Corrected New Travel Rules for Handling Batteries :  January 07, 2008

In Tuesday's e-mail about lithium batteries, many readers reported that we were too general and perhaps misleading about the new travel prohibitions regarding them, so we decided that we should further clarify our information and direct you to official federal sources in case there are further changes.Department of Transportation spokesperson Patricia Kliger told Undercurrent that the checked-baggage ban on loose lithium batteries of all sizes was primarily put in place for industrial-size batteries, like those used in heavy-duty audio/video equipment, because they can pose a significant fire hazard. The new restrictions do not have much of an effect on consumer electronics, however, you may not pack ANY spare lithium batteries in your checked bags. It is okay to check your gear as long as batteries are installed in them. Other rules for traveling with spare lithium batteries : * You can bring batteries with up to an 8-gram equivalent lithium content in your carryon bags. All lithium ion batteries in cell phones are below the 8-gram equivalent lithium content. Nearly all laptop computer batteries and those used by photographers and dive computers also are below this quantity threshold.
* You can also bring up to two spare batteries with an aggregate equivalent lithium content of up to 25 grams, in addition to any number of batteries that fall below the 8-gram threshold.
* For a lithium metal battery, whether installed in a device or carried as a spare, the limit on lithium content is 2 grams of lithium metal per battery.
* Almost all consumer-type lithium metal batteries are below 2 grams of lithium metal. But if you are unsure, contact the manufacturer!Remember all spare batteries you carry with you should be in the original case, in individual plastic bags, or have tape over their contacts.

Oceanic and Aeris Recall Regulator First Stages :  January 07, 2008

Oceanic is recalling FDX-10 and CDX-5 first stages and Aeris is recalling its T400-type first stages. The bad parts were shipped to retailers between May 1 and November 15, 2006. But Oceanic's other DX series First Stages (CDX, DXi, DX3, DX4 and TDX5) and Aeris's other diaphragm-type first stages that were serviced between May 1, 2006 and October 22, 2007 may also be affected.

Wife-Killing Diver Nabbed By Feds :  January 07, 2008

David Swain, the Rhode Island dive shop owner found guilty by a civil court for murdering his wife Susan Tyne while diving in Tortola, was arrested by federal authorities. Attorneys said circumstantial evidence, including his behavior after her death, apparent financial motivation, and Tyne's gear showing signs of a violent struggle, was "overwhelming." The civil court ruling last year ordered Swain to pay Tyne's parents millions in damages. Now, eight years after the incident, he is facing extradition to the British Virgin Islands for a murder trial. (For the full story, subscribe to Undercurrent and read our April 2006 issue online.)

How Do You Tip? :  January 07, 2008

We're doing an upcoming article on good, bad and just plain unusual tip policies. Do you know a liveaboard, dive resort or scuba operator with one of these? For example, subscriber George Coughlin was on an Indonesian that had two tip boxes, one for the dive managers and one Indonesian dive guide, and another tip box for the other 25 members of the Indonesian crew. "The dive manager told me the latter wanted it that way! But it just seemed that crew weren't viewed as important as the others," says Coughlin. In what situations have you been glad to tip - or outright refused to do so? Furthermore, how much do you tip? To whom, and on what basis? As traveling divers, we need to share this important information because on dive trips running at $1,000 to $3,000, tips can become a big hunk of expenses. So how do you tip? Send your comments to
