Rnvinc I liked Slabbacks answer of the pea gravel, do you know what the bottom actually was?
Thanks I learned something new!
Good questions Kosmo, looking forward to the DI answer.

I would say "somewhat"...
In the image below (also from Doug) ...we can definately see in the DI image the same "brightness" of the harder bottom that is seen in the SI image ...
1 point to remember in the above image is this is "DI from SI" ...which is the same data - just rearranged in the DI image ...

Thanks rnvinc, I don't use 2d much, maybe 1% of the time. I liked the pea gravel, because it had the thin red line on the top of bottom. I really appreciate the quiz posts. Sometimes I can't ask the question, because I don't even know what I don't know!!
That's as clear as a silt bottom! LOL

I would have expected the thin red line to change to a lighter color at the transition ( B1 ) Learn something new everyday.............

I believe you can tell the difference between hard and soft bottoms on DI. I know you can see when it changes.
rnvinc here are two shots for you. This first one I know to have peegravel due to using a jigging spoon and coming up with small gravel in the hooks when I let it hit the bottom and jerk it back up. Also I use break rotors from a truck as a anchor and have small chunks stuck in the grooves.
In this shot it's a compacted mud flat...the anchor comes up with a cloud of gunk lol. This was the reasoning for the earlier post in reference to the peegravel. I have a lake that is shell rock and should have some shots in 2D in one of these files. When I find one I'll post it as well. The RED line is much thicker in those shots.
I would have thought the red line would have gotten thinner or changed colors as it transitioned from hard to soft bottom. Was this a function of the under lying layer transitioning while to surface layer remained the same?
