Swedish startup Team Oceans has unveiled the Oceans S1, a personal multifunctional device for divers. This is an analogue of an underwater smartphone with the difference that instead of radio waves, which propagate poorly in this environment, it uses ultrasound for communication. True, it will not be possible to talk in the usual sense - this is a system for maintaining contact between paired devices.
The Oceans S1 gadget is made in a smartwatch format, is worn on the wrist and provides a basic set of information services for a diver. In particular, it contains a digital compass, a depth sensor, a timer for monitoring the remaining oxygen, a water temperature sensor, data on the maximum depths in these places. Information is displayed on a 2.2-inch color LED Retina screen and can be transmitted via Bluetooth to an iOS / Android application on the user's smartphone as soon as he gets out of the water.
By "connection", the authors of the startup mean the ability to quickly "ping" group members under water. It is enough to press the button and for all divers within a radius of 15 m, their Oceans S1 will begin to vibrate on the arm, and the screen will display the signal from whose device the signal was sent. Then you will have to interact in the old fashioned way, with the help of gestures, but you do not need to wave your hands in order to initially attract attention to yourself. And it is a matter of technique to develop the simplest code for transmitting basic commands to a group. As a last resort, old and proven Morse code is fine for this.
Oceans S1 weighs 95 grams, can withstand diving to depths of 50 m, can work up to 10 hours without recharging. The internal memory is sufficient to record 500 dives or approximately 80 hours of operation. The price of the device for startup investors is $ 325, when the product goes to market it will rise to $ 565.
