Humminbird 409700-1


Compared to the alternative we’ve showcased above, this one is considerably more affordable. Normally, a low price does not necessarily mean low quality.

The fact of the matter is that this is a monochrome sonar which does not address the needs and requirements of advanced users. By contrast, it might be the right choice for people who are still having trouble figuring out whether or not they need to use a fish finder. Some of these individuals might not be willing to wreck their entire budget over buying a unit, regardless of its specs.

This unit has a 5-inch 240 by 240 screen, with 12 levels of grayscale and a dual beam frequency. Users can select 83kHz for fishing in deep and murky waters and 200kHz if they’re practicing in shallow lakes.

The maximum depth capacity of this variety is estimated at 800 feet.

In spite of its limited capabilities and average display, the Humminbird 409700-1 is rather popular amongst buyers, as they claim it works well and is easy to install.

Humminbird 409590-1


It would have been impossible for us to leave out this model from this list, as it is probably the most affordable yet perfectly capable Humminbird sonar we’ve analyzed. Granted, it might not be as advanced as other modern alternatives, but it will do its job as well as possible.

Buyers are advised that the Humminbird 409590-1 does not have GPS, time or MPH. The unit works as a 2D sonar and displays just the depth and the water temperature.

The pack includes the XNT 9 20 T transducer with dual frequency. As is the case with the formerly described variety, the frequency of this one can be customized between 83kHz and 200kHz.

In conclusion, this variety is destined for boaters and anglers who require a dual beam sonar and probably already own a fish finder. On the other hand, if you trust your abilities well enough, you might benefit from buying this sonar alone, as most of the people who did claim it is dependable and offers great value.

Buying guide


Looking for the best fish finders out there on the market? If so, you’ve come to the right place. We find great pleasure in giving out a helping hand to prospective buyers, which is why we have put together a short buying guide. Remember to consider your needs and preferences before buying a certain model. If your time allows it, go over some sonar reviews.


Power and frequency

If you plan on fishing in shallow water, power isn’t all that important. Yet frequency is. The higher the power, the better. With frequency, things aren’t so easy as to say that one type is great for all waters. 50kHz might be the right choice for deep waters, whereas 200kHz is great for shallow lakes.


Screen size and resolution

Gone are the days when fishfinders came with screens similar in size with the ones of old cell phones. Nowadays, we recommend buying a unit that has a screen at least 5-inch wide.

The minimum resolution that you can use to actually understand what’s going on under the boat is 240 by 160 pixels. Anything lower than that will make you focus on interpreting the image instead of concentrating your efforts on the actual catch.
