Your DI pics of those fish are great I'm still trying to understand what I'm seeing on the SS also.
Does the side image beam go out at 90deg. angle or at a lesser degree?

Doug does a good job explaining side scan in this video. Doesn't matter what brand, the concept is the same.

The center "Main Axis" of each SI sound pulse is emitting at 30° from horizontal....the sound pulse is strongest at this "Main Axis" ...and then the sound radiates out and away from the xducer in an "ever-decreasing" sound strength....
Below is the beam form of the right SI sound pulse....mirror this with the left SI sound pulse...(and remember...the SI sound pulse is a thin slice...so the beam form shape below is only a couple inches thick front to back....with each single ping)....
