bait school on the bottom, nothing real big and solid in there, perhaps turn your sesitivity down and drift past again, bottom looks sandy too i may be wrong, always helpt to read your sounder manual

Bruce is exactly right- a mate has one of those sounders on his tinny- you need to see more rigid, larger colour "smudges" to indicate large mass (ie fish). He also right about the sensitivity- it will make a big differance and the bait thats holding near the bottom will look a lot smaller and easier to identify

my view is close to Bruce ,  theres small fish or bait fish huggig he bottom flat reef or coral because the bottom red line is reasonably thick, the school or bait fish may only be smallish fish that are red and yellow which are hugging the bottom or just of , this is where the yellow line seperates around the outside of the group, also in the last picture you have what looks like a anchor or your rig going down to the bottom. aslo at the 5 /6 mt mark theres other fish , i would zoom out as your on 2x zoom go back to 1 x and check what else is happening closer to the surface.   unfortunately you will see this often an hope its a good school of decent fish, you would need to maybe work a SP through it to see if theres something that could be stirred up or some thing bigger hanging around the bait fish . in this depth i would want to see the so called arches which would indicate there some thing bigger chasing the bait fish 

So turn the gain down you reckon & no zoom. I'll try that on the next outing.

Thanks guys.

just to compare what you are seeing mate thats all, my sounder lights up like that on certian days and you think you've found the motherload but nothing.......

To help identify what your sounder is showing you I recommend getting a book understanding your sounder by RIck Huckstep - easy to understand and gives you numerous examples (only around $15).  I disagree with the turning your gain or sensitivity down - all this is going to do is show you less information.  Sensitivity should be as high as you can go and only turned down when you are getting to much clutter on the screen which you are not (given you have plenty of blue showing).  I would also turn your chart or scroll speed up to high as this will show you more (turning it down shows the same amount of info on less of the screen - compressed you might say and means you have less pixels explaining what's down there.  As for big fish be aware sometimes these will only show up as a full or partial arch when it is moving through the "cone" of your transducer from one side to the other - bear in mind a large fish can show as one or two pixels (dots) if it just flicks through the edge of the transducer signal. 

That being said the signal does appear to be baitfish of some sort

Hope that helps
