This video will show you how to adjust the 2D Sonar Contrast on your Humminbird HELIX via the shortcut menu on the sonar view.

2D Sonar Contrast allows you to control the difference in brightness between bright and dark objects. It does not control the amount of detail displayed, that would be Sensitivity. Increase contrast to make brighter objects brighter and darker objects, darker.

While on a 2D sonar view, simply press the Menu button on your HELIX to pull up the shortcut.

• 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.
