Freedivecomputer with Underwater Communication

Описание: This is the first prototype that offers communication between many freedivers underwater. The data streamed to each device is depth, temp, time underwater and Heart rate. Due to the sunlight, only the lower part for the currently diving freediver is visible.
Heart rate is wirelessly transmitted from the worn chest strap. During the video, the divers chest strap moved. Therefore the BPM is not accurate.
The depth rating of the whole system is 300m.
The communication distance between the two devices is 200m.
