As colourful fish were swimming past him off the Greek coast, Cathal Redmond was convinced he had taken some great photos with his first underwater camera. But, when he looked at the results on dry land, the images were brown and murky. Having taken the pictures while holding his breath underwater, he blamed the limited time he had to set up the shots. All he needed, the industrial designer thought, was a little more time to properly capture the fish in their natural environment. He vowed to make the little extra time needed a reality and the result is his invention of the Express Dive – a refillable air storage device, held in the mouth, that lets users swim underwater for two minutes. It is aimed at bridging the gap between snorkelling, with its limited scope, and scuba diving, which gives divers the freedom to breathe underwater but at the cost of using cumbersome and expensive gear. The prototype of the invention – which is still in the initial stages of testing individual parts – looks like a cross between a scuba mouthpiece and a water bottle. “I wanted to enable people to do more. So, rather than just get in underwater and spend 30 seconds holding their breath, I wanted to do a little bit more than they were able to do,” says Redmond, 27. In 2006, the Irish designer completed a scuba-diving course and loved the feeling of being able to breathe underwater
