With the development of the maritime tourism industry, underwater diving has become an explosively popular sport. With the shift from the traditional dive watch to the now ubiquitous dive computer, recreational diving has taken its leap towards the digital age. The mask however, has stood still. ZJ-DDG's D-Mask concept serves to highlight the potential of the dive mask. This ultramodern piece is equipped with bone conduction technology, bringing underwater communication into the future. A heads-up projected display also serves to indicate vital information such as the water conditions and weather, all while your eyes are still focused on the view in front of you.
