Mares is Recalling All Nemo Air Computers: If you’ve got one, contact your dealer now. Mares issued a recall last summer for the slow-leaking O-rings on the Nemo Air computer’s Quick Connector hose, but it turns out the replacement O-ring issued wasn’t the solution. On February 1, Mares announced another recall for the entire hose. “We designed a new quick disconnect system to replace it,” Mares’ national sales manager Steve Lamphear told Undercurrent. All Nemo Air dive computers need this replacement so contact a Mares dealer to get the hose replacement, free of charge. If you want Mares to do the replacement, call Customer Service at 800-874-3326 and give them your computer’s serial number for shipping info.

Undercurrent Blogs: If you haven’t been following our blogs, you’ll get plenty of information, laughs and education from guest bloggers like Bret Gilliam, the deepest air diver ever; Doc Vikingo, peripatetic columnist; Burt Jones and Maurine Shimlock, who just completed an excellent book on Raja Ampat; John Bantin, the equipment editor for Diver magazine; and many, many more. Go to Undercurrent and click on blogs.

And A Regulator Recall From TUSA: It’s taking back RS-670 regulators sold between May and September 2009 because loosening of the BLC plug on the first stage may cause a high-pressure leak. Affected units have first stage serial numbers between 22 and 29, 31 and 103, 637 and 676, 708 and 716, and 737 and 776. Take your regulator back to the dealer, or contact TUSA at or call 800-482-2282 to mail it back for repair, covered under warranty.

Great Free Online Dive Medicine Book: Carl Edmonds, co-founder of Australia’s Diving Medical Centre, alerted us that his formerly out-of-print book Diving Medicine for Scuba Divers has just been updated for 2010 and, better yet, is available to download for free online: ( This classic book, which Edmonds co-authored, deals with dive-specific health issues, their causes, first-aid and prevention. You can download any of the 43 chapters, from Panic and Fatigue to Drugs and Diving, one at a time, or the entire book. Edmonds encourages you to download his book onto a CD/DVD to take with you on your next dive trip, or just pass on to fellow divers.

Coral Reefs Need Your Foreign Currency: Admit it. You’ll never use those foreign bills in the bottom of your drawer, so send them to us to convert into greenbacks and apply them to a project to save our oceans and reefs. It’s tax-deductible and I’ll send you a receipt for your contribution greater than $50 (Undercurrent is a 501c3 organization and contributions are tax-deductible). So far, we have outfitted a sailboat so rangers can stop night poachers on Belize reefs, and helped build a school in Fiji, for which the chiefs established marine-protected areas totaling 3,010 acres and a 4,752-acre forest preserve. Send the bills to me: Ben Davison, P.O. Box 3020, Sausalito, CA, 94965. And feel free to include a tax-deductible personal check made out to Undercurrent as well. If divers don’t save the reefs, who will?

A New Online Guide for Underwater Photographers: Here’s a new site underwater photographers of all levels can check out for tips. Underwater Photography Guide ( offers an online tutorial book from Santa Monica-based diver and photographer Scott Gietler - check out the Chapter Index to get straight to info on wide-angle optics, image sharpness, post-processing and more. Every week, Gietler posts new articles on photography theory and technique, and equipment reviews. Or sign up for a monthly e-mail newsletter. All information is free to read.

Kudos To Louie Psihoyos And The Cove: Psihoyos, the National Geographic photographer turned filmmaker, has been winning a slew of awards for his feature-length documentary, a stealth effort by divers to document the dolphin slaughter at Taiji, Japan. The Cove won Best Documentary at the Critics Choice Awards, and the Directors Guild of America named Psihoyos the best documentary director of 2009. Now The Cove is an Oscar nominee for Best Documentary. See if it wins on March 7; and The Cove is now available on DVD. P.S.: I helped Louie raise $20,000 to subtitle The Cove in Japanese for distribution in Japan.
