Tips To Help You Conserve Air

Today we are going to look at some tips that could help you control your air consumption. Making your air last as long as you possibly can is important in scuba diving.

Having more air means longer dive times, it can also mean the difference between life and death if a diver were to become entangled while underwater.

  1. Get In Shape – If a diver is overweight or out of shape, they are naturally going to consume more air than a diver that is fit and trim. The more streamlined you are the easier it will be for you to move through the water using less effort.
  2. Relax & Breath Slowly – Relaxing while diving is one of the most important aspects of air conservation. Take slow, seep, re;axing breaths. The natural tendency is to breath much faster than when on land due to stress and the anxiety of being under water. This translates into faster air consumption and shorter dive times. Breath normally, as on land in a slow relaxed pace.
  3. Don’t Use Your Hands – Waving your hands around to move and control your position causes your body to use a lot of oxygen. The muscles in your arms a much smaller than those in your legs and consequently if you use them to maintain position and move around with they need a lot more oxygen than the muscles in your legs do. Learn to swim with your arms at your side to stay as streamlined as possible and let those big leg muscles do the work for you.
  4. Slow Down – Scuba diving is not a race or a competitive sport. Learn to slow down and make your movements graceful and relaxed.
  5. Buoyancy Control – One of the biggest things that new diver can work on that will help them to conserve air is their buoyancy control. Staying neutrally buoyant throughout the entire dive not only protects the fragile underwater environment, but it saves energy and air. Being neutrally buoyant keeps divers from accidentally bumping into delicate coral which can take hundreds of years to grow and become established. If bumped and a piece breaks off, it can take up to ten tears for every inch of regrowth. When a diver is neutrally buoyant they are able to stop finning and remain motionless off of the bottom. If they are negatively buoyant they will sink to the bottom if they stop finning and if they are positively buoyant they will rise up. Getting buoyancy and ballast weighting correct will do wonders for a divers air consumption.
  6. Watch Your Weight – We already discussed your body weight, now we are talking about the extra weights that you will be putting into your BCD or weight belt. The heavier the diver is the more air they will have to add in their BCD’s to compensate to achieve neutral buoyancy. Think of your BCD like a big balloon strapped onto your back. As a balloon is inflated it gets bigger, and the bigger something is the harder it is to move through the water. This is because it is less hydrodynamic and streamlined and causes a lot of resistance when being moved through the water. The more streamlined an object is the less resistance it causes, and the easier it glides through the water. You need air in your BCD to compensate for your ballast weight to achieve neutral buoyancy, but by being weighted too heavy you will need more air. The heavier you are the more air you will need to compensate. I recommend taking a class like the Buoyancy Specialty offered by PADI. This class was one of the best classes that I have taken since I started diving. I learned so much in such a short amount of time about buoyancy control that I was immediately able to drop eight pounds from my weights just in the class. I have dropped an additional four pounds since the class by remembering what I was taught in the class. This immediately made me feel lighter and more graceful and made moving easier through the water which translated into less air consumption and longer and more enjoyable dives.
  7. Trim Down – We already discussed the need for being streamlined in the water and how it saves your air consumption, this also applies to your gear. Strap all of your gear as close to your body as possible, or secure it in your BCD pockets. This will do a lot for making you more hydrodynamic which will make it easier to swim through the water with less resistance. As for equipment, if you don’t need it for the dive you are on, don’t carry it with you.
  8. Dive, Dive, Dive – Air conservation comes naturally with the more comfortable you are in the water and the best way to get more comfortable in the water is to dive. The more often you dive the more comfortable you will become and the less anxiety you will feel when diving. This translates to using less air and having more enjoyable dives.

  1. Nice article, I wrote a similar article on DiveBuddy.com and trimmed it down to 3 steps: http://www.divebuddy.com/blog/11207/3-tips-save-air-scuba-diving/

  2. Included are a few of the tips that I used to get my air consumption down and get my dive times up from 45 minutes to over an hour now.

    Good diving tips! I will try them out the next time I dive open water.
