height of the diver. This is the regulator that is donated to a diver who is out of air. The "secondary" or "backup" regulator is then reserved for the donor diver and is on a short hose, suspended just under the chin by a "necklace" that can break free in an emergency. The principal advantage is that the diver who is in trouble receives a regulator that is known to be working and provides breathing gas appropriate for the current depth—and quite possibly gets air more quickly than if the clipped off octopus were donated. Donation of the long hose is particularly beneficial for cave and wreck penetration diving where divers sharing air may need to pass through small openings, as the hose length lets them swim in single file where necessary. The length of the hose also allows the divers to swim side-by-side or one above the other in all possible arrangements. Another advantage is that the secondary regulator stows out of the way, protected from strong water flow, contamination and snags, and where the diver can notice if it leaks—but remains accessible without requiring the use of hands, as divers can pick up the mouthpiece by dipping their chin. This arrangement is slightly more cumbersome to use and requires greater skill to wear, deploy and recover. Benefits may not outweigh disadvantages for open water divers in relatively low hazard conditions.

octopus second stage is usually stowed in an easily located, accessible position and is easily detachable from the device that holds it. Most recreational agencies recommend or specify that this position be in the "Golden
Triangle" drawn between a divers chin and nipples. The octopus hose is usually made long enough (1.2 metres (4 ft)) so that the divers are not inconveniently crowded against one another when the octopus regulator is in use. The procedure to provide the octopus is that the donor diver hands over the octopus—but if a buddy does not notice the buddy’s distress, the out-of-air diver has been taught to take the stowed octopus. An advantage with this method is that donor handover is consistent in both octopus handover and for handover of any independent bailout device such as a removable pony bottle. As part of pre-dive checks, the team should review the procedure for handing-over or accessing the octopus in out-of-air emergency. In recreational diving, if good gas management practice has been followed, either buddy should have sufficient air for both to safely ascend to the surface, even if the emergency occurs at the end of the dive. This may not be the case where an unplanned decompression obligation exists.

diving for children. Initiated by PADI, in an effort to expand scuba diving into the realm of becoming a “family activity” like skiing, the certification of children has been adopted by most other recreational diving agencies with their own diving programmes for children. These typically include two levels, depending on the child's age. PADI has six courses/levels for children, in which a child from the age of 10 can become a buddy diver in open water situations. The other buddy in this team can be a certified parent or a dive professional. Serious concerns have been expressed about this general policy of having child buddies, among the concerns is the mental anguish and psychological damage that may be caused to a child who fails to rescue a buddy parent. The first child buddy death in
British waters occurred in 2008. The first double fatality of a buddy pair in which one diver was a minor occurred with a British father and son in Gozo in 2006. Proponents of dive training for children point to the great enjoyment and sense of wonderment the children feel when introduced to the underwater world and point out that other family sporting activities also have unfortunate incidents of serious injury to children.

case of an emergency, performing a rescue if the diver is unable to manage an emergency, and assisting the diver out of the water after the dive if appropriate. This system can mitigate high-risk emergencies when performed to the standards. This is not a controversial issue. This level of assistance requires the buddy to be familiar with the diver's equipment in detail, including the adjustment of harness and emergency release of weighting systems, control of inflation and dump valves, siting and attachment of secondary demand valve, knife and any other safety equipment. Recreational divers may be trained in some or all of these skills depending on their certification. The buddy system is not considered sufficient on its own. Dive planning, medical and physical fitness to dive, suitable and correctly functioning equipment, appropriate surface support, skills, experience and knowledge are all part of the diving safety system. To be fully effective, the buddy system is applied to an agreed dive plan, with effective communications, the willingness and ability to assist each other in all reasonably foreseeable circumstances associated with the dive plan, and the will to follow the dive plan.
632:
any one of the divers fails to put in the effort, putting the burden on the remaining diver who takes the responsibilities more seriously. Familiarity with the environment and the very low incidence of life-threatening accidents is likely to lead to a confidence that there won't be a problem on any given dive, so the divers may pay less attention to good buddy practices, and this may become habitual. This may be exacerbated by the divers being strangers thrown together by chance and the whims of the divemaster, who have no real interest in each other, and whose reasons to dive may be incompatible. Pairing an explorer with a macro photographer often annoys at least one, probably both, if they comply with recommended buddy diving practices. Many nominally buddy dives effectively become solo dives soon after entering the water, with the buddies occasionally checking for the presence of each other and often being beyond direct view of each other. In spite of this, very few of these divers die as a consequence.
249:
the less experienced diver is not an ideal buddy to the more experienced diver, who must take an unbalanced share of responsibility, and this constitutes an informal training scenario. Compatibility problems are magnified when divers who do not know one another are paired off as buddies by the dive operator. Numerous harrowing stories abound about diving with "the tail-end-Charlie" or the "buddy from hell" out of such practices. The "perfect buddy" is a long term friend or acquaintance, a partner who matches one's own high level of diving skills, who has the same interests, the same stamina and fitness, and who enjoys the companionship in sharing enjoyable diving. Although the principal reason for instituting the buddy system is the mitigation of the risks in diving, the sharing of diving experiences and the enjoyment of being paired together with a friend, family member, or keen fellow enthusiast while on a dive ranks very highly in the reasons many divers enjoy the recreation of scuba diving.

particularly liable. It is recommended now that buddy divers carry insurance that provides coverage of themselves against legal actions by buddies, particularly if diving takes place in those countries where a culture of litigation may exist. This is particularly necessary for scuba diving professionals who earn a living in the recreational diving industry, when they "buddy-up". More experienced or more qualified divers may also unreasonably be expected to bear a higher duty of care for their less qualified buddies, and therefore a serious burden can be placed on a vacationing diver asked to buddy up with a stranger, especially in litigious jurisdictions, and specially if either diver is not as competent as their certification and experience may suggest.

such as maximum depth, route, duration, critical breathing gas pressures and decompression plan, who will lead and who follows, buddy separation procedures, etc. and the dive objectives: is it general sightseeing, to view a wreck, photography, hunting a type of game?. In technical diving, these objectives often become much more complex and very specific – penetration of a particular part of a cave to a particular point. Many diving objectives require allocation of specific roles and responsibilities. For example, in lobster hunting on the west coast of
America, buddy teams often split into assigned roles of hunter-game catcher, and stower-catchbag carrier, and overall dive success depends on teamwork and carrying out assigned roles.
214:—began programmes to train swimming enthusiasts in this new aquatic pastime, and began to codify what they believed were proper practises for this expanding sport. The YMCA considered the buddy system a useful corollary to the "never swim alone" rule of their swimming and lifesaving programmes. Cousteau himself independently implemented a buddy system from the earliest days of exploratory diving after a number of harrowing diving incidents. The buddy system did have some useful aspects: cross checking of equipment before dives, facilitating assistance for possible entanglement problems or equipment failures, and enhancement of the social nature of diving. The YMCA remained a major force in the development of

with incidents of injury below several other "risk" sports such as football, horse riding or even tennis. Yet unlike these other sports, scuba divers are in a hostile environment for which humans are not adapted, breathing from a portable and limited capacity life support system. Under these conditions, fatality is always a possible outcome, as even simple equipment or procedural problems can be mishandled. In dealing with this reality a number of major concerns about potentially inherent flaws or negative impacts that can exist within the buddy system have been identified. Few, if any, of these problems, are defects in the concept of the buddy system, they are problems with the application of the system.
119:
of rendering assistance to the other in any reasonably foreseeable contingency, and willing to do so within the scope of acceptable personal risk. The buddy divers are expected to take mutual responsibility for the safety of the buddy pair above and below the water, and this responsibility commences when the divers prepare for the dive. It is assumed that it is unlikely that both divers will experience the same problem at the same time, allowing the diver not in trouble to assist when the other diver has difficulties. This mutual responsibility is usually not required by legislation, is entirely voluntary unless required by terms of service of a service provider, and generally cannot be enforced.
666:
against liability risks and must act to minimise the cost of this insurance for both themselves and their operatives. The buddy system, beneficial as it can be in enhancing diver safety, has the legal effect of creating an involved intermediary person between the certifying agency and any injured party, an intermediary who could be easily identified as not having provided "duty of care" if an accident occurs. This may afford a legal cushion for the agency, or trainer, or boat - but it is not exactly good news for someone acting in the role of a buddy. The more skilled the buddy partner, the more these duties of care may be assumed to increase, often without legal justification.
450:
taught fairly consistently by recreational diver training agencies, but it is not compulsory and variations in this procedure may be agreed upon by the divers during dive planning. Compliance is variable, as ascent in most cases implies termination of the dive, which may not be welcome to either party. Loss of buddy contact is commonly reported in diving fatalities, but in many cases it is not clear whether loss of contact was a cause or an effect of the fatal incident. In overhead diving, the team member separated from the guide line is considered lost, as the guide line is the means of finding the way out, and the procedure is different.
636:
deal with any real diving problems. This creates a situation where divers become dependent on the "security blanket" of being with another diver. The reality may be that the buddy diver on whom many divers depend is often no better able to handle an emergency than the dependent buddy. The fostering of this false security by diving agencies that overemphasise the effectiveness of the buddy system, develops a sense of complacency in divers about their capability to deal with these problems, a capability which they often do not have. This complacency holds divers back from focusing on improving their lifesaving skills and capabilities.

be entirely unfamiliar with each other. In this system, especially in large groups, poor visibility or strong currents, the weak, inexperienced, or inattentive individual divers can easily become detached from the group and lose the protection of stronger or more competent divers in the group. Communication is often difficult in these groups leading to increased risk, but they are not left with sole responsibility for a stranger of unknown competence.

been described as " the untrained diver", "the high-flyer", "the falsely confident diver", "the angry diver", or "the buddy from hell". The bad buddy problem is compounded by training that compels a diver to "stick with his buddy" no matter what, leading to the situation that it is the bad buddy who sets the criteria of how (badly) the dive is carried out. Both the solo diving and the buddy diving community have come to a similar conclusion on how to best address the issues of safety in both systems – self-sufficiency. In the buddy system, this means that

When the system fails, it is generally because one of the divers does not fulfill his or her responsibilities as a buddy. If one of the divers is incapable of providing the expected assistance the buddy system has already failed. With professional divers, buddy responsibility may vary and will be specified in the code of practice, operations manual, and dive plan. Each diver in this case must be capable of fulfilling their responsibilities according to the dive plan.

The disadvantage of a buddy line is an increased risk of snagging and entanglement. Divers may need to disconnect the line quickly at either end in an emergency, which is done via a quick release mechanism or by cutting the line, both of which require at least one free hand.
