Last issue I looked at the advantages of a small inflatable which could be put out of sight at home in a cupboard and yet easily transported to the water in the boot of the car. This issue I thought we would take a look at what its big brothers have to offer and their advantages for divers. more
Fossils, Caves, Copper and its 'Ruddy Gore'
By Keith Cardwell
It's all so exciting.
An outback town formed millions of years ago with fossilised coral reef
and mega fauna, cave systems to match the best, relics of earlier
industrial years in abundance, friendly locals with a pub to match and
birdlife to stun twitchers. Then there's Ruddy Gore and the mysteries it
still has to give up.
But then talk to any of the local cavers and ...

This is a dive I've looked at for years and it wasn't until we had Eric Simmons up from Nelson for a talk at our club, that I had looked at doing it again. The hard part was convincing Nikki that it was a good idea, especially driving all the way down from Tauranga...
Long strands of giant bull kelp swirl away from the rocks, then flick back. Beneath them, wider strands of Chatham Islands bull kelp do the same. There is no gap to jump into, but on the next surge the kelp opens and I slide into the water. It is cool at around 12˚C but not as cool as anticipated. more
The South Pacific has a way about her. She slowly seduces your body by caressing your skin with her warmth, and unclutters your mind with sparkling images of golden sand and shady palms. Her seduction starts the moment you board Polynesian Airlines’ Boeing 737 outward bound for one of her treasures floating on a turquoise sea. more

- Should I Dive Whilst Pregnant?
by Marguerite St Leger Dowse
There will always be women who dive not knowing they are pregnant, or
deliberately choose to dive whilst pregnant. With most medical
recommendations concerning women in recreational diving based on the
physiology of fit young men and animals, how do we determine safe
limits to dive whilst pregnant?
In other words ... optical help for divers having trouble reading their computers, gauges, and digital screens.

Even divers get middle aged, and one of the biggest nuisances from this stage of life on is the difficulty most of us suffer trying to read and see things that are close up. This includes reading our dive computer and gauges. The phenomenon of reduced ability to focus the eyes is called presbyopia, and I argue that it is a sign of maturity. more

Ross is a dear old chap, forever smiling and full of stories. He’s a big fellow tall, lean and remarkably fit for a man in his late 70s - and has been a guiding light in Nelson’s diving scene since it first began in the late 1950s. And even before that he was involved in the exciting early days of scuba and snorkelling in New Zealand. more
They say it’s a sure sign of old age when you start writing your memoirs! I catch up with Dive New Zealand occasionally, and with the plethora of new dive gear and methods available I thought it would be good to put on record where us old buggers have come from, before it’s too late. more
Divers who are into fishing will always have a huge advantage over the average fisherman. When you spend so much time underwater looking for your food (eg crayfish) you become more aware of the area’s structure, the types of kelp cover and the amount food there. This will, to a large degree, indicate what type and numbers of fish the area will hold. more
Having travelled a fair bit of the world I often stop and look around New Zealand’s coast and think how lucky we are to live in such a great country. Everything to do with the water is so close and achievable to all and you don’t have to have a big ‘flash Harry’ boat to enjoy it. more
What Causes Freediver Blackout?
by Julie Richardson
Simplified, freediver blackout is the result of oxygen starvation at the
end of a breath-hold dive. As a diver descends to depth the increasing
water pressure causes an increase in overall oxygen pressure, even as
oxygen is being consumed.
However, during ascent with water pressure and
oxygen pressure decreasing, and oxygen supplies running low at the end
of the dive, blackout can come on quickly with little or no warning.
The diver will experience ...
A chain lay out along the footpath stretching to over 60 metres; plastic tags fixed to the chain indicated the length beneath a large inflated inner-tube that the chain was fixed to. The tags started off at 10m and descended in 5m increments until the last tag boldly shouted 60m! more

It was in 1994 when Adobe introduced layers into Photoshop 3.0 - and a whole new world of artistic freedom and design possibilities has opened up. Today, 14 years later, it is difficult to imagine working in Photoshop without layers. The concept is simple, so simple indeed that it is covered in any beginner’s course. It is like having a stack of papers, each sheet with its own image. We look at the top sheet, but we can make individual layers invisible, change the order or reduce the opacity, making the layer more or less transparent. more

3rd annual Lake Taupo Catfish Cull

New Zealand's Lake Taupo Catfish Cull is now a firm fixture on the
annual diving calendar. Coming a week after the National Spearfishing

for serious, and many not so serious spearos to get together for the
novelty of spearing fish in fresh water, and along the way having a
positive impact on the lake's ecosystem ...

Interest in the sinking of the RMS Titanic on 15 April 1912 has endured
for 100 years. The accident remains one of peacetime's worst maritime
disasters, capturing the imagination of generations like no other. The
tragic events of that fateful April night continue to affect our lives
today and will generate interest for another 100 years.
The Olympic-class Royal Mail Ship Titanic was owned by the White Star
Line and built at the Harland and Wolff shipyard in Belfast, Ireland,
