Many Tanks Needlessly Condemned  April 18, 2017

Professional Cylinder Inspectors Inc. (formerly known as PSI Inc.) says that there has been confusion over incorrect information on the US DOT (PHMSA) website, leading to many cylinders needlessly getting condemned. If youíre in the business of filling tanks or have had a tank condemned, visit

Did You Miss the Boat?  April 18, 2017

If you were contemplating a visit to the wreck of the RMS.Titanic, you might be too late because trips on Blue Marbleís purpose-built titanium and carbon-fiber submersible to the mighty vesselís final resting place two miles down, are fully booked. At $105,129 per person, itís is almost twice as much of that of the last Titanic tourist trip on the Deep Ocean Explorer in 2012. However, not to worry if you missed this opportunity. Los Angeles-based company, The Bluefish, is taking reservations for a similar expedition in 2018-19. Price yet to be determined, but it will include the eight-day round trip from Newfoundland.

Scuba Boots Meet Main Street?  April 18, 2017

There are Two Types of Divers  April 18, 2017

Those who pee in their wet suits and those who lie about it, hence the common aura encountered on dive decks. Regardless of your standing, if youíre one who likes to jump in the resort swimming pool in your wetsuit after a dive, you may wish to know that a research team testing 31 pools and hot tubs in Canada found evidence of urine in every single one of them. Environmental Science and Technology Letters reports that they found an average of eight gallons of urine in a typical 110,000-gallon pool. As for hot tubs -- you donít want to know. While urine may not be harmful, it can react with chlorine to create by-products known as DBPs that can lead to eye and respiratory irritation.

The Pros and Cons of Shark-Feeding Dives  April 18, 2017

We asked what you thought of dives where sharks were either baited or fed in order to bring them close for divers to see. Itís actually illegal to do so in Floridaís waters but there are moves afoot to make it also illegal elsewhere in the US. That said, the nearby Bahamas have a burgeoning shark diving industry, as do several other parts of the world. We were inundated with informed opinions representing both sides of the argument and we hope weíve put together a balanced view of those. Itís free for you to read this month in
