Distributions of maximum dive depths.Table 8 shows dive computer use. For PDE, 90% of all divers used computers. All PDEdivers wore a computer to record their depth-time profiles even if they did not dive according tothe computer. For injuries, half the air divers used computers. Computer use was more commonfor nitrox fatalities than for air fatalities.Table 8.
