garmin echomap 73sv hd review

If you’re looking for a high-end fish finder that is packed full of features, the garmin echomap 73sv hd might be just the thing you need. It offers a wealth of functionality, including smartphone connectivity and advanced sonar technology.

The 73sv is a powerful sonar system that allows you to see up to a third of the way down to bedrock, which makes it perfect for kayak anglers who want a more accurate read on their fishing. It also features a variety of frequencies that allow it to operate in all kinds of water, from shallow lakes to deep oceans.

You can also use it to create custom topographic maps of the bottom in real time, which is perfect for inland lakes or remote areas that don’t have Navionics mapping. Those features, along with an IPX-7 waterproof rating and lots of other advanced features, make the 73sv the best fish finder for serious anglers who want to improve their catch rate and enjoy better boating experiences.


The echomap 73sv has built-in CHIRP (Compressed High-Intensity Radiated Pulse) sonar capabilities, which transmit a continuous sweep of frequencies on a low-to-high range for more detailed returns than traditional sonar. This is a great feature for fisherman who like to get a close look at their targets, but it’s not the best choice for complex mapping.

LakeVu HD cartography

The 73sv is loaded with the best preloaded LakeVu HD maps available, which include over 17,000 lakes and rivers in the U.S. These maps show underwater features in incredible detail, including one-foot contour markings that go from shoreline to shoreline as you fish.
