garmin Auto Guidance technology search relevant charts to create a safe virtual pathway on the display that helps you avoid low bridges, shallow water, and other charted obstructions. You can adjust the pathway by inserting “via” points at interim stops or landmarks along the way. You can adjust the pathway by inserting “via” points at interim stops or landmarks along the way.
Color coded cues
If you need even more "at a glance" info, you can designate up to 10 different depth ranges and assign a unique color to each one. If you're coming to this Garmin from a different chartplotter, this could be a great way to retain the visual cues you're used to.
Preloaded LakeVü HD maps
The ECHOMAP UHD 74cv is preloaded with over 17,000 U.S. lakes, rivers and reservoirs, including more than 6700 HD lakes with 1-foot contours shoreline-to-shoreline.
LakeVü HD gives you remarkably detailed views of underwater features, plus Safety Shading that allows you to designate a minimum depth. You'll also be able to get info on interstate highways, roads and bridges; designated fishing areas; and marine-centric points of interest like docks, boat ramps, marinas, and campgrounds.
Just use the microSD™ card slot when you want to add additional maps in the future, or you can purchase new charts through Garmin's free ActiveCaptain app.
NMEA 2000 network-ready
When you integrate the 74cv with your NMEA 2000® network, you'll be able to see engine data, check sensors, manage your autopilot, and more. It also supports Panoptix LiveVü Forward Sonar, plus HD-ID support for Minn Kota® and MotorGuide® trolling motors with integrated transducers.
Powerful and portable
Keeping your ECHOMAP chartplotter safe and secure when you're not on board is remarkably easy. The cords plug directly into the mount, so you won't have to waste time plugging and unplugging wires. Just remove your Garmin from power and the mount, then stow it away and go.

More details on the Garmin ECHOMAP™ UHD 74cv
Overview: The Garmin ECHOMAP UHD 74cv (Garmin part # 010-02331-01) is a combination chartplotter and fishfinder. It comes preloaded with Garmin's exclusive BlueChart g3 coastal charts and LakeVü g3 inland maps, both with integrated Navionics® data and Auto Guidance technology. In addition, a built-in microSD slot lets you add more specialized and detailed charts and maps that are available from Garmin. The ECHOMAP UHD 74cv has a 7.0" (diagonal) full color touchscreen display that can be mounted in a variety of ways. The fishfinder has a 500-watt (RMS), dual-frequency, dual-beam sonar transducer that lets you search for fish to a maximum depth of 1900 feet. The unit has a water rating of IPX7, and can withstand being splashed with water without worry, but unsuitable for prolonged immersion.
Display: The ECHOMAP UHD 74cv has a 6.1" (wide) x 3.4" (high), 7.0" diagonal full color touchscreen WVGA display with 400 x 800 pixels. It has a variable backlight adjustment (automatic or manual), with day and night color schemes that change automatically or you can set manually. With the large display, you can create custom combination pages with up to several different functions on the display at once.
Keypad: In addition to touchscreen controls, the ECHOMAP UHD 74cv features several buttons for operating the device. The keypad consists of a power button, a plus/minus control for zooming in and out of a chart or view, and shortcut keys, numbered 1-4, that can be assigned to an active screen so you can open it instantly when pressed.
Global Positioning System: The ECHOMAP UHD 74cv has a built-in GPS receiver that collects data from overhead satellites to establish your current location. The GPS signal strength is indicated on the top of the screen in a bar graph (5 bars maximum). The device is equipped with a 5 Hz GPS receiver which refreshes its position and heading 5 times per second. In addition, the unit coordinates the timing of the sonar return in relation to the boat's position to give you amazingly accurate waypoints or for pinpointing fishing hotspots.
Charts and Maps: The unit is preloaded with Garmin's BlueChart g3 maps, which covers the coastal US, including the East and West Coasts, the Gulf of Mexico, and the US and Canadian sides of the Great Lakes. It also includes Garmin's LakeVü g3 maps, with coverage of more than 17,000 inland lakes with up to 1' contours and Depth Range Shading for clearer lake floor view, and enabling you to view your target depth at a glance. Additional maps are available on microSD or download.
Quickdraw Contours: The ECHOMAP UHD 74cv features Quickdraw Contours software already installed on the device. This free software allows you to tailor the preloaded maps and create your own maps on the screen. While you fish, Quickdraw Contours creates the maps based on the sonar results from an attached compatible transducer (including the supplied ClearVü transducer). Other compatible transducers include any Garmin Panoptix, HD-ID, DownVü, or NMEA 2000-compatible. If you are using more than one transducer, you can choose which sonar device gives you the best results.
Mounting Options: The 74cv consists of a display/control unit and a tilting bail mount with a quick release feature. When you come off the water, just disconnect the display/control unit from the bail mount and go. No plugging or unplugging wires from the unit itself, as the cables plug into the quick-disconnect bail mount. You can also flush-mount the display/control unit into your dashboard. A flush-mount template helps you make the cut into the mounting location. A self-adhesive rubber gasket is provided for flush-mount applications. A snap-on cover protects the display/control unit when you're not on the water.
NMEA 2000: The ECHOMAP UHD 74cv can be connected to an NMEA 2000 network which can carry power and data along the same cable. If your vessel has an existing NMEA 2000 network, it should already be connected to power. The device can share data from other NMEA 2000 devices, such as sensors or a VHF radio, plus you may also be able to view fuel and engine data on the display. The necessary cables and connectors are sold separately.
Wi-Fi: The unit has built-in Wi-Fi that allows you to connect to the free Garmin ActiveCaptain app on your mobile device. ActiveCaptain has a OneChart feature for accessing and updating all of your charts and maps from your smartphone or tablet, as well as purchase new ones to use on the chartplotter. You can also receive notifications of phone calls and texts on the unit's display. ActiveCaptain also lets you keep in touch with fellow boaters to get first-hand information about points of interest near your route or destination. Separate ActiveCaptain and Mobile Quickdraw communities are available for feedback or for sharing your Quickdraw Contours data. The Garmin ActiveCaptain app is compatible with devices running Android 5.0 and up, or Apple iOS 11.0 or later.
CHIRP Sonar: The ECHOMAP UHD 74cv is equipped with the 500-watt Garmin GT24UHD-TM Ultra High-Definition scanning sonar transducer. This single transducer provides the highest resolution ClearVü scanning sonar images with remarkably clear target separation and definition. You'll be able to view incredibly detailed images of fish and structure below your boat with 800kHz ClearVü sonar. Compared to standard sonar, which sends one frequency at a time, CHIRP (Compressed High-Intensity Radiated Pulse) sends a continuous sweep of frequencies within a range from low to high. As a result, CHIRP sonar creates much greater target separation and crisper fish arches. Traditional sonar transducers emit a conical beam, while ClearVü sonar casts two narrow beams, similar to that of a copying machine.
Note: The transducer comes with both transom and trolling motor mounts.
Sonar Views: The ECHOMAP UHD 74cv's sonar display scrolls from right to left to show the sonar readings from the transducer. The bottom depth is displayed in large numerals, along with the water temperature, and water speed. The unit has an adjustable depth range, and the depth scale is shown at the bottom of the screen, along with the transducer frequency. You can choose from four basic styles of sonar views:
- Full Screen: You can view in full screen your choice of traditional or ClearVü sonar.
- Split-zoom: The split-zoom view shows a full-view graph of sonar readings, and a magnified portion of that graph on the same screen.
- Split-frequency: In the split-frequency sonar view, one side of the screen shows a full-view graph of high frequency sonar and the other side shows a full-view graph of lower frequency sonar data.
- ClearVü: The ClearVü provides a detailed picture of the fishing environment around the boat in a detailed representation of structures the boat is passing over.
Flasher Views: A Flasher View shows sonar information on a circular depth scale to indicate what is beneath your boat. Zero depth is shown at the top, and the depth progresses clockwise, according to the scale inside the ring. The depth at your present location is shown in the center of the ring. Sonar returns are indicated in a color scheme: Yellow (strongest), Orange (strong), Red (weaker), Blue (weakest), and White (no return).
- Frequencies Supported:
- Traditional: 77/200
- Ultra High-definition ClearVü: 800 kHz (800-840 kHz)
- CHIRP ClearVü: 455 kHz (435-475 kHz)
- Transmit Power:
- Traditional: 500 watts (RMS)
- ClearVü: 500 watts (RMS)
- Maximum Depth:
- Traditional: 1900 feet
- ClearVü: 1100 feet
- Transducer Dimensions (with transom mount): Width 2.563", Height 3.771", Depth 7.125"
Chart Views: The ECHOMAP UHD 74cv has BlueChart g3 Coastal maps and LakeVü g3 inland maps pre-loaded into its memory. The Navigation Chart view shows the navigation data on the included maps with details including buoys, lights, cables, depth soundings, marinas, and tide stations in an overhead view. With optional premium charts, you can get a Fishing Chart view or several 3D views, including Perspective 3D, Mariner's Eye 3D, Fish Eye 3D, and Relief Shading.
Auto Guidance: The pre-loaded maps are integrated with Navionics® data and Auto Guidance technology to help you navigate to your destination. After you enter your desired destination, Auto Guidance scans your chart data, such as water depth and known obstacles, and uses your desired depth and overhead clearance to calculate a suggested path. You can manually adjust the path during navigation, if desired.
Note: Auto Guidance is designed for planning purposes only, and should not replace safe navigation operations.
Waypoints: You can mark and save up to 5000 waypoints into the unit's memory. Waypoints can be marked at your present location, or you can enter the coordinates to a waypoint at a different location. Each waypoint can be saved with a name, symbol, depth, and comments. Once a waypoint has been saved, you can select and navigate to its location. You can also measure the distance to the waypoint on the Waypoint Map.
Routes: A route is a sequence of waypoints or locations that leads you to your final destination. You can create and immediately navigate a route on the Navigation chart or the Fishing chart, or create a route by putting together a series of waypoints and turns. Up to 100 routes can be created and saved in the device.
Tracks: A track is a recording of the current path of your boat. You can designate a color for each track to differentiate them from each other. Tracks are created by automatically marking the current location at a set interval. The interval can be adjusted--recording more frequent plots increases accuracy, but fills up the track log quicker. You can also record tracks by the distance between points, or the variance from your course. You can log and save up to 50 tracks with 50,000 points.
Boundaries: Boundaries allow you to remain in or avoid designated areas in a body of water. You can set up an alarm to alert you when you enter or exit a boundary. Boundaries can be areas, lines, or circles on the map. Saved tracks and routes can also be converted into boundary lines.
Other Available Data: The ECHOMAP UHD 74cv lets you view data on tides, currents, and celestial conditions for a specifice date and time:
- Tide Station Info: You can view tide height, and the times when the next high and low tides will occur.
- Current Station Info: You can view current speed and the level of the current.
- Celestial Info: Information regarding sunrise, sunset, moonrise, moonset, moon phase, and the approximate sky view location of the sun and moon can be viewed on the screen.
