Few principles are promoted as universally in scuba literature as the buddy system. From basic certification manuals to slick dive magazines, divers are encouraged to descend only with another. Most published photos show buddy teams exploring together and all responsible dive charters only allow divers to enter the water when teamed with a partner. Unfortunately, despite all this attention to the concept of buddy diving, it remains the single most misunderstood, if not most neglected, practice in scuba.
Essential, the buddy system partners individuals with a shared diving goal. The purpose is to increase the margin of safety for each diver by providing someone to assist in preventing problems and to help should they arise. Capable buddies also share diving tasks such as navigation and flag towing. An extra set of eyes helps spot lobsters and other prey, or just to share a moment of beauty and wonder like we so often experience in the deep. A good buddy may contribute additional skill, expertise, or even gear to make the dive that much more profitable. All of these benefits are realized when buddies honor the right priorities and practices when diving but the sad truth is that many buddies do not provide the support they should once the team descends beneath the surface.
Good buddy practice begins before entering the water, continues throughout the dive, and concludes only after the team is back on the surface, the dive is debriefed, and gear is secured. Predive planning is the best time to share essential elements of the dive, such as goals (i.e. photo, hunting, exploration, or just sightseeing), communications (hand signals and light discipline), navigation, air/depth/time management, and gear requirements. New buddies can share personal experience and training levels to ensure each has an approximation of the other’s abilities and limitations.
Buddies should articulate and agree upon separation procedures during planning. Standard practice recommends buddies search for the other for no more than one minute before ascending to reunite on the surface. This method works and has served many divers well through the years but the plan may require some adjustments according to conditions. In limited visibility situations or when surface conditions dictate, divers may wish to limit underwater search time before ascending. In some cases, a designated meeting point such as a boat, float, or landmark may be practical.
Beach diving buddies add an additional task of remaining available for assistance during surf entry. Wind, waves, and current may complicate the process of getting into the water. It is not hard to lose one’s balance when hit sideways by an unexpected wave. When trying to regain that balance while wearing more than 50 pounds of gear, a helping hand is a blessing.
Once submerged, each diver checks the other for loose straps, unsecured gear, excessive bubbles, and available air. At this point, divers can compare time, depth, and computer settings to allow for maximum synchronization. Only after sharing the "go" signal, should divers begin swimming away from the entry point.
During the dive, buddies should stay in close proximity to each other. Actual distance may differ according to visibility and other factors but a general rule allows a two-second separation. Buddies should always remain within sight of one another, meaning they should swim in such a way that each knows where the other is at all times. Each should occasionally check the other for gear security and retention (particularly loose tank bands and dangling consoles), and for signs of discomfort or unusual behavior. This is especially true on deep dives or when using enriched air, when narcosis and oxygen exposure risks are greater.
At the end of the dive, buddies assist each other in surface navigation, equipment wrangling, and exiting the water. When boarding a boat, one may provide stability or guidance in choppy conditions. When exiting through surf, wave awareness and balance issues are present. Once out of the water, buddies help each other with transporting, rinsing, and stowing gear. Beach divers may need to walk up the beach and through a parking lot, so having a buddy means having help either carrying gear or keeping an eye on it while it is transported in shifts. A post-dive brief completes the dive, with each diver sharing perceptions, experiences, and suggestions for the future.
The list above constitutes a rough outline of what good buddies do before, during, and after a dive. Consistent practice of good buddy skills is probably rooted in the attitude and philosophy of each diver. If a diver believes in the value of having and being a good buddy, that diver is more likely to make the effort to be one.
That brings us to what one should look for when choosing a dive buddy. A wish list for best dive buddy qualities might include the following:
Sound judgment – demonstrates common sense in decision making.
Reliability – can be counted on to show on time, do what they say, and be where they belong.
Safety conscious – knows safety procedures and avoids unnecessary risk.
Skilled – trained and experience to the level required by the dive. Preferably rescue qualified.
Some divers claim they are better off without a buddy than when diving with a bad buddy. They may be right. A buddy who lacks common sense, who consistently makes unsound decisions, who takes unnecessary risks, and who dives without proper training or equipment, is an accident waiting to happen and poses a threat to those nearby. As this is written, authorities are searching for a diver who abandoned his two buddies and has been missing offshore for two days. According to facts related by one of his buddies, this diver should not have been diving at all that day much less in demanding conditions at sea. If that is true, he failed his buddies and they failed him by not stopping a preventable accident.
Every diver is responsible to fulfill good buddy duties and each should take care in choosing with whom to dive. The buddy system works best when divers understand it, respect it, and practice it consistently.
