Tricky - what did you think of the M2?
The reason I ask is when I learned to dive everyone seemed to be diving teh M2 - but I was warned that it was a challenging dive for a newbie - so never did it.
I could probably cope with it now
but I've tried to book it a couple of times when I have had charters but have been out voted each time by others on the boat - saying 'boring - long metal tube' Now to be honest each of them is saying it from the position of having dived it - and I haven't.
What do others who have dived it think?
