The short answer
For most small-boat anglers on a budget, the Garmin Striker Vivid 5cv is the best value: CHIRP, ClearVü scanning sonar, GPS and a sharp 5-inch screen. If you want lake maps included, the Lowrance Eagle 5 is the pick. On the tightest budget, the Garmin Striker 4 still covers depth, fish and waypoints.

How we built this guide
We compared current budget models using manufacturer specs, published screen and sonar data, owner reports and long-term reviews from small-boat anglers. We did not do hands-on testing, so we note where owner experience lines up with, or differs from, the spec sheet.
What can a budget fish finder really do?
A good budget unit shows depth, bottom, fish arches and water temperature. Most current models add GPS so you can mark spots and see your speed.
What you give up is screen size, preloaded maps and side imaging. On a 12 to 16 foot jon boat or a canoe, that is often fine. You are usually fishing a smaller lake and moving slowly.
Garmin Striker Vivid 5cv
The 5cv is the sweet spot of Garmin’s budget line. It has a 5-inch color screen at 800 by 480 resolution, CHIRP traditional sonar, ClearVü scanning sonar and GPS. Garmin’s Quickdraw lets you record your own depth contours as you drive.
The catch: no preloaded charts. Owners who fish big lakes often wish they had maps. Owners who fish small lakes often do not miss them.

Lowrance Eagle 5 with SplitShot
The Eagle 5 is Lowrance’s entry line. The SplitShot transducer gives CHIRP plus DownScan imaging, and many bundles include C-MAP inland charts. If maps matter on a budget, this is the one to look at.

Garmin Striker 4
The Striker 4 has been around for years for a reason. It is cheap, simple and has CHIRP and GPS. The 3.5-inch screen is small, so it suits a canoe or a second unit more than a main display.

Humminbird HELIX 5 CHIRP GPS G3
The HELIX 5 G3 gives Dual Spectrum CHIRP, GPS and a built-in basemap. Humminbird’s interface is clean, and this unit is a common first fish finder for small boats.

Garmin Striker Plus 4cv
The Plus 4cv brings ClearVü scanning sonar to a 4.3-inch screen. It is a good fit for tight consoles where a 5-inch unit will not fit.

Who it’s for / who should skip it
- A budget unit is for: jon boats, canoes, small aluminum boats, rentals and second units.
- Skip budget if: you fish big water, want side imaging, or plan to add live sonar. Look at our fish finder chartplotter roundup instead.
- Skip the 3.5-inch size if: your eyes struggle with small screens. Go 5 inches.
What actually matters when buying
- Screen size and resolution: 5 inches is the practical minimum for split screens.
- Down imaging: ClearVü or DownScan helps you see brush and stumps clearly.
- GPS: lets you return to good spots and shows speed for trolling.
- Maps: preloaded charts are rare at this price. Decide if you need them.
- Marketing noise: fish icons and huge depth claims are not useful.
Watch-outs
- Budget units have no networking, so no live sonar later.
- Transom transducers on jon boats can lose signal at speed if mounted wrong. See our transducer fixes guide.
- You still need a 12V battery. A small lithium pack works well.
- Some “deal” listings are older versions. Check the model number.
How do I choose between these?
Start with maps. If you want charts out of the box, the Lowrance Eagle is the easy choice. If you do not need them, Garmin’s Striker Vivid line has the strongest sonar for the money.
Then think about screen size. Measure your console or mounting spot. A 5-inch unit is noticeably easier to read than a 3.5-inch one when running split screens.
Which should you choose?
- Choose the Striker Vivid 5cv if you want the best sonar for the money.
- Choose the Eagle 5 if you want charts on a small budget.
- Choose the Striker 4 if you want the cheapest reliable unit.
- Choose the HELIX 5 G3 if you like Humminbird’s interface or plan a Minn Kota setup.
Common questions
Is a cheap fish finder worth it?
Yes, for small boats. Even a basic CHIRP unit shows depth, bottom and fish, which changes where you fish. Owners often say their first fish finder was the biggest upgrade they ever made.
Do budget fish finders have GPS?
Most current budget units from Garmin, Lowrance and Humminbird include GPS. Older or ultra-cheap units may not, so check the specs.
Can I use a budget fish finder on a kayak?
Yes. The Striker and Eagle lines are popular kayak picks. See our best kayak fish finders guide.
Which budget fish finder has maps?
Lowrance Eagle bundles often include C-MAP charts. Humminbird HELIX G3 units include a basemap. Garmin Striker units have no charts, only Quickdraw contours.
