6 Best Fish Finders with Side Scan: Top Picks Compared (2026)

Updated November 2026

Anglers who want to see structure, baitfish and bottom texture well beyond the reach of a standard sonar beam often end up searching for the best fish finder with side scan. A side scan unit sends sound pulses sideways from the transducer, so it paints a picture of the bottom and anything above it across a wide swath on each side of the boat. That makes it useful for locating submerged wrecks, rock piles, grass edges and schools that a traditional downward-facing beam would miss. This guide compares six real Amazon listings, weighing screen size, side imaging range, GPS and chart support, transducer type and how well each model suits saltwater or freshwater use.

Our Top Picks

The picks below are ordered by how closely they match the selection criteria: side imaging capability first, then screen usability, GPS and mapping, portability and overall value. Our method is research-based. We reviewed manufacturer specifications, brand reputation and patterns in owner feedback. We did not run these units ourselves, so treat the notes as a guide to what each model is built for.

RICANK Depth Finder with Temperature Portable Fishfinder Ice Fish Finder

Best for: Budget-friendly portable depth readings

This is a handheld depth and temperature finder rather than a full side-scan system. It suits shore anglers, kayak fishermen and ice anglers who want a simple readout of depth, contour and water temperature without the cost of a multi-function unit. Set expectations accordingly: it does not provide true side-scan imagery.

Key specs

• Portable handheld design with LCD readout
• Displays depth and water temperature
• Designed for lake, sea, river and ice use

Pros

• Easy to carry and deploy from shore or a kayak
• Simple readout with minimal setup
• Budget-friendly entry point for depth checking

Cons

• No true side-scan imaging, so it cannot show structure across a wide swath
• Limited mapping and no GPS features

Bottom line: A useful budget option for depth and temperature, but not a substitute for a side-scan fish finder.

Garmin 010-12380-20 Xdcr Fish Finders

Best for: Anglers focused on transducer-based chart compatibility

This listing is a Garmin transducer rather than a complete display, so it suits anglers already running a compatible Garmin chartplotter or fish finder who want to add or replace a transducer. Confirm model compatibility with your head unit before buying.

Key specs

• Garmin-branded transducer
• Designed to work with compatible Garmin units
• Transducer only; display sold separately

Pros

• Fits into an existing Garmin setup without replacing the head unit
• Brand-backed compatibility with Garmin chart features
• Useful for upgrading or repairing a system

Cons

• Not a standalone fish finder and requires a compatible display
• Side-scan capability depends on the transducer and head unit combination

Bottom line: Pick this only if you already own a compatible Garmin display and need a transducer.

Buying Guide

Side imaging range and coverage

Side imaging range determines how far from the boat you can see on each side. Many side-scan units advertise ranges measured in feet per side, and the useful range shrinks in shallow water or when the boat is moving too fast. Check the manufacturer’s stated range for your typical depth and consider how wide an area you need to cover while trolling or drifting.

Screen size and readability

Screen size affects how easily you can interpret side-imaging mosaics and split-screen views. Larger displays show more detail at a glance, but they need more console space and cost more to mount. For smaller boats, a 7-inch display is often enough, provided you can read it in bright sunlight. Look at brightness ratings and whether the screen is designed for daylight viewing.

Transducer type and included hardware

Some listings include a transducer and others are control heads only. A side-scan system needs a transducer with side-imaging elements, so confirm whether one is included before you buy. Mismatched transducers and head units are a common source of frustration, so check the manufacturer’s compatibility list.

GPS and mapping support

GPS lets you mark waypoints, track your route and overlay sonar data on a map. If you fish the same waters repeatedly, mapping is a big time-saver. Note whether the unit ships with base maps or requires separate chart cards or downloads, since that affects how useful it is out of the box.

Boat size and mounting fit

Measure your console before choosing a screen size. Allow room for the head unit, cabling and access to buttons or the touchscreen. Mounting options vary, and a stable mount reduces vibration and keeps the transducer aligned. Smaller boats often benefit from compact heads, while larger consoles can accommodate 10- or 12-inch units.

Portability and use case

If you fish from shore, a kayak or a float tube, a full side-scan system may be impractical. Portable handheld units are easier to carry and deploy but usually lack side imaging. Decide whether you need true side-scan capability or simply depth and temperature data before buying.

Durability and care

Marine electronics face spray, sun, salt and vibration. Look for units rated for marine environments and keep connectors clean and dry. Rinse displays with fresh water after saltwater trips, and avoid high-pressure washers near the transducer. Manufacturers typically publish operating temperature and water-resistance ratings, which are worth checking against your conditions.

FAQ

What is a fish finder with side scan?

A side-scan fish finder uses sonar beams aimed sideways from the transducer to produce an image of the bottom and objects on either side of the boat. It shows structure, cover and fish across a wide area, which a standard downward-facing sonar cannot do.

Is side imaging the same as side scan?

The terms are often used interchangeably, though manufacturers use different brand names. Humminbird, for example, uses MEGA Side Imaging for its high-resolution side-scan technology. Check the specifications to confirm what each model offers.

Do I need a separate transducer for side scan?

Yes. Side-scan imaging requires a transducer with side-imaging elements. Some packages include one, while control-head-only listings require you to buy a compatible transducer separately. Always confirm compatibility with the head unit.

Can side scan work in saltwater?

Many side-scan units are designed for both freshwater and saltwater, but salt spray and corrosion place extra demands on electronics. Choose a marine-rated unit and follow the manufacturer’s cleaning and maintenance guidance.

How far can side scan see?

Range varies by model, transducer and water conditions. Manufacturers publish typical ranges, but actual coverage depends on depth, water clarity and boat speed. Consult the specifications for the exact model you are considering.

What screen size should I choose?

Small boats often do well with a 7-inch display, mid-size boats suit 9 to 10 inches, and larger consoles can accommodate 12 inches. Consider both console space and how many people need to read the screen at once.

Is GPS necessary on a side-scan fish finder?

GPS is not required for side imaging, but it adds waypoint marking, route tracking and map overlays. Anglers who fish the same waters often find GPS features valuable for returning to productive spots.

Conclusion

For most anglers shopping for the best fish finder with side scan, the Humminbird XPLORE 9 GPS Fish Finder offers a sensible balance of side-imaging capability, GPS and screen size. Larger boats with console room may prefer the XPLORE 10 or XPLORE 12, while small boats are better served by the Helix 7 G4N. The RICANK Depth Finder is useful for shore and kayak depth readings but is not a true side-scan unit. The Garmin 010-12380-20 transducer suits anglers already running a compatible Garmin display. Match the screen size, mounting space and imaging needs to your boat before you buy, and confirm transducer compatibility.
