I saw it at ICAST last week, still in prototype (at least the Elite sonar mount is). It looks like a clean, well-engineered solution. I'm hoping to get my hands on the new Lowrance kayak products soon.
Lowrance reps say the through-scupper mount should work on 95% of the sit-on top kayaks out there. I'm still waiting for a list. It would be nice to know where it doesn't work.
Here's a nice thing. The through-scupper mount works with the odd little lightweight "pencil" transducers for Lowrance DSI (downscan) sonars. Those aren't supposed to work through-hull, so without this new through-scupper mount it's a bit of a hassle to install.
During ICAST I posted three or four photos and brief comment on the Kayak Angler Facebook page. Here's the first one. If you're interested you can click to the rest:
