Does not recommend this product
No certified diver would ever even go near a product like this. The Scorkl does not adhere to whatever EN or ISO standards and is a certain death trap. You'd rather get advice from your local dive shop on getting you Open Water Scuba certification or just do a short 'try dive' to get an idea of the requirements and safety procedures underwater, to prevent serious harm or death.
@paul_young4 You don't even have the slightest clue, what you're talking about, do you? This device will sooner or later kill people, if it hasn't already. I've been a certified diver for over 15 years and would never - not even in an emergency - entrust Scorkl with my life support.
