Noise Filter
(Advanced)
Noise Filter
adjusts the sonar Noise Filter to limit interference on the display
from sources such as your boat engine, turbulence, or other sonar devices. The
Noise Filter menu option is available when User Mode is set to Advanced (see
Main Menu: User Mode
).
NOTE:
The Off setting removes all filtering. Low, Medium, and High1, High2, High3
settings add progressive filtering of the sonar returns. High1, High2, and High3 are
useful when there is excessive trolling motor noise, but in some deep water situations,
the High settings may actually hinder your unit’s ability to find the bottom.
To change the Noise Filter setting:
1. Make sure the User Mode is set to Advanced, then highlight Noise
Filter on the Sonar main menu.
2. Press the LEFT or RIGHT Cursor keys to change the Noise Filter setting.
(Off, Low, Medium, High1, High2, High3, Default = Low)
Max Depth
(Advanced)
Max Depth
controls the maximum depth of operation. When Max Depth is set
to Auto, the Fishing System will acquire bottom readings as needed (within the
capacity of the unit). When Max Depth is set to match your fishing maximum
depth, your Fishing System will not attempt to acquire sonar data below that
depth, so more detail will be shown on the screen.
NOTE:
If the bottom is deeper than the Max Depth setting, the digital depth readout
will flash, indicating that the Fishing System cannot locate the bottom.
NOTE:
The Max Depth menu option is available when User Mode is set to Advanced
(see
Main Menu: User Mode
).
To change the Max Depth setting:
1. Make sure the User Mode is set to Advanced, then highlight Max
Depth on the Sonar main menu.
2. Press the LEFT or RIGHT Cursor keys to change the Max Depth setting.
