Best Fish Finders for Kayak & Small-Boat Inshore Fishing
On a kayak or small skiff you want a unit that's bright in Florida sun, has GPS to mark that oyster bar or dock, and doesn't need a boat-sized battery. The 7-inch class is the sweet spot. Here's how the main players stack up.

Garmin Striker Vivid 7cv: best for most kayak anglers
Who it's for: anglers who want sharp down-imaging and GPS waypoints without paying for charts. The GT20-TM transducer is small and easy to mount through a scupper or on an arm, and Quickdraw lets you build your own contour maps of a creek or lake as you fish.
- Best price-to-picture ratio
- Compact mount fits kayak rails
- No preloaded maps and no side imaging (that's the 7sv)

Humminbird Helix 7 CHIRP GPS G4: best if you want real charts
Who it's for: anglers who fish big water like the Indian River Lagoon or Lake George and want Navionics or LakeMaster charts on a microSD card. AutoChart Live maps as you go. Step up to the DI or SI versions if you want imaging.

Garmin ECHOMAP UHD2 73sv: best do-everything 7"
Who it's for: the serious kayak or skiff angler. Side imaging finds docks, brush piles and channel edges fast, the touchscreen comes with preloaded maps, and it can run LiveScope later if you want live sonar.

Lowrance Elite FS 7: best path to live sonar
Who it's for: anglers planning to add ActiveTarget 2 live sonar. Lowrance markets the Elite FS as its most capable compact display for kayaks, and an All-Season Pack with a portable power pack is available.

Florida inshore notes
- Shallow water changes everything. In 2–6 ft of water in the lagoons, down-imaging beats side imaging for spotting grass edges, potholes and oyster. Side imaging earns its keep in rivers and lakes.
- Salt kills connections. Rinse the unit, the mount and the power plugs with fresh water after every trip, and put dielectric grease on the plugs.
- Power: a small 12V lithium (LiFePO4) battery in a waterproof box runs a 7" unit all day. Check the unit's current draw before you size the battery.
- Mark everything: docks that hold snook, the drop next to a bar, tide-dependent creek mouths. GPS waypoints are half the value on a kayak.
- Read the size and slot limits on FWC before you keep fish. Redfish, snook and trout rules differ by region.
