The Garmin STRIKER 4 brings together a 3.5-inch color display, built-in high-sensitivity GPS, and CHIRP sonar in a compact, keypad-driven fishfinder suited for fresh and saltwater use. Mark waypoints on the fly, view boat speed, rewind sonar history to tag spots you passed over, and share locations with compatible STRIKER and echoMAP units. Smooth Scaling keeps sonar imagery continuous through depth changes, and the built-in flasher handles vertical jigging and ice fishing without an extra device. The included 77/200 kHz CHIRP transducer produces noticeably sharper fish arches and cleaner target separation than standard dual-frequency units, and the head unit accepts optional GT8 or GT15 CHIRP transducers for added depth and resolution.
