This mini tank gives about 10 minutes of time under water....

I'm considering replacing my large and heavy traditional SCUBA gear with this very small, light and re chargeable (with a hand pump) tank. Has anyone used it, have any comments and know where I can buy it in Australia?

From their FAQ -
At 1atm and 3,000psi the Scorkl holds the equivalent of roughly 60 breaths (assuming breath size of 1.6L). An inhale/exhale cycle of 10/min (1 every 6 seconds) allows for ~6min underwater at 1atm. A slower cycle of 6/min (1 every 10 seconds) allows for ~10min underwater. These cycle times are slower than average but very achievable by an experienced and relaxed diver looking to minimise air consumptionSpearfishing enthusiasts as well as freedivers will be able to use the Scorkl intermittently (i.e. a breath only when called for) during a whole dive trip that may last for 1hr+

At 3,000psi the Scorkl holds about 60 breaths at 1atm. It takes around ten pumps per breath to fill the Scorkl (600 pumps). It gets harder to pump as the pressure in the tank increases but it is manageable for an adultA steady pumping rhythm of 50/min (<1/sec) fills the tank in 12min. Most people will want to rest intermittently though which also allows the pump to cool down

Maybe 5min under water if you are lucky and 12 min to refill, if you are fit. I would rather hold my breath!

Thanks Valo. I'm aware of that link and am concerned about two things: (1) the quoted delivery of "October 2017" which of course is one year ago, and (2) all the comments where people have sent their money but never received the product nor an explanation.
This is why I'm asking about an Australian supplier of the product (which I suspect does not exist).

I carry a 12v Sea Breathe hooker rig on board which is great for cleaning the bottom and any maintenance. I have 25mts of hose which means I can get down about 15mts to unfoul an anchor if need be. I would not recommend any one to use one of these over 2mts down unless you are a certified diver which I am.

Interesting link. Thanks for that. 5 minutes is not long and that's breathing normally. I find when I use my hookah I over breath at first, especially in cold water. I would soon empty one of those bottles.

One other thing, in Australia your scuba bottle has to be pressure tested every year, yes, EVERY year and this thing with pressures of 3000 psi would fall under the same regulations, so there is that to consider as well before deciding if it's good for you.
