10 rules of scuba diving every diver should know

Scuba diving is a fun activity, however, we always need to follow the rules of safe diving.

Here are the 10 rules of scuba diving every diver should know and adhere to. If you do, you will be safe throughout all your dives and reduce the risk of accidents and emergencies.

1 Always keep breathing

This is arguably the most important rule in scuba diving and the first one most people learn. It’s also one thing your instructor will repeat over and over and over…and over..and over…again throughout your beginner course.

In our Discover Scuba Diving courses, we like to say: “If you remember just one thing about scuba diving, then let it be: Diving is fun, and never hold your breath!“

By breathing continuously, you prevent overexpansion of your lungs during ascending which could lead to barotrauma, injuries, and worse.

Normal, rhythmic breathing also improves your buoyancy and reduces air consumption.

2 Never dive alone

In recreational scuba diving, we always dive in a buddy team. Always. No exceptions.

The buddy system greatly reduces the risk of accidents and fatalities in scuba diving and it is also more fun than diving alone.

I simply let the numbers speak for themselves:

Yes, certain agencies and dive schools offer courses on “solo diving”, however, I strongly advise against diving solo ever!

Certain countries like the Maldives even ban solo or solitary diving by law altogether.

3 Stay within the limits of your training

It is important to stick to the limits of your certification level, as well as the generally accepted limits of recreational scuba diving.

Here is a little refresher on the depth limits imposed by most training agencies:

Note: These limits apply to recreational diving only, and differ in technical and freediving)

4 Take pictures, leave only bubbles, keep the memories

This is as much a rule, as it is good diving etiquette. We do not touch or take anything from underwater unless it obviously doesn’t belong there.

This refers to both animals and items, rocks, or other non-living things.

The only exception here is plastic and other harmful trash that you should definitely take with you and throw away after the dive.

5 Dive only when you’re healthy

This should be common sense but is especially important when scuba diving:

Only dive when you feel healthy to do so and never when you have a cold.

Being sick not only makes diving in (cold) water very unpleasant, it can also block your sinuses which prevents you from equalizing properly underwater.

6 Don’t ascend too fast

Stick to the ascent rates taught in your Open Water Diver course to reduce the risk of getting Decompression Sickness (DCS).

If we ascend slowly, and the pressure around us gets lower, the Nitrogen can be released from our body in a controlled manner.

Take a 3-5 minute safety stop at 5 meters depth on every dive to make your ascent even safer.

In case you are confused as to why the pressure changes, here is a refresher on the most important scuba diving gas laws.

7 Plan the dive – dive the plan

The foundation of every fun and safe dive is thorough dive planning.

Plan ahead and when you’re underwater, stick to it. This way, you and your dive buddy know exactly where to go, how long to stay, and how to react if there is an emergency.

8 Check your gear

Check your dive equipment before every dive and make sure it is safe to use and set up correctly.

Do the same for your buddy during the buddy check and familiarize yourself with how it works.

9 Constantly monitor your instruments

Throughout your dive, you should always know your depth, dive time, and tank pressure. You would not want to be out of air on your safety stop, right?

Therefore, it is super important that you constantly monitor your gauges and instruments like SPG (submersible pressure gauge) and dive computer.

10 Always have fun

I know this one seems out of place after all the technical and safety rules from above.

But the truth is, having fun is the reason why we go diving in the first place. Plus, it increases your safety during a dive:

We see this all the time with first-time divers. If they are excited to go diving and really want it, they are always much better than those, who don’t really want to be underwater.

So enjoy your time underwater and appreciate every minute of it. 😃

Conclusion

That’s it. These are 10 rules of scuba diving every diver should know, in my opinion.

Of course, there are many more rules and regulations we need to follow as scuba divers. However, if you stick to these 10, you will be a safer diver and a better buddy.
