Maximise your angling experience with the Humminbird HELIX 5 SI GPS fishfinder GPS system.

The HELIX 5 SI GPS features
a brilliant 800H x 480V, 5" 256 colour display with backlight. Side Imaging/Down Imaging and DualBeam PLUS sonar with 4000 watts PTP power output, Precision Internal GPS Chartplotting with built-in UniMap cartography with a micro SD card slot for optional maps or for saving waypoints.

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 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.

SwitchFire Sonar

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.

Micro SD Card Reader

Use for advanced cartography or to save screenshots, sonar recordings and waypoints or to update your units software.


The unit comes with a free chart download , so when you receive the unit you choose the area that you require
