September 2012. GoPro Hero HD (original) + Halcyon 21W HID & diffuser. The 'Illinois' is a US tanker hit by a German U-Boat in the English Channel in 1917 and one of the most intact wrecks of the WWI era. She lies on the edge of the Channel shipping lane at a maximum depth of 70 metres. This is a brief video of 3 dives we conducted on her in September 2012 during a fortunate late summer break. These are some of the highlights I captured. Scenes on the deck were taken at an average depth of 54 metres with seabed at about 65.
