Six years ago we told you about the Australian-designed Scorkl, a mini compressed air tank that allows users to breathe underwater for up to 10 minutes. For easier on-the-spot refills, the 2.0 version can now be ordered with an electric air compressor and a "battery pack."

To recap our previous coverage, the Scorkl itself is a compact air cylinder with an attached regulator and pressure gauge. It's small and light enough that instead of being worn on the diver's back, it simply hangs down from their mouth as they swim.

Users refill the device by hooking it up to either a traditional dive-store air compressor, a conventional full-size pressurized scuba tank, or an optional system-specific hand pump. The Scorkl 2.0 system, which is currently on Kickstarter, offers another alternative – a small electric air compressor.

To utilize it, users just plug the compressor into a regular wall-type outlet, connect it to the Scorkl cylinder that needs refilling, then press a single button to set it going. It can also be powered by a car or boat battery, or by an optional battery pack.

The latter unit doesn't contain a battery of its own, but instead serves as an adapter for one or two third-party 18-volt power tool batteries. It's compatible with Milwaukie, Makita, Bosch and DeWalt batteries, which the user has to supply. There's currently no word on how many refills one or two fully charged batteries will provide.

Of course, safety is always a concern with products like the Scorkl, which allow people to perform potentially dangerous activities without formal training.

Well, as far as decompression sickness (aka the bends) goes, Scorkl inventor David Hallamore tells us that due to the cylinder's limited air capacity, users aren't able to stay deep enough for long enough to be put at any significant risk. There still is another potential danger, however.

"Lung-expansion injuries are a real risk for Scorkl users," he says. "This is where damage to the lungs can occur if a user neglects to breathe continuously, or exhale, during ascent […] All Scorkl users receive this safety information in their user manuals, as well as follow-up emails upon delivery with links to the Safety and How to Use videos. There is also a big sticker right underneath the mouthpiece reminding the user of this risk each time they put the regulator into their mouth."

Assuming everything goes according to plan, a pledge of AUD$1,765 (about US$1,147) will get you a full package that includes a cylinder, compressor and battery pack – the planned retail price is US$1,747. Backers can also buy just one or two of the individual components for lower amounts.

The Scorkl 2.0 system is demonstrated in the video below.

I seem to remember something that would float on the surface and pump air down. If one of these tanks is good for 10 minutes, that's a lot of surfacing and charging

Having just completed the very extensive PADI scuba certification, I think providing the means to dive without training is a very bad idea.
History Nut
Whatever happened to "Spare Air"? That is the unit I bought around 20 years ago when I was SSI certified. I agree with Eggbones that SCUBA without training should be discouaged. The "Spare Air" was marketed more as an emergency back up to your regular gear.

The tank/regulator is just like the SpareAir that has been around for at least 25 years - I have one that is about that old. But selling these to the general public is a very, very bad idea, and someone is going to blow out a lung (serious injury or death) because they had no training. Someone will take this to their swimming hole, a friend will see it, try it out and probably die. I don't think a sticker on the tank is going to educate anyone on the danger these devices present.
PAV
I see a lot of comments about the danger of these compressed air tanks for untrained users. I personally think that if you are told to exhale as you surface then that should be enough. But for those that can't or don't read, well, what are you going to do, you can't protect everybody, some of us have to have fun.

PAV has a point, we can do a lot of very dangerous things without proper training, riding a bike, climbing a mountain/cliff or going out on a Friday/Saturday night out binge

As things go applying the 10m/10l then this product should be fairly safe for most users provided they read the clear instruction breath out as you surface.
Of course there are those who will ignore or forget.

Overall its a great idea, sometimes even qualified and fully kitted divers would love to have a very simple piece of (light) kit to take with them, just in case an opportunity for a short shallow dive occurs.
