Free Diving Beginner’s Guide

free diving

One of the things we will learn is the great diversity of interesting and competitive activities that come under the broad heading of free diving. For example, have you ever heard of “competitive apnea”? Probably not. But in free diving, holding your breath (“apnea”) is usually a good thing.

What Is Free Diving?

Free diving is a form of underwater swimming or diving where the person holds their breath through the duration of a single dive. Generally, the idea is to prolong holding the breath to enable the diver to go many meters below the surface of the water to experience and explore undersea life-forms and marine bottom-scapes.

In addition, these diving techniques can be used to enable many different forms of underwater activity, from spear-fishing to competitive diving, and even competitive apnea. All these activities share the need for the participant to hold their breath, usually for as long as safely possible.

Some of the benefits of free diving compared to scuba diving, which requires the use of an underwater breathing apparatus (diving tanks, etc.) are:

  • Much lower equipment cost—free diving does not require any equipment at all
  • Free divers don’t have as many safety concerns as scuba divers
  • Free divers are “free” of heavy equipment—so can move about more naturally
  • No excess bubbles—the sea life doesn’t get so startled

We should clarify a couple of points here.

While it is true you do not need any equipment at all to begin free diving, many free divers do use equipment, which we will discuss in more detail below. But basically, mask, fins and sometimes snorkels can be used by all divers, including beginners.

While it is true free divers do not face as many risks (few decompression concerns for example) as scuba divers, this does not mean that free diving is risk-free. Obviously, that is not likely to be the case with an activity where the main idea is to hold your breath. Learning how to properly breathebefore and during a dive is an important safety concern. Again, we will look at this in more detail below.

Free Diving Is Ancient

It should not surprise us that an activity as natural, and essentially low-tech, as free diving has been around for thousands of years. And this is especially the case since global coastlines offer such an abundance of food, much of it accessible to free divers.

Not only have free divers explored for food, but their special skills, which can be honed to enable very deep and very prolonged dives, have been employed by those with other goals entirely. For example, we know that in 332 BC, Alexander the Great employed breath-holding divers (free divers) to help dismantle the defenses of Tyre, an ancient Phoenician coastal stronghold.

And free-diving techniques, especially long breath-holding abilities, have been key in the development of survival skill-sets for US Navy personnel, especially submariners.

However, for most people drawn to this kind of diving, their goals are much more personal—learning how to free dive better and more safely in order to have a great time!

Is Free Diving Safe?

It may seem a little strange to consider this as a safe activity when you intentionally hold your breath for as long as possible and then plunge as deeply as possible underwater.

But, the breath-holding is usually a means to an end—the enjoyment of the considerable rewards of exploring a part of our world that most people will never see up close and personal. That amazing experience can most certainly be achieved safely.

Sure, there are risks involved in any kind of diving. And, the key to managing those risks is to know what they are and to take them into account in your preparation and performance of each and every dive you do. So, let’s take a look at what that means with this most natural kind of diving.

Remember, unlike in scuba diving, and even in snorkeling, which enables you to breathe just under the surface of the water, free diving is based on the idea you will be holding your breath through the dive. For beginners, this is something that may seem a little scary at first. How long is safe? How deep should you go?

Before we answer particulars about safe beginning dives, we need to talk about the most important thing—breathing, and not breathing. And the main thing we need to look at is how your body breathes, and how and when it makes you breathe—especially when you are trying not to.

How We Breathe and Don’t Breathe

Each breath we take is in two parts:

1. Inhalation—the lungs draw air in and retrieve oxygen
2. Exhalation—the lungs expel air and eliminate carbon dioxide (CO2)

Oxygen Is required to perform energy production in our cells, including in the cells of our brain. Without oxygen, our cells are quickly starved of a key fuel component, and if the oxygen deprivation is in the brain, we lose consciousness and soon die.

Carbon dioxide, on the other hand, is a byproduct or a waste gas of our cells’ energy production process. This gas must be removed by the lungs through exhalation because too much carbon dioxide is toxic to us.

So, as you may notice here, the whole breathing process is based on a balance between these two gases—oxygen and carbon dioxide. Our body has sensors inside it that monitor the amount of both of these chemicals in our bloodstream.

Interestingly, the main sensor, the one that basically makes us breathe, is the one for carbon dioxide. When CO2 levels get too high, the urge to breathe will eventually force us to take a breath, even if we are trying not to.

This helps to explain why many free divers practice loading up on oxygen and eliminating carbon dioxide, for example by hyperventilating, before a dive. And, that can be a big safety problem.

What Are the Essentials of Safe Free Diving?

Essential Gear You Need

The good news is that there is no essential gear to begin having fun with free diving. As we have noted above, the only tools you require to do this ancient activity are your body and the ability to hold your breath while underwater.

However, as you develop your skills, and as your objectives and goals motivate you to go deeper with your dives, you will likely want to investigate the gear that can dramatically improve your diving experience and performance.

And, the truth is, that even beginning divers can benefit from this gear, so “essential” is determined greatly by the diver.

Tools of the Dive

So, let’s say you want to start off your diving experience with the right gear. What is that?

There are basic elements of diving/swimming gear that pretty much all divers will want to have.

These include:

  • Mask—should be watertight, fit your face, and give a clear field of vision
  • Fins—these fit on your feet and magnify the power of your leg-strokes
  • Snorkel—not essential but this tool gives you more options

The mask covers your face and nose, giving you as clear a view of what is around you as you can get. You will want the mask to fit tightly enough to prevent leakage, but not so tight that it leaves marks on your skin. You should try out masks at a dive shop because the fit is impossible to determine online.

As for fins, the idea is to magnify the power of your stroke or kick through the water. Generally, the longer and more responsive the fin, the more power you will get for each stroke. This will move you faster and deeper through the water while not burning as much of your precious oxygen. Plastic fins are cheaper, but generally, won’t have as much water-moving power as more expensive fiberglass and carbon-fiber fins.

Finally, snorkels do not have to be expensive or have special features to do the job. The idea of the snorkel is to give you the ability to breathe, through the tube sticking in the air, while your face is just immersed in the water, enabling you to have a shallow-water view of what is below you. If and when you decide to dive beneath the water’s surface, you are then using breath-holding techniques just like any free diver.

Your Free Diving Guide

Here, in addition to the information we have already provided you, is a basic guide to getting started with free diving.

How to Prepare for Your First Dive

Assuming this dive will be happening someplace more challenging than the deep end of the swimming pool, where the basic safety rules still apply, there are a few things you will want to make sure you have done before beginning your dive.

For one thing, the more fit you are, the easier it will be to perform the physical functions of the dive. If you are seriously out of shape, you may want to improve your physical fitness a bit before beginning diving.

Some other basics to learn:

  • Learn how to breathe
  • Learn how to equalize
  • Learn how to dive

Breathe Right—Then Dive

So, what does it mean to learn how to breathe?

Remember, we talked about the dangers of the wrong kind of breathing and how that can lead to shallow water blackout. But, at the same time, you want to prepare your body so you can safely maintain your breath for as long as possible underwater. The basic guideline to follow is to saturate your blood with oxygen, but do not try to drastically reduce your carbon dioxide level; so, no hyperventilating.

Instead, take long, relaxed breaths combined with even longer exhales—that will prevent you from exhausting the carbon dioxide in your body. When you are ready to dive, completely empty your lungs and then take one, deep breath, completely filling your lungs.

Then take your dive. After the dive, remember to spend time on the surface recovering. Your breathing should return to normal before you try to dive again.

What Is Equalizing?

As we descend below the surface of the water, the pressure of the air inside the mask and in our sinuses increases. This will cause pain and potential injury if the pressure is not equalized.

To accomplish this, you must force air into the mask and into your sinuses. There are a number of methods to equalize air pressure in your sinuses, but you will need to release a small bit of air from your lungs to equalize the pressure in the mask. Since you are starting out with a limited air supply, you want to practice this technique to release only the minimum amount of air required to equalize the mask.

How to Dive

Again, this may seem strange to you. Doesn’t everybody know how to dive into the water? But, there are way more efficient ways to do it that you can learn and practice. For example, you can learn something called a “duck dive”, which mimics a duck’s highly efficient dive motion. You can learn to use diving fins to magnify the power of your stroke so you get to the depth you desire with as little energy and oxygen expenditure as possible.

Conclusion

In this article, we have covered some of the basics of learning what free diving is and what you will need to learn to do it. Always remember that in free diving, there are right, safe, ways to do things, and you should learn those ways and practice them. You’ll have a lot more fun that way.
