Experience the Clarity of CHIRPSTRIKER 4dv 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.
You also can upgrade to high-performance Garmin CHIRP technology, which provides crystal-clear sonar images with even more remarkable target separation and resolution from shallow to deeper depths. For better fishing, bottom contours are more visible, even at higher speeds, and signal noise can be suppressed at greater depths to provide a more timely interpretation of what´s below.
