Precision on the water gives you the advantage. Make the Humminbird HELIX 7 Sonar GPS your underwater eyes and navigation guide, and you'll always have a clear picture of what's going on. Unbelievably clear, in fact. This is true widescreen sonar/GPS at its brightest and crispest, with high-def 480 x 800 pixel resolution supported by Humminbird's advanced Glass-Bonded Display. No matter how high or low the sun, you can see the screen clearly, brightly, without glare, from any angle. And the 16:9 ratio display offers the optimum aspect for viewing sonar and cartography simultaneously and getting all the detail you need. The HELIX's processor has been beefed up too, with double the RAM for lightning-quick waypoint management and screen refreshes. With 500 watts RMS/4000 watts peak-to-peak power, the Humminbird HELIX 7 Sonar GPS has the punch to deliver crystal-clear SwitchFire® Sonar images, manage up to 2500 waypoints/45 routes, and support LakeMaster®, AutoChart®, AutoChart Pro, and Navionics® Gold/HotMaps mapping programs via its single Micro SD card slot. Includes internal precision GPS and built-in Contour XD map. 2D sonar depth: 600'; 1500' with XD transducer (not included).
