When The Pressure Is On

Inside of the shipwreck the water is calm, it’s inviting when compared to the washing current outside.
We go in.
The darkness consumes us. Our lights although powerful are absorbed by the silt and the steel. A guideline reminds us of our exit while our bubbles slide up the walls like glass beads heading to the surface which is actually toward the bottom of this upside down shipwreck. 
 
All it takes is a poorly controlled kick, someone’s fin brushes the bottom… a century of rust and silt come bellowing down and in one breath, your entire world turns to brown… it’s all you can see.
 
The visibility vanishes. The space that had felt huge becomes claustrophobic and tight. The instinct to move, to escape, to “do something” immediately echoes off the steel with a loud pulsating urge to move and breathe fast.
 
But we don’t rush. No one spirals. Hands find the line, signals are exchanged, and the team moves slowly and deliberately, following the plan we had practiced over and over again.
 
On the surface, you might think, “We really rose to the occasion down there.”
 
But that’s not what happened.
 
In reality, we didn’t rise at all. We fell… we sank, to the level of our preparation. 
 
It’s not just a catchy quote. It’s a reflection of how human beings actually behave under stress. And understanding this principle is key to becoming a capable and confident diver.
 
It’s why continued practice after a course like The Essentials of DIR Diving matters so much. It is why a deeper grasp of Human Factors transforms not only how you dive, but how you think… before, during, and after a dive.
 
Experience Shapes What You See
 
In his article, “The Importance of Experience”, Gareth Lock explores how experience, awareness, and decision-making interact under uncertainty. He poses four questions that every diver… and really, every human under pressure, must wrestle with:
   1.         How do we know what to pay attention to?
   2.         How do we know how much attention to pay to that task?
   3.         How do we really make decisions in uncertain situations?
   4.         How do we know we made the right decision?
 
These questions form the backbone of situational awareness and sound judgment. Let’s look at how they play out underwater, and how The Mott Underwater Method, DIR Diving, and Human Factors make all the difference. 
 
1. What to Pay Attention To
 
Underwater, the environment bombards you with information… light signals, silt movement, gauge readings, currents, sounds, your breathing rate, your teammate’s position. All of them working hard to steal your awareness.
 
The experienced diver doesn’t get lost trying to see everything. Instead, they see what matters. They’ve learned to filter out the noise that isn’t relevant at the moment. That ability doesn’t come from natural talent, it comes from repetition, feedback, and mindful practice.
 
When the pressure is on, you won’t invent a new way to filter the noise from a new problem. You’ll only notice what your preparation has taught you to notice.
 
2. How Much Attention to Pay
 
Focus is a limited resource. Spend too much of it on one task and you can miss something critical elsewhere. You can’t lock your attention away on the one task at hand when you’re diving. 
 
Through training and simulation, divers learn how to balance that attention. How much to devote to buoyancy, navigation, communication, and monitoring. This is calibration, and it’s built through deliberate, repeated experience.
 
When the pressure spikes, the diver who’s practiced this balance maintains situational awareness. The one who hasn’t, loses it… and that can be disastrous. 
 
3. Making Decisions in Uncertainty
 
Every dive involves ambiguity, there is always some trust and assumption, a bit of hope. You rarely have perfect information. you have patterns, hints, and probabilities.
 
The more experience you’ve built, the more patterns your brain can recognize. This is why failure based scenarios are so important in the Mott Underwater Method of training. Navigation is so much more than looking at a compass to stay on course… it’s all the other stuff. Knowing that you can and most likely will lose track and being prepared for that, having seen enough scenarios that your intuition becomes informed.
 
Under stress, you won’t build a perfect plan from scratch. You’ll fall back on the patterns you’ve seen before, the mental “movies” you’ve watched in re-runs. That’s why repetition, simulation, and debriefing are critical parts of real preparation.
 
4. Knowing You Made the Right Decision
 
The last question Gareth poses is perhaps the most important: how do we know we made the right decision?
 
We know because we reflect. Because we debrief. Because we create space to analyze what worked, what didn’t, and what we missed.
 
Without that reflection, without that feedback, our learning is suspended. We end up repeating the same mistakes, assuming that survival equals success. But survival is just the start. True progress happens when you actively close the feedback loop.
 
Situational Awareness- A Pillar of DIR
 
Situational awareness is not just a buzzword. It can’t simply be memorized. It has to be burned into your soul underwater through the Laws of Intensity and Effect. And even still it is fragile to outside forces, no matter how well practiced you are. 
 
Outside forces like-
 
Cognitive load: when you have too many tasks competing for attention.
Fatigue: when the situation or environment mentally or physically exhausts your overall perception.
Automation: when you fall into a mindless routine and miss obvious changes.
System design: when simple communication or equipment use is taxed and now an easy job becomes complex and confusing. 
 
Good preparation isn’t just about drills. It’s about managing these limits, designing your dives and systems to keep awareness alive when stress climbs. This is why The Essentials of DIR Diving becomes so important for any diver who wants to take ownership of themselves underwater. 
 
The Bottom Line
 
When the visibility drops, when equipment fails, when time and gas start slipping away, unlike the fable suggests… you will not rise to the occasion.
 
You will fall to the habits, awareness, and decision-making patterns you’ve built through your training and experience.
 
That’s why continued, critical-skills education isn’t a luxury, it’s Essential.
 
Your Next Steps
 
If this resonates with you, take the next step in your development as a diver:
 
Join my next Essentials of DIR Diving class — build the foundation that holds steady under pressure.
Attend the next Human Factors in Diving course — learn how humans actually make decisions, communicate, and err.
Work with me one-on-one through coaching — refine your skills, strengthen your preparation, and build the confidence that shows up when the pressure is on.
 
Because when it all hits at once… the visibility, the current, the stress, your gas, your time… you won’t become someone new who rises to something better. 
 
You’ll become exactly what you’ve prepared to be.
