A $500 budget is probably one of the best places to be when shopping for a fish finder because you can get serious fishing technology without moving into expensive $1,000+ marine electronics.
You can now find units with 5-inch and 7-inch displays, CHIRP sonar, Down Imaging, GPS, detailed mapping, and custom contour creation around this price.
However, not every fish finder under $500 gives you the same features.
Some put more of the budget into the display, while others give you better maps or more advanced sonar.
So you need to decide whether screen size, mapping, sonar detail, or portability matters most to the type of fishing you actually do.
These are the fish finders I would currently consider first if the maximum budget is $500.

Best Fish Finders Under $500
When you are spending close to $500, there are a few features I would expect unless you are buying the unit for a very specific purpose.
Those include:
- A good color display
- CHIRP sonar
- GPS
- Waypoint marking
- Down scanning or useful mapping
- A transducer included with the package
You also need to think about where you are installing it.

1. Best Overall Fish Finder Under $500: Garmin ECHOMAP UHD2 53cv
The Garmin ECHOMAP UHD2 53cv gets the top position because it gives you both good sonar and actual chartplotter functionality without crossing the $500 limit.
The included GT20-TM transducer gives you traditional Garmin sonar and ClearVü scanning sonar.
But the main reason to buy this instead of a cheaper STRIKER is the mapping.
The U.S. inland version comes with Garmin Navionics+ maps and gives you GPS navigation rather than simply waypoint marking on a blank background.
The 5-inch display is also compact enough for smaller boats without feeling tiny.
Current U.S. pricing is $449.99 at retailers including Bass Pro Shops, Cabela's, Walmart, and West Marine.
Special features:
- Garmin Navionics+ maps
- 5-inch display
- Traditional sonar
- ClearVü
- Built-in GPS
- Wi-Fi and ActiveCaptain support
2. Best Large Screen Fish Finder: Garmin STRIKER Vivid 7cv
Some anglers care more about seeing sonar clearly than having detailed preloaded charts.
If that sounds like you, the STRIKER Vivid 7cv makes a lot of sense.
You get a full 7-inch display for around $419.99, which gives you considerably more viewing space than most units in this price range.
The unit supports traditional CHIRP and ClearVü sonar, and you can display different sonar information together without everything becoming cramped.
GPS, waypoint marking, routes, speed information, and Quickdraw Contours are also included.
What you do not get is the same preloaded charting package found on the ECHOMAP.
Special features:
- 7-inch display
- Traditional CHIRP
- ClearVü
- Built-in GPS
- Quickdraw Contours
- Good value for screen size
3. Best Down Imaging Fish Finder: Humminbird HELIX 5 CHIRP DI GPS G3
The HELIX 5 CHIRP DI GPS G3 is the one I would consider if you care a lot about identifying structure directly below the boat.
It combines Dual Spectrum CHIRP sonar with CHIRP Down Imaging.
That allows you to use normal sonar when searching for fish and switch to the more detailed Down Imaging view when trying to understand brush, timber, rocks, or other structure.
The unit also has GPS, Humminbird Basemap, AutoChart Live, and support for additional premium chart products.
At $399.99 direct from Humminbird, it stays comfortably inside the $500 budget.
Special features:
- CHIRP Down Imaging
- Dual Spectrum CHIRP
- 5-inch display
- Internal GPS
- Humminbird Basemap
- AutoChart Live
4. Best Easy-to-Use Fish Finder: Lowrance Eagle 5 SplitShot HD
Fish finders can become frustrating when you spend more time changing settings than actually fishing.
The Eagle 5 SplitShot HD is built around making the setup easier.
Its SplitShot HD transducer combines CHIRP sonar and DownScan Imaging while FishReveal helps show fish targets against the DownScan image.
Autotuning sonar reduces the amount of manual adjustment you need as conditions change.
The newer IPS display is also useful when the fish finder is mounted off-center because the screen remains easier to see from different angles.
Current U.S. retail listings have the Eagle 5 SplitShot HD around $349.99, depending on the mapping package.
Special features:
- SplitShot HD transducer
- CHIRP sonar
- DownScan Imaging
- FishReveal
- Autotuning
- IPS screen
5. Best Portable Fish Finder Under $500: Deeper PRO+ 2
The Deeper PRO+ 2 is completely different from the traditional fish finders above.
There is no dedicated display.
Instead, the sonar connects directly to your smartphone over its own wireless connection and displays the information through the Fish Deeper app.
That makes it particularly useful if you fish from several different places such as a kayak, canoe, inflatable boat, dock, or shoreline.
The unit has three beam frequencies and built-in GPS, and you can create bathymetric maps of the water you fish.
It is also far below the $500 limit, with current U.S. listings well below $300.
Special features:
- Extremely portable
- Three beam frequencies
- Built-in GPS
- Depth mapping
- Smartphone display
- No permanent installation
Is a $500 Fish Finder Worth It?
For most recreational anglers, $500 is enough to get the features that actually make a major difference.
Going above this price normally starts giving you larger displays, networking options, better side scanning systems, live sonar compatibility, and more advanced chartplotting.
Those features can absolutely be useful.
But if your main goal is finding fish, identifying structure, marking productive spots, and navigating lakes, you do not necessarily need to spend $1,000.
What Should You Look for in a Fish Finder Under $500?
I would prioritize the features based on how you fish.
If you move around unfamiliar lakes, get something with proper mapping such as the ECHOMAP UHD2 53cv.
If you fish familiar water and mainly want sonar visibility, the STRIKER Vivid 7cv gives you more screen for your money.
If you fish structure heavily, Down Imaging becomes much more important.
And if you regularly change between kayaks and different boats, portability may matter more than screen size.

Conclusion
You can get a very capable fish finder without spending more than $500.
The Garmin ECHOMAP UHD2 53cv gives you the best overall balance of sonar, GPS, and proper mapping, while the STRIKER Vivid 7cv is better if you want the largest practical screen for the money.
The most important thing is choosing the features that match the way you actually fish instead of paying for technology you will never use.
