This video shows you how to adjust the sensitivity of your medium and high-frequency CHIRP sonar range on your Humminbird HELIX via the Sonar Menu.

This allows you to adjust your sensitivity without compromising the sensitivity of your high-frequency CHIRP sonar range. This is most useful when both 2D frequencies are displayed at the same time.

• NOTE: Some menu items or features may have been changed, been moved, or added since the filming of this video. This video was filmed on a HELIX G2.
