So.. 2-1/2 years ago when our pool was built, we asked the builder for two bubblers on the Baja shelf. He did give us what we wanted, kinda... but I felt they never really looked good. The problem, all that was supplied was two 1-1/2" fpt threaded returns that were flush in the baja shelf. Because these outlets were so big, the water would only rise about 1 to 2 inches above the surface. For the past few years I looked for a return nozzle that would fit flush into the threaded return, so people wouldn't trip on them when walking on the shelf, but surprisingly their isn't much out there.
I forgot to mention, my baja shelf is about 12" deep, so these nozzle are now pushing through 12 inches of water then 6 to 8 inches above the water.
Finally, I found some bubbler nozzles from a company called Custom Molded Products, that fit all my requirements. Grey in color, 1-1/2" threaded and fit flush with the surface.
Here's a video of them in action.

Hopefully this will help someone in a similar situation.
