  • Sexy Gas – What makes it so sexy?  

    Love diving? Want to stay under the water for longer? We have something to help.

    Today, we’re talking about Sexy Gas. That’s right, Sexy Gas!

    What is Sexy Gas?

    Nitrox or enriched air, or Sexy Gas (as we like to call it), is air enriched with oxygen which reduces your exposure to nitrogen whilst diving – it’s most commonly used by recreational divers. Sexy Gas has become so common and popular in fact, that you can almost always spot the green and yellow tanks of nitrox or enriched air in the ocean, on boats and in dive shops all over the world.

    So, what makes Sexy Gas different? Specifically, our banked Sexy Gas has 32% oxygen and 68% nitrogen.

    Why this composition? Put simply, nitrogen limits time at depth. So, the more oxygen in the breathing gas, the less nitrogen, and the longer time we have to spend diving.

    The sweet spot for diving with Sexy Gas is between 12 and 34 metres. This is where you can take maximum advantage of your increased bottom time – Now that’s sexy.

     

    Why use Sexy Gas?

    There are many reasons to use Sexy Gas.

    Here are just some of the reasons:

    • Allows for longer bottom times
    • Increased no-decompression time
    • Longer repetitive dive times
    • Shorter surface intervals
    • Less nitrogen exposure
    • Not much more expensive than simple compressed air
    • Reduces your relative risk of decompression sickness
    • Ideal for diving at shallower depths
    • Many divers have reported feeling less fatigued after the dives
    • The world’s most popular speciality diving course is Nitrox or Enriched Air

     

    Are there any Sexy Gas Myths?

    Yep! Like most things, there are some common myths about Sexy Gas.

    Here are a few:

    • It improves your breathing rates
    • It’s only used by technical divers
    • It’s perfect for deep diving
    • It improves your gas consumption

     

    Does Sexy Gas come with any risks?

    Whilst there are many benefits to using nitrox or enriched air, it comes with risks, like any type of diving air does.

    While we need it to live, too much oxygen exposure can be harmful to the body – this is referred to as oxygen toxicity. Cylinders containing Nitrox need to be clearly stickered and identified so that divers who are not familiar with the hazards of oxygen toxicity do not accidentally use enriched air.

    These are the reasons why you can’t just purchase some nitrox or enriched air at the shop and go off on a dive – Like all diving, special certification is required.

     

    How do you become an Enriched Air Diver?

    To dive with enriched air, you must first become a certified enriched air diver.

    With the PADI Enriched Air Diver course you will gain certification, enabling you to maximise your time underwater.

    The course only takes approximately 2 hours in the classroom to complete. You can study your materials at home, then come in to go through your knowledge review and take the exam. We'll show you how to analyse your enriched air cylinders and set your computer for diving with enriched air.

    At Dolphin Scuba, we have a range of courses and products available to help you become the best diver you can be. Come visit us today.

  • Plastic is NOT fantastic

    Plastic is killing our oceans – here’s how you can help!

    Whether we like to admit it or not, plastic is a huge part of our everyday lives.

    In fact, Professor Andrew Holmes, an emeritus professor at the University of Melbourne, said that “No-one in their daily life within a period of 10 minutes isn’t touching something that is made of plastic.” Wow! Isn’t that astounding? It’s safe to say we probably use plastic more than we realise.

    Let’s face it, we need plastic and it’s in a lot of everyday items. Disposing of plastic and how we do so, however, is a completely different story and has become a major environmental issue in our world today. To help you put it into perspective, according to a report by the World Economic Forum, if we continue on the current track we are on, by 2050 there will be more plastic in our oceans than fishes – Now if this isn’t heartbreaking, we don’t know what is.

    So, how exactly is plastic killing our oceans and what can we do about it? Let’s find out.

     

    How is plastic killing our oceans?

    Plastic in the ocean jeopardises the natural ambience of marine life in many ways. From disrupting the bio-geo cycle, causing unwanted problems to the entire marine eco-system to consumption of plastic by marine creatures, causing intestinal injury or even death.

    Among others, sea turtles are the most common victim of ‘Ghost Nets’ in the ocean. This is the term used for stray plastic nets used for fishing and plastic crates harming the marine life by choking them, or causing them to become severely tangled.

    Plastic in the ocean also threatens birds that depend on oceanic life-forms for their food. In most cases, birds suffer due to ingestion of plastic or suffocation.

    It’s not just the marine life being harmed by plastic in our oceans either… Fishes infected with such harmful substances from plastic might find their way into our household, thereby causing health problems to the end consumers too – Plastic and its toxins don’t discriminate.

      

    How can you help?

    Have these alarming and heartbreaking facts inspired you to do something to help?

    Here are some of the many ways you can: 

    • Say no to single-use plastic
    • Recycle (properly)
    • Participate in beach clean ups
    • Use fewer plastic products
    • Buy ocean friendly products
    • Spread the word
    • Steer clear of products with microbeads
    • Support marine conservation education
    • Buy sustainable seafood
    • Buy a reusable water bottles and coffee cups
    • Ditch plastic straws

      

    What does Dolphin Scuba do to help?

    You may be thinking, “Dolphin Scuba are telling us how we can help, but how do they?!”

    We are more passionate about our oceans than anything else – It’s why we do what we do. Which is why we do everything we can to help get our oceans back to beautiful, as they should be and we do all of the above and more.

     

    Here are just some of the ways we love to play our part in store:

    • We do not use plastic bags
    • We’re always putting the pressure on our suppliers to stop using single use plastic
    • You won’t see any high glossy brochures in our store - Our printing is done on recycled paper with black ink only!
    • We recycle all our batteries
    • Single use plastic is reused wherever and whenever we can

    As you can see, plastic really is killing our oceans and it’s only going to get worse, unless we all play our part to help save it.

    Are you ready to start helping save our oceans?

    At Dolphin Scuba, with the help of the Fourth Element Ocean Positive Program, we’re now selling reusable water bottles and coffee cups. So, why not start by purchasing a reusable water bottle or coffee cup? Or better yet, why not both? Pop in the store to say hello and grab yours today!

  • 4 Reasons to Advance Your Diving Skills

    Now that you’re an open water diver, regularly exploring under the sea, you may be thinking “Why would I need to do anymore training? I’m done!”

    You may be happy with the dives that you can do, be feeling confident and comfortable and not interested in furthering your diving skills and that’s okay. But if you do however find yourself thinking about certain diving spots that may be out of your reach, or dreaming of diving that little bit deeper, then perhaps further dive training is something you should consider.

    We share 4 reasons to consider advancing your diving skills.

    1: Go deeper into discovery

    As an open water diver, you can only dive as deep as 18 metres. Many ship wrecks, sea creatures and fascinating findings beneath the deep blue sea, are actually found deeper than that.

    As an advanced open water diver, you will have the freedom to dive as deep as 30 metres (close to double the depth you could before), giving you the opportunity to discover double the sea treasure!

    2: Feel more comfortable

    You may be feeling fairly comfortable diving already, but there is also room to feel even more comfortable and why wouldn’t you want that?

    During the PADI Advanced Open Water certification course, you will be taught more skills, helping you to feel comfortable diving in a variety of environments.

    And from comfortable, come enjoyment, so you can enjoy your diving experience even more than you already do – yes, that’s possible!

    3: Get close to shipwrecks

    Most of the world’s dive-able wrecks lie below 18m. As such, if you’re keen to explore more wrecks, you should complete the advanced course and choose the Wreck Diver as one of your specialist dives.

    Did you know that Western Australia is full of more breathtakingly beautiful dive destinations than you probably even know about?

    Just two of the wonderful wrecks you can explore off the coast of WA:

    • HMAS Swan Wreck – Dunsborough

      Dunsborough is the final resting place of the former Australian navy destroyer, HMAS Swan. It was sunk purposely for divers in 1997 and now lies in 35 metres of water in Geographe Bay, off Dunsborough. The ship has since become home to many fish species and beautiful coral. 

    Divers have also been said to dive in dozens of time, and yet still manage to always find something new.

    • Key Biscayne Oil Rig Wreck – Lancelin

    Key Biscayne is a deep dive a long way off the coast. Located 120 minutes off the coast of Lancelin the Key Biscayne wreck has an average depth of 25 metres and maximum depth of 44 metres. The ship sank in 1982 while being towed to Perth for modifications.

    There are a few dive shops that run the occasional trip out there but you need great weather and almost no swell. She rests in 44m but the wreck starts at about 25m.

    4: Explore the world

    Because the advanced open water diver course allows you to become just that - ‘an advanced open water diver’, you will have the skills and confidence to explore more of the world.

    With additional skills such as navigation, improved breathing and buoyancy control, as well as increased understanding of the use of diving gear, you will become more confident than ever to dive in the many unique and exciting dive spots all over the world.

    If you’ve ever dreamed of certain diving spots that may be out of your reach, or diving that little bit deeper, then further dive training is for you.

    You don’t have to be advanced to do the PADI Advanced Open Water Diver course either. The course is simply designed to advance YOU.

  • PSA: Don’t pollute to keep our oceans beaut!

    At Dolphin Scuba, we are true blue ocean lovers – that’s one of the biggest reasons why our team is made up of experienced scuba divers. Having a scuba diving qualification means you are able to go out and explore the wonders of the deep. However, there’s one big thing that landlubbers are doing that could jeopardise our beautiful oceans - pollution.
  • Scuba dive holiday locations in the Asia-Pacific  

    During the cooler dive season, it can be a little harder to get out into the water. Despite this, the ocean is arguably even better for scuba diving due to the clearer water conditions and the abundance of new marine life not seen during the warmer season. Australia is located in the Asia-Pacific region, meaning warmer water conditions are only a short flight away. If you want to keep diving during the winter season, without the cooler weather conditions – perhaps it’s time to plan your next dive holiday.
