Because in 100° water, they were cooked to death and they have fallen to the bottom and sunk into the silt?
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
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 .
Sorry about the erroneous temp reading ...Quote:

LOWPRO HIT IT,FISH ARE FARTHER AWAY THAN BOTTOM READING,I SEE IT A LOT WHEN I AM ON DI
Don't have a clue. It could be an underground river system that allows fish to escape me when I am fishing That's why I don't catch fish all the time. They are in the fish subway system.
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.Quote:

What Evers causing it......please make it stop��
Thermoclines can definitely cause some images to seem not what they appear ...Quote:

I took the bottom left corner of the image and enlarged it so that I could paint stuff on the actual image ...

We know the unit should be able to correctly calculate depth (aka distance) to a target because the equation the unit uses to calculate this distance to a target is constant (except for water salinity) ...
So the bottom depth calculation (25.3') and the distance to "Fish ID target" calculations (24') should be correct ...
So it seems my HB 1197 with software version 6.310 "paints" the Fish ID icon below the actual target echo (strong color blotch) ...
What we should learn from this is that if a certain software version does indeed include a "depth label" to a Fish ID icon ... We should trust the "depth label" more than where the Fish ID icon is "painted" in the water column ...
----------
What I can't figure out is how to turn on "depth labels" to Fish ID icons in my Onix to know how far away fish targets are from the Onix xducer ...
