    Image Interpretation Request

    Trying to figure out what was going on yesterday. Just started using the unit at the bow with a HDI transducer. Sonar seemed to look right but my downscan had either artificial or seeing something below. I didn’t really fret it because it was tracking artifact

    Water was stained but not abnormal. Wind was about 10-15 MPH.

    Whats your interpretation?

    looks like a steady pattern like electrical interference.turn off every device what you can then start up one by one to see if any change.

    Thats strange. The only thing that I was really running was the TM which I do believe is causing slight interference. I guess my question is more related to the Downscan and the dots and such. Is that what you are referring too? I get slight flickering on my unit. Not sure what causes it but the unit was just replaced by lowrance.

    Generally: Downscan will start to do "funny things" when the boat is stationary. Downscan (and SideScan) depends on movement to work properly.

    I think what you are seeing on DS is algea. You can see it on 2D as well (the few blue dots) but since the sensitivity of 2D and DS is different, you see more of it on DS then on 2D. I bet that if you turn up sensitivity on 2D a notch or three, you will see lots more blue dots from algea and 2D/DS will start to look more the same.

    I'm hoping it is just cause of dirty water. Wind was blowing so I wouldn't be surprised. I do see slight interference with my TM but nothing that should cause the dots and lines. I'll check it out again later this weekend.
