I have a question about image clarity. When I am looking at my side imaging I can tell that something is there (rock, fish crib, etc) but the image is not very defined. I see images and videos of very clear precise images online but mine is not like that. What would be my first step in clearing things up? Clear water and set to 100’ both sides. I am guessing transducer placement but just not sure ? . Any tips would be great.
