As a proponent of 2 adults with a junior diver, I’d like to point out something else, in the case of a junior diver and an adult diving alone, where an emergency arises with the adult. It should be considered, not only, whether the child would know what to do to help the adult with the emergency; but also what happens to the child alone after something happens to the adult. Would a child have the ability in a scary situation like that to get themself to safety?
