The Complete Dive Briefing Guide
A good dive briefing isn't one conversation -- it's several short, purpose-specific ones, because a diver's real attention span for a briefing runs about five to eight minutes. Below is every briefing type you actually need -- predive, boat, night, and debrief -- what each one should cover, and a free checklist for each.
The core safety conversation, every dive
Vessel logistics, once per trip
Light discipline and separation in the dark
What happened, what to change next time
Predive briefing
The predive briefing is the core safety conversation -- the one that has to happen before every dive, every time, regardless of site or conditions.
- Water entry and exit method
- Hand signals and communication plan, including any non-standard signals specific to the site or trip
- Buddy procedures -- pairing, staying together, what to do if separated
- Emergency response basics -- what to do and who to signal if something goes wrong underwater
- Final gear check before entry
Boat briefing
Boat dives need an additional briefing layer that has nothing to do with what's underwater and everything to do with not falling off the boat or missing it on the way back. This happens once at the start of the trip, separate from the dive-specific briefing before each individual dive.
- What to bring topside and how to board safely
- Location of the head, safety gear, and communication equipment
- Emergency procedures specific to the vessel -- man overboard, engine failure, evacuation
- Charter-specific logistics -- surface interval length, re-boarding procedure, live-boat vs. anchored protocol
Night dive briefing
Night diving adds enough variables that it deserves its own briefing rather than an addendum to the standard one.
- Light signals and low-visibility communication -- standard hand signals don't work in the dark
- Buddy contact procedure -- closer proximity than daytime, more frequent visual/physical contact
- Separation protocol specific to darkness -- what to do, how long to search, when to surface
- Site-specific hazards that are harder to see at night
Post-dive debrief
The debrief is the briefing most operations skip, and it's arguably the one with the highest return on five minutes spent.
- What actually happened vs. what was planned -- depth, time, route, conditions
- Anything unexpected -- equipment issues, navigation problems, wildlife encounters, near-misses
- Lessons for the next dive at this site
- Post-dive care reminders -- hydration, sun exposure, no-fly time if relevant
Putting it together
For most trips, that's four short conversations instead of one long one: predive (every dive), boat (once per trip), night (when applicable), and debrief (after). If you're briefing a full team rather than a single buddy pair, a dedicated team briefing template organizes objective, roles, conditions, and emergency info in one place. For overhead-environment sites -- wrecks in particular -- briefings need an added layer of complexity.
And regardless of dive type, the briefing is also the moment to confirm your team's Emergency Action Plan is current -- not the moment to write one for the first time.
Frequently asked questions
Why split briefings into four separate conversations?
Attention. A diver's genuine focus during any single briefing tops out around five to eight minutes -- cram everything into one long briefing and most of it doesn't land. Shorter, situation-specific pieces actually stick.
Dive Backup organizes information entered by the dive team. It does not calculate whether a dive is safe or replace training, certification, professional judgment, dive computers, agency standards, or a live predive briefing.
Filling this in on paper works until conditions change or a diver drops out. Dive Backup turns it into a shared, reviewable plan your whole team can see, so nothing gets decided verbally and forgotten.
