DWF Buddy Brief Builder: Have the Conversation Before the Dive

Good buddy communication starts before the dive.

A good buddy briefing does not have to be complicated. It just has to happen.

Before getting in the water, two divers should have a shared understanding of what they are doing, how they are going to communicate, how they will manage the dive, and what happens when something does not go according to plan.

The DWF Buddy Brief Builder, or B³, is designed to help start that conversation.

Sometimes 90 seconds makes a difference

About a decade ago I was back in California for a weekend of diving and was paired with a diver I had never met. We shook hands, chatted on the boat, geared up, and went diving.

It was not until I asked him how much gas he had that I realized we had never reviewed even the simplest hand signals.

Neither of us had done anything particularly unusual. We had simply skipped a conversation that probably would have taken about 90 seconds.

That experience stuck with me, and it is ultimately why B³ exists.

Build your buddy briefing

Work through the questions together. You do not have to select every condition, review every signal, or fill in every optional detail. Concentrate on the things that actually affect this dive.

DWF Labs

Buddy Brief Builder

Talk through the plan together, then generate a short briefing card you can review or print.

Start with the dive plan

1. Dive Basics

What are you actually planning to do?

Units

2. Buddy Roles

Make task ownership explicit.

3. Gas Plan

Confirm the breathing gas, the usable limits, and how the team will manage it.

4. Entry & Exit

Know where the team forms and where it finishes.

5. Navigation

Keep the route description simple.

6. Communication

The exact signal matters less than both buddies understanding it and being able to communicate with the dive leader when one is involved.

There is no prize for using the “official” hand motion. Agree on the meaning, make the signal visible, and confirm that it was understood.

Signals we want to review before entry
Quick hand-signal review

Review only what matters for this dive. The cards below follow the toggles above. They are common examples, not a universal vocabulary; your buddy and any dive leader still need to understand the same meaning.

OK / are you OK?
OK / are you OK?Use the OK sign to ask or answer whether everything is okay. Make eye contact and wait for acknowledgment.
Something is wrong
Something is wrongA common example is a flat hand rocking side to side, then pointing to the problem when possible.
Up / end the dive
Up / end the diveUnderwater, thumbs up means go up or end the dive. Either diver can end the dive at any time.
Low on gas / at reserve
Low on gas / at reserveMany teams use a fist to the chest as a low-on-gas or reserve signal. Agree on the exact trigger and signal before the dive.
Out of gas
Out of gasMove a flat hand side to side across the throat in both directions, then respond using your training and agreed gas-sharing procedure.
Turn the dive / turn around
Turn the dive / turn aroundUse an agreed signal to say it is time to turn the dive and head back.
Stop / hold here
Stop / hold hereUse a clear stop signal to pause, get attention, or hold position until it is acknowledged.
Come here / stay close
Come here / stay closeUse an agreed signal to bring your buddy or group closer, especially in current, low visibility, or busy conditions.
3-minute safety stop
3-minute safety stopAgree how you will signal the stop, stay together for the full 3 minutes, and confirm the final ascent.
Common pressure-signal examples (PSI / bar)

Examples, not universal rules. Pick a system both buddies understand. If a guide or dive leader uses a different convention, make sure you can communicate with that person too.

Ask for gas pressure
Ask for gas pressureTap the open palm of one hand with the fingers of the other, then look to your buddy for the answer.
Show thousands
Show thousandsHold up the number of fingers for your thousands and tap that hand against your forearm or arm several times. The number of taps does not change the value.
Show hundreds
Show hundredsAfter thousands, hold up fingers for the hundreds. Hundreds are held up, not tapped; values above 500 can be shown as two sequential numbers.
Example: 2,800 PSI
Example: 2,800 PSITwo fingers tapped against the arm means 2,000 PSI; then five fingers and three fingers held up means 800 PSI.
Make the signal visible
Make the signal visibleDark gloves can disappear against a dark suit. Move the signal away from your body, use contrast or light when needed, and wait for acknowledgment.

7. Environment

Pick only the conditions that change the plan.

8. Special Equipment & Tasks

Only include gear or tasks that affect the buddy plan.

9. Separation, Problems & Emergency Readiness

Agree on what happens before a small problem becomes a big one, and know where help is.

Quick Emergency Reference

This is intentionally short. Use the site's full Emergency Action Plan when one is provided.

Call the Dive

This is always part of the briefing.

Either diver can end the dive at any time, for any reason. No vote. No underwater justification. No pressure to continue because of cost, travel, the group plan, certification level, or another diver’s preference.

What should dive buddies talk about?

There is no single briefing that fits every dive. A simple reef dive from shore does not need the same conversation as a drift dive, a night dive, a cold-water dive, or a dive involving a DSMB, camera, reel, or other task.

B³ starts with the basics and expands the conversation when they become relevant. That includes:

  • the objective, maximum depth, and expected dive time
  • who is leading and navigating
  • breathing gas and the team’s gas plan
  • entry, exit, and regroup procedures
  • navigation and turn points
  • hand signals and gas-pressure communication
  • environmental conditions that change the plan
  • special equipment and task loading
  • lost-buddy procedures and other contingencies
  • basic emergency-resource information

The signal matters less than the agreement

Divers sometimes get surprisingly wrapped up in which hand signal is the “correct” one. There are certainly common conventions, and knowing them is useful, but the more important question between buddies is simple: Do we both understand what this means?

If a divemaster, instructor, guide, or dive leader is involved, there is another question: Can we communicate with that person too?

B³ includes a quick review of several useful signals and common ways of communicating remaining gas. They are examples, not commandments. The goal is to make sure everyone involved in the dive understands the same language before entering the water.

And remember that visibility matters. A perfectly formed hand signal does not help very much if a black glove disappears against a black wetsuit in poor visibility. Move the signal away from your body, use contrast or light when appropriate, and make sure your buddy actually acknowledges it.

Either diver can call the dive

This is one point I want B³ to reinforce every single time it is used:

Either diver can end a dive at any time, for any reason.

You do not need to win an argument. You do not need to convince your buddy that your reason is good enough. If something does not feel right, communicate it and make the appropriate decision for the team.

A briefing is not a contract requiring you to complete the planned dive. Conditions change. Equipment develops problems. People get cold, uncomfortable, tired, distracted, or simply decide they are done.

Talk first. Then go diving.

B³ is intentionally lightweight. There is no account to create and no reason for a simple buddy conversation to become another administrative exercise.

Use the tool together, review the parts that matter, make sure everybody understands the plan, and then go enjoy the dive.

This tool is meant to help facilitate a conversation between dive buddies. It is not a substitute for your training, applicable site or operator procedures, actual conditions, or your own judgment. Use your judgment and change or end the dive whenever appropriate.
