Expanding Recreational Diving

This underwater system by designer Emil Orman aims to make scuba diving a safe & tangible reality for those who suffer from paraplegia. The concept was developed by working hand-in-hand with disabled divers, conducting full-scale diving exhibitions, & carrying out mock-up tests. Buoyancy and body trim can be adjusted via the chest mounted control to assist the user into a horizontal, vertical, or angular position, increasing the freedom of movement & enhancing the overall experience.

    how about adding an electronic hydrojet module?

  • engineering_thoughts says:

    I kinda like the concept of mounting the tank to the BC (buoyancy compensator) – it needs a bit more refinement for practical reasons though.

    That said – the BC, as shown, has no volume in the front – that’s a good way to kill yourself after a dive when you’re forced to be face down in the water. <– this is why life vests have the bulk of their flotation in the front – to bias your body to lie towards your back, face up.

    I was about to say something about scuba divers not using their arms for propulsion

      I have over 300 dives on a back inflated bc with no problems yet…only difference is, they have adjustable buoyancy on their thighs. Push the air out and, presto, you are flossing upright again. That said, it shouldn’t matter because a competent diver brings back up gas or a buddy or both. Even padi (sorry as they are on most curriculum) teaches you a bc is NOT a life vest.

  • superman says:

    somebody should read the initial text again…paraplegia… arm arms for propulsion… bigger picture… do the math.

  • Seamus Dubh says:

    While that is an issue, buoyancy compensator that sit on the back around the tank do exist in current and past diving equipment. I’ve used one myself, but they are more commonly used by Tech Divers.


  • Warren says:

    This appears to be a solution to a problem that doesn’t exist? Why would any diver want an air bladder on their legs so that they were floating upside down. Given that when you’re in the water you’re weightless current BC devices would work fine. If a diver is a paraplegic last time I checked you can buy swim fins for your hands.

    Good design should solve a problem that exists not make something more complicated.

    Test this off FL, PR, Hawaii, Pacific Mexico, Australia, NZ, Brazil, Bora Bora, Nice to expand the seas for ALL comers to explore.

  • i’m not an expert, but i’ve done some scuba diving. to keep your body level while diving (unless under forward propulsion) you need to tension your whole body, otherwise your legs will turn into a vertical position (they don’t just float), thus moving the whole diver into a vertical positon. It’s not much of an effort but still something a paraplegic mostly likely won’t be able to perform.

  • last comment was referring to warren’s remark about the air bladder on the legs.

  • TJ says:

    When you scuba dive, you aren’t supposed to use your arms as propulsion, it tires you out and out use oxygen quicker so you cant stay down as long..

  • In accordance with research, 8% of a nation’s populace is suffering from
    it. The Dupli-Color TELEVISION video is inspirational.

    It may be a dangerous and very real threat to your health.

  • Good blog you’ve got here.. It’s hard to find good quality writing like yours nowadays.
    I truly appreciate individuals like you! Take care!!
