Garmin Echomap UHD 73cv Review 2023

The Garmin echomap uhd 73cv is a well-known fish finder with a lot of great features. It has high-quality sonar and it’s easy to use. You can download the app to your phone and turn the high-definition screen into an external monitor for your laptop or tablet. We are going to discuss the Garmin Echomap UHD 73cv review. The Echomap UHD 73cv has everything you need to enjoy your time out on the water – touchscreen display, 200 Watts RMS power output, dual-channel CHIRP sonar imaging technology, and compatibility with all the Garmins and accessories you could ever want.

The display is large and easy to read, which makes this model ideal for anglers who want an accurate picture of what’s happening around them when they’re out fishing.

The range on this unit is impressive as well—you’ll be able to see everything from nearby boats out into open ocean waters thanks to its high-speed transducer (1/32nd scale). While some people may find that having such a wide field of view can cause navigation issues at times due to over-scanning issues with their maps/terrain layers being displayed behind them while they try navigating through difficult terrain features like steep slopes or deep valleys; most users find these things relatively easy going because they don’t have any problem recognizing where their current location is relative versus where other landmarks are located around them on land so long as there aren’t any obstructions between those two points.”

Things to Consider Before Buying Garmin echomap uhd 73cv

CHIRP Sonar Technology

The CHIRP sonar technology uses a single-beam transducer to detect fish and prey, with dual-beam transducers for bottom-fishing. The unit has a range of 15 feet in open water, which can be extended up to 100 feet by adding an optional sonar repeater unit.

This display is the same resolution as most smartphones and tablets today. With its high-resolution sonar and advanced mapping features, you can easily find fish in shallow water or at depths up to 600 feet (180 meters). You’ll never miss another target again with this unit’s bright colors and clear visuals! It has an LCD screen, which displays images in a 16:9 aspect ratio, making it easier for you to see more detail than some other fish finders that have smaller screens with square designs.

The Garmin echomap uhd 73cv fish finder also features shatter-resistant glass that protects against drops from up to 3 feet high onto hard surfaces like concrete or asphalt parking lots when using this device outdoors without any cases around it (unless you want one).

The most important facet of your fish finder is the transducer. It’s what sends out sound waves, and it receives them back. There are many different types of transducers, including Ultrasonic, InfraRed (IR), Magnetic and Optical.

The best way to understand how they work is by looking at an example:


The Garmin echomap 73cv comes with a variety of networking options, including:

  • Optional Bluetooth and Wi-Fi connectivity.
  • NMEA 2000 (or 0183) connectivity for compatibility with marine electronics.

You can also connect to your smartphone via a USB Port if you don’t want to use the included Bluetooth feature, but this isn’t an option for anyone who wants to use their device in freshwater or saltwater environments where wireless communication doesn’t work well at all times of day, so it’s not recommended unless necessary.
