The HELIX 7 CHIRP DI GPS G2 by Humminbird features a new user interface and operating system. See fish and vertical lure presentations by viewing CHIRP Down Imaging and SwitchFire Sonar side-by-side on the wide, 16-bit display. The reliable, internal GPS offers 2500 waypoints and 50 routes, so you can return to your most productive spots time and time again. CHIRP Down-Imaging | Get a fish-eye’s view of what’s happening below your boat. These incredible images are created with high frequency sound waves emitted in ultra-thin slices. The sonar returns from these waves produce a “portrait.” As you patrol the water, you’ll watch fish, reefs, timber, brush, bridge pilings, rocks, and any other structure or cover pop with stunning detail. CHIRP Digital Sonar | View low, medium and high CHIRP ranges, either individually or all at once. Dial in a specific kHz, search a defined range or cover the entire spectrum, it’s up to you. Because it uses a broader range of frequencies, Humminbird CHIRP also delivers extreme target separation, lower noise and richer, higher-resolution images. SwitchFire | This puts anglers in complete command of how their sonar returns appear. With two unique display modes, Clear Mode and Max Mode, you can adjust to your fishing conditions on the fly. Add or remove detail, account for water depth, temperature and turbulence, even experiment with lure presentations all at the push of a button. SwitchFire adds a whole new dimension to 2D fish-finding. DualBeam Plus | Two beams combine for great detail and a wide coverage area. Use the narrow beam for high-accuracy returns and bottom. Use the wide beam when you want a larger search area. AutoChart Live | Make a map where there is no map. AutoChart Live allows you to create richly detailed maps of your favourite fishing spots in real-time. Map the water as you drive the boat, with eight hours of built-in recording time.
