What is the difference? Helmet diving is described as wearing a large helmet like in 20,000 leagues under the sea, and B.O.B is desribed as a "breathing observation bubble" on an "underwater motor scooter." What in the world are they talking about?!? (Princess eastern caribbean cruise).
Helmet diving is pretty much exactly as you described it. Helmet on your head encloses
you and you breath and walk around on the bottom, air coming via hose from above.
The BOB thing I saw done in Cozumel (they call it BOND). Think James Bond , Thunderball. Underwater moped looking thing with electric power . You are enclosed in a bubble type helmet and "drive" around at one or two MPH . In Cozumel they had a scuba diver swim nearby . They were doing it two "scooters" at a time.
Helmet diving works fine in a controlled environment where you can walk along the bottom standing upright. Just don't bend over. Hope the pump doesn't stop. St Johns has an underwater nature trail that suits snorkelers. Not sure where they do the helmet diving. If you aren't used to being underwater, it sounds like a fairly safe, novel way to do it.

Great pictures! I'm definitely thinking of trying this bob thing too! A quick question. How many people are on this excursion, how long do you have to play with the bob (5 min, 30 min, etc), and how deep or far out in the ocean are you? (i'm kinda scared of deep water like some people are afraid of heights.) thanks.
You actually get to go in the Bob's for about 25 minutes, althought I will say the times does fly, you almost can't believe the time is over. They only take 4-6 at a time, every two bobs has 1 diver to help you. You are only down about 15 feet and I never felt that closed in feeling at all. Hope you do try it out. The time you wait for your group you can either just hang out on the boat or go snorkeling. We were told that they are always booked, so definitely pre-book it.
Just be sure to purchase an underwater camera before you leave home, the divers will take pics of you both for you. If you don't have one, they will of course sell you one for a nice price :-)
