Scuba divers are typically loaded down with quite a bit of heavy gear. The Avelo System is designed to help in that regard, as it moves the functionality of the buoyancy compensator into the air tank, making the former unnecessary.

When it comes to communicating with one another while underwater, scuba divers typically use either hand signals or writing boards … both of which have limitations. Soon, however, they could be utilizing an app on their existing smartphone.
