Another Cocos Tiger Shark Attack  May 17, 2018

A lucky 30-year-old German male diver escaped intact after being attacked by a tiger shark near Manuelita Island, Isla del Cocos, Costa Rica on April 28. The animal bit into his tank and BC but he managed to free himself from his rig and swim to the surface while the shark ripped his gear to pieces as other divers look on. He was shaken but unhurt. Last November, an American, Rohina Bhandari, died after a tiger shark attacked her at the same location (Undercurrent January 2018). This is the sixth confirmed unprovoked shark attack in Costa Rican waters since records began.

Donít Flame Your Mask  May 17, 2018

Last month, we reported to our subscribers that a few Hollis masks had shattered when a diver hit the water, and now we have found the culprit: not the mask, but the diver. As you know, you must polish the inside surface of a new mask to remove the coating and prevent it from fogging. However, some divers try to burn off that coating with a cigarette lighter, but this can weaken the tempered glass and may result in a frameless single face-plate mask shattering on impact with the water, especially if the strap is pulled so tight it stresses the weakened glass. The proper way to remove the film is to polish the glass with a gentle abrasive such as old-fashioned white toothpaste.

“Me Too” in Diving, a Free-to-Read article in Undercurrent  May 17, 2018

This month we examined serious problems women have experienced diving as relayed by a number female subscribers. Could there be a patriarchal or sexist attitude to female divers? Have you or do you know a female whoís experienced unfortunate attitudes while abroad or even when diving at home? Do some dive guides patronize women and assume they are inexperienced divers? Worse than that, have you experienced or witnessed outright sexual harassment when diving? Read Vanessa Richardsonís article here.

Surface Marker Buoys in Cold Water  May 17, 2018

Donít use your regulator or octopus to inflate it if the temperature is less than 46°F/8°C, says Martin Woodward, who operates Stoney Cove, a popular inland dive site in the UK. In such cold water, he notes, modern high performance regulators may free-flow, so many manufacturers now caution against it.
