There’s nothing quite as frustrating as having to surface sooner than you’d like with a good amount of air still left in your tank because your buddy ran out before you. And, let’s be honest, it’s not much fun being the kill joy that used their tank too soon either. So here are 5 tips for saving air when scuba diving and making your tank take you further.
Check our graphic guide to saving air when scuba diving:
Don’t let yourself get too cold
If you let yourself get too cold, you’re going to use air more quickly. The science behind it? If you’re uninsulated, your body heat effectively warms the water around you. This, in turn, speeds up your metabolism and that burns up more energy and increases the rate at which you use up oxygen in your body. Stay insulated and warm and you’ll help to make your tank go further.
Drop unnecessary weight
If you’re carrying more lead than you need, not only will it make buoyancy control more difficult, but you’ll also consume more air. That’s because you’ll need to inflate your BC more and that in turn requires more energy (and therefore more oxygen) to move through the water.
Ditch the extra weight and your tank will go further.
Restrict your air flow
Don’t breathe more than you have to. That sounds ridiculous, I know! But if you press your tongue up against the roof of your mouth and breathe this way, there flow is slightly restricted. This means you will ultimately breathe less air with each inhalation – perfect for saving air when scuba diving.
Faster movements require more oxygen. So slow your movements down, avoid unnecessary jarring of arms and legs and you’ll conserve air far better when scuba diving.
Keep on diving!
If at first you don’t succeed, try and try again. Practice makes perfect with saving air when scuba diving. So consciously set out to get an extra minute here and there and over time, you’ll be able to extend the time your tank will last you.
