Maximise your angling experience with this HELIX 5.  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. CHIRP Side-Imaging | Gain a 180° side to side perspective on the world below the surface. In an instant, the ultra-thin beam scans the area up to 240 feet to the left and right of your boat location—for total coverage of up to 480 feet. The return image for each slice is then added to the images taken immediately before and after to build an incredible view of the lake bottom. You can then magnify the detail of the image with the zoom feature or mark the GPS location of promising cover or structure directly on the screen. Side Imaging's high-frequency beams reveal structure, cover, and contour changes with crystal clarity. The images are so real you might think it’s a camera, but it’s not, so it doesn’t matter how murky the water is.  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. 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.
