If you are fascinated by the underwater realm, by dolphins, whales, fishes and coral reefs, perhaps the inhabitants of your local waters, or simply nothing less than the uncharted depths and secrets of the ocean … well, then scuba diving will suit you perfectly! Diving is a nature sport which can be learned at almost any age and gives you the opportunity to roam completely freely in your environment. Diving allows you to enjoy almost complete detachment and gain new perspectives from the world below – something otherwise only experienced by pilots and astronauts. And the step to make this dream a reality is not as difficult as you may think.
Many years ago, when I looked for the first time into the educational aspect of diving, I was sobered by all the technical and theoretical knowledge, as well as the physical aspect of the training and my own (pretty poor) condition. It seemed unattainable, something clearly made only for silver screen heroes.
I jumped into the adventure with sometimes shaking knees but I soon realized that it was not actually that complicated if you threw in a little bit of common sense. My excitement for the underwater world grew with every fluke swing and as a passionate painter, I captured many of my impressions in paintings and drawings.
Like they say “Why make it difficult if it is simple?“. This book is my small contribution to bring you closer to diving and to ease the way a little. Together with the diving amateurs, Tim and Jenny, we‘ll go through the basics step by step, illustrated and with easy-to- understand texts.
We’ll take a look at what awaits you, independent of any diving organization. Think of it and use it as a companion book for your training.
In every case, you should start your training with a worldwide acknowledged organization which provides you with a good and solid education, including highly qualified diving instructors. You‘ll find an introduction to the top-ranking organizations in the appendix to this book.
I hope you succeed!
With all that said, I must give many thanks to the always caring and cautious diving instructors of my diving club ‚SGS Ostfildern‘, of which I have been a fond member for over 25 years and where I was trained myself. Thanks to my family, for the support in the making of this book with patience and motivation and to Werner Scheyer, a long-time friend of the family and a famous diving technician and instructor, who carefully looked over the text. I also want to thank Dr. Uwe Hoffmann of the Cologne Sports Academy for the scientific verification of techniques and practices and Sabine Kaiser, instructor at i.a.c. for her suggestions.
-Where do you have to go?
-What do you need?
… one may dream of the richly colored animal kingdom or the sightings of big and small fish. Another may want to explore wrecks and find historical treasures. No matter what reasons drive you to jump into the underwater realm, today it is easier than ever.
Let‘s start …
The best place to go to is a diving base or school close to you or you can join a diving club with youth membership. Diving schools and clubs usually offer additional possibilities to go diving off-season, and you can find people with similar interests for diving in your region. You‘ll find the main addresses in the appendix.
During vacation, you can visit the training courses given by a local diving school to receive diving instruction. They will teach you the important theoretical and practical basics and will deal with common needs and wishes.
It is very important that you‘re healthy. This means you will need a quick medical checkup. Also, you shouldn‘t dive with a cold, a temperature, or allergies, or generally if you feel sick or unwell because diving has a lot to do with your breathing organs. But more about that later.
If you have any doubts whether you are allowed to dive, ask a doctor without hesitation. Generally, parents must give their permission before adolescents are permitted to start scuba training.
Your diving instructor will first introduce you to what is known as the ABC equipment. ABC has nothing to do with preschool in this case, but stands for the first three main parts – or the basics - of diving gear: mask, snorkel and fins.
It is vital for the mask to fit well and to provide a second seal topping. Nothing is more uncomfortable than not being able to see clearly underwater, because your mask is leaking or letting water in. The best way to test whether the mask shape fits you is to put the mask on without the strap. Put a little bit of pressure on it and breathe in through your nose, holding your breath for some seconds. If you let go now, the mask should stay in place due to the suction pressure. If it does not, the mask is too big. If it leaves clear pressure marks, the mask is too small. In addition, the mask should provide enough space for the nose to be easily held by two fingers. This is important to equalize pressure.
There are masks in all shapes and sizes. Some prefer separate glasses and ‚professional black‘, others want as much view and as many shiny colors as possible. They also come with optical glasses. If the mask fits well, contact lenses can be worn without a problem.
One tip for a clear view - it’s not to everybody‘s taste but it helps - guaranteed: Before placing the mask, spit in the dry mask and cover the whole glass from the inside. Then clean it quickly with water. This prevents the mask from fogging because the spit contains encymic probes to remove the layer of fat on the glass. There are also special cleaning liquids that provide the same effect, but they are not always at hand.
Fins come in various colors and shapes. Normally, one can differentiate between full foot-pocket fins and open-heel foot-pocket fins. The first have a continuous foot bed because they are worn barefoot and are mostly used for snorkeling or training.
