Garmin STRIKER 4 3.5" Fishfinder | CHIRP Sonar | GPS

🐟 Entry-level 3.5" CHIRP sonar + GPS fishfinder. Button controls, no touchscreen, no mapping, just simple, reliable fish-finding at the lowest Garmin price tier.

Garmin STRIKER 4

The Garmin STRIKER 4 is the entry-level Garmin fishfinder, the starting point of the lineup at $159. It's a 3.5" color fishfinder with CHIRP traditional sonar and built-in GPS for waypoint marking. Not a touchscreen, this uses buttons. Not a chartplotter, there are no maps. It marks fish, shows bottom depth, reads water temperature, and tracks waypoints. That's it, and for a lot of anglers, that's exactly what's needed.

This is the right unit when you want a simple, reliable Garmin fishfinder for kayaks, jon boats, canoes, ponds, or as a secondary unit on a larger boat. CHIRP sonar at this tier isn't a marketing gimmick, it's the same CHIRP technology that costs $2,000 at the premium tier, delivered at the lowest possible entry point. You get cleaner target separation than single-frequency sonar, and it works in freshwater, saltwater, and ice fishing applications.

Who This Is For

This unit is best for beginner anglers, kayak anglers, jon boat owners, pond anglers, bank fishermen with portable setups, anglers buying a gift, and anyone who needs a reliable fishfinder for under $200. One step up: the STRIKER Plus 4 (~$180) adds Quickdraw Contours for mapping lakes as you fish and a slightly larger 4.3" screen. Two steps up: the STRIKER Vivid 4cv (~$200) adds ClearVü down imaging and a brighter color display. Meaningful steps up, but the STRIKER 4 is the right answer when you just need the basics.

Choose This If...

• You need a basic CHIRP fishfinder for under $200, this is the price entry point for the Garmin ecosystem.
• You fish kayaks, jon boats, canoes, or small ponds, the 3.5" size fits anywhere, and the low power draw works on tiny batteries.
• You don't need mapping, just waypoints and depth. If you want lake contour mapping, step up to the STRIKER Plus 4.
• You're buying a gift or a first fishfinder, simple menus, reliable performance, low price.
• You're looking for a secondary unit, add to a larger boat as a backup, or a bow-mount setup paired with your trolling motor.
• You want ice fishing compatibility, add the ice transducer accessory and this becomes an ice fishing unit.
