Intro to Tech: What is it about?
Article by José Pablo Mir
Pictures by Cezary Abramowski
The world of technical diving is exciting. It opens the door to new sites, depths, and bottom times. More importantly, it opens our minds to a new way of planning, facing, and experiencing dives, even those not purely technical.
Becoming a technical diver is a process, and like in other aspects of life, we should find the proper entry point that suits us best based on our knowledge and experience. The Introduction to Technical Diving course from TDI -the world’s largest and most recognized technical diving teaching organization- is the best option for divers who have yet to gain experience in the fundamental aspects of this new practice. The course’s content and its embrace of new techniques and technologies make it possible to acquire a solid foundation to learn and gain experience in this practice properly.
Becoming a technical diver is not something that happens overnight, whether deciding to become one or receiving a certification card stating we are now technical divers. It is a slow process extending farther away than any introductory course. It requires effort and dedication. But it will bring us satisfaction from day one -or two.
It is a matter of mentality
First, we must understand and accept that technical diving, involving greater depths, longer bottom times, exotic gases, virtual or real ceilings, and more, comes with higher levels of risk than the sport diving we have been practicing until now.
Although this discussion usually starts with a warning about risks, as I’ve done in the previous sentence, our practice is not a game of chance.
Technical diving is a rational activity that requires maturity and good judgment, and we will put everything into ensuring that each dive is a successful one -meaning we return from it safe and sound. With this understanding, we will strive to establish a mental attitude more aligned with our practice and its realities.
This new “technical diver” mindset we will develop will lead us to be more cautious in our executions, more analytical in our plans, more rational in our strategies, and more detailed in our procedures.
Experience will keep teaching us to know ourselves better, to keep our anxiety and other emotions under control, and to manage our impulses. Over time, our senses will sharpen, and we will be more attentive to the particulars of the situation we find ourselves in.
Strategies and procedures
Our strategies, those broad guiding lines tracing the path to follow, from how to approach planning to where, with what, and how we are willing to get there, will be more specific and more practical. Not because they magically become so, but because we will consciously and deliberately frame them that way.
We will establish clear, concise, and realistic procedures. Not only for the undesirable situations that may present themselves but also for those that are part of our dive objectives.
Even though, as technical divers, we often use equipment different from what we were previously accustomed to, it is essential to note that the gear does not make the diver. In a way, we could consider such equipment as the necessary tools to implement what our goal seeks to achieve, according to our strategies and procedures.
Technique plays an important role
We must put our greatest effort into learning and perfecting the different techniques we will be acquiring. Buoyancy, trim, propulsion, cylinder handling, deploying DSMBs and lift bags, valve drills, and more are essential skills we must begin to master to progress in our art. What we cannot do, when we need to do it, can harm us.
Our techniques must be effective and achieve the purpose for which they were devised. But they must also be efficient and require the least resources possible, including the time they take and the effort they demand. Effectiveness and efficiency will prevail over beauty and other considerations that may come to mind, although none of them should be mutually exclusive. A technique executed efficiently and effectively tends to have an inherent beauty.
Refining techniques is a lifelong mission. Some of them will be easy to master from the go; others, on the other hand, will be our life mission and will require many repetitions just to resemble the idea we have in mind of how they should be executed.
We must consider the environment
Our learning, the needs and musts of the practice we engage in, the experience we gradually gain, our strategies and procedures, and even our equipment and tools change with the environment.
Diving in the ocean, everything about us must be suitable for ocean dives. Conditions there rarely emulate those found in a pool, lake, or river. Variable winds and currents, greater depths, visibility conditions, other divers with uncertain skills around us, marine life, maritime traffic, distance from the coast, and many other factors add complexity and uncertainty.
It is never necessary to master the pool on the first day, but planning and aspiring to gradually cope with the ocean’s conditions is essential.
The cost of good training
We are aware that our resources are often scarce in relation to the possibilities of use we could give them if they were not. To a greater or lesser extent, we are part of the economic reality in which we are embedded.
Fortunately, the cost of good technical diver training is not an entry barrier. Comparing training and equipment costs, we see that the former are generally lower. Yes, lower cost for personalized service, essential to our future
performance and safety, than for a series of mass-produced products that are mere, albeit necessary, tools for an end.
The value of good training
The value of the training we received encompasses a range of characteristics, from emotional and methodological to technical and technological. TDI and its Introduction to Technical Diving course offer a deep and modern approach, with a teaching strategy that aims to create thinking divers, not merely obedient ones.
As technical divers, our knowledge is our primary tool. In this type of activity, what we don’t know can harm us.
Is this course optional?
Unfortunately, the fact that this Introduction to Technical Diving course is not a prerequisite for any subsequent training is an invitation to consider it optional. And we all know what usually happens to “optional” under budget constraints.
However, this course should be seen as optional only by those divers who are somehow familiar with the use of technical equipment, who have a mindset more in line with the requirements of this type of diving, who plan and execute the dives the proper “technical” way, who know their gas consumption rate, who are not intimidated by non-decompression tables, who feel comfortable using their dive computers, and know the techniques and have at least an acceptable level of buoyancy, positioning, and propulsion. Those can go straight to a more advanced training course, such as TDI’s Advanced Nitrox.
We must ask ourselves whether or not we are in that group.
Remember our goal: to have fun
Recreational diving is our passion. Jumping into the water carrying heavy equipment and having properly dotted our I’s and crossed our T’s have only one ultimate goal: fun. This is the activity we have chosen as a hobby. We must enjoy it; it must give us pleasure and make us vibrate.
Having a good time is not optional!
In this series, the Shark Trust will be sharing amazing facts about different species of sharks and what you can do to help protect them.
As we’re currently in butterfly season, this month we decided to concentrate on the Butterfly Rays!
Within the family Gymnuridae, there are two genera and 12 species of Butterfly Ray. These species are morphologically different to lots of other rays because of the width of the disc and pectoral fins – in contrast to many other species of Butterfly Ray, their bodies are much wider than they are long, especially considering their very short tail. This gives them the appearance of gliding or flying across the sand.
Gymnura altavela – Spiny Butterfly Ray
Gymnura australis – Australian Butterfly Ray
Gymnura crebripunctata – Longsnout Butterfly Ray
Gymnura japonica – Japanese Butterfly Ray
Gymnura lessae – Lessa’s Butterfly Ray
Gymnura marmorata – California Butterfly Ray
Gymnura micrura – Smooth Butterfly Ray
Gymnura natalensis – Backwater Butterfly Ray
Gymnura peocilura – Longtail Butterfly Ray
Gymnura sereti – Seret’s Butterfly Ray
Gymnura tentaculata – Tentacled Butterfly Ray
Gymnura zonura – Zonetail Butterfly Ray
Spiny Butterfly Ray, Gymnura altavela. Playa La Granadella, Spain, Mediterranean Sea.
Today we’re taking a look at Gymnura altavela, the Spiny Butterfly Ray. Like all Butterfly Rays, the Spiny Butterfly Ray is a demersal species, meaning it spends the majority of its time on the bottom of the seabed. Butterfly Rays are known for their burying behaviour in the sand, a technique they use to camouflage themselves when they are resting during the day. This protects them from predators, in some areas larger sharks. It also aids them in their ambush hunting technique – by hiding themselves under the sand they are able to easily snatch up their dinner – usually crustaceans, molluscs or other small fish – as they swim by unawares. This behaviour can leave tell-tale butterfly-ray shaped imprints in the bottom of the seabed.
Spiny Butterfly Rays can grow up to 260 cm (disc width (wingspan)), although average is around 200 cm. They give birth to live young, and each litter consists of 1-8 pups. This species has also been found to aggregate, likely for mating. One study found that aggregations of primarily females in the coastal regions off Gran Canaria may correlate with the shifting water temperature.
It is estimated that the species has undergone a population reduction of 50-79% over the last 33 years. This is primarily due to fishing pressure – the Spiny Butterfly Ray is targeted and bycaught in both industrial and artisanal fisheries types using a variety of gear types. The species is now Critically Endangered in the Mediterranean and Southwest Atlantic.
Scientific Name: Gymnura altavela
Family: Gymnuridae
Maximum Size: 260 cm (disc width)
Diet: crabs, shrimps, various invertebrates, fishes, small crustaceans, and molluscs.
Distribution: throughout the Atlantic and Mediterranean and Black Seas.
Habitat: muddy and sandy substrates down to 150m.
Conservation status: Critically Endangered in the Mediterranean and Europe, Endangered Globally.

RATHLIN ISLAND, NORTHERN ISLAND
Rathlin to the north of Ballycastle has some fantastic diving. The strong tidal currents in this area mean the marine life is numerous, varied, vibrant and healthy. The northwest cliffs drop to depths of 200m just offshore making an impressive wall dive. Tides hitting the cliffs can create powerful up and down currents, so experience and staying close to the rock is important, but well worth the effort. On the east coast the wreck of the S.S Lochgary, a converted government transport ship, which was involved in the WWII Dunkirk evacuation, before sinking in her current location in 1942.
Happy diving!!!
