Introducing the Garmin Striker 4 3.5-inch Portable CHIRP Fishfinder with GPS — a compact, color-display unit that brings serious fishfinding performance to a small, easy-to-transport package. Perfect for kayak or canoe fishing, ice trips, or as a dependable secondary unit on larger boats, it shows you where to fish with clarity and precision.
-
CHIRP sonar clarity with a dedicated 77/200 kHz transducer — delivering crisper fish arches and better target separation. Transmit power is 200 W RMS / 1,600 W peak-to-peak for impressive imaging, and you can upgrade to high-performance CHIRP with GT8 or GT15 transducers (sold separately).
-
Built-in GPS — a high-sensitivity receiver pins your current position quickly and keeps it for reference on the lake, river, or open water.
-
Mark, save, and navigate — effortlessly mark hot spots, docks, boat ramps, or favorite spots and return to them later using the waypoint map and guided navigation.
-
Share and compare — transmit your waypoints and routes to other STRIKER or echoMAP chartplotter combos for collaborative fishing trips.
-
Smooth Scaling and sonar history — uninterrupted imagery when switching depth ranges, plus Sonar History Rewind to scroll back and mark waypoints you may have missed.
-
Portable kit included — carrying case, rechargeable battery, CHIRP (77/200 kHz) transducer, tilt/swivel mount, and transom/trolling motor mounting kit for versatile mounting options.
-
Versatile mounting and use — designed for quick setup on small craft and capable of expanding with higher-end CHIRP options for even sharper sonar across depths.
Experience the clarity of CHIRP and the reliability of Garmin GPS on the water. The STRIKER 4 helps you locate fish, track your speed on screen, and navigate back to productive spots with confidence — all in a portable, user-friendly package.
