I was out fishing last week and started thinking there was a mass party going on in 18-20 ft of water for a good 1/4 mile stretch based on what I was seeing from my sonar. I drifted this stretch a few times throwing out some small plastics and couldn’t get any action. I switched over to 77khz from 200khz and the picture dramatically changes.
Is the 200khz just picking up more junk suspended in the water? A lot of the returns look like small fish to me. There were a ton of leaves floating around from some strong wind gusts the two days prior. I know in shallower water the 200khz signal will give me a lot more detail and target separation than the 77khz but the difference seemed significant.
