Buddy diving

Buddy diving is the use of the buddy system by scuba divers and is a set of safety procedures that are intended to improve divers' chances of avoiding or surviving accidents in or under water by diving in a group of two or three divers. When using the buddy system, the group dives together and co-operate with each other, so that they can help or rescue each other in the event of an emergency.

In recreational diving, a pair of divers is the best combination in buddy diving; with threesomes, one of the divers can easily lose the attention of the other two. Groups with more than three divers are not using the buddy system. The system is likely to be effective in mitigating out-of-air emergencies, non-diving medical emergencies and entrapment in ropes or nets. When used with the buddy check it can help avoid the omission, misuse and failure of diving equipment.

In technical diving activities such as cave diving, threesomes are considered an acceptable practice.
