This device boasts a 7-inch color TFT display, which provides clear and vibrant images, making it easy to view the underwater terrain. Its MEGA Down Imaging feature offers exceptional clarity, revealing details up to 125 feet below, which is significantly more precise than standard down imaging sonar.

The Dual Spectrum CHIRP sonar enhances your fishing experience by providing highly-detailed fish arches and clear views of structures on the bottom, giving you two modes to choose from – Wide for maximum coverage, and Narrow for fine details. The internal GPS and Humminbird Basemap are very useful, as they provide comprehensive coastal and inland waterway charts, covering over 10,000 lakes and coastal areas in the continental U.S. This feature ensures you can navigate confidently, identifying various points of interest and hazards.

Furthermore, the AutoChart Live feature allows you to create real-time maps of your favorite fishing spots, which is great for anglers who like to keep detailed records of their fishing locations. One of the drawbacks is that the device is battery powered, which may require additional planning for extended trips to ensure you have enough power. Another consideration is that while the screen size is decent, some users may prefer a larger display for even easier readability. Additionally, the unit's price point may be on the higher side for some buyers, but it does offer a comprehensive set of features that justify the cost. The Humminbird Helix 7 is a well-rounded fish finder that should satisfy both casual and serious anglers looking to improve their fishing efficiency on a pontoon boat.
