Been a couple of times on LW. It is something else to see folk 70m below you swimming around on a wreck as the vis is just that good.
There are only a few places in the world where you can see proper big guns on a battleship and I have been lucky enough to dive several of them including the Audacious. Seeing 13.5 inch shells scattered around the place is a sight, you don't see it very often.....
I actually stopped diving just over a year ago and sold all the kit to help buy the new RIB. Then I made the mistake of watching videos on Youtube of dives on wrecks that I always wanted to dive and never had a chance to do, now I am saving up to buy a Rebreather to go back and dive them!
Incidentally we are coming over to rathlin for a run in the next few months when we get better weather, will post when and where as we have an offer of accomodation in Campbeltown.
