Garmin Echomap Uhd 73sv Review 2023

The Garmin Echomap UHD 73sv is the best sonar fish finder that can help you find fish and other aquatic life in shallow waters. On This Garmin Echomap Uhd 73sv Review, we talked about features and it’s easy to use, but there are some minor issues with this unit that keep us from giving it a total five-star rating.

The Garmin Echomap 73SV is one of the best sonar fish finders on the market. It has a large screen, which makes it easy to see the depth and fish targets. The display is clear, bright, and easy to read even in direct sunlight. You can also adjust the brightness of your screen if you want to reduce glare when using your device outdoors or at night (or both).

Key Features

  • High-resolution display: The Garmin Echomap UHD 73sv has a large, high-resolution screen. It’s easy to read from any angle and the 1-inch diagonal makes it easy to view at night or in bright sunlight.
  • SideVu and clearVu scanning sonar: The Echomap UHD 73sv comes with two different types of sonar—SideVu (which uses a downward pointing sonar) and ClearVu (which uses a forward-looking sonar). Both work well together, giving you everything you need for accurate fish finder hunting.
  • Auto guidance: The Garmin Echomap UHD 73sv offers automatic positioning on your boat so that you don’t have to worry about getting lost while fishing!


Garmin has a long history of making top-of-the-line GPS units, and the 73sv is no exception. The unit includes all the features you’d expect from this kind of device: it can connect to your smartphone or tablet via Bluetooth and display maps on its screen as well as provide turn-by-turn directions along with spoken prompts. It also comes equipped with ClearVu sonar scanning sonar that shows you exactly where fish are schooled up in the water around you (your boat too).

It also comes with Auto Guidance Plus, which automatically guides boats through narrow channels by measuring depth with SideVu sonar and displaying information about shoaling rocks on screen so users know how close they are getting before driving over them! And finally, there’s Panoptix LiveScope which gives users access to real-time data like tidal currents, water clarity levels… basically, everything needed for safe navigation around reefs at low tide times

  • The display is bright and clear.
  • The screen is large, easy to read, and has a good contrast ratio.
  • Easy to use.
  • Most menus are intuitive, so you won’t have trouble navigating them even if you’re new to echomap units.
  • It’s easy to install—and even easier when paired with an external antenna mount (sold separately).
  • The unit is waterproof and floats, so you don’t have to worry about it getting wet or sinking if it gets knocked off your boat.
  • It can be used as a handheld device, which is great for scanning lakes and rivers.
  • Expensive.

Things to Consider Before choosing Garmin Echomap Uhd 73sv Fish Finder

The size of the screen is pretty small compared to other models on the market today (such as our favorite portable GPS unit, TomTom Go 930). We think this could be an issue if you want something portable but still want all of its features including maps, audio cues, and traffic updates—which means you’ll need to rely on downloaded content like podcasts or audiobooks instead of live traffic reports to get those details when necessary.* There isn’t any built-in GPS functionality so if someone else is using your phone while running trails through forests then they might not always know where exactly they’re going!

First Impressions

The first thing I noticed was how light it was. It’s so much lighter than other models I’ve used in the past, and it makes a big difference when you have to carry it around all day long.

The screen is also really nice. It has an anti-glare coating on top of it, which means you can see from any angle without having to squint or strain your eyes. This feature alone makes this model worth investing in over other options out there because most people prefer to use their GPS devices during hiking or biking trips rather than when driving around town (and if they do drive, then they would rather use one that doesn’t require them looking through tiny little windows).

The Packaging

The Garmin Echomap Uhd 73sv is a lightweight device that can be easily carried in a pocket, backpack, or briefcase. It fits well into your hand and weighs less than 7 ounces (or 200 grams). The packaging for this product is made of cardboard with white panels on both sides that fold out when you open the box.

The box includes everything you need to get started:

  • A user manual printed on 6 pages (in English) with clear instructions on how to use your new navigator;
  • An AC adapter;
  • A USB cable;
  • 3 AAA batteries included;

On its page inside this guidebook are three sections: Introduction / Specifications & Features / Additional Resources

The Build

The Garmin Echomap Uhd 73sv’s build is excellent. The screen is large and easy to read, the mount is easy to install, and the buttons are easy to use. The body of the unit itself feels sturdy enough that you can trust it in your bag or pocket without worrying about it breaking (although I’d still be careful with throwing it around). It’s also waterproof up to 1 meter for 30 minutes so this might come in handy if you’re hiking through some wet areas!


The display is a 7-inch display with a resolution of 800 x 480. It’s sunlight readable, and it has a touchscreen. The high-definition screen makes it easy to read and navigate the map, especially in high-traffic areas where the GPS signal can be spotty or non-existent.

The screen is also easy to read in direct sunlight, which makes it a great option for outdoor activities. The touch screen is responsive, making it easy to use even with gloves on. The screen is also durable. It has a scratch-resistant coating, which means it can withstand harsh environments without being damaged. The device is water resistant up to a depth of 1 meter for 30 minutes; however, it’s not waterproof and should not be used while swimming or diving.

CHIRP Sonar is a high-definition sonar technology that uses sound frequencies to create an image of the seafloor. It’s better than traditional sonar, and it’s more expensive, but it offers many advantages when used for fishing or other purposes.

CHIRP sonars are designed to give you an accurate picture of your surroundings without having to go into dangerous waters (or even just scuba diving). You can see things that are in your way, such as wrecks and rocks, which can help keep you out of trouble if any dangers are lurking beneath the surface!

Navigation and Maps

The maps are available for the US and Canada, but you can download maps for other countries. They’re detailed and accurate, so you’ll have no trouble using them to mark waypoints or routes. You can use the maps to find fish, baitfish, and structures as well as points of interest like beaches or harbors.

SideVü and ClearVü

SideVü and ClearVu are two different technologies that work together to give you a more detailed view of what’s going on around your boat. SideVu is a wide-angle camera, while ClearVu is a high-resolution camera that can provide extra details about the area around your boat.

Both systems have their advantages: for example, if you’re on an open water adventure in the middle of nowhere and want to know what’s lurking behind rocks or sandbars, then SideVu will help you see them as clearly as possible. If objects are floating around in front of your boat (like dolphins), then ClearVu will be able to record them while they swim past.

The Best Features

The Garmin Echomap Uhd 73sv is a great choice for sailors who want to get the most out of their navigation experience. It has everything you need to track your boat and guide yourself safely through the waters.

The device comes with a GPS connection, waypoints, and trackback functionality so that you can store information about where you’ve been or where you’re going before having to manually input it into the unit itself. You can also use clearvu (the unit’s sonar) to scan objects around you while on deck without having them obstruct your view—this will help keep hazards at bay when docking or leaving port without damaging their surroundings!

Another handy feature is sidevu scanning sonar which allows users to make sure there aren’t any rocks underfoot before proceeding down below deck; this could save lives if someone slips while trying not only to get off quickly but also avoid injury from hitting something sharp along with falling onto hard surfaces below deck due again–

Screen Size and Resolution

The Garmin Echomap Uhd 73sv’s screen size is 7 inches and its resolution is 1024×600, which puts it in the middle of the pack among its class. This is not a bad thing, as you’ll be able to see your course even when using this unit on a sunny day.

The high-definition display offers crisp images that are clear and easy to read at all times. Both ClearVu and SideVu scanning sonar provide great detail about objects in front of the boat, making them ideal for shallow-water fishing or trolling through calm waters near shorelines with less visibility than deep ocean areas.

GPS Connection, Waypoints, and Trackback

The GPS connection is a new feature on the 73sv. It’s an optional feature, not required for you to use your device, but it does help when you are outdoors and want to get specific directions or locate where you are on a map. You can set up waypoints in advance so that when you want them, they will appear as blue dots on the screen of your unit. The waypoint list also allows users to create new locations by entering coordinates into their GPS unit or computer software like Google Maps or ArcGis Desktop (free). This comes in handy if someone else wants directions from somewhere else than where they are currently located—for example at home!

ClearVu And SideVu Scanning Sonar

The ClearVu and SideVu scanning sonar feature is one of the most useful in this unit. It allows you to see a wide swath of the water column, or a narrow swath if you prefer. This is especially useful for finding fish in shallow water or around docks and boat lifts. With these two features, it’s easy to pinpoint any object underwater within your sonar field of view.

The ClearVu sonar scans an area from 10 meters down to 200 meters, while the SideVu scans from 1 meter down up to 30 meters (or even more). Both units have a maximum range limit of 600 feet/200 meters when using 2 kHz frequencies as they don’t work well with higher frequencies due

Purpose-Built Auto Guidance and Coastal Routing with Panoptix LiveScope

Panoptix LiveScope is a feature that displays the sonar image in real-time. It shows the fish, structure, and baitfish on the screen. You can see what is under your boat, which makes it easier for you to find fish and structures. The Echomap Uhd 73sv comes with this feature as well as a few other great features like Lowrance’s Fathom 3D mapping technology (which allows you to see underwater terrain), Garmin’s RadarChart 360° dual-beam radar with mounted transducers, along with an HD camera system that takes high-definition video of your boat while also recording audio commentary from observers aboard your vessel.

If you’re looking for an affordable way to get started fishing without breaking the bank, this might be just what you need!
