The Garmin STRIKER 4 packs a 3.5-inch color display, built-in high-sensitivity GPS, and CHIRP sonar into a straightforward keypad-operated unit. Mark waypoints, track boat speed, scroll back through sonar history, and share favorite spots with compatible STRIKER and echoMAP combos. Smooth Scaling graphics keep imagery continuous across depth-range changes, while the built-in flasher makes vertical fishing and ice fishing practical without a separate device. The included 77/200 kHz CHIRP transducer delivers noticeably sharper fish arches and better target separation than conventional dual-frequency transducers; for even greater resolution and depth performance, the unit is compatible with optional GT8 or GT15 transducers (each sold separately).
