83 kHz Sensitivity
(Advanced)
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. The 83 kHz Sensitivity menu
option is available when User Mode is set to Advanced (see Main Menu: User
Mode).
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 83kHz sensitivity can
be adjusted without affecting the sensitivity of the 200 kHz returns shown in the
200 kHz sonar window.
To set the 83 kHz Sensitivity:
1. Make sure the User Mode is set to Advanced, then highlight 83 kHz
Sensitivity on the Sonar main menu.
2. Press the LEFT or RIGHT Cursor keys to set the 83 kHz Sensitivity. (-10
to +10, Default = 0)
