Because in 100° water, they were cooked to death and they have fallen to the bottom and sunk into the silt?

Sorry about the erroneous temp reading ...

I was using the LSS 2 on my 1197 when I took that screenshot ...
(Lowrance temp probe doesn't read correctly when connected to my HB) ...

The thermocline is causing a false reading on the bottom . The depth is shown at 25.3 feet the fish are marked above that depth. The bottom is also shown above that depth

Thermoclines can definitely cause some images to seem not what they appear ...

I would surmise in this example ...the bottom is "painted" at the same vertical distance from the xducer in both the 83kHz window and the 200kHz window ...and the estimated vertical distance from us 22.5' depth line would indicate the bottom is "painted" correctly ...

On the side of the sonar cone. So farther away from transducer than the bottom.

Because that is one great sonar those are mud turtles.

Sonar only tells time right? Bottom depth is being read more in the center of the cone, and the fish are in the very outside edge of the cone. Thus meaning the fish are further away from the transducer than the point at which the (bottom being read is). So this is how it looks when its laid out on a screen???

I vote with LowePro. That or the HB software is now displaying the fish symbol below the echo instead of above .

I'll go with this one ...... Looking at the depth number displayed with the fish ID, the numbers are 22,23, and 24 ..... Which would not be below the bottome reading.
