Sounder settings and bottom discrimination

Hi, I know how to use my sounder to find/see fish but what I really want to know is how do you tell the difference in different bottom. I know harder bottom will be thicker red and all that but how do you know what bottom is good for coral or what does mud look like? I’m more interested in setting cray pots in a bit deeper water about 20 - 30 fathoms. Also what settings do you use for each bottom? Sorry for all the questions, if you have photos that would be awesome.
