Diving is a sport where the margin for error is considerably smaller than most recreational activities. Equipment failures, missed safety checks, and communication gaps can escalate underwater in ways that rarely apply on land. The buddy system exists precisely because two divers working together catch problems that one diver alone might miss. At the centre of the buddy system is a pre-dive ritual that every certified diver learns during their Open Water course but not every diver takes seriously enough: the buddy check.
What Is the Buddy Check?
The buddy check is a systematic pre-dive inspection that dive pairs conduct on each other's equipment immediately before entering the water. It covers the essential components of both divers' gear, confirms that everything is assembled and functioning correctly, and ensures that both divers know how to operate each other's equipment in an emergency. It takes approximately two minutes to complete and can prevent accidents that have caused fatalities in the diving community worldwide.
The buddy check is most commonly taught and remembered through the acronym BWRAF, sometimes memorised using the phrase "Begin With Review And Friend." Bwraf scuba checks are standard practice at reputable dive schools, and any diver who has not performed one before entering the water has missed a critical safety step.
Breaking Down BWRAF
B — BCD (Buoyancy Control Device) Both divers should inflate and deflate their buddy's BCD verbally and manually, confirming that the power inflator functions, the dump valves operate, and the wing or jacket holds air without leaking. A malfunctioning BCD cannot be reliably remedied underwater, and knowing your buddy's dump valve location before you dive could prove essential in a rapid ascent situation.
W — Weights Confirm that your buddy is carrying the correct amount of weight and, critically, that you know how to release their weight belt or integrated weight system in an emergency. A diver who is overweighted and unconscious on the surface needs their weights removed quickly — you cannot afford to spend time figuring out how to do this when it matters. Bwraf diving protocols make this check mandatory.
R — Releases Go through all the clips, buckles, and fasteners on your buddy's equipment. Know where the shoulder releases are, whether there's a crotch strap, and how the tank band is secured. In an emergency where equipment needs to be quickly removed, fumbling with an unfamiliar buckle costs time.
A — Air Confirm your buddy has a full cylinder (most operators require a minimum of 200 bar for standard recreational dives). Test that the regulator delivers air correctly by breathing from it, locate the primary second stage, and identify the alternate air source. Buddy check diving includes knowing where your backup air is and how to share it.
F — Final Check Step back and visually assess the full equipment assembly. Trailing hoses? Dangling gauges? Unclipped accessories? The final review catches the details that the previous steps might miss — the loose fin strap, the forgotten computer, the open pocket that will flood and slow you down.
Why Experienced Divers Skip It (And Why That's Wrong)
There's a well-documented tendency among divers with significant experience to treat the buddy check as optional — a formality for beginners rather than a meaningful safety procedure. This attitude is both common and dangerous. Dive accident analyses have repeatedly found that equipment failures contributing to incidents were ones that a buddy check would have detected, and that many of the divers involved were experienced individuals who had become complacent about pre-dive procedures.
Fatigue, equipment unfamiliar to one diver in a pair, new gear, or simply an off day where something has been assembled incorrectly are all circumstances where bwraf diving offers a genuine safety net. The two minutes invested before every dive are not a ritual of inexperience — they are a habit of professionalism.
How Dive Schools on Koh Tao Approach the Buddy Check
Quality dive operators make the buddy check a non-negotiable part of every pre-dive sequence. This includes fun dives with experienced divers, not just certification courses. When dive staff conduct buddy checks as standard practice — completing them themselves before every dive and explicitly facilitating them for their guests — they reinforce the habit in ways that classroom instruction alone cannot.
Operators who skip or rush buddy checks in the name of efficiency are making a choice that reduces safety margins. Choosing a dive school that genuinely embeds these practices into its culture is an important factor in selecting an operator on Koh Tao.
Conclusion
The buddy check is not a bureaucratic formality — it is the practical expression of the buddy system that underpins recreational scuba diving safety. BWRAF diving gives both divers in a pair the information they need to assist each other effectively if something goes wrong. Making it a genuine habit, performed carefully before every dive regardless of experience level, is one of the simplest and most powerful things any diver can do to make their underwater time safer.
