About the ScubaProof Trust Score
Safety: Emergency O₂ readiness, instructor-to-diver ratios, dive briefing quality, and proximity to a hyperbaric chamber. Safety carries the highest weight because DAN incident research identifies supervision and emergency response as the leading factors in preventable diving fatalities.
Staff: Active agency certifications (PADI, SSI, TDI, CMAS), language coverage, and instructor conduct described across reviewer reports.
Gear: Equipment condition, servicing transparency, nitrox availability, and rental quality reported by divers.
Red flags add automatic penalties: −0.8 pts per critical issue (equipment failure, skipped safety protocols), −0.3 pts per warning. Reviews are time-weighted — a report from three years ago carries 20% of the weight of a current one. No dive center can pay to improve its score.
