In the first pic u are seeing 1 of 2 things, either the start of a thermocline and I say that because the top 8 or less feet show clear, OR u are seeing an algae bloom if the water was stained. Underneath those longer more solid marks are fish. B&W sonar is hard to interpret because u dont see the strength of the return as u do in a color sonar. Go thru the menus and see if you have a sensitivity setting and turn it down a little, til u get some of that fuzz cleared up. I have 2 of the best combo sonars and there is NO simple setting that works great, it can work good if you set it w a compromise and leave it be. If you want the best out of any unit u always have to adjust it based on water depth, bottom type, and body of water u r fishing. Even a cheap POS can do wonders if you learn to adjust it and it beats having nothing, play with it some and u will be amazed what u figure out. And its always easier on softer/mud bottoms, u get bounce back and interference more when over rock/gravel bottoms. Having 2 sonars both running can give u fuzz like that esp when they are the same brand and on the same frequency
