What is the BSAC buddy check procedure?
BSAC uses "SEABAG" buddy check: S = Suit and weight (check drysuit for leaks, weight securely attached, able to ditch), E = Equipment (BCD inflates/deflates, straps secure, SPG working), A = Air (tank on, breathing normally from regulator, octopus accessible), B = Buoyancy (BCD dump valves working, drysuit inflator/dump working), A = Assess (final visual check, nothing dangling, buddy agreement on dive plan), G = Gas (confirm gas analysis if nitrox, check pressure matches plan). BSAC emphasizes systematic approach over acronym memorization. Typically takes 3-5 minutes when done properly. UK diving adds drysuit check (seals intact, no holes) and cold water considerations (hood/gloves fitted, thermal protection adequate). Never skip buddy check due to time pressure or familiarity with equipment.
What is the PADI pre-dive safety check?
PADI uses "BWRAF" (Begin With Review And Friend): B = BCD (inflates and deflates, all dump valves working, secure attachment to tank), W = Weights (securely attached, able to ditch quickly, amount appropriate for dive), R = Releases (locate all releases: BCD clips, weight system, tank band, drysuit), A = Air (turn on, breathe from primary and octopus, check SPG reads full, sniff for contaminants), F = Final check (mask and fins ready, computer on, plan confirmed). Takes 2-4 minutes. UK modifications: add drysuit check (seals, inflator, dump), verify cold water regulator, confirm nitrox settings if applicable. BWRAF and SEABAG cover same elements with different mnemonics. Choose one system and use it religiously before every dive.
What additional checks do UK cold water divers need?
UK-specific pre-dive checks beyond standard protocols: Drysuit integrity (check all seals, test inflator and dump valves, confirm no holes or tears), thermal protection (hood fitted correctly, gloves donned, boots secure, undersuit appropriate for conditions), cold water regulator (environmentally sealed, recently serviced, breathes smoothly), visibility aids (torch working even for day dives, backup torch accessible, SMB attached and ready), and exposure plan (confirm maximum dive time based on cold not just NDL, agree on abort signals for cold distress). UK conditions make equipment failure more likely and consequences more severe. Rushed buddy checks are common cause of UK diving incidents. Budget 5 minutes minimum for cold water gear check.
How often should you do a buddy check?
Before every dive without exception: First dive of day (comprehensive SEABAG or BWRAF check, 3-5 minutes), second dive of day (full check even if same equipment, gear shifts between dives), after any equipment change (adding/removing weight, changing tanks, adjusting suit), after surface interval over 60 minutes (recheck everything), and any time you feel uncertain (better to recheck than skip). Many UK incidents involve experienced divers who skipped buddy checks on familiar equipment. Muscle memory makes checks fast (experienced buddies complete thorough check in 2 minutes). Complacency kills: UK diver fatality statistics show equipment problems (tank not turned on, weight not secured, BCD malfunction) feature in 30% of incidents. These are all prevented by proper buddy checks. Make it religious habit.
