Features

Overview: The Garmin ECHOMAP™ UHD2 73cv (Garmin part # 010-02594-01) is a combination chartplotter and fishfinder. It comes preloaded with Garmin's exclusive U.S. LakeVü g3 inland map charts 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 UHD2 73cv has a 7" (diagonal) full color touchscreen display that can be mounted in a variety of ways. The fishfinder has a 500-watt (RMS), Ultra High-Definition 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 UHD2 73cv has a 6.1" (wide) x 3.4" (high), 7.0" diagonal full color touchscreen 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. With the large display, you can create custom combination pages with up to three different functions on the display at once.

Keypad: In addition to touchscreen controls, the ECHOMAP UHD2 73cv 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 arrow buttons for scrolling around the map and highlighting menu options that can be selected by the Select button. The Back button returns to the previous screen. The Mark button can save the present location as a waypoint, or to mark a MOB (Man Overboard) location when held.

Global Positioning System: The ECHOMAP UHD2 73cv has a built-in GPS receiver and internal antenna 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 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 via download.

Quickdraw Contours: The ECHOMAP UHD2 73cv 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, SideVü, DownVü, or NMEA 2000-compatible transducers. If you are using more than one transducer, you can choose which sonar device gives you the best results.

Mounting Options: The 73cv consists of a display/control unit and a tilting 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.

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 8.0 and up, or Apple iOS 13.0 or later.

Fishfinder Features

CHIRP Sonar: The ECHOMAP UHD2 73cv is equipped with the 500-watt Garmin GT20-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 up to 1900' (traditional) and 750' (ClearVü) below your boat. 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 GT20-TM comes with an attached 20-foot cable which is terminated with a 4-pin connector.

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

Sonar Views: The ECHOMAP UHD2 73cv'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. In this view, you can separately adjust the gain for each frequency.

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).

Chartplotting Features

Chart Views: The ECHOMAP UHD2 73cv has 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, 3D Chart, Fish Eye 3D, and Relief Shading.

Pages: The chartplotter lets you view sonar views in full screen, or multiple views in combination screens. You can create a custom combination page with two or three sonar views with several layouts to choose from. You can also customize the data in the data overlays on a screen, showing your GPS position (Latitude/longitude), GPS speed, GPS heading, water temperature, water depth, and time of day.

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 UHD2 73cv lets you view data on tides, currents, and celestial conditions for a specific 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.
