Side Imaging Sonar
Side Imaging Sonar -- Gain a 180 degree side to side perspective on the world below the surface.
For greater on-water flexibility, 360 Imaging lets you choose from five beam speed settings. Lower beam speeds lead to higher image quality but lower refresh rates. Conversely, higher beam speeds result in lower image quality but higher refresh rates. With five options, you can find the ideal setting for your boat speed, water conditions, and need for detail.
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 Sonar
Down Imaging Sonar -- Get a fish-eye's view of what's happening below your boat. Incredible images are created with High-frequency sound waves
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. 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 Sonar -- Take command of how your sonar returns appear with our Clear and Max Modes.
Building on our legacy of sonar innovation, exclusive Humminbird SwitchFire 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. SwitchFire adds a whole new dimension to 2D fish-finding. It's one more reason Humminbird is simply, clearly, better.
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.
GPS antenna built into the head unit
Get unparalleled GPS technology out of the box. Many Humminbird fishfinders have our powerful Precision GPS/WAAS receiver built right in and provides fast position fixes accurate within 2.5 meters.
For those models without it, there are several options:
Add the Humminbird Precision GPS/WAAS receiver for permanent GPS capability on your boat.
Use Humminbird?s adapter and the NMEA output on your own handheld GPS unit, or use Humminbird?s InterLink to allow two fishfinders to access one GPS receiver.
