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.
