Dell, I think the WKPP guys carry a backup slug because it would be pretty uncomfortable doing a 2 hour exit on backup lights for something like a broken bulb or test tube. For normal dives, no backup slug needed. At 10:17 AM 8/5/1999 -0400, you wrote: >I've been diving several different designs of HID for several years now. The >configuration is the same.
