by MustBTVAs a newly certified diver on the path toward becoming a more advanced and confident underwater explorer, I’ve learned one truth that comes up again and again: mastering the fundamentals is what keeps you safe and helps you grow.
One of the most basic—but often skipped—skills is the pre-dive safety check.
At first, it felt like a checklist I had to memorize for my Open Water test. But now, as I gain more experience and work toward higher certifications, I’ve come to respect this step for what it really is: a proven process that prevents problems before they ever begin.
Whether you’re suiting up with your own gear (like my Mares Bolt SLS BCD and Dual ADJ 62X reg set) or borrowing rental equipment, this is the last line of defense before you descend. And it only takes a few minutes.
BWRAF – The Backbone of a Safe Dive
Most divers are taught the BWRAF acronym early on. It stands for:
- Bruce – Buoyancy (your BCD)
- Willis – Weights
- Ruins – Releases
- All – Air
- Films – Final Check
There are a ton of silly mnemonics to help remember it—like “Begin With Review And Friend”—but what matters is doing the steps every single time, consistently and thoroughly. Here’s how I’ve made it part of my routine.
B – Buoyancy Compensator (BCD)
- Confirm the inflator hose is attached properly.
- Test both power inflate and oral inflate to make sure they work.
- Pull each dump valve to check that nothing is stuck open.
- Make sure the shoulder dump toggle isn’t trapped under a strap.
- Inspect the tank band and tug it—don’t just glance.
If diving with someone else’s gear, take time to learn how it works before the dive. In an emergency, you don’t want surprises.
W – Weights
- Show your buddy where your weights are located.
- Gently tug on each pocket to confirm they’re locked in.
- Ensure your buddy knows how to release your weights if needed.
This is about more than trim—quick removal can be life-saving in an emergency.
R – Releases
- Identify all release points: shoulders, chest strap, cummerbund, tank strap.
- Discuss your layout: octopus, pressure gauge, drysuit hose (if applicable).
- Make sure your buddy can remove your gear quickly in an emergency.
Think like a rescue diver: could you remove their kit fast under stress?
A – Air
- Fully open the tank valve—do not quarter-turn back.
- Breathe from both the primary and alternate second stages.
- Taste the air for contamination—report any foul odor or taste.
- Exhale first, then inhale to clear the reg.
- Watch your SPG while breathing:
- If the needle drops and stays down – valve is off.
- If the needle bounces – valve is partially open.
- If steady – you’re good to go.
F – Final Check
- Mask defogged and ready.
- Fins nearby and ready to don.
- Dive computer set and paired if air-integrated.
- Signaling devices like SMB, GPS, or whistle secured.
- Loose gear or hoses clipped and streamlined.
Do a final head-to-toe sweep and have your buddy double-check. Two sets of eyes catch more than one.
Final Thoughts: Make It a Ritual
When I first started diving, I thought safety checks were mostly for beginners. Now I realize the opposite is true. The more experienced I become—and the more gear I add to my kit—the more critical these checks become.
As I push toward SSI milestones like Specialty Diver and Advanced Open Water, I’m learning that being methodical and intentional is what defines a skilled diver.
So if you’re new like me, or building toward your next level: don’t skip the check. Make it automatic. Own your safety. And help your buddy own theirs too.
