Plus, it has a built-in flasher and displays speed data. Includes tilt/swivel mount plus transom and trolling motor mounting hardware and cable. Experience the clarity of CHIRP:Striker 7sv includes a Garmin high wide CHIRP 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 one 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.Clear Scanning Sonar Images:Garmin ClearVü scanning sonar gives you a nearly photographic, wide image of what passes below your boat. Garmin SideVü scanning sonar gives you a crisp, clear view of what lies off to each side of your boat. You clearly see structure, submerged objects and fish. High wide CHIRP sonar and both ClearVü and SideVü scanning sonars are combined into one transducer.Mark Spots with high-sensitivity GPS: Unlike regular fishfinders, Striker fishfinders have built-in, high-sensitivity non-mapping GPS to locate your current position quickly and precisely, then maintain your GPS location anywhere you go on the lake. More importantly, they allow you to mark spots where the fish are biting so you can return to them again in the future. You also can mark docks, boat ramps and other locations on the lake. Just follow the path created on your screen to return to them whenever you wish.Check your speed on-screen: You can quickly and easily see your boats speed on the
