Choosing your Technical Instructor: Explorers & Educators

Published

on

By: Allison White

As in every aspect of technical diving, choosing the right instructor should involve careful consideration and sound reasoning. Can this person teach me what I need to know? Do I agree with or can I learn from this person’s diving philosophy? What is this person’s teaching experience? How often does this person do the type of diving that I am hoping to learn? These are all very important questions that may take some time and research to satisfactorily answer. Technical students are often tempted to skip this time and research by basing their decision on one unrelated factor: How well known is this instructor?

Notoriety in any given realm of technical diving often stems from accomplishments in exploration. This is especially true of cave diving. Many divers wanting to take a cave or cavern class look for an instructor who is known in the cave diving community as an explorer. This explorer may be someone who dives sumps, surveys and maps virgin caves, sets new records for depth or time, discovers new cave biota, or researches the geology or hydrology of caves. The student is choosing this person to be their instructor based on these accomplishments, or often simply on other divers opinions of this person’s diving skills. However, these are the qualities that divers should consider when choosing a dive buddy, not an instructor.

When choosing an instructor, especially a technical instructor, divers should consider a person’s instructional skills, as well as their diving skills. While it is important that the instructor is an accomplished diver in the type of diving that they are teaching, have a strong passion for diving, and dive regularly, the student needs someone who can effectively teach them to safely achieve a knowledge and passion for technical diving of their own. This may or may not be an explorer.

Let’s look at a hypothetical scenario

I am a technical diver looking for a cave instructor. I am considering the following three instructors. Instructor A is a famous biospeleologist who has been cave diving for 40 years and still travels internationally at least four times every year to conduct cave diving expeditions for research. Instructor B is not as well known in the cave diving community. Instructor B has been teaching cave diving for fifteen years and also teaches a wider variety of technical diving, including wreck and ice diving. In the past five years, this instructor has done 50 cave dives, 45 of which were for instruction. Instructor C is also not as well known and has only been teaching cave diving for five years. This instructor doesn’t teach as many other specialties as Instructor B, but has done over 300 cave dives in the five years which they’ve been teaching, only 100 of which were for instruction.

I could choose any of these instructors and get a certification card

However, more than a card, I want to really learn about cave diving. I want to be as safe and informed as possible. I also want an instructor who can make me excited about cave diving. Instructor A is obviously very passionate about cave diving and has more experience in it than the other two instructors combined. However, I can’t find any information about his activities as an instructor. Other divers have only told me about his accomplishments as an explorer, and his website is focused on his scientific findings, though it does mention that he is a cave diving instructor and accepting students. I finally find a previous student of his and they tell me that while they learned a lot about biospeleology from him, he left most of the diving instruction to his graduate student, who was a divemaster. Despite being a famous scientist with an obvious passion for cave diving, Instructor A does not appear to have any passion for dive instruction.

Instructor B appears to have a great passion for dive instruction. His website is exclusively an exhibition of the various courses for which he offers instruction and is plastered with pictures of him diving with previous students. However, when I ask around the cave diving community, I don’t find anyone who has been cave diving with him for fun. I do find several previous students of his, all of whom assure me that he was a very thorough instructor and very few of whom ever went cave diving again after certification. Instructor B has the opposite problem from Instructor A: while he is very passionate about dive instruction, he has no apparent passion for cave diving itself.

Instructor C appears to be passionate about both cave diving and instruction. Many of the other cave divers I’ve spoken with have been diving with her and have nothing but high praise for her. I’ve also talked with several of her previous students, all of whom are still active cave divers and didn’t hesitate to share the many things that they learned from her. Her website is a balance between the instruction that she offers as well as her personal cave diving experiences, and has plenty of pictures of both. In the same amount of time, she has been cave diving six times more frequently than Instructor B, and two-thirds of her dives have been just for fun. After speaking with her on the phone, I discover that this instructor also shares many of my personal diving philosophies and has even more insights to offer. Even though she is not a famous explorer, Instructor C is clearly the best option among the three instructors for me to gain the knowledge and passion that I need to proceed.

Technical diving is often much more involved and dangerous than sport diving

It is imperative that students gain the information, passion, and experience that they need to become the next generation of safe and active technical divers. To achieve this is the responsibility of both the student and instructor. In order to ensure that you get the most out of your passion for technical diving, you should always be willing to spend the time and effort required to find the right instructor to help you get to where you want to be.

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.

Deptherapy returns to its Roots – Part 4

Published

on

Join Richard Cullen from Deptherapy for part 4 of his Blog about the charity’s recent expedition to Roots Red Sea, El Quseir, Egypt.

We are all back to the house reef today; the weather is lovely, the sea calm, the tide will soon be slack, so a great day’s diving in store.

A few yards away from the beach dive centre, on the Roots’ beach is their day time restaurant. It is where we take lunch when diving, and there is a continual supply of tea, coffee and soft drinks, and some marvellous lunches.  There are also male and female toilets and a fully accessible toilet for those using wheelchairs.

A few thoughts around working with amputees and those who have paraplegia. Firstly amputees – the part of the limb remaining is known as the ‘stump’, and we have worked with a substantial number of bilateral leg amputees (both legs), single leg amputees and single arm amputees.  The level of amputation can be above or below the knee or elbow, or through the knee. In one case the amputation was transpelvic and in another through the shoulder.  Some like Chris Middleton have one leg amputated above the knee and one below the knee.  This is rare, but each type of amputation offers a different challenge.

Many people think the amputation is clean and the skin neatly tidied up after surgery. Although that occurs in a few cases, in most the stump is rather rugged.  Elasticity of the skin around the stump is often exceptionally poor and can easily be damaged.  Some of our beneficiaries, as they were injured as young men, suffered from heterotopic ossification – this is where the bone tries to grow after amputation and often penetrates the skin, resulting in further surgery being required to cut back the bone and of course the stump needs to be restitched.  Very often stumps are sealed with skin from elsewhere on the body.

Swars kitting up

Few divers have never experienced a graze or cut underwater but such an experience for those with amputations can have serious consequences.  Stumps are more likely to get cut or grazed as the skin is so tight. We all know that there are lots of infections in seawater and if infected the cut or graze can cause very serious problems for the amputee.  Tailored wetsuits are one preventative measure, as are daily stump checks, making sure there is no damage and if there is, applying medication and or protecting the stump.

Those with paraplegia provide an additional challenge, not being able to feel their lower limbs they can easily damage them, so cuts, abrasions, and even sunburn can go unnoticed.  Donning a full-length wetsuit can be a challenge as toes can easily be broken and hairs pulled out of legs.  On the Deptherapy Education Professionals’ Course we show how to fit a wetsuit properly.

In recent discussions between our dive medicine advisor Mark Downs and our VP Richard Castle, who is a consultant psychologist, we have been looking at areas for further medical research in terms of diving for those with disabilities.  One area of suggested study is thermoregulation. The theory is that those with amputations and those with paraplegia suffer more with the cold as their body is unable to regulate heat. Certainly, in Corey’s case, he feels the cold more quickly than those diving with him. Chris Middleton can feel the cold more quickly than others with amputations but that may well be that Chris is muscle and bone where, to put it nicely, others have a more substantial covering.

Some AMEDs and Dive Referees will not sign off amputees as being fit to dive. That is their professional opinion and although we can show that even triple amputees are more than capable divers, capable of progressing to Rescue Diver standard even, they still refuse to sign them off. Last year Oli and Mark invited us to speak at the UK Annual Hyperbaric Medicine Conference in London where Josh Boggi, the world’s first triple amputee Rescue Diver and a Deptherapy beneficiary spoke about how amputees can become safe and successful divers.

Corey, Swars and Michael

For Corey, he wears full leg coverings and diving boots in the water; as he cannot use his legs there is no purpose in wearing fins.

Another point around amputations is that most of the general population make an assumption that a leg amputation is the result of a traumatic incident.  That is incorrect; by far the majority of leg amputations in the UK are the result of diabetes. Those whose legs are amputated as a result as diabetes are more likely to have poor healing of the stumps.  This also presents an issue of comorbidity that may well result in an AMED or Dive Referee declining to sign them off as ‘fit to dive’.  If signed off you would need to be very aware of the health of a stump; I certainly would not take someone with an open wound diving and the fact that they will be on medication for the diabetes.  You also have to be aware that they may well be on other medication to manage pain etc.

You need to be very clear with those who have paraplegia and other conditions that they must let you know if they start to feel cold.

Managing air – diving just using your arms for propulsion can, for many, be very tiring and a considerable amount of effort is required.  This, plus other factors, may result in enhanced air consumption by the diver.  This may increase if a current is encountered, even one which most divers who have use of their legs and dive with fins would not cause the least concern.

Within Deptherapy we very much work on the ‘rule of thirds’ – a third of your air to get you down and to see what you want to see, a third to get you back to the surface and a third in reserve.  This in most circumstances will ensure no ‘low on air’ or ‘out of air’ situations.

Say if we have 210 bar in a cylinder that means 70 bar out, so turn on 140 bar, 70 bar to return and to the surface so we should have 70 bar reserve at the surface.

We also work our students through SAC rates and looking at the air consumption of others in their team.

Checking the team’s air frequently during a dive is stressed to all our Pro team.

Keiron became very engaged with this concept as the result of the online RAID study for his Master Rescue Diver.

On expeditions we normally dive in small teams, a DM/TDM with three programme members.  They work as a team and understand each other’s air consumption. Of course, they also dive as buddy pairs.

Today offered perfect conditions for diving, and Keiron, Moudi, and this time TDM Oatsie were kitted up and in the water within minutes.

Pause for thought… those with paraplegia will have different toileting arrangements to those who do not have the condition. This also applies to some who have suffered traumatic limb loss.  They may use catheters for urination, some may have Stoma bags etc.  This all has to be planned into your dive schedule to ensure the safety and comfort of your student.  For young people talking about these very personal arrangements may be very difficult.  Those with Stoma bags may be embarrassed by people seeing them.  This is another part of seeing beyond the injury or condition – it is the person inside that you are dealing with.

Corey on the Roots House Reef

So, Corey, Michael and myself were joined by Swars.  Swars, although he joined the DM programme at the same time as the other guys, because of work commitments was unable to join us in September 2019 at Roots where we ran a DM introductory programme alongside the crossover of our Pro Team to RAID.  Swars has become a really good mate; he is a great diver, with an engaging personality.

Michael and Oatsie were a known quantity to me as they had been on the September 2019 programme and both have travelled to my home dive centre Divecrew in Crowthorne, Berkshire, to work on courses, pre-COVID.  During COVID Michael and I, plus a few of the guys from Divecrew, have dived at Wraysbury together.

Just as Roots is our base in Egypt, Divecrew is our base in the UK, and through this relationship, Martin (who owns Divecrew with his wife Sue) is one of our trustees. Together they have established a centre where pretty much 100% of the Pros are Deptherapy Education trained.

I asked Swars straight away to brief a dive for Corey. I gave him the briefing slate, a few tips and then ten minutes later he came back with a perfect briefing… and I mean perfect.  So, a great briefing under his belt; now to watch him work with Corey in open water. He looked the Pro, he knew what he should be doing, he understood his role. We assigned Michael as Corey’s buddy and said he would lead the dive. I was there to assess the TDMs and supervise very closely Corey’s skill demonstrations.

Again, it comes as no surprise that many beneficiaries in Deptherapy can move straight into dive management, as several were NCOs, as was Swars, and they are used to briefing individuals and teams.

We had decided that we would mix up the dives required to complete Corey’s OW 20 RAID dives with some general diving as trim and swimming arm action are all important. We also needed to concentrate on spatial awareness.

We agreed a signal for horizontal trim and Swars reinforced the swim stroke that Corey needed to do to get propulsion.  Every time Corey moved out of horizontal trim Swars was there reminding him about trim and reminding him of his swim stroke.

The Roots’ House Reef is amazing – at a metre you encounter a shoal of black Damselfish, at 3 metres a shoal of Unicornfish, there are Butterflyfish and all manner of other fishes in great profusion.  The coral is in great condition. It really is a place of beauty and tranquillity.

Oatsie and Swars relaxing by the Roots pool after a long day

Although we had problems getting Corey underwater again, once we got him in skill demonstration mode his anxieties disappeared.  We then took him diving. Steve Rattle, the owner of Roots joined us and was taking photos that provide a great record of the week’s diving.  Steve commented on the quality of Swars and Michael’s supervision and control underwater of Corey and gave them feedback on how impressed he was.

Meanwhile on the RAID Master Rescue Course, Oatsie who was in the same Regiment, same Platoon and Section as Keiron in Afghanistan was more than willing to be a very uncooperative victim for his brother-in-arms.  I think Keiron gave Oatsie some feedback about this!

For me this was a hard week, combining running the RAID OW 20 for Corey but also the assessment of our three TDMs.  A week underwater but no opportunity to dive for myself.  People often think Deptherapy Expeditions are holidays for the Dive Team; they are not, it is hard work and I mean hard work.

Tomorrow is Day 4 in the water Day 5 of our trip. We are on the House Reef again, and things are starting to come together. Join us back here on Monday 26th October…
