You’re on the water, and you know fish are holding near that submerged log, but your current fish finder only shows a fuzzy bottom. You’ve heard side scan can reveal structure and fish like never before, but you assume it costs a fortune. The truth is, you can get side imaging capabilities without emptying your wallet. In this guide, we’ve reviewed the most affordable fish finders with side scan, so you can see what’s below and beside your boat without the premium price tag.
We’ve evaluated a range of models from top brands like Humminbird, Lowrance, and Venterior, focusing on those that offer side scan or similar imaging features at budget-friendly prices. Whether you’re a kayak angler, a shore fisherman, or a small boat owner, we’ve got you covered. Let’s dive into the best cheap side scan fish finders of 2026.
Buying Guide: What to Look for in a Budget Side Scan Fish Finder
When you’re shopping for the cheapest fish finder with side scan, it’s easy to get overwhelmed by specs. But you don’t need to be a sonar expert to make a smart choice. Here are the key factors we considered in our review.
Side Scan vs. Down Scan: Know the Difference
Side scan uses sonar beams that fan out to the sides of your boat, giving you a wide view of the underwater landscape. Down scan, on the other hand, sends a beam straight down for a detailed, photo-like image of the bottom. Many budget models include down scan but not true side scan. If you specifically want side imaging, look for models that explicitly mention “SideScan” or “Side Imaging.” For a deeper dive, check out our comparison of down imaging vs side imaging.
Transducer Quality and Beam Angle
The transducer is the heart of any fish finder. A wider beam angle covers more water, which is crucial for side scan. Look for transducers that offer multiple frequencies, like CHIRP, to get better target separation. In our list, the Lowrance HOOK Reveal 5 SplitShot uses a SplitShot transducer that provides both high CHIRP sonar and down scan imaging, which is a solid compromise for budget anglers.
Display Size and Readability
A small screen can make it hard to see the details that side scan provides. We recommend at least a 5-inch display for decent visibility. The Humminbird Helix 5 G3 has a 5-inch screen and is known for its crisp display even in sunlight. If you’re fishing from a kayak, you might prefer a portable unit with a smaller screen, but don’t sacrifice clarity. Check out our guide on how to read a fish finder to get the most from your display.
GPS and Mapping Features
GPS is a game-changer, as it lets you mark waypoints and return to productive spots. Many budget side scan fish finders include basic GPS, but some don’t. If you fish on large lakes or want to create your own contour maps, consider models like the Lowrance Elite FS 7 with Active Imaging, which comes with C-MAP charts.

Final Thoughts
Finding the cheapest fish finder with side scan doesn’t mean sacrificing quality. For anglers who want true side imaging without a huge investment, the Humminbird Helix 5 G3 GPS Fish Finder offers excellent value with its Dual Spectrum CHIRP and down imaging. If you prefer a portable, castable option that’s perfect for kayak or shore fishing, the Venterior Portable Rechargeable Fish Finder is a versatile and affordable choice. Both models deliver reliable performance to help you locate fish and structure, so you can spend more time catching and less time guessing.
Frequently Asked Questions
What is the cheapest fish finder with side scan?
The cheapest fish finders with side scan typically start around the $300 range. Models like the Humminbird Helix 5 G3 offer side imaging and down scan at a budget-friendly price. However, some portable castable fish finders like the Venterior are even more affordable but may not have true side scan, just down scan.
Is side scan worth it on a budget fish finder?
Absolutely. Side scan helps you cover more water and find fish-holding structure that you’d otherwise miss. Even on a budget, side scan can dramatically improve your fishing efficiency, especially on larger bodies of water.
Can I use a side scan fish finder on a kayak?
Yes, you can mount a side scan transducer on a kayak, but it requires a special mount to keep the transducer in the water. Many kayak anglers prefer portable units like the LUCKY or Venterior that can be cast or attached to the hull. For more tips, see our guide on installing a fish finder on a kayak.
Do I need GPS with a side scan fish finder?
GPS is not required for side scan to work, but it’s a huge advantage. It lets you mark spots, create routes, and see your position on a map. Many budget fish finders include basic GPS, so it’s worth looking for one that does.
