Five Ways to Conserve Air While Scuba Diving

Guest Post written by Austin Jacob

Air preservation is a topic that’s completely ignored by scuba diving beginners as there are so many other things for them to focus on. After learning the basics, it’s extremely important for divers to learn proper air preservation technique so they’re able to get the most out of their dives.

Tip #1 – Get Proper Fins

Having fins that are comfortable yet efficient is vital to saving energy when diving. By using the correct fins, you’ll get the most force out of your thrusts allowing you to dive for a longer period of time. I’d recommend trying out a few different fins and then make a purchase when you find ones that work well for you. Read this guide to learn more about some of the top scuba diving fins out there.

Three Simple Steps to Avoid Panic Underwater

You started your scuba diving course and you are on the shore /  poolside.

Your scuba diving instructor wanted you to kneel and breath underwater after a briefing about your very first scuba diving session. 

Maybe you were an amateur free diver and got used to with the mask, snorkel and fins, but not a tank and a regulator!

You are just like a koi out of its pond.

At this point, you may feel like in two different ways:

  1. Excited about what you are doing! You think breathing underwater and watching the aquatic environment is fantastic!
  2. Stressed about what you are doing! You feel extremely uncomfortable and want to step on the land again asap!

If you belong to # 1, go ahead and enjoy your dives. 

Whereas if you are # 2 type, I have something for you.  [Read more…]

Key for Success in Scuba Diving

I am a scuba instructor for more than 15 years in PADI, SSI, NASDS and CMAS

I have trained over 750 scuba diving students in this period. 

When I start an Open Water Diver Course, I know two things will possibly happen throughout the course;

  1. My student, regardless of age, sex and nationality, will be afraid to try to conduct the “removing and replacing the scuba mask skill” 
  2. He / she will most likely think that scuba diving is a hard sport / activity requiring endurance and “maybe it is not something for him / her” (fewer than #1 but still valid)

In this post, I want to show you the way for success in scuba diving and how to kill these two points above (if you also have / had them) easily!

Ok, let me start with the first one;

Removing Mask: A Challenging Dive Skill

Majority of student divers and inexperienced certified scuba divers find this basic skill difficult. They have the fear to perform mask removal.

The reason behind this fear is that we are evolved/created (choose the one you like) to live on land, not underwater.

We eat, drink, dance, walk and see on land. We do these for years and know nowhere else to do such kind of activities!

However one day, a bald scuba instructor like me takes you into the ocean and wants you to breathe underwater! Isn’t this “a little bit weird already, even though it is fascinating” you are thinking…

Like this ain’t enough, your instructor wants you to perform some diving skills! He/she is demonstrating these skills easily. But when your instructor gives you the “now your turn” signal, those skills start not to be that easy, huh?


You are a certified scuba diver but you completed your diving course a couple of weeks ago.

You were removing your mask, feeling a little bit anxious, but handled it. But you still have a piece of fear against this skill.

What if I need to replace my mask if it is removed from my face in my open water dives one day?!

Do you match with one of these two profiles?


First, you are not alone!

Removing Your Mask UnderwaterAs I have mentioned above, majority of the student divers and unexperienced scuba divers find mask removal a really challenging scuba skill.

Because when you remove your mask underwater, water surrounds your eyes, mouth and nose. When performed in open water as a part of scuba diving training, salty water may disturb you. This is extremely normal.

In addition to this, we are used to inhale through our nose. This is a reflex for us and it is difficult to control.

However, we should inhale and exhale through our mouth underwater. That’s because we are using a regulator second stage for breathing there.

And when we inhale through our nose when we remove our mask underwater, water comes in! This disturbs us naturally. We need to cough and take deep breaths to overcome this issue, right? [Read more…]

5 Ways of Self-Improvement in Diving

You did it! From now on, you are a certified scuba diver. All the academic sessions and the training dives are over.
You are looking at your brand-new dive certification and becoming proud of you. Now you can dive as long as you want, share your experience with your friends and family. You became one of the guys in National Geographic Channel whom you were admiring just because they were diving in a harmony. How cool you feel now!

However, this is only a start, the beginning of your scuba diving journey. It is a life-time hobby that will turn into a life-style in time. Like all the other relationships you have, you and scuba diving will mature by time which will lead you to an amazing life experience.

In this article, I wanted to help you make safe and comfortable dives. Knowing and applying these simple “tips” will make you better divers.

Alright then, let’s start.

Maintaining and Developing Your Scuba Diving Knowledge

We forget. That’s the truth. To maintain what we learnt, we should repeat. The entry level course books are the base of our scuba diving knowledge. Whichever your diving agency is, your “starter book” should always be on your desk.

From time to time, take a look at the chapters. Not the whole book maybe, but the key points in it. I suggest you to highlight the parts that you tell as a key point. It is then easy to find these lines when you decide to re-read it.

This is only the maintaining part. It is the base of our “house of diving.

You should read monthly well-respected dive magazines, follow a TV show in an alternative channel like NetGeo, Discovery and/or Animal Planet, read other books (in addition to your own diving manual) written by your favorite doyenne scuba diver.

By this way, you’ll learn new things and be able to follow the trend in scuba diving.

A good knowledge will make you a better and conscious diver. [Read more…]

Controlled Descent Is the Best Start

Mustafa and I were in Antalya-Kemer/TURKEY for diving several years ago.

It was a wreck dive.

We were not alone. Our group consisted of 6 scuba divers (including us) and a dive leader.

I and Mustafa were instructors, but the rest were starters.

Right after the dive briefing, dive leader told us that me and my buddy Mustafa may stay at the back of the group while enjoying the dive and serve as a rearguard for him.

That was no problem. We accepted. [Read more…]

Choosing the Proper Amount of Weight

Diving requires balance.

Balance (called ‘buoyancy‘ in scuba diving) should not only be horizontal, but also vertical.

Vertical balance means ‘not to sink nor to float.

To be able to make safe and enjoyable dives, you need to be ‘neutrally buoyant.

I advise you to read Buoyancy Underwater: Tips for Perfect Buoyancy article to learn more about buoyancy underwater.

One of the elements of buoyancy is the amount of weight scuba divers use.

What is a Diving Weight?

Usually made of lead, diving weights help a scuba diver ‘to be able to get under the water.

All the equipment a diver uses makes him/her float (positively buoyant).

Even the dive tanks/cylinders acts like a buoy at the last minutes of the dive. Because the pressured air in the tank will decrease.

Wet-suits, buoyancy compensators and every other equipment… They will all try to pull you to the surface.

To balance this, scuba divers use weights. You can read Weight Systems page for more information about the weight systems in scuba diving.

Why to Choose Proper Amount of Weight

The ideal amount of weight a scuba diver uses should not make a diver ‘crawl on the ocean floor.This will make the diver to use more air.

That’s because diver will want to be neutrally buoyant and inflate his/her BCD with more air. In addition, diver will consume much more energy.

Think about yourself walking with an extra 10 kg, right?

Using more air means less bottom time.

On the other hand,the ideal amount of weight a scuba diver uses should not make a diver ‘float like a balloon on the surface.’

This will make the diver struggle to be able to descent and start to dive.

Even if the scuba diver can succeed to descent, he/she will possibly ‘dodge’ to the surface when air in the tank is decreased.

This will result in an unenjoyed dive. But beyond this, rapid ascend is not safe (read: Decompression: Sickness or Illness).

How to Choose Proper Amount of Weight

It is quiet simple.

First, consult your instructor for the amount of weight you should choose and put on that amount of weight to your weight belt.

Then wear your wet-suit/dry suit and put on all the diving gear you use. Fins, mask, scuba and everything…

  1. Get in to the water that your fins tips don’t touch the bottom.
  2. Wear your mask and regulator.
  3. Inhale slowly while deflating your BC
  4. Hold your breath for a couple of seconds
  • If you start to descent, you have more amount of weight than you need.
  • If the water level is on your eye-level, you have ideal amount of weight.
  • If the water level is on your -for example- shoulders, you have less amount of weight than you need.

Some Examples

Let’s take some examples for a better understanding.

Case 1

You put on 10 kilograms of weight.

Applied all the steps I have mentioned above.

With a fully deflated BC and normally holded breath, let’s assume that you start to descent.

You should retry this test with 8 kilograms of weight.

Case 2

You put on 6 kilograms of weight.

Applied all the steps I have mentioned above.

With a fully deflated BC and normally holded breath, let’s assume that the water-level is at your shoulder-level.

You should retry this test with 8 kilograms of weight.


Choosing the right amount of weight is very important, because it directly effects our buoyancy (balance).

With the test explained in this article, you are going to be able to choose the ideal amount of weight and make safe and enjoyable dives. 

Remember that every single change in your equipment and your own weight will effect the amount of weight you’ll choose.

Wearing a shorty means to put on less weight. If you are using 10 kilograms of weight in winter, you should use something like 8 kilograms (find the exact amount buy applying the test) while wearing a shorty in summer.

Using an aliminum tank requires you to use more weight because aliminum is a lighter metal than steel. If you are using 8 kilograms of weight with a steel tank, you should use something like 10 kilograms (find the exact amount buy applying the test) while using an aliminum tank.
