Good news and bad news....
My high speed readings with the new transducer are awesome!! And I'm getting both side views.
The bad news? I screwed up my HDSi transducer.
I tried to squeeze it in just under the motor mount and just above the bilge plug where it would have a good view of both sides and would be somewhat protected. My boat is too low on the trailer so I can't trim the motor all the way down unless it's in the water, so I made some measurements to place the transducer so the cavitation plates on the motor wouldn't hit it. It needed to fit nicely in between both plates - which it did - but I didn't take the cable into consideration. The upper plate hit the rubber boot on the transducer cable and tore it up. The transducer was still working when I pulled the boat out so, hopefully, I can goop it up with some sealant and keep water out of the transducer. Expecting failure, I went ahead and ordered a new one today. $167 at Beach audio by the way...
Here is the new transducer location..

Here is the torn up transducer...

And here is the awesome new dual beam addon. You can see where the HDSi was located which didn't give me good left side readings and worked badly at high speeds for the 2D downlooking readings.
