Your Air Consumption Is Not a Badge of Honor

There is a very specific moment after a dive when everyone starts comparing gauges.

Someone still has 100 bar.

Someone has 60.

Someone looks suspiciously pleased with themselves.

And suddenly the amount of air left in your tank has somehow become a competitive sport.

Here’s the thing:

Using less air does not automatically make someone a better diver.

Yes, experienced divers often become more efficient over time. Better buoyancy, relaxed breathing, streamlined gear and less unnecessary movement can all help.

But your air consumption is affected by a lot more than skill.

Your body size matters.

Depth matters.

Current matters.

Water temperature matters.

How hard you’re swimming matters.

Stress matters.

Even the kind of dive you’re doing matters.

A larger diver working against current at 25 metres is simply not having the same dive as someone smaller gently drifting along at 12 metres.

So comparing the numbers at the end isn't particularly useful.

What is useful is knowing your own normal.

Pay attention to how quickly you typically use your gas. Learn how different conditions affect you. Check your gauge regularly instead of waiting for your Divemaster to ask. Plan your dive based on the diver who will reach the agreed turnaround pressure first.

And if you'd like to improve your consumption, work on the things that actually make you a better diver anyway:

Good buoyancy.

Good trim.

Relaxed breathing.

Efficient movement.

Comfort underwater.

The goal isn’t to surface with the most air.

The goal is to manage the air you have well enough to enjoy the dive safely.

Your SPG is giving you information.

It is not handing out medals.
