Mackenzie Moulton (known as Mac) spent 30 years in the Met Police, London. The last 13, in the elite Underwater Search Unit, both as diver and dive supervisor. He has already written a book 'London Police Divers Stories', about some of his most memorable incidents. He thought people might like to see his actual log book, not only showing police dives but pleasure dives as well. This was required so that there was a full record of his diving for obvious reasons. This is one of three he filled out in the 13 years he was a police diver. I hope you enjoy this unique insight into police diving.
