Deep wreck diving

19 Apr, 20:00 on BBC Four: Dive WWII: Our Secret History - 1/2. Jules Hudson presents the first of two programmes following a deepwater dive team searching for the wrecks of WWII’s Battle of the Atlantic off the coast of Northern Ireland. Also in HD. [S]

This is the kind of diving I used to do, 60m plus mixed gas rebreather, all data passed off to historians.

I know and have dived with some of the people in this programme.
