Scuba Diving Instruction: 12 Essential Rules Every Student Should Master

Not holding your breath is one of the fundamental diving instructions for practicing this sport safely, but there are more. In today’s article we are going to review the most important diving instructions like a mantra, so that you do not forget even the smallest safety detail, before, during and after a dive.

Looking for professional scuba diving instruction?

Learning the essential rules is the first step to becoming a confident diver.

Whether you are starting your scuba training or looking for a refresher, these 12 safety guidelines cover everything you need to know before, during, and after your dive.

1. Scuba Diving Instructions to Prepare Your Dive

1. Get your scuba diving certification. This is one of the diving instructions that we will not tire of repeating.

Having, at least, your Open Water Diver certification will allow you enough autonomy to make interesting dives without going hand in hand with an instructor or a Dive Master.

If you haven’t been diving in a while, take a refresher course. Choose a reputable certification center that has operated in this location for a long time.

How to Get Started with Scuba Diving Instruction

Before mastering the rules, you need to choose your path. Most professional scuba diving instruction follows these steps:

• Discovery Scuba Diving (DSD): A one-day “try dive” for beginners.
• Open Water Certification: The full course to become a licensed diver.
• Advanced & Specialties: Deep diving, Navigation, and Wreck diving instruction.

What to Expect from Professional Instruction

Open Water scuba diving instruction isn’t just about reading a manual.It is much more.

2. Dive within your limits. 

A key part of any diving instruction is recognizing your personal boundaries.

It is in the DNA of every diver to want to improve, dive longer, deeper… and that is perfect. Do it, but first, make sure you have the necessary specialization courses and skills first.

Certifications and specialization courses will be your allies, as you can see, training is one of the fundamental scuba instructions.

On the other hand, you should not dive if you are ill, for example. If you have a cold, fever, or feel dizzy.

Reminder: Diving is contraindicated if you are pregnant.

You should also not submerge if you are under the influence of alcohol, drugs, or tranquilizers.

Do not stay up late the night before a dive, better rest, hydrate, and eat properly.

3. Plan your dive, dive your plan.

In addition to being a famous sentence, it is one of the scuba diving instructions that will prepare you for what awaits you underwater and, therefore, to practice this sport with the greatest safety.

Effective scuba instruction emphasizes the importance of the pre-dive briefing.

Pay attention to the briefing if you dive with a guide, if not, plan the time of the dive, the maximum depth to which you are going to descend, and make sure you know how to navigate the site to find your way back.

If this is your first-time diving with your dive buddy, agree on the signals with him or her, they often differ depending on where and with which agency he or she learned. Once you’re in the water, follow your plan by checking your gauges, so you don’t exceed your bottom time.

4. Check your equipment.

Scuba gear is what allows you to be underwater, so check your gear and your partner’s gear before entry.

2. Scuba Diving Instructions During Your Dive

1. Never hold your breath

We said it at the beginning of the article. This is the golden rule of scuba diving instruction.

Every lover of this sport knows that pressure differences affect the air we keep in our lungs, so as long as you breathe normally, we will avoid over-expansion with pressure change. So, remember: keep breathing.

On the other hand, slow, deep and continuous breathing will help us reduce air consumption and to have precise buoyancy control.

2. Follow the buddy system

Safety standards in scuba instruction rely heavily on teamwork.

Diving following the buddy system is the best way to dive safely because diving emergency actions depend largely on it.

Besides, he/she is your alternate air source if the situation calls for it. Therefore, keep your dive buddy in your field of vision and at a maximum distance of 5 meters, if water visibility permits it.

If you lose him or her, you should search for each other for 30 seconds, and if you don’t find one another, ascend. We recommend reading the article: How to Find A Dive Buddy? – Everything You Need to Know.

3. Consume as little energy you can 

Reduce movement, dive warmly enough and relax.

Stress, strenuous physical movement and being cold will cause you to consume more energy and thus demand more air from the tank.

4. Make safe ascents

The recommended ascent rate is 35 feet / 10 meters per minute.

So, if you dive within recreational diving parameters, you can get rid of the additional nitrogen your body has absorbed and you won’t need to make decompression stops.

Your computer will warn you if you ascend at an incorrect speed. If you don’t have one, watch your bubbles and ascend at the same speed or less than the smaller bubbles. Make the safety stop as you were taught in your Open Water course.

5. Respect the natural environment

Although this is one of the diving instructions that may not seem to have a direct bearing on safety, in reality it does.

Complying with this rule will avoid dangers both for the environment and for the diver himself, who could be injured or suffer allergies and irritations.

Eco-friendly practices are a vital part of modern scuba diving instruction.

3. Scuba Diving Instructions After Your Dive

• Avoid making demanding physical efforts. After a dive. Your body has been subjected to different pressures; it has absorbed nitrogen. Therefore, activities such as running, lifting weights, or hard training may alter the internal gas balance.

• Record your dive in your logbook. Want to know why this dive instruction is so important? We tell you in this article. The Diving Logbook, Why Is It So Important?

• Wait at least 24 hours to fly. This is another of the diving instructions that we have already considered previously in this blog Flying After Diving and Diving After FlyingDon’t miss it, in it we tell you the reasons why waiting is better.
