Guys
I have a question regarding when to use 50 mhz or 200mhz. I have been using this feature on my furuno 620 . colour erase 10%, Clutter 20%
TVG- Medium and B/L
I know some people use 20% colour erase and 30% clutter?? so which is a general good setting.
What depths do i change from 200 mhz to 50mhz.
