Four years ago, we heard about a neck-worn device that wirelessly transmits an alert if its wearer should happen to start drowning.
Well, the Ploota takes things a step further – it actually deploys two airbags, to bring its user up to the surface. And unlike some similar devices, it keeps them floating in a head-up position.
Although the Ploota can be submerged briefly without being activated, it has a sensor that detects if it stays under for more than 30 seconds.
Should this happen, it is assumed that the user is in trouble, as opposed to just being good at holding their breath. The two airbags are then inflated, bringing the wearer back to the surface.
