A 12K BTU burner and a cast iron skillet will certainly do the job of searing sous vide meat without cooking it any further. You won't get that from the grill side, because there isn't a gas grill made that can generate the heat to do that kind of ultra-fast sear. And honestly, it seems like a waste of time and materials to light up a big pile of charcoal to sear sous vide meat for a minute per side.
You can do the quick sear on your side burner, get the job done fast, and not smoke up your house.
Enjoy your new toy.

Actually Casey, I won't even need a cast iron skillet as the Mega searing burner has its own grate for impressive grill marks.
I've never seen anything like it on another grill and I can hardly wait to use it. Details to come.
