Garmin ECHOMAP UHD 74sv - Review

Garmin ECHOMAP UHD 74sv – Review



Should I upgrade to a – Garmin ECHOMAP UHD 74sv?

Let’s take a detailed look at the specs, look at a couple of thoughts from some who already have, and compare the UHD to the Plus and Ultra.



The Garmin ECHOMAP UHD 74sv – Is an easy-to-use, easy-to-setup 7″ color chartplotter/sonar combo with a keyed-assist touchscreen targeted towards the inshore and inland fisherman.

It has incredibly clear CHIRP traditional sonar, CHIRP ClearVü/SideVü scanning sonar, and includes built-in support for both Garmin’s super-clear Ultra High-Definition scanning sonar and Panoptix LiveScope.

Creating custom fishing maps on-screen with 1’ contours is quick and easy with built-in Garmin Quickdraw™ Contours mapping.

The ECHOMAP UHD 74sv comes already preloaded with BlueChart g3 charts with integrated Navionics data for the coastal U.S plus built-in Wi-Fi® to pair with the free ActiveCaptain app for updates and chart upgrades.



Garmin ECHOMAP UHD Series Features

Garmin ECHOMAP UHD Series Features


ECHOMAP UHD Series – Comes in 3 screen sizes, features Ultra High-Definition scanning sonar capabilities, is preloaded with Garmin BlueChart g3 or LakeVü charts, and has built-in Wi-Fi® for access to the Garmin Active Captain marine app for updates and chart upgrades.

The 7″ & 9″ units support UHD SideVü, Panoptix LiveScope, and Garmin’s new Force trolling motor.



Clear Screen and Sunlight Friendly – This is one of the first things you will pick up on with the ECHOMAP UHD 74sv. The screen is pretty bright and has a good viewing angle even in direct sun.

Keyed assist touchscreen – The 7″ screen uses touchscreen navigation along with a keypad with 4 quick access shortcut keys to assign the active screen when held. The Shortcut button opens the assigned screen when pressed.

Built-in GPS – The 5hz GPS receiver acquires satellites quickly on startup and shows exact location pretty quick.

Network Capabilities  – Easily share sonar data, waypoints, routes, and supplemental charts with other 7″ or 9″ ECHOMAP UHD or ECHOMAP Ultra units.

NMEA 2000 | 0183  – Connect the UHD to an autopilot, digital switching, weather, FUSION-Link audio system, media, VHF, AIS from one screen.


Garmin ECHOMAP UHD 74sv - Screen Control

ECHOMAP UHD 74sv | Screen Control


TouchScreen navigation menu – Setting up the ECHOMAP UHD 74sv for how you fish or cruise is simple and adding custom screens and settings is pretty straightforward without having to do a deep dive into the manual.

You can add items, rearrange items on the home screen, and even change to the background image.


Garmin ECHOMAP UHD 74sv Menu



Custom Pages – Creating custom combinations is easy.  Set up a custom screen for fishing with sonar split screen with traditional on one side and clearvu on the other.

Set one up with chart and sonar for cruising or one for finding structure using ClearVü and SideVü sonar only. Then assign up to 4 custom screens to the shortcut keys for quick access.

Complete Garmin Sonar Support


Built-in sonar capabilities – Includes a 500W CHIRP traditional sonar, ClearVü/SideVü scanning sonars, Ultra High-Definition scanning sonar and supports the full line of Panoptix all-seeing sonar transducers, including the Panoptix LiveScope system.

Additional info on the Panoptix™ all-seeing sonar line.

TRADITIONAL CHIRP SONAR –  Instead of sending just 1 single frequency at a time, CHIRP sonar sends a continuous sweep of frequencies ranging from low to high.


Garmin ECHOMAP UHD 74sv - Traditional Chirp Sonar

ECHOMAP UHD 74sv | Traditional Chirp Sonar


ECHOMAP UHD 74sv - Traditional Chirp Sonar Target Separation

ECHOMAP UHD 74sv | Traditional Chirp Sonar Target Separation


The 500W CHIRP sonar sweeps a continuous range of frequencies, from low to high, in a single transmission. The returns from each frequency in that transmission are then interpreted and showed on the screen.

Since this continuous sweep of frequencies provides a much wider range of information, CHIRP sonar can create a very clear, high-resolution image.

As you can see above, you get far greater target separation and more defined arches than you would with standard 50/200 kHz sonar. The maximum working depth is about 2,300 ft @ 77kHz, freshwater, and 1,100 ft @ 77kHz, saltwater depending on the bottom type and water conditions.


Garmin ECHOMAP UHD 74sv - Sonar Recording

ECHOMAP UHD 74sv | Sonar Recording


Recording the Sonar Display – Very cool feature that allows you to record the sonar screen for playback on Garmin HomePort™ and review it later. I find it pretty valuable to be able to look over the recording from the day and mark any spots that I what to check out in more detail.

As I play it back, I can stop and drop a GPS mark on something interesting and upload it to the GPS to take a look at the next time I’m on the water. See the image above.

To Start Recording – Insert a memory card into the card slot. From a sonar view, select MENU > Record Sonar. Garmin says 15 minutes of sonar recording uses approximately 200 MB of space of the inserted memory card but I recorded several hours and only had a 980Mb file.

An individual recording automatically ends after it reaches 4 GB in size. You can record sonar data until the card reaches capacity.

Note: Before you can playback the sonar recordings, you must download and install the Garmin HomePort™ application and record sonar data onto a memory card.

Sonar History Rewind –  As the ECHOMAP UHD 74sv gets sonar data, while you’re tracking bottom or fish, you can go back and see what you previously went over by just tapping the screen and scrolling back. The amount of sonar history available to scroll back and the view is about from 2-3 screens wide.

The scroll speed will affect how you will have recorded. For example, if the GPS is set to a slower scroll speed in the sonar menu, the window of time the unit can rewind will be greater.  If the device is set to its fastest scroll speed, you will see a smaller window of time within the sonar rewind.

If you see something good that you just marked, rewind the history, tap the screen and drop a waypoint on it to save it. The best honey holes are often found when moving from one location to another.



ClearVü SONAR – ClearVü sonar is mainly used to identify the structure and gives you a nearly photographic image structure below the boat.

With ClearVü, you see structure, submerged objects, and fish separation more clearly.

Garmin ECHOMAP UHD 74sv - Traditional CHIRP vs Clearvu

ECHOMAP UHD 74sv | Traditional CHIRP vs ClearVü


Instead of a cone-shaped beam like the traditional CHIRP sonar, ClearVü scanning sonar sweeps a narrow beam of very high-frequency (455 or 800kHz) from side to side, producing “slices” that are combined to create very detailed images.

Fish are easily identifiable on Traditional View with CHIRP whereas Structures are well defined using ClearVü.

For fishermen and divers looking for a structure like wrecks, reefs, log piles and other underwater natural and man-made features, ClearVü is a great tool.


Garmin ECHOMAP UHD 74sv - CHIRP ClearVu Sonar

ECHOMAP UHD 74sv | CHIRP ClearVü Sonar



SideVü SONAR  –  SideVü  is a high-frequency sonar that gives a true-to-life view of structures and targets on either side of the boat. Like ClearVü, SideVü scanning sonar sweeps a narrow beam of very high-frequency (455 or 800kHz) out to the side, producing “slices” that create very detailed images.

You see a crystal clear image that makes it easy to identify wrecks, structures, rocks, and even fish that are stacked up next to or above them.

The distance you can scan out to the side depends on the depth but can be usable out several hundred feet which is excellent for covering and searching lots of areas quickly.

Garmin ECHOMAP UHD 74sv - Clearvu vs Ultra High-Definition Scanning Sonar

ECHOMAP UHD 74sv | ClearVü vs Ultra High-Definition Scanning Sonar


Ultra High-Definition ClearVü – Transmits brilliant image clarity of structure and fish below the boat at greater depths than other high-frequency scanning sonars by utilizing a downward-facing element to put more power on targets.

Note: A  UHD Transducer is required for Ultra High-Definition Sonar. Some bundles include the GT54UHD-TM transducer.


ECHOMAP UHD 74sv - Ultra High Definition Sonar

ECHOMAP UHD 74sv | Ultra High Definition Sonar


Ultra High-Definition SideVü –  Stunningly clear images of structure and fish out to the sides of the boat. This makes searching new areas easier and faster because you can see everything the first time with excellent detail.


ECHOMAP UHD 74sv - Ultra High-Definition Sidevu Scanning Sonar

ECHOMAP UHD 74sv | Ultra High-Definition SideVü Scanning Sonar


Ultra High-Definition scanning sonar gives you some additional depth performance. It shows very detailed images of fish and structures up to 200’ below the boat with 800 kHz ClearVü, while two SideVü sonar frequency settings (455/1200 kHz) provide a depth range of up to 125’.





Panoptix Sonar –  is pretty amazing sonar technology. It gives us the ability to see all around the boat in real-time and in 3 dimensions.

Panoptix shows highly detailed, easy-to-interpret live scanning sonar images of structure, bait, and fish swimming below and around your boat in real-time, even when the boat is stationary.

Images are so clear, that Garmin says with a little practice, we might be able to identify species!

Both LiveScope Forward and LiveScope Down modes are included in one transducer and are available with either transom or trolling motor mounts.  To use Panoptix sonar, you need a compatible chartplotter which the ECHOMAP UHD 74sv is and a compatible transducer. The transducer plugs right into the Panoptix network port.


ECHOMAP UHD - Panoptix Livescope Forward

Garmin ECHOMAP UHD | Panoptix Livescope Forward


Panoptix Livescope Forward is a cool tool for scouting and fishing out ahead of the boat. You get live, detailed images of structure and fish out to about 200′ – even while the boat is sitting in one spot.  A live sonar looks at fish moving toward or away from the boat.



ECHOMAP UHD - Panoptix Livescope Down

Garmin ECHOMAP UHD | Panoptix Livescope Down


Panoptix LiveScope Down gives us live scanning sonar images of structure and swimming fish in awesome detail below the boat up to 200′ out from the transducer. Shows real-time moving sonar images of baitfish and large fish swimming below the boat and pinpoints distance left or right and their depths



Charts and Mapping


Preloaded Charts & Maps –  The UHD 74sv comes with the latest BlueChart g3 cartography and integrated Navionics data for very detailed charts and mapping.

BlueChart g3 Charts cover the coastal U.S., including the East and West coasts, Gulf of Mexico, and the U.S. and Canadian sides of the Great Lakes.

Upgrading charts to BlueChart® g3 Vision is easy with the microSD card slot located on the front of the device and the Active Captain App.


ECHOMAP UHD 74sv - Chart Auto Guidance

ECHOMAP UHD 74sv | Chart Auto Guidance


Garmin Auto Guidance technology –  shows a suggested route to a destination, based on specs that you enter in the device like draft, and vertical height restrictions.


ECHOMAP UHD 74sv - BlueChart g3 - Depth Range Shading

ECHOMAP UHD 74sv | BlueChart g3 – Depth Range Shading


Depth Range Shading – is shown in high-resolution for up to 10 depth ranges, so you can see your needed depth at a glance by color.


ECHOMAP UHD 74sv - BlueChart g3 Shallow Water Shading

ECHOMAP UHD 74sv | BlueChart g3 Shallow Water Shading


Shallow water shading –  allows for shading at a user-defined depth to give a clear picture of shallow waters to avoid based on your own draft.

Detailed Contours  –  1′ contours that provide a more accurate look of bottom structure for improved fishing charts and enhanced detail in swamps, canals, and port layouts.



Garmin Quickdraw Contours


Quickdraw Contours instantly creates personalized HD maps with 1’ contours and depth labels for any body of water as you fish.

When Quickdraw Contours records data, a colored circle surrounds the vessel icon. This circle represents the approximate area of the map that is scanned by each pass.  Quickly see where you have been.

The screen shows maps being created instantly in real-time. Easily add labels, mark timber, brush piles, favorite fishing spots, and anything you want to remember on your map for the next trip.

Improve Your Saltwater Maps & Uncover unknown areas – Many areas have no map detail. With Quickdraw, you can create maps that show you depth contours clearly labeled on the screen. You also can improve your existing maps that show locations of underwater mountains, drop-offs, crevices, or wrecks.


ECHOMAP UHD 74sv - Quickdraw Contours

ECHOMAP UHD 74sv | Quickdraw Contours


The maps yours – customize them to fit your needs. Keep the maps for yourself, or share them with others in the QuickDraw Community on Garmin Connect.

You can view Garmin Quickdraw Contours on a combination screen or as a single view on the map. The amount of saved data depends on the size of your memory card, your sonar source, and the speed of your boat as you record data.

You can record longer when you use a single-beam sonar. It is estimated that you might be able to record about 1,500 hours of data onto a 2 GB memory card.

When you record data on a memory card in your chartplotter, the new data is added to your existing Garmin Quickdraw Contours map and is saved on the memory card. When you insert a new memory card, the existing data does not transfer onto the new card.



Active Captain 


Connected Boating App –  The free Active Captain app from Garmin gives the ECHOMAP UHD a connection for upgrading charts, maps and access the Garmin community.

Wherever you are, you can have unlimited access to your cartography, purchase new maps and charts, and access the Garmin Quickdraw™ Contours Community. Active Captain is available for both iPhone and Android.
