I ran the Lowrance GEN2 HDS9 last season, but switching to the new Lowrance ELite Ti7 this season. I used the RAM arm for the StructureScan transducer. Scotty just cam out with a transducer mount that I've switched over to. The RAM unit had a lot of movement and it took a few minutes to get the transducer level every time. With the Scotty unit, I will just have to e drop it down and it should be in the correct position.
Here is the RAM arm.

Here is the New Scotty...I'm still waiting for my new Lowrance Elite Ti7 with the TotalScan transducer to come in.
