WARNING: Only use the Seagow underwater breathing system, the MiniDive Pro and other similar products if you’re a certified scuba diver. DO NOT buy it or use it otherwise. Although the Seagow and MiniDive both come with instructions, this is not sufficient for your own personal safety. Only learn to dive with a leading scuba diving organisation like BSAC or PADI first. Note that scuba diving is a dangerous sport. It becomes even more dangerous if done when not certified!
