Open-Circuit Etiquette with Closed-Circuit Divers
If you are an open-circuit diver, it is becoming increasingly common to find yourself on a boat with a rebreather diver; or perhaps you may even get assigned a rebreather diver as a buddy. Like you, the rebreather diver has been trained to do a few minutes of setup and checks on their equipment before they dive. Often, another diver will approach and begin asking questions at just this moment. The rebreather diver really would like to talk about their equipment and answer questions, but part of their training included a reminder to avoid becoming distracted during their checks. Help them out by waiting until you see their setup is completed. If you are assigned a rebreather diver as a buddy, they will need to have a brief safety protocol discussion with you as there are some differences from your open-circuit training.
