Noise Filter
Noise Filter is used to filter the noise from the air or water enviroment to get a clear
sonar image on the screen.
In many situations, your Fishfinder display will be effected by undesired signal which
maybe caused by your boat engine, turbulence, wiring, or other electrical and
mechanical sources. Such undesired signal will produce unwanted mark on the screen,
which may cause a misunderstanding of the underwater condition.
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 hige, 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 Fishfinder’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 Fishfinder with a very high Noise
Filter value.
Note:
there is 9 level and “Auto” option for Noise Filter setting. The setting with
“Auto” or 3~5 level is suitable for most using condition.
