Reviewing Equipment

Design criteria

Not all equipment are created equal but for different purposes and users. Consider the two iconic German cars below.

Which one is the best, which one is the better design?

The Mercedes with its advanced technology, high performance and superior handling? Or the rugged and uncomplicated VW Beetle of which more that 21 million were sold and is the longest-running and most-manufactured car ever made?

Fish learn to stay within marine reserves–where it's safe

Researchers at the University of British Columbia (UBC) discovered that some fish have learnt to stay within marine reserves where they are safe from fishing, demonstrating the importance of such facilities. They made the discovery after modelling the movements of skipjack and bluefin tuna and great white sharks in the ocean.

Personal Safety at Sea: Communicating with the Dive Boat

One of the things close to everyone’s thoughts is diver safety. We spend good money on quality dive gear and prudently have it frequently serviced and maintained, as this equipment will be sustaining our lives while underwater. But what about when we are on the surface? Just how many of us really do think about getting lost at sea?

Great Hammerhead Sharks of South Bimini

Like a fashion model up on the catwalk, great hammerhead sharks sashay into one’s field of vision, and, if they were human, you would probably say they have just “made an entrance”. Their strange mallet-like head, robust body girth and tall sickle-shaped dorsal fin make them well-nigh instantly recognisable, and most other sharks in the immediate area spot that too and give them a wide berth.

Peak season for the SEABOB

Whether as enjoyment at the beach or adventuresome change on a yacht – the Seabob offers plenty of fun in the water. Thanks to the simple and intuitive operation through two control grips, anyone can start riding a Seabob right away and can cruise through the water at 20km/h. While you glide along noiselessly, you can also explore the world underwater with this high-performance sea toy.

Suunto Wireless Tank Pressure Transmitters

Suunto Product Recall

The Finnish manufacturer has identified a potential safety risk affecting all Suunto Wireless Tank Pressure Transmitters and Suunto Tank PODs that wirelessly transmit cylinder pressure to compatible Suunto dive computers.

In two reported incidents the exterior case of a Suunto Wireless Tank Pressure Transmitter has failed during regular dry land pressure testing. Although extremely rare, there is the potential for injury because of the risk of bursting.

Three-dimensional models of the American alligator's skull were developed using cutting-edge imaging and computational tools.

3-D models of alligator skull developed

Studying the origins and movement of animals often requires the presence of live animals. However, this is not always possible (in the case of extinct species), safe or practical. In such cases, scientists now have another option: developing three-dimensional models of the animal.

This is what the researchers at the University of Missouri (MU) and the University of Southern Indiana have done. Using cutting-edge imaging and computational tools, they have developed three-dimensional models of the skull of the American alligator.

Aircraft Wrecks of Papua New Guinea

World War II came to the Australian territory of Papua New Guinea in January 1942 when the Imperial Japanese Army invaded Rabaul in New Britain, followed shortly after by the taking of Kavieng in New Ireland. The invasion turned Papua New Guinea into a major theatre of war in the battle for the Pacific, and there were many brutal encounters between the invading Japanese and the defending Allied forces.
