I went to this lake to scan a bridge someone told me about. The water was extremely muddy after a major rain event so on the way to the location, I had to use 455 kHz for Side Imaging to get some range since the MEGA frequency is so sensitive to particles and temp changes. When I got there and passed over the bridge, I knew some settings had to be changed to get any detail in those conditions. This is the first pass

So to get the sharpest images takes the MEGA frequency which is too sensitive for those conditions without some filtering. I made a few passes doing some adjustments and was able to get this:

The current and wind made it difficult to stay in position for 360 so this is the best I could get with that:
