Swedish Company Oceans has a new concept that aims to revolutionize underwater dive computers. Their attractive (and full-featured) computer has one feature in particular that they believe sets theirs apart from others – buddy communication.

The Oceans S1 Supersonic dive computer uses soundless ultrasonic waves to allow divers to summon their buddies, dive master or instructor with a tap of a button. When activated, the S1 sends a ping message to each paired dive computer, and shows a notification on the display with the name of the diver looking for attention.

The biggest obstacles and challenges in developing the computer have been cleared and Oceans is ready to go into final design and production. The last step is to put the device into production and finish software development for integration into the Oceans app, and to reach that goal, Oceans has launched a Kickstarter campaign.

Pre-Release Pricing

The Kickstarter rewards come in two variations: a single Oceans S1 Supersonic (with 2 early bird specials) and a buddy pack of two units at a discounted price. The box contains the Oceans S1 Supersonic dive computer, a wrist band and a quick start guide. The Oceans app can be downloaded for free at oceans.io


The S1 charges using any standard wireless charger (Qi). To keep price, shipping cost and environmental impact as low as possible, no charger is included in the box. If you do not have a wireless charger already, it can be found in most electronics stores at a low cost.
