10 Top Tips To Conserve Air When Scuba Diving

As a scuba diving instructor working in Gran Canaria, the most common question people ask me is, ‘How can I make my air last longer?’ But why is conserving air when scuba diving so important for divers?

Put simply, more air means:

  • Longer dives
  • Increased bottom time
  • Greater chance of seeing more marine life
  • Becoming a more confident scuba diver.

Here are the ten ways to conserve air when scuba diving.

1. Breathe slowly and deeply.

The top tip to conserve air when scuba diving is learning to breathe properly underwater. Getting into a rhythm and taking longer, deeper breaths will allow your body to absorb more oxygen. By exhaling fully this will reduce the ‘’dead air’’ volume and will eliminate Carbon Dioxide. Reduced Carbon Dioxide levels will delay the urge to take another breath. You should never purposely hold your breath or expand your lungs beyond their capacity. Instead, you should pause for one second after taking a breath. This will allow fresh oxygen into the lungs and create a nice breathing pattern. In order to conserve air when scuba diving you may want to practice breathing slowly and deeply on the surface.

2. Swim slowly

As the fable goes, slow and steady wins the race! Scuba diving is a recreational sport, not a race. Doubling your speed will require about four times as much energy, more energy equals more air consumption. In order to conserve air when scuba diving you should relax and swim at your own pace.

3. Buoyancy control

Controlling your buoyancy is very important when trying to conserve air when scuba diving. If you are constantly having to add air to your BCD you will have less air to breathe! If you are using a lot of energy trying to descend or fighting to stay off the bottom you will become overexerted and breathe more.

 

Being neutrally buoyant when scuba diving will:

  • Save energy
  • Decrease the number of times you inflate and deflate your BCD
  • Reduce the risks of accidents
  • Conserve your air consumption

4. Being streamlined

Make sure your equipment is nice and trim. This will decrease resistance when swimming. Make sure your gauges and other diving gear are appropriately tucked away to create less drag. You should also swim in a horizontal position.

Other ways to reduce resistance include:

  • Keeping your hands by your side.
  • Look into buying shorter hoses to keep your hoses close to your body.
  • Make sure any accessories are tucked away. Snorkels, Knives, SMB’s will all create drag if dangling by your side.
  • Look into buying a BCD with more pockets in order to carry all the necessary equipment.
  • Make sure the equipment you are carrying is necessary. Avoid bringing items you will not need.

5. Reduce leaks

In order to conserve air when scuba diving, check your equipment. You should check all the connection points for any air escaping. Check your O-rings, SPG, inflator hoses and regulators for any mild free flowing. Before entering the water, turn your tank on and check that the equipment is in good condition if it isn’t, It is important that your equipment is checked by a qualified professional. You cannot put a price on your safety.

6. Fins cressi reaction fins

Yes, that is correct. The right pair of fins can help conserve air when scuba diving. Fins propel us underwater, they are responsible for our movement. If you invest in a pair of more efficient fins you will use less energy when diving. Less energy will conserve your air consumption. Feel free to get in contact with our team for any recommendations on the type of fins you should buy. Check out Divezones' blog on how to choose the right fins here.

7. Make use of your snorkel

Snorkels are a fantastic way to swim on the surface without reducing your airtime. Whether you are swimming on the surface, waiting for other divers or in wavy conditions, a snorkel will allow you to breathe whilst still conserving the air in your tank. I can advise using a fold away snorkel. This will allow you to put your snorkel in your pocket reducing the resistance on the dive.

8. Stay Warm

You should wear the correct exposure suit to conserve air when scuba diving. Heat is energy. This energy needs to be replaced by metabolism which uses oxygen to produce it. Diving in cold conditions can also cause stress and fatigue all of which will eat into your air supply! Whilst diving in Gran Canaria, we use 7mm exposure suits. You should conduct research on the water temperature of your diving destination before arrival. This will make sure you are prepared and preparation is key to conserving your air.

9. Exercise

A diver who is physically fit will be able to cope with strenuous conditions such as swimming into a current. They will be physically able to deal with the situation and it will not affect their rate of breathing. If you are unfit when the workload increases you will begin to breathe heavier and faster.

Ways to maintain a healthier lifestyle which will conserve your air include:

  • Avoid exposure to cigarette smoke
  • Avoid alcohol and high-fat content food
  • Participate in light to moderate exercise three times a week
  • Have a healthy and balanced diet

10. Practice makes perfect

The best way to conserve air when scuba diving is to relax. This will come with practice. The more you dive the more comfortable you will become and the better your buoyancy will be. Even professional divers never stop learning. You could look into advancing your skills with an additional course such as the peak performance buoyancy course. It is important to remember that a higher rate of air consumption doesn’t mean you are a less skilled diver. Here are some additional factors that could be contributing to your airtime:

  • Genetics
  • Size
  • Gender
  • Age

If you would like to conserve air when scuba diving follow these ten top tips and then just chill. Stressing about air consumption will only make you breathe faster!
