I Bubble...a really cool idea!

For all you scuba divers out there. What a neat idea. I wish I had this when I was an active diver!

The visibility was always so poor off of San Diego, I'm not sure how much you'd get. But in clear water it would be well worth it.

pretty much an underwater drone, great idea. i like the thing about throwing it in the water before you go in so
you know what to expect.
