Be Careful Buying a Computer   January 24, 2022

The Blue Planet Dive Shop in Washington D.C. was bilked out of $4000 worth of Garmin dive computers by customers using stolen credit cards. Two other shops were similarly scammed, one losing more than $10,000; Shearwater computers were among those stolen. They learned of the theft after a cardholder detected the purchase. Typically, this kind of theft is done over the phone, with the purchase shipped to a vacant house, a mail drop, or someplace the thief can't be identified. In this case, the computers will probably end up on eBay or some other online marketplaces. Buy your dive equipment only from a legitimate dealer. You don't want to end up with stolen goods that no longer have warranties. The stolen computer serial numbers are on file with authorities.

World Shootout Underwater Photography Winners

World Shootout Underwater Photography Winner  January 24, 2022

World Shootout Underwater Photography Winners will be announced live online on January 29 at 10.30 a.m. Pacific time. Itís a 16-year-old global competition, in which amateur and professional underwater photographers submit photos in 12 categories. We understand that some Americans are among the overall winners this year.

Thinking About Bonaire for your Next Dive Trip  January 24, 2022

"Just during our month here, December-January, we have seen the entry rules change twice, thanks to the Omicron variant," our long-time correspondent tells us. "Bonaire hoped to keep it out, and thus enforced strict entry rules, but last fall rules were relaxed in favor of frequent testing and restrictions on gathering. In mid-January, restaurants are limited to 50% capacity and no more than four per table. That means no big dive club tables! Sadly, the government continues to let floating COVID wards, aka cruise ships, dock and overrun the island with cruise passengers driving golf carts spreading COVID. The good news is I noted fish I had not seen on the west side -- hogfish, a nurse shark, abundant yellowtail snapper, more tiger and black grouper -- and delighted in seeing a pair of seahorses in the same place I saw them last summer. Be careful with your rental car: long stretches of busy roads are more potholes than roadway."

X-Deep Recalls its NX700 Regulator: Stop Using It  January 24, 2022

During routine servicing of some NX700 first stages, technicians have discovered excessive membrane wear in some regulators. Consequently, all existing NX700 first stages have been recalled, and the dry chamber body will need to be replaced. If you own an NX700 first stage, stop using it immediately and contact the dealer from whom you purchased it. More info:

Close and Far?  January 24, 2022

If you wear glasses, you most likely need corrective lenses underwater. Consider getting a mask fitted with either positive (close reading) or negative lenses at your dive store. The TUSA Ceos is a popular example. For close-up viewing, you can have your standard mask fitted with a positive lens in the lower part to partly function as a bifocal. To solve his vision problem, Blue Planet cameraman Peter Scoones had a plus-lens in one side of his two-lens mask and a negative in the other. He said his brain soon sorted it out, and he had perfect vision restored for both close and far subjects. Have your dive store help you out.

Immaculate Coral Reef Discovered   January 24, 2022

Stretching across the ocean floor for nearly two miles, a huge coral reef has been discovered off the coast of Tahiti in French Polynesia. Itís in the Pacific twilight zone and offers hope that more pristine ecosystems are discovered at unexplored depths. Itís more than 100-foot deep, where sunlight levels are low, but it does not appear to have suffered any bleaching events. Most of the worldís known coral reefs are at depths of less than 80-feet.

Have You Experienced COVID on a dive trip?   January 24, 2022

Have you been unlucky enough to be on a liveaboard that had its trip curtailed because there was an outbreak of COVID on board? Or at a dive resort when others, or even you, became COVID-positive?
