So I use a regular Echomap 93sv to Sidescan with. Once you see a likely prospect of trees or structure using a Fishfinder on the bow, preferably with a GPS to mark it with when on top but not necessary. Set the Fish Finder to 2D (Color) with a combination output like 83/200 or 50/200 whatever your fish Finder combination settings are possible, also turn on the "A Scope" or I forget what Humminbird call it but the real time sonar RTS window. Troll using your trolling motor right on top of the Structure till you see it in the A-Scope or RTS window. Vertical fish right down the side of your trolling motor. You will be on top of the Structure as long as you keep it in the A-Scope or RTS window. I can't teach presentation over the internet but my description of presentation above fills my coolers every trip. I do not post all the fish I catch as then I will look like Ketchn. Read what he posts as there is Gold in his ramblings about presentation, technique, etc.
BTW The PS22TR Panoptix Transducer was designed to work with a regular 92sv-95sv standard definition. No Echomap Plus or Ultra is needed.
