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!

From its humble beginning in 1994 to today, the group of training agencies Scuba Diving International (SDI), Technical Diving International (TDI), and Emergency Response Diving International (ERDI) form one of the largest diving certification agencies in the World – International Training. With 24 Regional Offices servicing more than 100 countries, the company today far exceeds the original vision the founders had when they conceived the idea on a napkin, sitting at a kitchen table in the early 1990’s.

Alonissos: The complete diving destination (Part 1)

Published

on

In June we were incredibly fortunate to be invited to dive in Alonissos, a small Greek Island in the Sporades island chain located in the North Aegean Sea.  While I have long been a big fan of the Greek Islands as a great holiday destination, I had not had the opportunity to do any diving on previous visits and Mike and I were extremely excited to see what Alonissos had to offer both above and below the surface!

The Sporades are easily accessible via the airport in Skiathos (the first island in the chain), which is served by Jet2 flights from all major UK airports from May through October.  Numerous ferries and charter boats make island hopping from Skiathos Town a breeze.  After an hour boat ride, the picturesque port of Patitiri was a wonderful introduction to Alonissos, where we were met by our gracious hosts Kostas of Albedo Travel and Dias of Alonissos Triton Dive Center.  Mike and I were delighted to be staying at the Paradise Hotel, aptly named for its stunning views over the sea and great location for walking to the waterfront.

Alonissos is beautifully situated in the National Marine Park of Alonissos and the Northern Sporades, the largest marine protected area in Europe.  The surrounding seas offer fabulous marine life, including incredibly rare species such as the Mediterranean monk seal.  They boast deep walls covered in gorgonians and sponges, stunning topography with caverns, swimthroughs and pinnacles, and the first accessible ancient shipwreck from 500BC!

In locations where historical sites have been reported, the waters are largely restricted, but with collaboration between government, underwater archeologists and dive centres, incredible underwater museums are being created for a truly unique diving experience.  Alonissos is home to the first of these, the Ancient Shipwreck of Peristera Accessible Underwater Archeological Site.  The chance to dive into history (along with reports of healthy reef life and amazing underwater topography) meant Mike and I were keen to get in the water.

Our introduction to the diving around Alonissos was at the Agios Georgios Pinnacles, in the channel between Alonissos and Skopelos.  This fantastic site was named “The Chimney,’ and proved to have a huge amount to see.  We got to a decent depth here (over 25m), and marvelled at a colourful reef wall with a wonderful swim through whose rocky walls were absolutely covered with life.  As well as brilliant topography there was no shortage of macro life here.  We saw numerous nudibranchs, five different species in total.  The second dive at Mourtias reef nearby was a shallower dive along a nice wall with lots of crevices. Several moray eels and grouper called this site home.  We enjoyed looking in the crevices for lobster and smaller benthic life, such as cup corals and tunicates.

Our itinerary allowed us two dives a day with afternoons left to explore the island with our hire car and evenings to enjoy the famous Greek hospitality.  This proved to be a lovely mix of in-water and land based diversions.  

The next days diving to the Gorgonian Gardens and Triton’s Cave was to be even better!  These two stunning sites are nothing short of fabulous.  The Gorgonian Gardens was a deep wall near to the Agios Georgios islands.  The ever-present currents in this deep channel meant that the sea life was amazing … the namesake Gorgonian sea fans dotted the wall at a depth of 30 to 50 meters, getting ever larger the deeper we went.  Above 30m was by no means less beautiful, with sponges, corals, scorpionfish, moray eels and some rare and colourful nudibranchs.

The second shallower dive of the day was to Triton’s Cave or the Cavern of Skopelos, on the east side of that island. The spectacular rock formations had wild striations both above and below the water making a truly epic topography.  The cavern entrance was at 14m, and big enough for a buddy pair, winding up to 6m and passing two beautiful windows out into the blue.  Emerging from the cavern, the light at the shallower depths and the incredible rock formations made for a fantastic gentle swimming safety stop and we all surfaced by the boat with massive grins.

Mamma Mia! Diving Skopelos (Part 2)

Published

on

Our second days dive itinerary was to the famous Christoforos wreck! This is arguably the best dive in Skopelos and though only open to divers with deep diving experience, this 83m long wreck is well worth the visit.  

The Christoforos sits in 43 meters of water with the deck at 32 to 35 meters.  A 30m dive can give an impressive view of the wreck, though such a large wreck needs a few dives to truly do it justice.  Given its ideal location just a 2 minute boat ride from the dive centre dock it is an excellent first dive of the day.  The sheltered site is also diveable in all but the absolute worst weather so although deep, the water is usually clear with little to no current making it a very pleasant dive.  The site is superb for technical diving and a great training site for the Tec 40 and 45 programs, offered by Skopelos Dive Center.  

The Christoforos wreck was originally a collier ship built in 1950 at Grangemouth shipyard under the name “Thomas Hardie”.  In 1976 she joined the Greek merchant fleet as “Christoforos”.  On the 2nd of October 1983 the Christoforos was carrying 2600 tonnes of cement from Volos to Piraeus Port. During the voyage the weather turned, resulting in the ship developing a 7 degree list, whereby she changed course for safe anchorage at Panormos, Skopelos.  The ship reached Panormos at 16:00 with a list of 17 degrees and water ingress to No. 1 hull.  Though attempts were made to right the vessel, the crew were ordered to abandon ship at 22:00.  The captain, lieutenant and the quartermaster remained to try and save the ship, but had to abandon the attempt themselves and the Christoforos finally sank at 05:30 on 3rd October 1983.  She now sits upright in 43 meters of water less than 200m from shore in Panormos.

Diving has only been allowed here since 2018, so the wreck is very well preserved and a real treat to dive.  Permission to dive here was granted by the authorities after lots of incredibly hard work by the Skopelos Dive Center staff.  Having a fantastic wreck in such an amazing location and in excellent condition is a real privilege.

Of all the sites in Skopelos this was the site Mike and I were most keen to experience.  Having kitted up and zipped across the bay to the mooring, we left the surface and followed the descent line until the wreck emerged spectacularly from the blue at 15m.  She is a big and beautiful wreck, sitting as though calmly continuing her journey along the seabed.  With most of her original features still intact there were points of interest everywhere, including the anchors, winches, ships telegraphs, the wheel and RDF antenna.  

We found that aquatic life had colonised the ship, with schools of fish, electric blue nudibranchs, a large moray eel and the resident scorpionfish lurking inside the bridge.  The Christoforos was truly a stunning wreck and despite maximising our time at depth we eventually had to say our goodbyes and begin the slow and steady return to the surface. 

After a superb morning dive we had the afternoon to do a little sightseeing of the island, with a trip to the church of Agios Ioannis Kastri made famous by the blockbuster movie “Mamma Mia!”. Mike and I spent a happy afternoon pootling around in our little hire car before meeting up with Lina from Skopelos Dive Center.  An underwater archeologist as well as a dive professional, Lina had offered to show us a rather special attraction, the Christoforos shipwreck Digital Spot public information and awareness centre.

A fantastic initiative made possible from the collaboration of the government and hard work of the staff at Skopelos Dive Center is the “Digital Spot” in Agnontas port.  This information center has a number of displays on the history of the Christoforos wreck, the process by which the wreck was allowed to be opened to the public for diving tourism, other sites of historical interest in the area, a video of the wreck and the best bit, a virtual reality dry dive experience!  The beauty of the VR system is that non diving members of the family can see what you have seen on the wreck, or you can see areas that you may not have explored during the dive due to time or depth limitations.  It was a truly immersive experience and a great addition to the dive itself.

After a wonderful day we celebrated our last evening on the island with an exquisite meal in Skopelos Town with fabulous views over the town and bay, washed down with the excellent local wine.  The lamb with lemon and potatoes was a meal which I could happily eat every day for the rest of my life! 

Skopelos is an island that truly has it all.  The diving is excellent, the landscape is beautiful with plenty of non diving activities, the locals friendly and the food and drink superb.  Given how accessible it is as a holiday destination it has avoided becoming overcrowded and even in peak season offers a fun yet relaxing atmosphere.  We highly recommend giving Skopelos a visit.  We will certainly be back again!
