Side Imaging

It’s all in the details. Gain a 180 degree side-to-side perspective on the world below the surface with remarkable Humminbird Side Imaging. 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.

Down Imaging (DI)

Sometimes, to catch fish, not only do you have to think like one, you've got to see like one. Get a fish-eye’s view of what’s happening below your boat with Humminbird Down Imaging. 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 Sonar

Building on their legacy of sonar innovation, Humminbird's exclusive SwitchFire Sonar puts anglers in complete command of how their sonar returns appear. With two unique display modes, 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. Dynamic SwitchFire Sonar shows you baitfish, thermoclines and other dead giveaways of where fish are hiding.

DualBeam PLUS Sonar

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.
