The abrupt changes in the "bright to dark" sections of scrolling data could be the unit adjusting the "Auto Gain" feature ...

If that is true (and there is no TM interference when stepping on the TM) = then the cloudy looking stuff would most likely be thermocline or a plankton bloom ...

Test on a different day or different lake (or part of the lake) ...

If it continues ...post back with more pix ...
