Step 6: Situational Awareness and Problem Prevention

Step 6 of 10 to Boost Confidence, Dive Safely, and Empower Nervous Divers

Over the past month and a half, we’ve focused on building confidence through understanding dive anxiety, sharpening your skills, and enhancing communication underwater. This week, we shift our attention to a crucial but often overlooked aspect of diving: situational awareness and problem prevention.

Situational awareness is more than just knowing where you are—it's about understanding the environment, your physical state, your gear, and your buddy’s condition at all times. Good situational awareness allows you to anticipate problems before they happen, which gives you the power to respond calmly and effectively.

Paying attention to their surroundings, a buddy team can enjoy a long dive and safely execute their dive plan.

Why Situational Awareness Matters

Diving is a dynamic activity—currents shift, visibility changes, and marine life can surprise you. It's easy to get so focused on the beauty of the underwater world that you lose track of depth, air supply, or your buddy's location. But awareness isn’t just about avoiding trouble; it’s about maximizing enjoyment while staying safe.

Strong situational awareness enables you to:

✅ Monitor your depth and air supply consistently

✅ Recognize changes in the environment

✅ Stay connected with your buddy

✅ Adjust your dive plan in real time based on changing conditions

✅Prevent minor issues from escalating into emergencies

Poor situational awareness, on the other hand, can lead to missed signals or communication, rapid air depletion, dangerous depth changes, and increased risk of decompression sickness (DCS).

Building Situational Awareness

1. Develop a Pre-Dive Checklist

Preparation is key to avoiding problems. Before every dive, run through a personal checklist:

• Is all your gear functioning properly?

• Do you know the dive plan and emergency protocols?

• Are you mentally and physically prepared for the dive?

Pre-dive preparation allows you to start the dive with confidence and reduces mental clutter, leaving you more focused on the dive itself.

2. Keep Track of Depth, Time, and Air Supply

It’s easy to get caught up in the excitement of a dive, but you should check your depth gauge, dive computer, and SPG regularly. A good rule of thumb is to check your air at at least every five minutes and certainly after any depth change or significant exertion.

✅ Set a Personal Air Limit: Agree with your buddy on a minimum air level at which you will begin your ascent. Stick to it—don’t let the excitement of a great dive override your safety limits.

✅ Monitor Your Depth: Sudden depth changes not only increase nitrogen absorption but also cause rapid air consumption. Keep a steady eye on your dive computer and adjust your depth gradually.

3. Maintain Buddy Awareness

Situational awareness includes your buddy. Stay close enough you could assist them with anything that may come up and communicate frequently with hand signals. If your buddy seems to be distracted, breathing heavily, or losing focus, take the initiative to check-in.

✅ Make eye contact frequently. A quick and simple “OK”👌 signal can prevent confusion and build confidence.

✅ If your buddy gives you the “problem” or “not OK” signal, stop immediately and assess the situation.

✅ If you lose visual contact, follow the agreed-upon procedure to regroup at the predesignated point or at the surface

4. Scan the Environment Continuously

Good situational awareness includes understanding the changing dive environment. Pay attention to:

• Strength and direction of current

• Marine life behavior (are fish schooling unusually?)

• Light changes (indicating depth changes or cloud cover)

• Bottom composition and depth

Knowing what’s happening around you helps you anticipate and adapt before problems develop.

5. Manage Task Loading

Carrying a camera or other equipment can pull your attention away from critical dive factors like depth and air supply. Keep it simple—if you feel overwhelmed in any way, pause, breathe, and refocus.

• Take a moment to stabilize yourself.

• Put down the camera or let go of the task.

• Regain control of your buoyancy and awareness before proceeding.

6. Avoid the ‘Lack of Accountability’ Trap

An all-too-common mistake I’ve seen among divers—especially newer ones—is over-relying on their buddy or dive leader to manage the dive for them. It’s easy to fall into the trap of thinking, “My buddy will tell me when to turn back” or “My instructor will signal me if I’m low on air.”

This happens when a diver leans too hard on their partner for things like:

❌ Monitoring their air and depth

❌ Navigating the site and deciding when to turn around

❌ Setting up their gear and conducting pre-dive checks

❌ Managing the safety stop

When these divers suddenly find themselves without that experienced buddy—or when their buddy gets distracted or away from their immediate proximity—panic sets in. They face a moment of “Oh shoot! Now what?”

This is why self-sufficiency is so important. A confident diver is one who takes responsibility for their own dive. You should always know:

✅ How much air you have left

✅ How deep you are and how long you've been underwater

✅ How to navigate back to the boat or shore

✅ When it’s time to ascend

If you take ownership of these elements, you’ll avoid the stress and uncertainty that comes from relying too much on someone else. It’s great to trust your buddy—but not to depend on them for your safety.

A Lesson From Real-Life

I once had a dive with a friend that perfectly illustrates the importance of situational awareness. We were about 45 minutes into a dive, finishing up our safety stop in the shallows, with around 900 psi left in our tanks. Suddenly, a turtle descended from the surface after a breath, and my buddy—who had a camera in hand—couldn’t resist following it.

Despite my banging on my tank and attempting to get his attention, he was so focused on getting the perfect shot that he ignored me entirely. He followed the turtle down—deeper and deeper—until he was nearing 100 feet. I had no choice but to swim down, grab his fin, and practically pull him back up.

By the time I got his attention, he was low on air and dangerously close to needing a shared ascent. We had to make an extended safety stop before surfacing, and he finished the dive with just over 100 psi left. Had I not caught him in time, we might have had to share air or even skip the safety stop—either scenario could have led to serious complications.

So what’s the lesson here? It was a cute turtle—I'll give him that—but no amount of blurry pictures(they were all out of focus🤦‍♂️) is worth compromising safety. That moment was a classic example of how easy it is to lose situational awareness when you get hyper-focused on one element of the dive.

Your Challenge This Week

1. Build Your Own Map

Go to a park, hiking trail, or even an unfamiliar neighborhood and walk around for 10–20 minutes. As soon as you return, try to draw a map of the site from memory. Include static landmarks—like trees, signs, or benches—rather than animals or people that may not be there next time.

• No judgment if your map looks like a toddler’s finger painting, congratulations on getting out and doing the exercise—you’ve passed the first test. Keep practicing. They will get better.

  
  

• Don’t go back and “fix” your map. NO CHEATING! That random lump you drew could be a rock… or a really confused squirrel.

• Next, we are going to take a friend or loved one,(bonus points if you take your dive buddy) show them your map, describe the site, and go walk it together. See if they have any thing they notice to improve your map.

➡️ This exercise teaches you to focus on fixed reference points, which is exactly how you should navigate underwater. Fish, sharks, and other creatures won’t be in the same place next time—but a coral head, a boulder, or a wreck will be.

2. Drive With Awareness To Learn How To DIVE With Awareness

Next time you take a drive, take note of how often you check your mirrors, speed, and signals. Notice how you constantly adjust based on what’s happening around you.

• Have fun with it. Channel Your Inner Spy: Pretend you're being followed by secret agents and need to stay aware at all times. 😎 Dramatic sunglasses are optional.😎

  
  

• If you realize you haven’t checked your mirrors in five minutes, you might as well be driving blindfolded. The same could be said when it comes to turning around to look for your buddy.

  
  

• Use your blinker like you’ve got something to prove—because you do. Again this is how you communicate with others and let them know what you are doing. Communicate with your buddy!

  
  

➡️ Situational awareness in diving is very similar process—it’s about gathering information, adjusting your behavior, and staying ahead of the situation. The more you develop this habit on land, the more natural it will feel underwater.

Final Thoughts

Situational awareness is one of the few things we, as divers, can actively change BEFORE or DURING our very next dive. Unlike skills that take time and practice to develop, improving your awareness is simply about paying attention—being present in the moment and tuned into your surroundings. This shift alone can help you feel more relaxed, more in control, and more confident in the water.
