Are there any scuba diving fans in the room? Because we advise you to take a look at this: a diving tank that is far from invasive, since it is portable and can be recharged by hand in a few minutes.
The project is called MiniDive Pro, and it is the work of a French startup: SARL AIRSCPE, based in Le Puy-de-Dôme. The concept: a portable, lightweight diving tank that can be recharged at sea using a hand pump (supplied with the tank) or a mini compressor (optional). Of course, the MiniDive Pro does not allow expeditions of more than 5 or 10 minutes, but it is sufficient for Sunday divers, for emergencies or for long expeditions, which cannot necessarily reload traditional tanks. In addition, the device has a lightweight harness to quickly put on and remove the device.
MiniDive Pro was the subject of a participatory fundraising campaign on Indiegogo that was funded at more than 430% of its initial target.
