Bottom View; Zoom Width (Sonar Zoom View Only); 83 Khz Sensitivity (Advanced, Dualbeam Plus Sonar Only); Depth Lines (Advanced) - Humminbird HELIX 5 SI GPS 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.
Depth Lines divide the display into four equal sections which are separated by three horizontal
depth lines. The depth of each line is displayed along the depth scale. You can turn Depth Lines
On or Off.
