Buying guide


If you’ve been looking for the best fish finder, you’ve come to the right place. For your consideration, we have put together a short list of things you need to consider if you want to make the right call. Always remember that your needs and preferences have to come first whenever you’re making a purchase, which is why you need to read as much info as possible.

A lot of details such as frequency, wattage, size of the screen, down and side imaging contribute to picking out the right model. Just have a look at what we think is most important.




Screen-related features

Even with side imaging fish finders, screen size matters quite a lot. If you pick an older model that’s cheap and somewhat old-fashioned, you’re likely to purchase one that comes with the screen size of an ancient mobile phone. It might do a good job at providing accurate readings, but you might have a little trouble understanding them.

Resolution and color are two other factors to consider. The higher the resolution, the more detail you’ll be able to see. Color-screen fish finders can help you to better understand the underwater environment. Units that feature grayscale displays are usually destined for people on a tight budget.


Frequency and power

The same goes in the case of both of these specs. The higher they are, the better. Actually, in the case of frequency the matter might be a little more subjective than you could be tempted to think. A frequency of 200 kHz will get you great readings in shallow water, while one of 50 kHz is perfect for seeing your catch in deep waters. Some modern models come with customizable frequencies, which gives users the freedom to pick the right one.

The more watts, the merrier the user. Extra power is synonymous to faster readings and crystal clear images.



Basic fish finders are perfect choices for beginners, but most buyers tend to specialize in their craft. Sooner or later, they’ll start looking for more advanced models. All things considered, one of the most acclaimed feature of these devices is downscan/down imaging, which is best combined with side-imaging. Down imaging allows buyers to visualize picture-like images, while side imaging helps them understand what’s happening around the boat.

For example, some models are capable of providing readings which result from scanning the area up to 240 feet on both sides of the location of the boat. That sure comes in handy, doesn’t it?

Buying guide


What’s the best side scan sonar for the money? If you’ve struggled to answer this question but find it hard to make up your mind on account of the many models that now exist on the market, we’re here to help. Check out the following buying guide to correlate your needs and requirements to the features you’re looking for in a unit.

Side scan sonar




Depth is one of the first consideration when buying the best fish finders. Some models can offer readings of up to 200ft, while others can do the same up to 3000ft, provided they have the right transducer.


Screen size and resolution

To accurately see what’s going on under the boat, you need a screen size of at least 4 inches. The screen resolution also plays a major part in displaying crisp images, as does your personal preference between a color or a black and white display.


GPS and mapping

GPS and mapping aren’t two mandatory features, but if you want to know you’ll arrive home safely no matter the weather conditions, they’re definitely desirable.


Power and frequency

The more power, the better. In shallow waters, a high frequency is more important than a lot of power. On the contrary, fishing in deep, murky waters requires a high wattage.

Lowrance LSS-2


3.Lowrance 000-10800-001 LSS-2This is a fishfinder module that is compatible with the vast majority of HDS units. It would have been impossible to leave this variety out from this list, as it’s remarkably inexpensive compared to the other two devices we’ve described earlier on.

Furthermore, considering that it is more than capable of providing HD images of the bottom and of the fish, it has gathered quite a wide angle of appreciation over the years.

One of the most attractive specs of this mode is the StructureScan feature, which provides images of targets and of their shadows. This way, the displayed picture is far more realistic than the one of other units in the same line.

The manufacturers are offering a 2-year consumer warranty on both parts and labor.

The package contains the actual LSS-2 Sounder module, an owner’s manual, a power cord, a 6-inch Ethernet cable, and a transom-mount Skimmer transducer.

The Lowrance variety might not be as popular as the previously mentioned side scan sonars, but it’s fairly well-known for its performance and capabilities.
