Hi Wibs. Like you, Iím having similar problems with my NW7. Unlike you at the moment Iíve found their service department very helpful. Anyway to answer your question as to which torch to go for. Take a look at a Seawolf A2260. As far as I know, they are a UK firm. Donít know much about them except to say that two guys I was diving with last week in Scapa had them and they were seriously bright! It was like a scene from Close Encounters when they were swimming towards you.
