Wow, I'd like to have one of these. It makes me feel like aquaman. Lol. I've done intro diving and its a different world underwater. Having this type.of machine can make it easier for divers to traverse the water. I'm just concerned if its safe to go deep with this one as I know divers need to "equalize" not sure of the term on certain sea levels as they dive down because of the change in water pressure. Nice hunt.
