Signals for an unfamiliar buddy
Hand signals only help if both divers mean the same thing.
Safety and training
General field notes, not a dive plan. Stay within your training, follow local site rules and the operator’s briefing.
Field observation
Before entry, agree how to show remaining gas, turn pressure, a problem, stop and ascent. Confirm how the guide will signal to the whole group and how you will answer.
A practical approach
Rehearse the important signals face to face; if a message is misunderstood underwater, stop and clarify rather than guessing.
Dive-day checklist
Before you go
- Check local conditions and access rules
- Agree limits and the exit with your buddy
- Stop or change the plan if conditions differ
General guidance only. Follow your training, the dive operator’s procedures, and each manufacturer’s current instructions.
Ask the dive guide
Personal guidance for your next dive
Describe a dive scenario or an equipment-care question. The guide answers in your language and points you to relevant journal articles.
General educational guidance only. It is not medical advice, emergency instruction or a replacement for training, certification, manufacturer instructions, your operator's briefing or your dive plan.
