Aladin Air X Nitrox Computers Recalled – At Last March 27, 2003

UWATEC AG, of Switzerland, is recalling about 390 Aladin Air X Nitrox dive computers manufactured in 1995. The software "may inaccurately calculate desaturation times, resulting in possible decompression sickness under aggressive dive conditions." UWATEC has received five reports of DCS "allegedly associated with use of the 1995 dive computers." UWATEC has stated, "For safety reasons, we ask that you stop using the 1995 dive computer immediately." To which we can only reply, "What took you so long?" You see, the defect has been known for several years and lawsuits have been filed against UWATEC and Johnson Worldwide (which purchased UWATEC and owns Scubapro) alleging fatal coverups. The full story appears in the April issue of Undercurrent. Meanwhile, if you have a '95 Aladin Air X Nitrox computer, stop using it and contact UWATEC for a free replacement (the $900 Air Z Nitrox). See the firm's website at, or you can call 800-806-0640

Fatal Depth: Deep Sea Diving, China Fever, and the Wreck of the Andrea Doria March 27, 2003

In the summers of 1998 and 1999, a 65' dive boat from Montauk, N.Y., lost five divers in separate incidents on the Andrea Doria – about one diver in every four trips! Diver error? Captain error? Bad luck? A continuing, unaddressed problem? Joe Haberstroh, a reporter for Newsday, explores each death in detail, explaining the divers’ motivations, their training, and what happened on their fatal dives. The divers are ordinary guys, some trained better than others, but each diving below 200 feet in search of Doria trophies. What happened on board the Seeker? What was the Captain’s role? Could the accidents be prevented?. This is a fascinating book any serious diver will find difficult to put down. I read it in a day. Just published this month, it’s available through Undercurrent’s link to, where a good portion of your purchase price will be donated to the Coral Reef Alliance. Hardbound, 250 pages, $16.77 currently at Amazon.

What Can Women Teach Men About the Bends? March 27, 2003

An extensive study was conducted in the United Kingdom, involving 2,250 divers, 47% of whom were women. Of the 458,827 dives reported, 31 percent were by women. Differences in diving habits were observed between men and women, which included the number of dives per annum, maximum depths dived, and number of dives with extra stops. The findings were a surprise. When they considered experience, the rate of DCS in men was 2.6 times greater than women. Further studies are needed. (Space Environmental Medicine 2002 Aug)

Going Full Circle March 27, 2003

A British organization, The Full Circle Expedition, conceived by British dive journalist Monty Halls, has what it calls “the 10 top dives” in the world: Great white sharks, South Africa; Aliwal Shoal, South Africa; Lake Malawi, Palau Archipelago; Yap; Great Barrier Reef; Poor Knights Islands, New Zealand; Galapagos Islands; Blue Hole, Belize; Little Bahamas Bank. During 2002, expedition participants dived all 10 sites in a three-month period and loved it so much that they're going to do it again in 2003. If you have nothing but time and money, visit their website at for more information about the expedition or to apply to join the group.
P.S.: You don’t have to make all the sites, you can pick and choose or take other trips, such as wreck dives, with them.
