A buddy check is most useful when it exposes different assumptions. Divers may use unfamiliar releases, different computers, long hoses or integrated weights even when both are experienced.
The conversation should be specific enough that either diver can act without inventing a plan underwater.
Build a shared picture with your buddy
Goals
Discuss what each person expects from the outing.
Equipment
Resolve unfamiliar features before the activity.
Communication
Agree the meaning of signals and the briefing.
Changes
Discuss how the team will respond when the plan changes.

Equipment and gas
Confirm cylinder pressure and gas, releases, inflation sources, weights, alternate gas and computer settings.
- analyse and label Nitrox
- agree minimum and turn pressure
- check valves are fully usable
- identify cutting devices
- confirm SMB and reel ownership
The dive plan
Agree leader, route, depth, time, separation procedure, ascent reference and reserve. State personal limits or concerns before entering.
- who leads and who navigates
- where the turn occurs
- lost buddy duration
- low-on-gas signal and response
- surface pickup or exit
Make calling the dive ordinary
Either diver can end the dive for any reason. Saying that aloud reduces the pressure to justify discomfort underwater.
Ask your buddy to show you how their weights release and where their alternate gas is—not merely point at it.
Common questions
Do experienced divers still need buddy checks?
Yes. Familiarity with one's own equipment does not create familiarity with a new buddy's setup or assumptions.
What is the best buddy-check acronym?
Use the current method taught by your agency, but make sure it covers releases, air or gas, buoyancy, weights and the final equipment check.
What should happen after separation?
Agree the procedure before the dive and follow local/operator rules. A common approach is a brief search followed by a controlled ascent, but the exact plan must be understood in advance.
