Buying Guide - Side Imaging Fish Finders

As far as sonar technology is concerned, side imaging is probably the most advanced feature you’ll ever come across. This is because, using the images collected under water; you can easily access an uninterrupted view of your area of target. But in order for that to happen, you need to first of all invest in the best side imaging fish finders and here’s how to go about finding the best deal on the markets.

Your fishing boat

Ordinarily, most fish finders are designed for use in bass boats, motor boats, and vessels of a similar design. If you’d, therefore, want to use your unit on an inflatable fishing kayak, it’s always important to note that some modifications may be needed. Fortunately, there are many different guides available freely online and you can always refer to them in order to make the most out of your fishing gear.


One of the unique attributes of side imaging technology is that it uses a transducer to shoot out sound waves in two ways. This way, you can scan a larger surface than you would using down imaging technology. Not all fish finders come with transducers. Therefore, it’s important to double-check that your preferred unit comes with a transducer, otherwise, you’ll find yourself ordering for a new transducer and that will mean spending more dollars and waiting for a few more days.

Screen Size

If you opt for an old model, chances are that you’ll end up with an old-fashioned fish finder with a screen resembling that of a mobile phone. On the contrary, modern side imaging fish finders tend to offer larger screens. Wider screens come in handy at providing accurate readings thanks to a higher resolution and improved color contrast.


In addition to the size of the screen, using a finder that has a backlit screen makes it a whole lot easier for you to access data even in direct sunlight. Working with a unit that doesn’t have this all-important feature will make it extremely difficult for you to view the screen details and you’d need to go to a dark area to get the hang of it. Of course, you don’t want to have such an occurrence happening to you when you’re in the middle of a lake and that’s why it’s important to only settle for a backlit-screen model.


Last but definitely not least is the frequency and power of the fish finders. The factors here entirely depend on your style of fishing. If you like fishing in deep waters, then a 50kHz unit would be ideal. On the other hand, if looking for a 200 kHz then it’d be ideal to try fishing in shallow reservoirs. As far as power is concerned, usually the rule is that, the greater the wattage, the better.

Which Is Best For You?

All the side imaging fish finders that made it to this are worth their salt – no doubt. However, when our experts spent time examining each one of them, they found glaring differences. At the end of the day, the Humminbird 409640-1 Helix scooped the top position as one offering the best value for money. That said, the Lowrance HDS-9 Gen2 Finder stands out as a high-quality package. So if you’re a pro we’d highly recommend giving it a try.

Final Thoughts

The next time you pack up your fishing gear in readiness for your fishing trip, be sure not to leave your fish finder behind. This is the only technology that gives you the chance to eavesdrop on the fish so you can plan your casting better. Ultimately, this gives you an unparalleled advantage and makes it extremely easy to bring more catches home.

All you, therefore, need to do is focus on getting yourself a high-quality unit that supplies you with reliable data. Remember, not all units come with a transducer, so be sure to confirm this fact prior to making your purchase. All the best in your shopping and research mission, we hope you end up with a unit that provides you with nothing but the best value for your money.
