Sonar and transducer

The Garmin ECHOMAP UHD 75sv offers access to three sonar technologies with the included transducer, these being standard CHIRP sonar, ClearVü, and SideVü. It also has a Panoptix Ethernet port, though, and can be paired with one of the available Panoptix live transducers.

The unit supports multiple sonar frequencies, including 50/77/200 kHz for standard CHIRP, and 260/455/800/1000 kHz for the structure scanning sonar SideVü & ClearVü.

As we’ve mentioned above, the unit includes the new GT56UHD transducer which supports 1000 kHz, as opposed to the older GT54UHD model. This transducer features 25 ft. (7.6 m) of cable with a 12-pin connector and integrates a temperature sensor. It comes with a transom mount.

For the ClearVü and SideVü sonar modes, the transducer uses thin and oval beams and supports three different CHIRP frequency channels. The beamwidths are 1.1° x 52° @ 455 kHz (425-485 kHz), 0.64° x 35° @ 800 kHz (790-850 kHz), and 0.52° x 52° @ 1000 kHz (940-1100 kHz). The maximum depth capability of the ClearVü sonar is 400 ft. (122 m), while the maximum side range of the SideVü beams is 500 ft. (152 m).

Although the unit supports multiple frequencies for the 2D CHIRP sonar, the included transducer can only use the High CHIRP mode in a frequency range of 150-240 kHz. It uses a conical beam with a coverage of 24°-16° and a maximum depth range of 800 ft. (244 m).

Needless to say, the unit offers the full range of standard sonar applications, including Fish Symbols ID, A-Scope, Bottom Lock, various alarms, Circular Flasher for ice fishing, Sonar Recording, and more. Also, since it’s one of the ECHOMAP UHD units released in 2020, it has the vivid color palette for the SideVü and ClearVü sonar.

Navigation features

The Garmin ECHOMAP UHD 75sv 010-02521-00 is equipped with the Canada LakeVü g3 charts. These cover more than 13,500 lakes of which more than 4,800 have 1-foot contour detail. They offer features such as Auto Guidance for route planning, Depth Range Shading, and Shallow Water Shading. They are also enhanced with Navionics content and offer considerably more data than the older LakeVü charts.

Of course, the unit supports other charts as well. The list includes the LakeVü g3 charts for the U.S., LakeVü g3 Ultra, BlueChart g3, and BlueChart g3 Vision. It’s important to mention that even though all these charts are enhanced with Navionics data, the unit itself cannot use Navionics+ or Navionics Platinum+ charts.

The unit has its own bathymetric mapping application – the Quickdraw Contours function. It can use the 2D sonar data and the GPS data to reveal and record the depth contours of the lake that you’re scanning. Thus, you can create your own custom fishing maps. You can also share them with the Garmin Quickdraw Community or download charts already made with this tool from the database.

The unit’s internal GPS operates a 5 Hz; this essentially means that it can offer position updates 5 times per second. It has a GPS speed function and can work with the WAAS, EGNOS, and MSAS satellite systems for position augmentation. It also has waypoint creation, route creation, and track recording functions. Plus, you can pre-plan a fishing trip with the ActiveCaptain app.

The SailAssist page is also available with this Garmin unit. The sail assist features include laylines, enhanced wind rose, heading and course-over-ground lines, time to burn before the start, and the race times. The unit supports AIS data, DSC data, and is ActiveCaptain compatible. You can also compatible with Force Trolling Motors, heading sensors such as SteadyCast, and more. It does not support Radar, though.

Control unit features

This Garmin fish finder and chartplotter features a 7-inch WVGA display with LED backlight for improved readability at night and in direct sunlight and a pixel resolution of 800H x 400V. It is also IPX7 waterproof.

The unit’s interface is very easy to use. It combines touchscreen technology with keypad technology. You can customize its homepage with the application combos that you use the most for quick access. It also provides split-screen possibilities for up to four applications per view. For example, you can view the 2D sonar, the CV sonar, your maps, and another application of your choice at the same time.

The unit has an NMEA 2000 connector and also supports NMEA 0183. Thus, you can easily connect it to an already existing boat network so it can communicate with other boating instruments. It is AIS and DSC compatible but does not support Radar. It also has an Ethernet port but that is only for Panoptix transducers. Plus, it features a microSD card slot which you can load with a different chart card, or with a blank card for data backup. It accepts data cards up to 32 GB.

The unit also has WiFi connectivity and is compatible with the ActiveCaptain app. This being said, you can install this app on your smartphone in order to sync it with your ECHOMAP UHD chartplotter for data transfer, pre-planning a fishing trip, software updates, and even for receiving smart notifications from your phone on the display of the chartplotter.

Last but not least, the unit comes with the standard tilt-mount with quick-release. A flush mount and a protective cover are also included.
