Hi Alex and all.
I have seen something similar on a StreamPro measurement as well. Overestimation of speed in the 5th bin. Depth around 1-1.3 meters, down to 2 meters. ARC boat. Clear water in the outlet of a lake. I don’t know what this is. If it was some double reflection phenomena the erroneous velocity should have followed the shape of the river bed.
I have used this instrument many times and this is the only time I have seen this happen.
Any ideas?

PS: I know it was too shallow for the ARC boat to be ideal here. DS
