Hollis Recalls Some Explorer Rebreather Models:  March 21, 2014

Hollis has recalled certain counterlungs for its Explorer rebreather. "We have traced this problem back to one production lot of counterlungs that had weak welds around the retainer fitting, and affected counterlungs can develop leaks over time," the company said in a press release. It has published the serial numbers on its website, and divers with affected counterlungs should contact their local Hollis rebreather dealer; the company will send a free pair of new counterlungs. For more details, go here.

Dive Computer Buddy Meets Its Crowdfunding Goal:  March 21, 2014

DiveNav, a maker of digital dive tools for smartphones and computers, recently went on the crowdfunding website to raise money for its latest product, Dive Computer Buddy, which lets divers quickly download logs from their dive computers to a tablet or smartphone. They asked for $20,000 and raised $25,000 in less than 30 days. With that money, the plan is to put the Dive Computer Buddy app inside its already-on-the-market tool, divePAL, which lets divers plan, analyze and log dives. DiveNav plans to release versions of the dual tools that support model-specific dive computers this summer, with Suunto computers being the first to be supported in June. Aeris, Oceanic, Sherwood and TUSA Zen computers will be added to the group in July, followed by the Mares Puck family in August, and the Cressi Leonardo, ScubaPro and SubGear models in September. For more details about Dive Computer Buddy and divePAL, go to here.

Choose Your Dive Boat Wisely:  March 21, 2014

If you're going on a dive trip overseas and opting to go out with a local dive operator while there, choose wisely. From boat explosions to boat "captains" who don't keep track of divers, Second- and Third-World dive destinations are rife with accidents that injure or kill visiting divers. A recent example: three Thai liveaboards that sank within a three-week period. Read how it all happened in this month's issue; "Choose Your Dive Boat Wisely" is free to read at the top of the homepage at

Bravo, Hilton Worldwide:  March 21, 2014

The hotel chain announced last month that it would stop serving shark fin and accepting new orders for shark fin dishes by April 1. The ban will then be effect in its 96 owned and managed Hilton hotel properties across the Asia Pacific.

Boat Captain Charged in Diver's Death:  March 21, 2014

In this month's issue, we wrote about seven divers who got swept away by bad weather on February 14 while diving near Nusa Lembongam, a small island near Bali, leaving one diver dead, and another missing and presumed dead. The latest on that story: The captain of their dive boat was charged with negligence two weeks after the incident. The five divers who survived the ordeal told Indonesian police that the boat captained by Agustinus Brata Kusuma could not be found after they surfaced from a 30-minute dive. Kusuma told police the weather became cloudy after the divers submerged, and he followed their bubbles in an attempt to locate them. However, the head of Bali 's search and rescue team challenged that account, saying he had information suggesting that the skipper had left to refuel before heading to the agreed meeting spot. Police charged Kusuma with criminal negligence causing death, and if convicted, he could be sentenced to up to five years in prison.

Manta Rays are Safe in Indonesia:  March 21, 2014

Last month, Indonesia announced it would become the world's largest manta ray sanctuary. The archipelago's 5.8 million square kilometers of ocean are protected from manta fishing and export. That's because government officials were persuaded by evidence that mantas are worth more alive than dead -- a study published last year in online journal PLoS One said a manta ray is worth up to $1 million during its lifetime, thanks to tourists who will pay to swim with them, but only worth up to $500 when dead. Now conservation groups are teaching fishermen about the value of manta ray tourism, and more than 200 policemen have been prepped to enforce the law.

A Common Chemical Kills Coral Reefs:  March 21, 2014

Thanks to subscriber Jonathan Scott (Waltham, MA) for alerting us to research showing that a common chemical used in many soaps, shampoos and cosmetics is killing young coral reefs at concentrations commonly found in the environment. The study, in this month's issue of Ecotoxicology, found that benzophenone-2 (BP-2) is toxic to coral reefs, causing increased rates of death and bleaching. BP-2 is found in U.S. wastewater, and once in the environment, can quickly kill juvenile corals at even low concentrations. BP-2 is similar to oxybenzone, the active ingredient in many sunscreens (although it is not used in U.S. sunscreens), and it is considered an emerging contaminant of concern by the EPA.
