Deep Dive: UL Student wins James Dyson Award

For the second time in as many years the University of Limerick has had a winner inits ranks of the Irish James Dyson engineering award. Cathal Redmond, 26, won this year for his unique Express Dive device which allows for divers to breathe underwater for up to two minutes. His innovative creation allows the one litre tank to refill at the touch of a button once the air supply begins to run out.
It combines the technological advancements of SCUBA diving with the ease of a Snorkel system, making the system more user friendly for novice and prosumer users. ‘Express Dive’ is smaller, lighter, cheaper and easier to use than any SCUBA system on the market. A full scuba kit can cost in the region of €3,000, as opposed to an estimated €400 for the ‘Express Dive’..
While on holiday in Crete, Cathal was inspired to come up with the device when he realised that overcoming shallow water would be possible in a new exciting way using a device like this one.
“This light weight device is perfect for shallow surface-to-surface diving, exactly the kind done every day by novice explorers using snorkels. My device fills the space between snorkeling and scuba, SCUBA still exists for deeper diving, but my device makes the experience portable, refillable and more usable. The System comes equipped with a depth alarm and air shutoff to protect the learning diver from diving too deep, and a digital display of remaining air.”

He receives  €2,500 from the James Dyson Foundation and will proceed to the international stage of the James Dyson award where the shortlist is announced on September 17th next. . He joins over 600 students from 20 countries for the grand prize of €37,500 to help further develop his device.
