Equipped with the latest generation of MEGA Side + Imaging technology, the HELIX 15x CHIRP MEGA SI + GPS G4N allows you to see the underwater world like never before, with a crystal clear view of 200 feet on either side of your boat. Now you will see 20% more information on the sonar screen than with previous technology.
The fishfinder is equipped with three new scanning technologies Mega Side + Imaging, Mega Down + Imaging and Dual Spectrum CHIRP. Powered by a new, patented Low Q CHIRP sensor, Dual Spectrum technology offers two search methods: wide mode for maximum coverage and narrow mode for maximum detail. Mega Side + Imaging technology, with a scan rate of 1200 kHz, offers incredible clarity for side scans up to 200 feet. Mega Down + Imaging technology, with a scan rate of 1200 kHz, offers unprecedented clarity of the bottom structures and fish under your boat. Humminbird CHIRP is designed to meet the specific challenge of showing you fish and underwater structures with better quality than other sonar technologies.

Dual Spectrum CHIRP: 150-220 kHz, 180-240 kHz, 140-200 kHz
Mega Side Imaging + 1200 kHz: 1075-1150 kHz
Mega Down Imaging + 1200 kHz: 1075-1150 kHz
Down Imaging 800 kHz: (800-860 kHz)
Side Imaging 800 kHz: (780-840 kHz)
Down Imaging 455 kHz: 440-500 kHz
Side Imaging 455 kHz: 440-500 kHz
Create detailed maps of your favorite fishing spots in real time with the patented Humminbird® AutoChart® Live technology, a free feature now available for the HELIX 15 CHIRP MEGA SI + GPS G4N series fishfinders. No need to upload your data to view. With the advent of AutoChart® Live technology, the future of digital mapping has arrived. The sounder has internal memory for storing recorded AutoChart® Live information. High-speed Ethernet allows you to create a powerful professional fishing system that allows you to connect multiple fish finders or Minn Kota i-Pilot Link electric motors, 360 Imaging transducer, and CHIRP Radar. Built-in Bluetooth allows you to enable features such as over-the-air software updates from the Humminbird FishSmart app and displaying mobile notifications on your Humminbird. Plus, you can control your most frequently used functions with an optional Bluetooth remote control (RC2).
HELIX 15x CHIRP MEGA SI + GPS G4N has a built-in GPS receiver and a pre-installed UniMap mapping package. The microSD card slot allows you to install Navionics +, Navionics + Small, Navionics Platinum, AutoChart navigation charts, as well as record sonar information for further viewing and study. The navigation part of the echo sounder allows you to save points, routes and traversed tracks in the echo sounder memory. With the free Humminbird PC software, you can save and edit your route, and create your own routes. The echo sounder is equipped with the Fish ID + system, has a display of water temperature, allows you to take a screenshot and freeze the image on the screen.
