Description  The STRIKER™ Plus 4cv fishfinder with a bright 4.3” display and built-in GPS features Garmin CHIRP traditional sonar, Garmin CHIRP ClearVü™ scanning sonar and Quickdraw Contours map drawing software, which stores up to 2 million acres of content with 1-foot contours. Built-in GPS lets you mark and navigate to waypoints and shows your boat’s speed. Garmin Quickdraw Contours - Nobody knows the waters you fish better than you and your fellow fishermen. While you are trolling the shorelines and the depths, Quickdraw Contours mapping software creates HD fishing maps of the places you’ve been. No special knowledge is required. STRIKER™ Plus 4cv can now store up to 2 million acres of your Quickdraw Contours maps with 1-foot contours. CHIRP ClearVü Clarity - The STRIKER™ Plus 4cv fishfinder includes Garmin CHIRP technology combined with Garmin ClearVü™ scanning sonar for a nearly photographic, wide image of what passes below your boat. You clearly see structure, submerged objects and fish. Paired with Garmin CHIRP traditional sonar for remarkable target separation, this transducer will help you catch more fish. GPS Fishfinder - The built-in, high-sensitivity GPS finds and maintains your position anywhere you go on the water. The GPS allows you to mark waypoints for different locations. So, if the fish are biting in one spot, you can mark it, and return to it on your next trip. Mark docks, boat ramps and other locations on the lake, and create routes back to them for your next trip. GPS also allows STRIKER™ Plus 4cv to show your speed on screen, so you can be sure you’re trolling at the right speed for the lure you’re using or in wake-controlled areas. Built for You - The STRIKER™ Plus 4cv fishfinder makes fishing a breeze, and it’s built to work in any environment. The bright, sunlight-readable display gives you a clear view of what is below your boat, even on the brightest days. And the larger screen gives you a better view of what is happening below the boat. The intuitive user interface makes it simple to navigate to whatever feature you need, so you are ready for anything on the water.  Features 4.3" QSVGA Display - 272 x 480 pixels Dimensions : 9.8 x 17.4 x 4.5 cm / 0.3 kg Waterproof IPX7 Integrated GPS Dual-beam (77/200 kHz) sonar capable Dual-frequency (50/200 kHz) sonar capable Frequencies supported : Traditional: 50/77/200 kHz / CHIRP (mid and high) / ClearVü 260/455/800 kHz Transmit power : 300 W (RMS) Water temperature sensor included Split-screen zoom
