STRIKER™ 4 Fishfinder Combo with SuncoverSTRIKER 4 fishfinder 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.Features:3.5-inch CHIRP Fishfinder with GPSEasy-to-use 3.5-inch color fishfinder with built-in, high-sensitivity GPSFind fish; mark and return to hot spots, docks and rampsConvenient keypad operationIncludes CHIRP (77/200kHz) sonar transducer; transmit power (200W RMS)/(1,600W peak-to-peak)Upgrade to high performance CHIRP with a GT8 or GT15 transducer (each sold separately)Multi-language capabilityFinding fish is easier than ever with STRIKER 4 fishfinder.
