... I'm not sure if the above picture has the proper settings, I never have that much clutter on the bottom over open water.
Re: the pic-- it's possible you're right, I'd thought that was a thermocline based on the horizontally localized nature of the clutter and fish sitting above it, but it's possible it was some sort of stuff in the water or a setting. I actually took the pic to try and get feedback on what that stuff was, and the unanimous decision on another forum was a thermocline, but we all know the internet isn't gospel....I've seen that type of clutter appear out of nowhere on a clear screen lifting off the bottom--I've been told that's phytoplankton. Ive also seen a "column" of clutter like that in one very small area, and a number of times its been in shallow water where I was able to look and see what it was....nothing I could see--i believe these were colder water springs and the sonar picked up the plume of cold water in a similar fashion to the bottom layer in the picture. If it was a setting wouldn't it indicate something different about the water at that depth, as its certainly not running put of power at 35'?? Either way, it's a bit irrelevant, the point being that if we're wondering whether we're looking at a thermocline, phytoplankton, or some setting is picking up stratified water...its plenty sensitive for me! Learning how to interpret what I'm seeing is half of learning how to read these things, so if anyone has a different read on it by all means let me know! Hope this doesn't take things off-topic.
