Hey guys, just got a 106 SV and I'm trying to figure out what's soft and what's hard according to the different color palettes.

I just contacted Garmin to try and find out if they have "hardness guides" showing what's hard and not for their different palettes, but as of now they don't have anything.

Being new to sonar, I really have no idea what's hard and soft according to 2d. Does anybody have any info on this?

Thanks in advance.
