Acoustic navigational tech gets scuba divers using GPS maps

Good news!

"Manufactured by German underwater tech company EvoLogics, DNS consists of three main components: a tracker unit, a diver console, and a USBL (ultra-short baseline) buoy. ...
Floating at the surface over the diving area, the buoy continuously sends acoustic "pings" through the water. These are received by the tracker unit, which is mounted on the diver's air tank. The tracker automatically responds to each initial ping with a reply ping of its own, which is received by the buoy. ...
As an added bonus, the console also lets divers send and receive simple preprogrammed text messages to and from one another – again, the data is transmitted via acoustic pulses. The topside crew can also send and receive such messages via the Wi-Fi-linked buoy. ..."

"The innovative system facilitates map-based navigation for divers on a mission, offering the flexibility of seamless two-way communication between divers and the dive supervision team, and setting map waypoints both during a mission’s planning and execution. ...
With the new system, EvoLogics aims to streamline complex underwater tasks such as search and rescue, salvage operations, recovery efforts, and cleanup operations. The Diver Navigation system enhances coordination, improves task management, and promotes efficient information sharing, ultimately enhancing the effectiveness of diver operations. ..."

Acoustic navigational tech gets scuba divers using GPS maps Because GPS doesn't work underwater, divers usually can't track their real-time position on a digital map. The new Diver Navigation System (DNS) gets around that problem, however, using both floating and wearable acoustic transponders.
