I've been diving and exploring since 1989, having being introduced to it while at university. Back in late 1997, I pulled together the DIR-UK dive team and over the years we've grown, done some pretty cool diving and more recently started doing some video.
We've run expeditions to France, Florida, South Africa, Mexico, Scapa Flow, Shetland Islands, Australia and Vanuatu.
