I surfaced from a night dive a while back and noticed water in my Light Cannon. I took it home and dried it out with a blow dryer, put in new batteries and fired it right up. I used if for another 6 months or more on about 20 mores dives before it started cutting off on me. A couple of weeks ago I took it to my LDS and they sent it into UK. The light was back in less than a week will all new guts. Only the bulb and external case are original. oh yeah, no charge! :winky2:
