Hammerhead 01

Although great hammerhead sharks (Sphyrna mokarran) appear powerful and robust, recent research has shown that they are in fact one of the most fragile shark species, being particularly vulnerable to the stress of capture. Even those that are released after being hooked have a nearly 50% chance of succumbing after their ordeal.1 To better protect these sharks, a greater understanding of their movements is needed. The results of a new study conducted by scientists at the Bimini Biological Field Station in Bimini, Bahamas have provided a major step forward by showing the migration patterns and regional connectivity of great hammerheads between the Bahamas and the United States.

The beautiful island of Bangka sits in the heart of the Coral Triangle in Indonesia. Its white sand beaches, crystal clear water, endemic species, traditional way of life and phenomenal coral reefs make it an idyllic diving destination. But for 8 years it has been threatened by corruption and illegal mining, which has left forest areas damaged, mangroves destroyed, islanders distressed and the diving community angered.

Shootout

The SHOOTOUT, which will be held from 15 to 23 June 2018, will again pitch two teams head to head in a live underwater photography contest.  A team from the beautiful Gulen Dive Resort (http://www.gulendiveresort.com) in Norway will be competing with their opposing team at the equally beautiful Lembeh Resort (http://www.lembehresort.com) in Indonesia. The first contest, in 2016, resulted in the narrowest of last-minute victories for the team from Lembeh.

If scuba diving is the adventure sport they do in Heaven, then fish watching is one of its great highlights. Diver heaven is right here on Earth at Komodo Marine Park. Her reefs have colours of every hue bursting brightly in profusion in the brilliant life-giving sunshine.  It has an abundance of fish, and much of the rocky surface is covered in hot pink soft coral and red sponges, making a beautiful backdrop for these fish.

“Bubbles Away”- Oceanic Omega 3 Review

Thursday, 22 September 2016 02:37

By Brett Lobwein

 

The Oceanic Omega 3 side exhaust regulator is the perfect choice for underwater photographers, videographers or SCUBA divers who want to avoid any distraction from focusing on the ocean. Apart from the exhaust [flow] bubbles being directed away from my face, as a photographer I really like the Omega 3’s profile. Being a side exhaust means there is not a bulky regulator pushing up against the back of the camera housing as you look through the viewfinder.

The biggest ‘upgrade” of the Omega 3 over the very popular Omega 2 is that it no longer breathes wet. It comes packaged out of the box with a MaxFlex hose* and a ball swivel, making it very comfortable plus dramatically reducing the regulator pulling against your jaw. Tech divers will also love that this regulator is ambidextrous “no up or down”, making it an ideal choice for a side mount setup.

I have managed to test the Omega 3 to a depth of 52 metres (170 feet). The entire way from the surface to 52 metres the Omega 3 delivered the perfect amount of air without the need for any complicated adjustment knobs. A simple twist operated dive/pre-dive switch is very handy to stop any free flowing on the surface.

Oceanic has paired the Omega 3 with the lightweight and top-performing FDX-i first stage. For those who want to explore colder oceanic waters, the FDX-i is ready with an environmentally sealed diaphragm. As you would expect this first stage is also balanced, which ensures the regulator performs consistently at any depth. I have also been very impressed with the well thought out port layout and positioning. The FDX-i uses Oceanic’s Dry Valve Technology (DVT) preventing water or other foreign objects from entering the first stage, ideal if you forget to put the dust cap on.

Complimenting its modern design, the Omega 3 comes in three colour choices—black, white or clear. Personally I love the clear, as it allows you to see the beautifully engineered internal workings of the second stage. After owning the Omega 3 for over 12 months, I am still blown away by its performance.

*Check with your local dealer that this is standard in your location
