Bottom View; Zoom Width; Khz Sensitivity - Humminbird HELIX 5 SONAR Operation Manual

Bottom View selects the method used to represent bottom and structure on the display.
• Structure ID represents weak returns in blue and strong returns in red. If the Sonar Colors
palette is changed, the Structure ID will display the strongest return as specified by the
palette.
• WhiteLine highlights the strongest sonar returns in white, resulting in a distinctive outline.
This has the benefit of clearly defining the bottom on the display.
See What's on the Sonar Display: Sonar Colors and Bottom View for more information.
Zoom Width adjusts the width of the zoomed view on the Sonar Zoom View, which is on the left
side of the display. See Views: Sonar Zoom View for more information.
83 kHz Sensitivity changes the sensitivity of the 83 kHz beam. Increasing the 83 kHz Sensitivity
will display additional weak returns, and decreasing the 83 kHz Sensitivity will display fewer
weak returns.
NOTE: 83 kHz Sensitivity is particularly useful for adjusting the sensitivity of the 83 kHz sonar returns in
the 200/83kHz Split Sonar View. The 83 kHz sensitivity can be adjusted without affecting the sensitivity
of the 200 kHz returns shown in the 200 kHz sonar window.
455 kHz Sensitivity adjusts the sensitivity of the 455 kHz beam. Increase the sensitivity to display
additional weak returns and decrease the sensitivity to display fewer weak returns.
