Garmin Echo 551dv


Garmin and Humminbird have been fighting for market supremacy for many years now, but it all comes down to the features of the products they’ve been developing. For example, this is a somewhat larger fish finder that features a color display and a resolution of 480 by 640.

It’s pretty obvious that technically, the quality of the displayed images should be greater with the Garmin Echo 551dv, compared to the ones of the previously mentioned Humminbird.

The unit has a frequency of 77/200 and is capable of getting pictures of anything from shallow waters down to 2,300 feet in depth. The transducer is included in the pack, which is easy to install both according to the official product description and according to what customers are saying.

The Garmin Echo 551dv is backed by a 1-year warranty.

Many people who have chosen this product were so satisfied with what they got that they wrote positive Amazon reviews. Some buyers state that they went for this variety even though they were initially considering Lowrance and Humminbird.

Buying guide


What are the best fish finders for sale? If you’ve been looking for an affordable, convenient yet fully functional fish finder, you’ve come to the right place. We like giving prospective buyers a helping hand, so we’ve put together a short yet informative buying guide, to help you correlate your needs with the features you might want in a unit.



Screen size and resolution

Although manufacturing brands like to claim otherwise, the size of the display matters a great deal. Modern alternatives do a pretty good job at providing accurate images, unlike their older counterparts, of which the screens resembled the ones of ancient mobile phones. The resolution also has a say when it comes to image quality, so pick as high one as possible.


Color vs black and white

With black and white fish finders, it’s pretty difficult to understand just what you’re looking at. If, however, you’re well-versed in the art of using these devices, you might find little to no trouble distinguishing between the countless details offered by the display. If you’re a beginner, you might be better off with a color screen.


Frequency and power

The higher the frequency, the more detailed the picture. The same goes for the wattage, as more watts are synonymous with getting a clearer image and a faster reading.
