Get smart with a CHIRP chartplotter
Fish are smarter than humans, so if you're serious about catching any of them, it's essential to have the right electronic equipment on your boat. Garmin's echoMAP CHIRP 73sv chartplotter gives you clear view of the fish, thanks to Garmin CHIRP SideVü and CHIRP ClearVü sonar. The echoMAP CHIRP 73sv comes preloaded with over 17,000 U.S. lakes, rivers and reservoirs, and it's also fully compatible with your NMEA 2000 network.
See where you are and where the fish are.
Find those fish, sideways or down
The 73sv comes with a transducer for high wide CHIRP sonar, Garmin CHIRP SideVü, and Garmin CHIRP ClearVü. This ultra-accurate scanning sonar package gives you a nearly photographic image of what's below and beside your boat. You'll see the fish, plus the structures and submerged objects they're trying to hide behind.
A big, bright 7" display
Ultra-fast processing refreshes your position and heading 5 times per second, so onscreen movement looks fluid on the 7" high-contrast color display. You be able to see those fish in any lighting conditions, too, thanks to an auto-adjusting backlight. You can also drop up to 5000 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 73sv 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 Garmin or your friends. No surveying expertise is needed – you just fish and let your Garmin handle the map creation.
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.
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 CHIRP 73sv is preloaded with over 17,000 U.S. lakes, rivers and reservoirs, a number that includes more than 13,000 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 interstates, highways, roads and bridges; designated fishing areas; and marine-centric points of interest like docks, boat ramps, marinas, and campgrounds.
When you want to add additional maps in the future, just use the microSD™ card slot.
NMEA 2000 network-ready
When you integrate the CHIRP 73sv with your NMEA 2000® network, you'll be able to see engine data, check sensors, manage autopilot, and more. It also supports Panoptix LiveVü Forward Sonar, plus HD-ID support for Minn Kota® and MotorGuide® trolling motors with integrated transducers.
This Garmin device supports the FUSION-Link™ audio access system via the NMEA 2000 protocol. If you have an older version of this device, you can visit Garmin's website for a free download of the software update, or purchase the update on a preloaded data card shipped from Garmin.
Powerful and portable
It's easy to keep your echoMAP safe and secure when you're not on board. The cords plug directly into the mount, so you won't have to waste time plugging and unplugging wires. Just remove your echoMAP from power and the mount, then stow it away and go.

More details on the Garmin echoMAP CHIRP 73sv
Overview: The Garmin echoMAP CHIRP 73sv is a combination chartplotter and fishfinder. It has a loaded LakeVü HD map and a microSD slot for adding more specialized and detailed charts and maps that are available from Garmin. The echoMAP CHIRP 73sv has a 7" (diagonal) full color display, and can be mounted in a variety of ways. The fishfinder has a 500-watt, dual-frequency, dual-beam sonar transducer that lets you search for fish to a maximum depth of 2300 feet in fresh water or 1100 feet in salt water. 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 CHIRP 73sv has a 6" (wide) x 3.6" (high), 7" diagonal full color WVGA display with 800 x 480 pixels. It has a variable backlight adjustment (automatic or manual), with day and night color schemes that change automatically or you can set manually.
Keypad: The echoMAP CHIRP 73sv features a convenient keypad for operating the device. The keypad consists of eight buttons and a 4-way control:
- Power: The Power button turns the unit on and off. It also lets you quickly adjust the backlight or color, and disable the sonar, when you quickly press and release.
- Zoom: The "+" and "-" buttons let you zoom in and out of a view.
- 4-way Control: The 4-way control lets you scroll, highlight options, and move the cursor.
- Select: The Select button selects the highlighted option and acknowledges messages.
- Back: The Back button returns you to the previous screen, or to the home screen when held.
- Menu: The Menu button opens and closes the menu page.
- Mark: The Mark button saves the present location as a waypoint, allowing you to navigate to that point at a later time.
GPS/GLONASS: The echoMAP CHIRP 73sv 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 5Hz GPS/GLONASS 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 has preloaded US LakeVü Detail maps, which include over 17,000 US lakes, rivers, and reservoirs, including more than 13,000 HD lakes with 1-foot contours shoreline to shoreline. The map also has major highways, roads, and bridges, designated fishing areas, docks, boat ramps, marinas, and campgrounds. You can upgrade the unit by adding Garmin BlueChart g2 Vision HD maps and LakeVü HD Ultra maps of various US regions, available on microSD or download.
Quickdraw Contours: The echoMAP CHIRP 73sv features Quickdraw Contours software already installed on the device. This free software allows you to tailor the preloaded maps and create your own HD 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/SideVü 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 73sv consists of a display/control unit and a tilting bail mount with a quick release feature. The mount also includes a cradle for the display. 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.
NMEA 2000: The echoMAP CHIRP 73sv 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 CHIRP 73sv 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.
CHIRP Sonar: The echoMAP CHIRP 73sv is equipped with the 500-watt Garmin CV52HW-TM High Wide band transducer which has CHIRP traditional sonar, CHIRP ClearVü sonar, and CHIRP SideVü sonar, some of the most sophisticated sonar technologies available for boaters and fishermen. 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. Using traditional sonar, the transducer supports 50kHz, 77kHz, and 200kHz for returns from depths of up to 2300 feet in fresh water (1100 feet in salt water), plus CHIRP ClearVü/SideVü sonar at 260kHz, 455kHz, and 800kHz for greater accuracy in shallower depths down to 500 feet (ClearVü), as well as 500 feet left and right (SideVü).
Note: The transducer comes with both a transom mount and a trolling motor mount.
Sonar Views: The echoMAP CHIRP 73sv'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-screen: The split-screen sonar views let you view different combinations of sonar data simultaneously, such as traditional sonar and ClearVü.
- 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.
Chart Views: The echoMAP CHIRP 73sv has US LakeVü HD Maps. The display will let you view these maps in several ways:
- Navigation Chart: This 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.
- Perspective 3D Chart: The 3D chart provides a view from above and behind your vessel, and provides a visual navigation aid. This view is helpful when navigating tricky shoals, reefs, bridges, or channels, as well as entry and exit routes in unfamiliar harbors.
- Fishing Chart: The Fishing Chart provides a detailed view of the bottom contours and depth surroundings. Navigational data is removed, and the bottom contours are enhanced for depth recognition. It is best for offshore deep-sea fishing.
- Other Views: With some premium charts, you can use the Mariner's Eye 3D view for more detailed, 3-dimensional representations of your location. The Fish Eye 3D view shows an underwater view with greater detail of the sea floor, according to the chart information. With an optional sonar transducer, you can see suspended targets (such as fish) indicated as bright colored spheres.
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.
