Humminbird GPS Helix 7x SI

The Humminbird GPS Helix 7x SI is a perfect sonar for every fisherman. It stays true to the Humminbird´s "SIMPLY. CLEARLY. BETTER." slogan and lets you have the perfect fishing experience. Thanks to the unique modes of operation, you can adjust the setting of the sonar based of the situation in the water.  The revolutionary Side Imaging, Down Imaging and SwitchFire Sonar technology make it a valuable tool for searching fish. DIt can be mounted directly into the dashboard or a location of your choosing.

Side Imaging

Gain a 180 degree side-to-side perspective on the world below the surface with Humminbird Side Imaging technology. Three razor thin beams take the ideal “sonar snapshot” of the area to the left, right and the bottom of your location. Unlike the conical beam (directed to the bottom), the Side Imaging´s beams are very narrow horizontally and wide vertically. They reveal structure, cover, and contour changes with crystal clarity. The images are so real even in murky water that you might think you are looking at a camera shot. 

Down Imaging

The detailed images of Down Imaging technology are created with high-frequency sound waves emitted in ultra-thin slices. The sonar returns from these waves produce a "snapshot" of what's below your boat. A perfect updated image is continuously being displayed on the screen from right to left. Watch fish, reefs, timber, brush, bridge pilings, or rocks with stunning detail as you patrol the water.


The fishfinder has a built-in GPS receiver and UniMaps. Thanks to a memory card you can upload additional maps to the device or work with your own maps and navigation data. The memory card also allows you to upgrade your operating system, record images and videos underwater, track your route and collect navigation data.
