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.

Conservation, sustainability and community are three words that Lembeh Resort in North Sulawesi, Indonesia has always been passionate about. Over the years, the resort has taken measures to reduce their plastic waste and become more environmentally sustainable in all of their operations, but this has now been taken to another level by a team of Lembeh Resort staff that founded the Lembeh Foundation. The Lembeh Foundation is an independent registered Indonesian charitable organization that is working along side local communities on Lembeh Island to provide environmental and economically sustainable solutions to waste management. The core aims of the Lembeh Foundation are to reduce plastic waste, and provide education and economic benefits while improving the health and sustainability of local communities.

“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
