Though double (twinset) tanks and stage bottles are generally a requirement for most technical diving operations, diving sets vary significantly depending on the specific application and diving environment. Here’s a look at some of the more common methods of set rigging as practiced today in the “doubles community.”

Adventurous types, submarine enthusiasts, explorers and submersible operators can sign up for a selection of pilot training courses to be held in August 2015. No experience is necessary, as U-Boat Worx’ expert instructors will teach all the ins and outs.

Courses will be held off the island of Malta in the Mediterranean Sea, known for its crystal-clear waters and abundance of world-class shipwrecks. A fully-equipped 30-meter yacht will support the training courses and take the pilots to all the best dive sites.

Underwater Nanaimo

I am often asked, “Where is the best place to photograph underwater critters in British Columbia?” Well, there is certainly no simple answer to this question and I usually end up replying something like this; “Unless there is a plankton bloom, bad weather or visibility is poor, there are no bad places to dive in BC, therefore you can see critters on every dive!”

This is especially true around Nanaimo, a popular hub destination on Vancouver Island that is easy to get to and can be frequented by divers on a year-round basis.

Is Diving Really Safe?

Admittedly a rather contentious title, but it's supposed to be. Debates over whether diving, or even certain types of diving, are safe sometimes get emotive and heated, depending on the arguments being made. These include: Is closed circuit rebreather diving safe? How much safer is recreational rebreather diving than open circuit? Is cave diving safe? Is recreational diving to 18m on open circuit safe?

The simple answer is—it depends! This article will present a series of arguments so the reader (and diver) can make that decision, as ultimately, it is the diver who is choosing to get in the water and expose themselves to the risks therein.

British Columbia: Diving Canada's Freshwater Interior

Although British Columbia’s (BC) coastal area offers numerous shipwrecks, colorful walls and reefs full of life, there are also a considerable amount of freshwater lakes and rivers to explore within what is known as BC’s Interior Region of Canada. Actually, you might be surprised at what you will find to do and see above and below the water.

On many occasions I have joined friends and dive groups to check out some of the more popular Interior destinations, but I was amazed to find many more sites were also available. Most of the locations are listed on dozens of different websites, including a few informative You Tube videos.

Florida Keys

Statistics show that more Americans dive in the US state of Florida than any other place on the planet, but when you consider what is on offer, it is hardly surprising. The state’s government has been instrumental in sinking some of the world’s largest (so-called) artificial reefs, but there are also freshwater pools, caves and caverns with a constant warm water temperature all year-round, which certainly appeals to winter divers.

There are great encounters with large critters like manatees. Of course, the farther you travel south towards the Florida Keys, the more the country is influenced by the might of the Gulf Stream. There is great ease of access down to the Sunshine State.

Pavillion Lake

I first learned about this unusual lake, nestled in Marble Canyon Provincial Park of British Columbia (BC), Canada, when some friends living in Kamloops asked me to join them for a dive at a local, clear freshwater lake. Since it was only a few hours from Vancouver, I decided to take them up on their offer and headed for the interior parts of BC.

I have always wanted to explore this area and was thrilled even more when they told me of the strange coral-type of life living in the lake.

The Perfect Diving Breath

Confronted by a genie in a lamp and three wishes, many new divers would ask for a magic spell to make their air last longer on a dive. The good news is that you don’t actually need a genie in a lamp—the key to better air consumption is not a secret at all.

Divers usually find that their breathing rate drops as they become more experienced, simply as a consequence of their becoming more relaxed and comfortable in the water.
