The new (to the USA) Divator MkII Divelite tank system is approved for use in the USA. Although it has been used in Europe for quite some time we will be able to get it here now. I dove the system back in the 1970's when it had steel tanks and it was very nice in that version. I look forward to seeing and / or owning one in the near future. Even when filled to the US standard 3300 psi it will be about 108 cubic feet. We are so behind in diving technology here it is sad.
