Safety rules for snorkelling with fins 

Snorkelling is an exciting and natural sport that anyone can do, on their own or with the family. But it is necessary to learn a few basic safety rules before taking to the water...

Snorkelling safety rules with fins

The basic attitudes to be adopted when snorkelling

At sea, it is essential to always show common sense. Consequently, we recommend a few safety rules:~- Never set off alone.~- Pay close attention to the weather.~- Make plans for one point of entry and several exits.~- Know your physical limits

Before setting off, inform someone you can rely on of your planned route, and remember to let them know once you have finished your dive...

Decathlon’s tips on safe snorkelling 

Doing a sport in a natural environment is often a magnificent experience, but one that involves the occurrence of a number of factors that could ruin your pleasure...~Let’s look at these factors in greater detail.

Wear some thermal protection to keep out the cold when snorkelling!

Keeping out the cold

Your body cools down more quickly in water than on land. Therefore, make sure that you do not stay in the water for too long, and to have a warm neoprene top or wetsuit. These garments must be the right size and adapted to the temperature of the water.~Shivering? Blue lips? These are signs that it’s time to get out of the water, especially for children, who are often less sensitive to the cold!

Preventing hydrocution

Always enter the water gradually, especially after spending a lot time in the sun. Wetting the back of your neck and the rest of your body with your hands is probably still the best solution.

Avoiding cramp and hypoglycaemia

Muscular cramp can be caused by a number of factors: low temperatures, a lack of sleep, alcohol, severe effort, poor physical shape, stress, dehydration, hunger or unsuitable equipment. To avoid cramp, swim gently using fins of the right size and adopt the right stroke. Buoyancy aids will also be helpful for children. It is also important to warm up before setting off, and to do some stretching exercises after the session. When snorkelling, it is generally a good idea to stay close to the shore to avoid any other problems.~~Like all other sports, snorkelling demands sufficient energy resources, depending on the level of effort. Hypoglycaemia is often characterised by moments of fatigue or cramp.

Possible hazards with your snorkelling equipment

Not much equipment is required to go snorkelling. Nevertheless, certain dangers may occur if the equipment is not used properly. Therefore, it is very important to read the equipment instructions and handbooks before using the equipment for the first time.

 

A snorkelling mask

Snorkelling masks 

We strongly advise you not to dive in head first with a diving mask! Even if the glass is very strong, there is always a risk of injury if it breaks into several pieces.

Free-divers should let a little air into the mask when descending. This prevents the mask from pressing against your face and giving you a black eye... When adjusting the mask, do not over-tighten it to prevent water from entering, as this can in fact have the opposite effect.

The easybreath mask

If you choose the Easybreath full-face snorkelling mask, you should follow a few rules... ~~The Easybreath mask, an innovation from Subea, Decathlon’s diving brand, must fit perfectly on your face to avoid any discomfort when diving at sea. So it is very important to choose the right size to prevent any water from getting inside the mask. As shown in the diagram below. ~But be careful! The Easybreath mask is designed for swimming, not for diving underwater. The mask restricts access to your nose, preventing you from using the so-called Valsalva technique.~~What is the Valsalva technique? It is a common technique that we have all used when in an aeroplane or in the mountains. It is used to make the transition between the pressure in the water and in the inner ear when diving. Divers and free-divers use this technique to send air into the middle ear through the eustachian tube to balance the ears. It is imperative to use this technique when descending, but never when returning to the surface! Hold your nose with your fingers and try to blow out through the nose frequently, but without feeling any pain. If you insist too much, there is a risk of barotrauma of the ears, which results in vomiting, dizziness, pain, blood loss and whistling.

The snorkel

When diving underwater, your snorkel fills up with water. Expel the water from the snorkel by gently blowing into it, once on the surface.

Breathe calmly and deeply to avoid any feeling of suffocation. Your snorkel must be positioned perpendicularly to your face prevent water from entering it when swimming in small waves.

Limit risks through regular care 

After each sea dive, you need to take care of your equipment (mask, fins, snorkel) to protect your safety and feel more confident the next time you go snorkelling with fins. This is quite simple. First, rinse your equipment, then soak it for a few minutes to remove the salt. Then, dry your equipment in the shade. If your snorkel has a valve, always check it for dust or grains of sand that could make the valve leak.
