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.

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.
