Everything You Need to Know About Your Snorkel, Part 1: Selecting the Right Snorkel

Published

on

What is the best type of snorkel for you? That will depend on a variety of factors, but chief among them will be the answer to the question, “What will you be using your snorkel for?”

The best snorkel can depend on whether you are:

  • Snorkeling
  • Scuba diving
  • Freediving

Let’s take a look at how these needs may differ.

1. Snorkels for snorkelers

People who use snorkels primarily for snorkeling can have very different needs than scuba divers and freedivers. Specifically:

  • Snorkelers generally prefer ease of clearing. Unlike scuba divers and freedivers, most snorkelers are self-taught. Thus, they most likely will not have had the benefit of someone teaching
    them the most effective ways to clear a snorkel.
  • Self-draining mouthpieces help make it easier to clear. A self-draining mouthpiece can reduce the amount of water that gets into a snorkel by half or more. Most snorkelers find this helpful.
  • Most snorkelers also prefer devices that reduce or prevent water from entering at the top. These devices can make a snorkel either semi-dry or fully dry. A snorkeler who does not have to give a lot of thought to clearing a snorkel is generally a happy snorkeler.

Snorkelers will also want features such as a comfortable mouthpiece and a large bore; however, these are features every snorkel user will want.

2. Snorkels for scuba divers

The first snorkel most divers purchase may, in fact, not be the one that can best meet their needs..

  • Most divers start out with a snorkel similar to what snorklers use, but may abandon it if they discover that, where they dive, snorkels have little practical use. There are also some very real down sides to having a snorkel attached to your mask if it is not needed, such as distraction, drag, potential entanglement and the fact divers often confuse their snorkel for their BC inflator.
  • At some dive sites, though, snorkels are helpful — and you never know when you might want one if stranded at the surface. In other words, it’s better to have one and not need it, than to need one and not have it.
  • A small, folding or collapsible snorkel, stowed in a pocket, lets you have a snorkel with you at all times without incurring the problems inherent with always having one attached to your mask.. Collapsible snorkels may have the further benefit of costing less, meaning that the money saved can be applied toward items you use all the time, such as better-quality fins and a personal dive computer.

Most folding or collapsible models also make excellent freediving snorkels.

3. Snorkels for freedivers

Freedivers have some very specific needs when it comes to snorkels and will seldom settle for anything less.

  • Freedivers overwhelmingly choose simplicity and streamlining over bulk and drag. In freediving, efficiency is key. Therefore, anything that creates unnecessary drag won’t be of much use.
  • Freedivers prefer open-top snorkels and consider anything else unnecessary. They rely primarily on displacement snorkel clearing, making snorkel-tip gadgetry unnecessary.
  • No self-draining mouthpieces as they prevent displacement cleaning. These days, such snorkels are harder to find — but worth the search.

As mentioned earlier, collapsible snorkels generally make good freediving snorkels and have the added benefit of being more readily available than rigid snorkels with these features.

What to remember

When choosing a snorkel, keep these three things in mind:

  • Snorkelers generally want a large-bore snorkel with a self-draining mouthpiece and some sort of device that reduces or eliminates water entering when submerged.
  • Rather than go without a snorkel, scuba divers can keep a small, collapsable snorkel in their pocket.
  • Freedivers will want a simple, streamlined snorkel with no self-draining mouthpiece and an open top.

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…
