Oceanic Geo 2

The Oceanic Geo 2 is a great entry level wrist mounted computer. So stylish you could wear it in and out of the water. The wide selection of colours will allow you to match your outfit whether it be on a tropical beach or penetrating a wreck at 30 metres under torch light. A simplistic menu orientation and 4 buttons allow for ease of use. Capable of adjusting for enriched air levels right up to 100% O2 with separate gas mixes. For the first-time dive computer buyers, not being restricted to where the high-pressure hose can reach gives you an unfamiliar feeling of freedom.

The display itself is simple and easy to understand (paired with a lovely laminated instruction for use card). Getting in the water needs no effort aside from securely attaching it to your wrist. (or leg we won’t judge you for it.) Whilst in the water, reading the display is very straight forward, everything important is right in front of my eyes. My depth, bottom time, no decompression limit, ascent rate meter and tissue loading graph. Probably my favourite thing is not having to scroll through the entire list of dives or options like those single button operation computers. If I just happen to miss what I’m looking for because I hit the button one time too many I can scroll backwards! Get rid of the console computer and your old G-Shock at the same time and purchase one of these gems.

Features Include:

• The Geo 2.0 Dive Computer is powered by Oceanic’s Exclusive Dual Algorithm™ – Your choice between Pelagic DSAT (Spencer/Powell data basis) or Pelagic Z+ (Buhlmann ZHL-16C data basis)

Desirable Dive Buddies have many important qualities, of course there is the fun factor, but really the reason for a dive buddy is simple – Safety!

Finding the right person to share the adventure of diving with can make a huge difference to your experience. Learning to be a good diver should include learning to be a good buddy diver too, however too often it seems the more experienced a diver becomes, the more they forget some of the fundamentals of diving safely and considerately with your dive buddy. Do you still remember to do a Buddy Check?  Dive your Plan and Plan your Dive? How about doing a dive brief and a de-brief?

One of the best ways to find a good dive buddy is to be a good one in the first place!  Another tip is to consider how they behavior out of water, and you should get a picture of what kind of dive buddy they will be!

Want to Meet New Dive Buddies?
Joining onto a dive trip, or enrolling in a dive course are some of the best ways to meet a dive buddy. Enquire with Dive HQ Christchurch for trips to Akaroa Peninsula, Kaikoura, Motenau, as well as the Solomons in 2018!

The Best Buddies are:

Patient – Are they a patient person, or do they hurry through tasks and take short cuts.  Will they wait for you if you have a problem or will they make you feel rushed? Diving with someone who tells you to hurry up, can lead to stress and mistakes.
Aware – Are they aware of their environment and others? Will they be able to spot dangers, or attractions and avoid getting lost.  Will they be aware of you, or will they ignore you under the water and go into their own world!
Positive  – What attitude do they bring to your dive? Are the positive and do they enjoy diving, will they be enthused about similar things to you and want to share in the enjoyment.
Good Communicators – Do they take the time to talk about the dive plan with you, and plan who will lead, or will you dive side by side. Do you plan what you will do if you lose each other?
Respectful – Are they a respectful person, to others and to their environment?  Or do they only think of their own needs, and do as they please during a dive rather than consider you and the surroundings.

Buddies to Beware of:

Buddies who won’t do a buddy check!
Buddies that go down or surface without you!
Buddies that don’t dive to plan.
Buddies that don’t dive close to you
Buddies that get into underwater arguments!

Why Bother with a Buddy?

Aside from the enjoyment of sharing the dive experience with someone, there are a number of scenarios where you would count your lucky star fish that you have a buddy to help, including:

Worst case – Out-of-air emergency
Low on air
Getting trapped in ropes/seaweed/net
Equipment failure
Illness or medical emergency
Getting caught in a current
Leg cramps
Getting lost
Feeling narked and making poor decisions
Feeling panicked

HAVE YOU EVER?

Lost your dive buddy while taking photos or spearfishing?
Had cramp in your leg while diving, but had no one to massage it for you?
Surfaced without your buddy?
Started a dive without doing a buddy check?
Spent a whole dive chasing your buddy’s fins just to keep up with them?
Forgotten to turn on your tank – clear sign of forgetting the buddy check!
Come to the surface after a dive and found only one of you saw lots of cool stuff while the other missed it?
Had an underwater argument?
Felt that your buddy has put your safety at risk while diving?

Let’s keep the Dive Buddy standard a high one and enjoy safe diving together.

Waking up in the morning to leave for a job that you love is everyone’s dream. Not dragging your feet, no dreading feeling in your stomach – they say that ‘he who loves his job never works a day in his life’ and I’d say I would have to agree. However, finding a job that you are passionate about, and can remain so, can be a bit of a challenge.

It seems that jobs such as diving instructor, ski instructor, crewing on yachts, and working for the likes of Lego, Google etc. are often classified as ‘dream jobs’. I would say any arrangement that combines your favourite hobby with a profession could be said to be a dream job. But maybe we can broaden our horizons and think even more outside the box? If it is a career in diving that interests you, there are more opportunities out there than you might think!

Obviously there are the jobs that spring to mind immediately, such as underwater photographer and commercial diver, however whatever your interest may be, there is a subject for it: marine life, education, construction, conservation… Here are a few of the wackiest ones for you to choose from:

1. Underwater Pizza Delivery Boy

Yup, you read that right. There is an underwater lodge in Florida – a converted research lab – where the services include a delivery service! It is not uncommon for guests to request their dinner be delivered. The job involves collecting dinner (or whatever needs delivering) and placing it in an air-tight box, gearing up, and heading the 6.4m down to the air-lock hatch situated under the lodge. Voila! That’s one deep dish for you.

2. Marine Archaeologist

Are you interested in both history and science, along with a passion for diving and the ocean? Then maybe this is the job for you! Explore shipwrecks and lost underwater cities in order to gain a better understanding of the past. You need to have studied archaeology (duh) and be a proficient diver in order to land a job in the field… but if you do, you could end up doing some seriously awesome research, like scrutinizing the remains of pirate/privateer shipwrecks to establish more facts on their era!

3. Underwater Model

Looking amazing underwater definitely requires a significant amount of skill. You need to be relaxed, comfortable in the water, and constantly aware of your positioning to make it in the underwater model world. Although it does not require any specific qualifications to get started down this career path, being a qualified diver is a start. Getting in to freediving and breath hold is a plus, as you will need to be able to hold your breath without looking like a puffer-fish! If this is a profession that interests you, start practicing in a pool until you comfortable with your surroundings. Soon you could be posing as a mermaid/merman!

4. Underwater Criminal Investigator

A UCI diver is primarily trained in recovery, be it a bullet, gun, knife, body, or vehicle. Once they have located their target, there are steps to follow, ensuring that correct evidence handling and chain of custody procedures are adhered to – even though you are underwater! Conditions are almost always deep, cold, and in near to zero visibility making a career in underwater criminal investigating a challenging yet fascinating one.

Learn more by reading PADI’s interview with Public Safety Diver, Mike Berry.

5. Underwater film crew

Lots of movies involve submerged scenes. No matter where it is shot (unless it is 100% CGI) there will be divers involved; safety divers, underwater videographers, stunt divers, and models (see above). Regardless which aspect you are involved in, it would be an incredible way to partake in such a production. If you have an interest in the medias, and a love of the underwater world, you may well have found your niche. If this is something that interests you, PADI does an Underwater Videographer course.

There is a dream job out there for everyone, we just hope yours involves diving too! If you haven’t quite found the ideal career yet, keep honing your diving skills by working your way up through the courses, and expanding your knowledge base by enrolling on some PADI specialty courses!

We would love to hear about your dream job! Tell us all about it in the comments.

Are you a Safe Scuba Diver?
We hope so! One of the easiest ways to stay safe is to ensure your Scuba gear is in good working condition.  That means getting your BCD, Regulator, and Tanks serviced and tested regularly. If you periodically get your gear serviced, then you are already a winner in our books, but we would like to reward and encourage you even more…

Get your gear serviced or tanks tested this September and be in to WIN!

Get your equipment serviced and/or your tanks tested during the months of August and September and be in with a chance to win $150 valid in store*.

For every tank tested (hydro or visual), get your name in the draw once.

For every BCD fully serviced, get your name in the draw once.

For every Reg fully serviced, get your name in the draw twice!

One lucky winner will be drawn on Saturday 8^th October to win a $150 voucher valid in the Dive HQ Christchurch shop.

*Voucher valid for purchases in the Dive HQ shop – excludes trips and courses. Voucher valid for six months.

Why get your gear serviced?

Your Dive Gear is your underwater life support system, so please don’t let it fail you or your buddy when you need it the most! Over time, o-rings and seals can perish, hoses need pressure checking and potentially replacing. A good clean out of the insides of your gear is never a bad thing either!

Gear that is regularly serviced ensures you with a smooth, safe dive! It also means any potential problems can be picked up early to prevent an incident.

When to get your gear serviced?

Regulators – Annually, or every 6 – 12 months if you dive more than 100 dives a year, or as per the manufacturers recommendation.
BCDs – Annually – as with regs, it is best to get your BCD serviced every year, or more often if you are a very regular diver!
Tanks – Visual Test Every Year and HYDRO every second year. (Note: A Visual is also performed when you have a HYDRO test done)

What next?

If you would like to learn more about servicing, and what goes on inside your regs, you can become a PADI Equipment Specialist.

One of the most common issues for Divers is equalizing your ears.

There can be many reasons for this such as congestion due to a cold, swimmer’s ear, narrow Eustachian tubes, or other pre-existing issues and damage from barotrauma.

I have always had sensitive ears, and after suffering a barotrauma I worried that this would stop me diving, but after doing some research and trials at the deep end of the pool, I found an equalizing method that works for me.  I’ve compiled a list of tricks and tips, the first 4 are pre-dive and the rest apply to the dive itself.

Hopefully there’s one or a combination of tips that work for you, and remember don’t push it – there’s always next time.

Here are a few other tips, these are things to thing about before going diving:

• Avoid milk and other dairy products that may increase your mucus production.
• Avoid tobacco and alcohol: like dairy they can increase your mucus levels.
• Start clearing your ears early – even hours before you dive.
• Chew gum before diving, this keeps you swallowing which is opening your Eustachian tubes.

 Once you’re in the water think about these pointers:

• Equalise at the Surface – this can help you get down the first metre and can also inflate your Eustachian – remember, be gentle!
• Descend feet first – it can be much harder to clear with you head down.
• Look up as you descend. This stretches the tubes, I often stretch my neck from left to right as well to help extend the stretch.
• Use a descent line – this will help you control the speed of your descent.
• MOST IMPORTANTLY – STOP IF IT HURTS! Your Eustachian tubes have been blocked by the pressure differential. Ascend a metre or two and try equalising again gently.

Clearing Methods

The most common method is the Valsalva Manoeuvre – this is the most common method, you pinch you nose then blow gently. Be aware of how hard you are blowing as too much pressure could rupture an ear drum. Never blow for more than 5 seconds before taking a break. The problem with this method as it doesn’t open the Eustachian tubes, instead air is forced up into them but this won’t work if the tubes are already locked due to a pressure differential.

Another common one is the Toynbee Manoeuvre – you start with pinching your nose, and while holding it – swallow. The motion of swallowing opens the tubes while the movement of your tongue forces compressed air against them.

The Lowrey Manoeuver combines the Valsalva and Toynbee and this is one that works well for me. While holding your nose – blow gently and swallow at the same time.

The Frenzel Manoeuvre requires you pinching your nose and closing the back of your throat (as you would do when straining to lift something). Then try making the sound of the letter ‘K’, closing you throat is opening the Eustachian tubes and making the ‘K’ sound forces air against the opening.

The Edmonds Technique involves tensing the soft palate – this is the soft tissue at the back of the roof of your mouth – and your throat muscles, while pushing the jaw forward and down, do a Valsalva manoeuver.

This next one requires a bit more practice – Voluntary Tube Opening. Again start by tensing the muscles of the soft palate and throat while pushing your jaw forward and down as if you starting to yawn and this will pull the Eustachian tubes open. With a lot of practice some dives can learn to control these muscles and hold the tubes open for continuous equalization.

Do you struggle with equalizing? What methods work best for you? Share in the comments below!

With winter now upon us, the air temperature has started to drop and the ski fields are finally open. Most of you have probably hung up your dive gear for the season and swapped it for a nice warm fire place, or a jacket and beanie when you dare to head out and about. The water is definitely getting chilly – I will not argue with that, but it could be a lot colder… Imagine if you were diving in somewhere like Iceland, in the Silfra fissure where the water is a freezing 2-4 degrees all year round. You would be crazy to do this without a dry suit.

The Silfra is known as one of the top dive sites in the world because of its crystal clear water and the crack in which you are diving. When you head down into the water you are between two continental plates; the North American plate and Eurasian plate. The water visibility between these two plates can be up to 100m, as clear as drinking water. The water comes from the Langjokull glacier and is then filtered through the ground for up to 100 years until it reaches the Thingvellir Lake. There is not a lot of life in this ravine other than trout, but it is beautiful none the less. The rock walls at some points almost meet, and you can touch both sides on the plates. There is a crazy green algae that grows on the bottom which they call ‘troll hair’. This UNESCO world heritage site is unlike anything you will have seen before.

So the next time you are thinking it’s too cold to go diving in New Zealand, remember it is about 10 degrees at the moment and that there are a lot of colder places in the world where you could be getting in the water! Also, some of the best diving around the South Island can be done over winter. The weather normally calms down and we get a constant Southerly swell rolling through. Think of all those amazing dive sites on the North side of Akaroa or Kaikoura that you missed out on diving over summer and do them now!

Remember we are having a Drysuit Demo Day on Saturday 30th July, so if you want to experience the toasty warmth of drysuit diving, let us know!

Give us a call on (03) 379 5804, or email us at sales@diveskiworld.co.nz. You can find us from Monday to Saturday, 8:30am until 5pm at Dive HQ Christchurch, 103 Durham St South!

As winter draws nearer, it is time to start preparing for the cold. Bring out the woolly jumpers, stock up on hot chocolate, (and don’t forget the whisky!) Shorter days, chilly weather, and cooler waters are no reasons to stop you from diving – so long as you know how to keep warm.

It is important to remember that you lose heat 20 times faster in the water compared to on land. Although 16°C may feel comfortable when you are dry, you will quickly feel the cold on a dive.

So how should you keep warm this winter? Here are a few pointers to keep you diving throughout the upcoming months:

Keep your head covered:

Your head is one of your main points of heat loss; in the same way you would wear a hat and scarf when it is cold, wear a hood when diving! With 20 to 40% of heat lost from your head, keeping it covered makes a significant amount of difference when trying to stay warm. If your wetsuit doesn’t have an integrated hood, you can buy them independently (we stock several different models here at Dive HQ Christchurch).

I know that the idea of a hood can be off-putting, and is disliked by many, but there are simple steps to follow to avoid discomfort:

• Keep your hood down and your wetsuit slightly unzipped until you are ready to enter the water
• If you have a separate hood, put it on at the last minute
• Remove your hood during the surface interval, dry your head off, and if possible put a dry hat on

Layer up:

So you have a 7mm wetsuit to keep you nice and warm, yet the chill is still getting through… Why not add a layer under your suit? The same goes for a drysuit. There is nothing to stop you wearing thermals or a sharkskin under your suit.

A great option is Oceanic’s Lavacore range. An awesome selection of thermals: tops – hooded or not, vests, shorts, pants, suits, caps, gloves… Why not try out the Elite merino lined range to guarantee warmth and comfort this winter! Not only are these great under your wetsuit or drysuit, you can use them for many other activities too. Wear them kayaking, sailing, skiing, surfing… a purchase you definitely will not regret! Pop into Dive HQ at 103 Durham St South to find the perfect Lavacore for you. We are continuing to sell all Lavacore at their sale prices. 25% off the standard range, and 30% off the elite range! 

Toasty toes:

No doubt about it, as the temperature drops you become more reluctant to don a wetsuit and take the plunge. There is nothing worse than frozen fingers and toes (ok, I exaggerate – they won’t quite freeze). Want some tricks of the trade on how to keep your extremities warm? You’ve come to the right place. You will already have gloves and boots, but are you wearing anything under them? No? Well you should be! Buy some disposable latex gloves to wear under your neoprene gloves – the trapped air will help keep you warm! Wear a pair of non-cotton socks inside your boots to keep those little piggies toasty warm even on the coldest of days.

Dry suit diving:

Opt for the warmest option of them all! Come and talk to us about our drysuit range. We can help you find the perfect drysuit for you, and talk you through the advantages of owning one, as well as taking you on a drysuit orientation dive.

Prepare for your surface interval:

If you are doing multiple dives, you want to make sure you have everything you need for your surface interval. Have a flask of something hot ready – tea, coffee, soup is a great one, and something warm to put on. Having a windproof jacket to hand is a good idea, as you can pull it on even over a wetsuit and escape from the chilly breeze.

Just remember not to rush your surface interval in your eagerness to return to the water on cold days! Safety first!

Take a break:

If it all gets a bit too much and you need to escape to the sunshine and do some diving in more temperate waters, get in touch with us about our upcoming trips. We are off to the Solomon’s in June, and Fiji in August. Feel free to ring or email us for more information!

Come and see us at Dive HQ for more tips and pointers on staying warm to keep you diving this winter!

What is Nitrox?

Nitrox is short for Enriched Air Nitrox, or EAN.  EAN when a scuba cylinder has been filled with a mixture of breathing air containing higher than 21 percent oxygen.  32 percent oxygen is the most common Nitrox mix.

Who should take this course?

The PADI Enriched Air Diver course is PADI’s most popular specialty scuba course. Why? Because scuba diving with enriched air nitrox gives you more no decompression time, especially on repetitive scuba dives. If staying down longer and getting back in the water sooner sounds appealing, then don’t hesitate to become an enriched air diver.

If you’re a PADI (Junior) Open Water Diver who is at least 12 years old, you can enroll in the Enriched Air Diver Specialty course.

What will you learn?

You’ll learn why diving with air that has higher oxygen and lower nitrogen content gives you more bottom time, along with enriched air equipment considerations. During a practical session, and two optional (or required) scuba dives, you’ll:

• Discuss managing oxygen exposure.
• Practice analyzing oxygen content in your scuba tank.
• Set your dive computer for diving with enriched air Nitrox.
• 

Benefits of Diving with Nitrox

By increasing the amount of oxygen in the air you are breathing, you are reducing the amount of nitrogen.  As divers are aware, they need to be aware of the build up of nitrogen in their body and prevent it from forming bubbles in the tissues as they ascend, which can cause Decompression Sickness.
