I just thought I'd give a shout out to one of my favorite new dive toys. It's the XS Scuba Lt360 dive light. I picked up one of these a while back and love it. It puts out a very impressive 1000 lumens of light in a wide arc. It's certainly bright enough to light up the back of almost any hole. The body is made of a strong milled aluminum. Best of all it's rechargeable. When I have used it the battery has had more than enough power to last a full day at full power. The light also uses a magnetic switch that helps to prevent leakage because there is no hole in the housing. They aren't cheap, selling for between $160 and $180 depending on where you get them, but in my opinion they are worth it. When it comes to hole hunting a good light makes all the difference so don't buy one of those cheap under powered jobs.
