Folding fins
I spotted this sci-fi-looking fin at the DEMA show. As can be seen in the photo, the fin can be folded so that it does not take up much space in one’s luggage.

How do you lift a heavy injured diver out of the water? With RescueX—a light stretcher that also stabilizes the injured.
RescueX was developed by some professional American firefighters (who were also divers) who realized the boards, which lifeguards on beaches were equipped with, were not well-suited for rescuing divers.
This long-established and widely respected contest celebrates the splendor of the oceans and the challenging art of underwater photography and video.
The organizers call on underwater shooters of all levels, from novice to professional, to compete in what has become the “World Championship” of international underwater imagery events.
Imagine you are riding the waters on your trusty surfboard, savouring the rush of emotions and feeling totally alive, when you glance down into the waters and you spot a shark swimming by.
Does your heart skip a beat and you immediately look for the fastest way to get back to dry land?
Or do you continue what you are doing, feeling more at one with the elements?
Well, if you are like more than 50 percent of surfers, you would simply continue surfing, according to a survey of 391 surfers, conducted by the University of South Australia.
Part of sea turtle conservation involves monitoring when turtle hatchlings emerge from the nest and ensuring that they make it safely to the oceans. This method currently involves much manpower and cost, as we cannot predict the exact day and time of this occurrence.
At the time of the spring tide (new moon and full moon), thousands of puffer fish around the world head for the coastlines to spawn. There, they gather at the water’s edge and vigorously tremble their bodies to spawn.
Scientists have long wondered how the puffer fish were able to synchronise their spawning with the lunar cycle.
A paper published in a recent issue of the Current Biology journal has the answers.
Last September, ecologist David Johnson and his colleagues were at a Virginia salt marsh at low tide. There, they observed some unexpected behaviour by an aquatic predator.
They witnessed blue crabs waiting in shallow, water-filled pits, stalking and ambushing fiddler crabs above land, at low tide.
After capturing their prey, they would carry it back to the pit to consume it, then discard the large claws of the fiddler crab at the edge of the pit.
The Mexican government has announced the successful conclusion of a project involving the placement of 193 cement blocks on the sea floor in strategic locations in the vaquita’s habitat.
Called the Concrete Block Planting project, the objective was to discourage the setting of gillnets within the Zero Tolerance Area, where the remaining vaquita population is localised. Large steel hooks protrude from the top of the blocks, trapping any gillnets they come into contact with.
In early October, after nearly three months, the 193rd block was finally placed on the sea bed.
Launched in 1629, Applet (Apple) was built by the same shipbuilder as the famed 69-metre Vasa, which was carrying 64 cannons when it went down in a strait off the island of Vaxholm, just outside the capital, Stockholm. Vasa was meant to serve as a symbol of Sweden’s military might at the time but capsized after sailing just over 1,000 metres. It was salvaged in 1961 and is on display at the Vasa Museum in Stockholm, one of Sweden’s most popular tourist spots.
There are many ways you can review a dive computer, but wearing it on your arm for one or two dives does not constitute a proper test—at least, not a meaningful one. This review is therefore based on the use of the unit over a six-month period, where around 65 dives were conducted in different locations and water conditions. Lelle Malmström puts the Ratio’s new dive computer iX3M 2 through its paces.
The lack of proper O-ring care and preparation are two of the main causes of camera housing leaks. Underwater photo pro and photography instructor Kate Jonker offers advice and tips to help avoid these problems, keeping your housing (and hence, your camera) in good shape.
