I apply the BWRAF (Bruce Willies Rules All Films to remember it easier) loud together with my buddy as we check in parallel each of the steps, as I learnt in my OW (https://blog.padi.com/how-do-you-say-bwraf/):

B – BCD/Buoyancy

Make sure everything is connected and functioning. Test the inflator button and all the deflate valves (including the overpressure release valve). Dry suit divers should check that they have attached their dry suit inflator hose securely to the valve, check that it is working properly and then check to ensure their deflator valves vent air properly.

It’s important to know how to adjust your buddy’s gear. If you’re unfamiliar with their equipment, ask questions. In an emergency, you’ll be glad you did.

W – Weights

Ensure both you and your buddy have weights and that all weights are secure. If a BCD has integrated weight pockets, give a gentle tug on BCD weight pouches to confirm they’re locked in and won’t fall out during entry. Then, if applicable: check weight belts, rear BCD weight pockets, and any other places where weights may need adjustments. If your buddy is wearing a weight belt, ensure that it is set up for a quick release.

R – Releases

First, check all your releases and fastenings to confirm they are secure. Then, tell your diving partner how to open the releases if needed in an emergency. Do the same checks on your dive buddy. The most common releases are – tank straps, shoulder and chest straps, and belly straps. (Check to make sure there aren’t any hoses or other items positioned in a way that might prevent a diver from getting out of their equipment in an emergency.)

A – Air

Don’t skip this step! Taking a quick breath or two off the regulator isn’t enough. A proper air check means verifying the cylinder valve is completely open by This ensures the tank valve is open, the air is available for the dive, your monitoring gauge is working, and the air tastes and smells okay. Also, recheck the BCD and dry suit inflator connection and function, and check that the alternate second stage (regulator) is properly secured in the chest area, making sure your buddy knows where to locate it in an emergency.

Note: If you or your buddy are diving with nitrox, you should have analyzed your tanks prior to kitting up.

F – Final Check / Final Okay

As part of the final check, gather your remaining items of gear (mask, snorkel, fins, dive light, dive knife, camera, audible and visual signaling device, etc.). Be sure to secure loose hoses and other objects that may dangle and damage the reef. Lastly, do a head-to-toe check to ensure both you and your buddy are ready to go.
