This is a video of the last 5 minutes of a dive at the slates (also known as ballachulish slate quarry) in Scotland. There where four of us diving on the site. Myself and lewis where up front and mike and Phil where following along behind us. in this video we swim up a valley until we encounter a small rowing boat and an old cement barge lying in about 15 metres (about 50 feet) of water. After myself and lewis reach the barge phil gives an out of air signal to mike as a training exercise. Phil then breathes of mikes backup regulator and they swim along the remainder of the way to the wreck. We then head to the surface directly from the wrecks.
