Fish Finders & Sonar for Utah Lake (Small Boats & Kayaks)
A practical Utah Lake sonar guide: what features matter, easy mounting ideas, and simple battery/power options — with Amazon links.
Do you actually need sonar on Utah Lake?
If you fish from shore: probably not. If you fish from a small boat, kayak, or inflatable: sonar can save a ton of time. Utah Lake is shallow overall, but depth changes, weed edges, and "subtle" structure matter.
- Find depth quickly: stop guessing when the wind pushes you.
- Stay off the weeds: see when you drift into the salad.
- Repeat a drift: re-run the productive line instead of wandering.
The 80/20 features (what matters)
- GPS + basic maps: drop waypoints, repeat drifts, mark submerged hazards.
- CHIRP 2D sonar: good enough for depth + bottom hardness + bait/fish marks.
- Clear screen in sun: brightness matters more than extra modes.
Side imaging / live sonar can be awesome, but its expensive and heavier. For most Utah Lake fishing, a simple GPS fish finder is plenty.
Recommended fish finders (Amazon picks)
These are Amazon search links filtered by common models/specs. Pick your price point and focus on a clean install.
1) Budget GPS fish finder (simple + reliable)
2) Screen upgrade (easier in wind + sun)
3) Mounting (dont overthink it)
4) Power (simple options that work)
Most small fish finders are happy on 12V. The two common approaches: a small sealed/AGM battery or a compact LiFePO4.
- 12V 7Ah sealed/AGM battery (budget + widely available)
- 12V LiFePO4 10Ah battery (lighter)
- Small waterproof battery box
If you only change one thing: mount the screen where you can read it in sun and wire it cleanly. A cheap unit installed well beats an expensive unit you cant see or trust.
