Noise Filter
(Advanced)
Settings: Off, Low, Medium, High1, High2, High3;
Default = Low
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 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.
Max Depth
(Advanced)
Settings: AUTO, 10 to 1000 ft, 3 to 330 m [International
Models only]; Default = AUTO
Max Depth
controls the maximum depth of operation. When Max Depth is set
to Auto, the Fishfinder will acquire bottom readings as needed (within the
capacity of the unit). When Max Depth is set to match your fishing maximum
depth, your Fishfinder 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 Fishfinder cannot locate the bottom.
