Zoom Width
(Advanced)
Settings: Narrow, Medium, Wide; Default = Wide
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
(Advanced)
Settings: -10 to +10, Default = 0
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 200/83 kHz 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.
