In such situations when you see too much clutter on the screen, increasing the
Noise Filter will play an effect. The larger the value is, the more unexpected sonar
returns will not be displayed.
If the Noise Filter is increased too high, most sonar returns (which maybe fish) will
not be displayed
In situation while water is clear, try decreasing the Noise Filter, however in
situation while water is turbid, try increasing the Noise Filter will be helpful.
When the water is deep enough, the high value setting may greatly affect or even
hinder your Fish finder’s performance to find the bottom. So, in deep water,
decreasing the Noise Filter value will be helpful.
Note
: in some situations while you have big trouble with noise, try finding and
fixing the interference source, rather than operating your Fish finder with a very
high Noise Filter value.

clearly visible on the display;
