Garmin Striker 4cv

This sonar includes a Garmin CHIRP (77/200 kHz) transducer, which provides a visibly higher level of clarity and detail for fish and structure than traditional 77/200 kHz transducers. Instead of sending just 1 single frequency, CHIRP sends a continuous sweep of frequencies, ranging from low to high, then interprets them individually upon their return. Since the frequencies provide a wider range of information, CHIRP sonar technology can create crisper fish arches with greater target separation. Garmin ClearVü scanning sonar gives you a nearly photographic, wide image of what passes below your boat. You clearly see structure, submerged objects and fish. Traditional Garmin CHIRP sonar and CHIRP ClearVü scanning sonar are combined into 1 transducer.
