Note: This article is written for recreational divers. Technical and team divers often use different protocols. This is not a replacement for those procedures.

Most divers learn a buddy check during Open Water training. They understand why they should inspect their equipment and know how to help their buddy. Yet on recreational dive boats, I rarely see anyone initiate the process. During my first 50 non-class dives, with 20 different buddies across multiple countries and dive sites, not one of those divers initiated a buddy check with me.

That doesn't prove everyone behaves this way, and it doesn't mean checklists are useless. It did make me wonder why a procedure taught so consistently could disappear as soon as there was no instructor expecting us to perform it.

Why the Formal Check Gets Skipped

BWARF is a perfectly reasonable way to check equipment. The difficulty isn't necessarily the checklist but the circumstances in which two strangers are expected to use it. The boat is busy, divers are getting dressed, and nobody wants to be the person who interrupts everyone to begin a formal exercise.

In human factors, this is part of the gap between Work As Imagined and Work As Done. The imagined version is orderly and unhurried. The actual version has competing demands, social pressure, and a buddy you met five minutes ago. A good procedure can still fail when nobody initiates it.

I've had more success working the important questions into the things we're already doing: talking about the site, assembling equipment, and getting ready to enter. That changes how the check begins, not what needs to be verified.

The 4G Framework

I use four prompts to guide the conversation. This isn't an alternative set of equipment checks, and I don't announce the acronym to my buddy. It's a reminder of what I need to understand before we dive.

  • Goals: What are we hoping to do, and are we comfortable with the conditions and each other's expectations?
  • Gear: Where are the alternate regulators, inflators, dump valves, and weight releases, and how do they work?
  • Gas: What are we breathing, what pressure are we starting with, and is our equipment delivering gas properly?
  • Go: What's the route, depth, turn pressure, ascent plan, and lost-buddy procedure?

Goals and Go serve different purposes. Goals tells me whether we want the same dive; Go establishes the practical plan and how we'll end it. These questions fit into ordinary conversation far better than reciting four headings at someone.

How It Works With Someone I've Just Met

I generally start with a little conversation while we're getting ready. What brought them on the trip? What are they hoping to see? It isn't an interview, but it gives us a way to talk and may reveal concerns about the conditions or the plan. That first exchange helps build the psychological safety needed to ask questions or speak up later.

As they assemble their gear, I ask about what I'm looking at. If they have integrated weights, I want to know how the releases work. If their alternate regulator is secured somewhere unfamiliar, I ask them to show me. Then I explain my own equipment. I often dive with a long-hose configuration, so I demonstrate which regulator I'll donate and where my backup is located. It's much easier to understand when someone shows you.

I want to know these things because I might need to help my buddy, and because I may need their help. Approaching the conversation that way makes it about our mutual safety rather than an opportunity to inspect or criticize someone else's equipment.

Gas and planning questions follow naturally. I might mention that I'm using nitrox 32, ask what they're breathing, and compare starting pressures. We still need to agree when to turn, how to ascend, and what happens if we become separated. The point isn't to conceal a checklist inside small talk. It's to establish a useful working relationship before either of us has to depend on the other.

How I ask matters. Opening with questions about their highest certification, dive count, or training background can sound like an examination. Telling someone how they should rig their equipment or what class they ought to take is an even quicker way to end a conversation. I'm trying to learn whether we can dive together, not establish which of us knows more.

Conversation Isn't a Function Check

A friendly discussion won't tell me whether a cylinder valve is fully open, a BCD inflator operates, or a computer is set for the gas being used. Knowing where a buddy's alternate regulator is secured doesn't prove it works. Those things still require actual checks, regardless of how comfortable the conversation feels.

Before entry, I want the gas supplies and regulators verified, BCD functions tested, releases understood, and the dive plan agreed. If we're doing a bubble check after entering the water, I raise that beforehand too. I've covered the physical steps separately in Pre-Dive Checks. The 4G approach is how I make those steps easier to initiate with somebody I've just met, not a reason to omit them.

When a Buddy Doesn't Engage

Some divers enjoy talking through their equipment; others respond with little more than a nod. That's fine. I'm not looking to make a new friend on every dive, and I don't need an extended briefing if we can establish the important facts quickly.

But there's a difference between someone who dislikes conversation and someone who won't cooperate with essential checks or planning. If I can't establish how we'll share gas, release weights, or handle separation, I have to decide whether this is a buddy I can safely dive with. Social awkwardness isn't a good reason to enter the water without information I might need in an emergency.

With regular teammates, I prefer a more comprehensive GUE-EDGE briefing. With an insta-buddy, I adapt the conversation to the setting, but the standard remains the same: we both need to understand the equipment, agree on the dive, and know what we'll do if something goes wrong.
