Available with or without a sonar transducer

The ECHOMAP Ultra 2 126sv features built-in traditional CHIRP sonar capability, along with Ultra High-Definition ClearVü and SideVü scanning sonars, so it'll be ready when you add a compatible Garmin transducer, like the GT56UHD-TM. Vivid color palettes allow you to distinguish between fish and underwater structures easily.

Garmin's GT56UHD-TM transducer gives you remarkably clear, detailed images up to 200 feet below and 500 feet around the boat. You'll see fish, plants, and structures, and you'll even be able to tell the difference between big fish and little fish. The transducer delivers Ultra High-Definition ClearVü and SideVü scanning sonar images to the chartplotter, and it works with high wide CHIRP traditional sonar. If you purchase the Ultra 106sv package including the transducer, it also includes transom and trolling motor mounts for an easier installation.

Coastal and lake maps ready for use

The ECHOMAP Ultra 2 126sv's large display means the preloaded Garmin Navionics+ inland and coastal integrated maps will show up big and bright. Coverage includes the coastal U.S. (East Coast, West Coast, Gulf of Mexico, U.S. and Canadian sides of the Great Lakes), Alaska, Hawaii, and coastal British Columbia. You also get U.S. charts for lakes and other inland waterways. Navionics+ also features Garmin's new Auto Guidance+ technology, which quickly calculates the best route between your boat and your destination that won't get you hung up on obstacles, shallow waterways, overhead impediments, or sharp turns.

This ECHOMAP comes with a 1-year Navionics+ subscription for downloadable daily updates and more. You can also use the microSD™ card slot when you want to add more maps, or you can purchase new charts through Garmin's free ActiveCaptain® app.

Make your own maps

The ECHOMAP Ultra 2 126sv 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 with select Garmin ECHOMAP devices. No surveying expertise is needed — you just fish and let it handle the map creation. You can pair the built-in Wi-Fi with Garmin's free ActiveCaptain app to get notifications, share maps, plan trips, and more.

Add more enticing maps

Optional Garmin Navionics Vision+™ premium cartography brings a fresh look to your ECHOMAP's maps. This service delivers high-resolution relief shading, satellite imagery, sonar imagery, and much more. A subscription to Garmin Navionics Vision+ is required to receive the content, and some content is only available through the ActiveCaptain app; visit Garmin's website for more details.

NMEA 2000 network-ready

When you integrate this Garmin ECHOMAP chartplotter 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.

Works with Fusion receivers

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.

Stow it away

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.

Chartplotting Features


Overview: The Garmin ECHOMAP Ultra 2 126sv (Garmin part # 010-02882-01) marine chartplotter comes preloaded with Garmin Navionics+™ inland and coastal maps of the United States and Coastal Canada. In addition, it has two built-in microSD slots to let you add more specialized and detailed charts and maps that are available from Garmin. It has a large 12.1" (diagonal) full color touchscreen display that can be mounted in a variety of ways. ECHOMAP Ultra 2 126sv includes the GT56UHD-TM Ultra High-Definition sonar transducer with traditional and scanning sonars that let you search for fish to a maximum depth of 800 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 Ultra 2 126sv has a sunlight-readable 10.3" (wide) x 6.4" (high), 12.1" diagonal full color touchscreen WXGA display with 1280 x 800 pixels. It has an automatic backlight sensor that adjusts the screen brightness to the ambient light. You can also manually adjust the brightness by pressing the power key repeatedly to scroll through the brightness levels. You can also choose between day and night color schemes. The large screen lets you create combination pages of two, three, or four functions on the screen at once.

Keypad: In addition to touchscreen controls, the ECHOMAP Ultra 2 126sv 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 Ultra 2 126sv has a built-in multi-band GPS receiver and internal antenna that collects data from overhead satellites to establish your current location. In addition to the U.S.-based GPS system, the unit can utilize GLONASS, Galileo, and Beidou international positioning systems for improved location accuracy. The GPS signal strength is indicated on the top of the screen in a bar graph (5 bars maximum). You should make sure the device has a clear view of the sky so the antenna can receive the GPS signal. The device is equipped with a 10Hz GPS receiver which refreshes its position and heading 10 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 Navionics+ inland and coastal maps of the U.S. and Coastal Canada with depth range shading, up to 1' contours, and shallow water shading. For the United States, the maps provide detailed coverage of the entire U.S. coasts, lakes, rivers, and inland waterways, including Alaska and Hawaii. Canada coverage includes coastal British Columbia, the Great Lakes, St. Lawrence Seaway, New Brunswick, and Nova Scotia. Coverage also includes Bermuda, the Bahamas, Baja California, the Gulf of California, Johnson Atoll, and Palmyra Atoll/Kingman Reef. The included 1-year subscription lets you download updates daily via the ActiveCaptain app. After one year, you can renew the subscription for up to 50% less than the cost of a new chart. Additional maps are available on microSD or you can download them to your own microSD card and insert them into the device. ECHOMAP Ultra 2 126sv supports optional Garmin Navionics Vision+ premium cartography with high-resolution relief shading, satellite imagery, sonar imagery, and more.

Auto Guidance+: The built-in Auto Guidance+ technology is a combination of the best of Garmin and Navionics automatic routing features. Auto Guidance+ gives you a suggested dock-to-dock path to follow through channels, inlets, marina entrances, and more. Auto Guidance+ is for planning purposes only, and does not replace safe navigation operations.

Quickdraw Contours: The ECHOMAP Ultra 2 126sv 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 with 1' contours based on the sonar results from an attached compatible transducer. Compatible transducers include Garmin ClearVü/SideVü, 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. If you desire, you can share your maps with the Garmin Quickdraw Community on the Garmin Connect app.

Mounting Options: The 126sv 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.

NMEA 2000 / NMEA 0183: The ECHOMAP Ultra 2 126sv 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. The unit also supports the NMEA 0183 standard, which is used to connect various NMEA 0183 devices, including VHF radios and instruments, autopilots, wind and heading sensors.

Wi-Fi Enabled: The 126sv lets you wirelessly share information, including sonar, waypoints, and routes, with other ECHOMAP Ultra 2 or UHD2 chartplotters that are on your boat. It can also connect to a mobile devices using the ActiveCaptain app.

ActiveCaptain App: The free Garmin ActiveCaptain app on your mobile device provides a connection to the ECHOMAP via Wi-Fi. 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 10.0 and up, or Apple iOS 15.0 or later.

Fishfinder Features

CHIRP Sonar: The ECHOMAP Ultra 2 126sv is equipped with the 500-watt Garmin GT56UHD-TM Ultra High-Definition scanning sonar transducer. This single transducer provides the highest resolution ClearVü and SideVü scanning sonar images with remarkably clear target separation and definition. You'll be able to view incredibly detailed images of fish and structure up to 800' below your boat (in fresh water with CHIRP sonar). With three SideVü sonar frequency settings (455kHz, 800kHz, and 1000kHz), you'll have options for extended range views out to 500' to each side. 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. In addition to sonar, the transducer also measures water depth and temperature. The GT56UHD-TM comes with an attached 25-foot cable which is terminated with a 12-pin connector.

Note: The transducer comes with both transom and trolling motor mounts.

Sonar Views: The ECHOMAP Ultra 2 126sv'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, ClearVü, or SideVü 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.

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 CHIRP High-Wide: 150-240 kHz
    • Ultra High-definition ClearVü/SideVü: 455 kHz (425-485 kHz), 800 kHz (790-850 kHz), 1000 kHz (940-1100 kHz)
  • Transmit Power Output: Traditional CHIRP 350W (RMS); ClearVü/SideVü 500W
  • Maximum Depth:
    • Traditional CHIRP: 800 feet (freshwater)
    • ClearVü: 400 feet
    • SideVü: 500 feet
Chartplotting Features

Chart Views: The ECHOMAP Ultra 2 126sv has coastal and inland maps pre-loaded into its memory for the U.S. and Coastal Canada. Other maps and 3D views are available with optional premium charts (sold separately). 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. Available with premium charts in some areas.
  • Mariner's Eye 3D: The Mariner's Eye 3D view provides a more detailed, 3-dimensional view from above and behind the boat to provide a visual navigation aid. This is particularly helpful for navigating tricky shoals, reefs, bridges, and channels.
  • Fish Eye 3D: 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.
  • Relief Shading: The Relief Shading chart provides high-resolution elevation shading of lakes and coastal waters, helpful for fishing and diving.

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.
