Bottom Discrimination

G'day,
I've pulled some nice fish off the spots below, however I found it hard to discriminate the bottom type.
I know the general rules of the thicker the harder the bottom, the more tails the rougher etc, but if anyone could please point me into specifics of these shots that would be great.
In addition I was wondering who uses the bottom lock side to try and differentiate coarl types etc and what colours they look for.
At the moment I'm thinking the little bit of yellow with green tips above the bottom may indicate plate coral or a hard slate bottom.
I'd love to hear your opinions, or any advice.
Cheers

Agreed
If you want a second opinion on the ground, just let me know where and I'll happily investigate with a jig or bait what is on it. Hahaha

Bit hard to see
With your depth reading so big it covers everything

Just looks like
Hard flat coral . Prob small soft brain corals and soft fan corals on top with small ledges. 1 pick looks like has them small cave fish( bulls eyes ?) unsure what there called. That's how I would read it. 90 percent of my Dhue ground is flat thick coral . Similar to your pics . Hard to tell weather looked chopy by the look of right side of screen. Good fish if it holds doesn't really mater what it is. Top feed

I see you are using a big BL scale
I used BL extensively when I was crayfishing, in the deeper water. It was extremely useful for picking the good bottom from the crap--99% of deepwater out from Kalbarri is crap, hardly catch a cray on it. We would look for the flares, and colours coming up from the bottom, BUT we were using a much shorter range, usually 2 fathoms ( under 4 metres.), or even half that. Not looking for fish. Have you tried going to a smaller scale on the BL? You appear to be using zoom or Shift to look for the actual fish on the other half of the screen, which is the way to go for demersals. Then just use the BL , on the smaller scale, for bottom discrimination? The changes will be far more obvious.
