Did you want to take Open Water diving from a PADI authorized instructor? You can dive to 18M. (That’s 60 feet in a real measurement system.)
How about Advanced Open Water, also from PADI? You get 30M – or 100 actual real feet.
What does the advanced class consist of?
For Advanced Open Water Diver, student divers meet performance requirements:
Complete five Adventure Dives including Deep and Underwater Navigation.
Complete the five Knowledge Reviews for the Completed Adventure Dives
You want a TriMix certification? You’ll learn how to used mixed gas to go to 165 feet. (That’s 50M in a fake French measurement system.) What is are the requirements for TriMix what is are the requirements for TriMix certification:
Certified as a PADI Rescue Diver or have a qualifying Certification in a rescue and accident Management
Minimum age: 18 years
Certified as a DSAT Tec Deep Diver
Have a minimum of 150 logged dives
You want to go really really really deep? Not currently a PADI Certification but Try breathing liquid air. Well, don’t. But think about it. If you use
perfluorocarbon (PFC), a synthetic liquid fluorinated hydrocarbon-clear, odorless, chemically and biologically inert, with a low surface tension and high O2/CO2 carrying capacity. PFCs can hold as much as three times the oxygen and four times the carbon dioxide as human blood. They also act as very efficient heat exchanges. This makes PFCs ideal for use as a liquid ventilation (LV) medium for medical applications.
I think what really startles me is that someone thought: let’s put that in our lungs. Really, can you imagine breathing in a liquid? Many of the skills you learn in Open Water are organized around making sure that you can manage NOT putting liquid in your “best to keep dry” spaces. So you learn lots of different ways to clear your mask, clear your regulator, etc, etc.
What else can you imagine for the future of SCUBA?
How about helmet-to-helmet communications? That already exists – for both commercial and recreational applications. The trick here is that systems are completely incompatible with each other. So if you have *a* system then you want to make sure all your mates have the same system. OTS makes a system that works well for the recreational Diving. I have one of my Own that I use for underwater weddings and they take a bit to get use to but they work very well.
My favorite SCUBA system is the direct-to-dive teleportation system. I prefer to take at TARDIS whenever possible, but teleporting is nice too. I like that I don’t have to carry my bag or any tanks. (Kidding, that’s not possible. Yet!)
