Part 7 James Egan Layne A close neighbour to HMS Scylla, the James Eagan Layne is a very different type of wreck. A WW2 Liberty ship, she was sunk by a torpedo on her maiden voyage. Lying at 28m, she offers a very atmospheric dive and - with such a sense of history as well as plentiful marine life - she is an underwater photographer's dream.
Part 8 Underwater photography The development of digital has had had a huge impact on underwater photography, making it an easier and more affordable pastime for divers. And with the diversity of the UK's marine world, divers are never short of a subject, from the minute detail through to the more dramatic marine landscape.
Part 9 Scapa flow A mecca for wreck divers from all around the world, Scapa Flow is a prime example of the UK's underwater heritage. Just off the north east coast of Scotland, Scapa is home to eight German battleships, deliberately scuttled by their own navy in 1919. Lying at depths between 30-40m, Scapa's ships provide awe-inspiring diving and are a real treasure of our seas.
