Buddy Check

Why do a buddy check

Many dive problems start on the surface: a tank valve left closed, a weight belt with the buckle under a strap, a BCD hose not connected or an alternate air source buried behind a pocket. A buddy check catches these before they matter. It also means you know how your buddy's gear works, which you'll need in an emergency: where their alternate air source is, how their weights release and how to inflate their BCD.

The BWRAF memory aid

Many divers learn the steps with the memory aid BWRAF: BCD, Weights, Releases, Air, Final OK. A common phrase to remember it is "Begin With Review And Friend". Other agencies teach different words for the same idea, so use whatever system you and your buddy know, as long as it covers everything.

B: BCD

Check that your buddy's BCD inflator is connected, and test it: press the inflate button to add air and the deflate button to release it. Find the dump valves and make sure they work. Check the tank is secure in the strap and won't slip.

W: Weights

Check your buddy has the right amount of weight and that it's secure. Find how to release it: the buckle on a weight belt, which should be clear of other straps and set for right-hand release, or the handles on integrated weight pockets.

R: Releases

Check every buckle, clip and strap on the BCD is fastened and that you both know how to undo them. Make sure nothing is twisted or trapped.

A: Air

Check the tank valve is fully open. Breathe from your regulator and your alternate air source while watching the pressure gauge: the needle should stay steady. If it dips with each breath, the valve may not be fully open. Confirm the tank is full and, for nitrox, that the mix matches your computer. Find your buddy's alternate air source and make sure it's easy to reach.

F: Final OK

Do a last check from head to fin: mask, fins, computer on and set, lights and surface marker if you need them, and nothing hanging loose. Then give each other an OK.

Agree the dive

The buddy check is also the moment to agree the dive plan: maximum depth, maximum time, the gas pressure at which you'll turn around and the pressure you'll surface with, what to do if you lose each other (usually search for one minute, then ascend and meet at the surface) and the hand signals you'll use.
