Secti<strong>on</strong> 2 - <strong>Project</strong> <strong>Dive</strong> Explorati<strong>on</strong> (PDE)2.6 <strong>Dive</strong> PlanningTable 2.6-1 <strong>and</strong> Figure 2.6-1 illustrates the use of dive planningmethods. Most divers in our sample used dive computers to plantheir dives <strong>and</strong> determine the dive time <strong>and</strong> the ascent. In 2003,<strong>on</strong>ly 1 percent reported relying completely <strong>on</strong> others for theirdecompressi<strong>on</strong> planning. This is much less than in previous years.<strong>Dive</strong>rs reported relying <strong>on</strong> dive tables in <strong>on</strong>ly 2 percent of thedives.Interestingly, in the Beach <strong>and</strong> Day Boat subgroup, relying <strong>on</strong>another pers<strong>on</strong> was highest in comparis<strong>on</strong> to other subgroups(Table 2.6-1). The Beach <strong>and</strong> Day Boat subgroup varies most withinthe subgroups in terms of diver experience <strong>and</strong> probably thelevel of organizati<strong>on</strong> of the diving. Nearly 10 percent of recreati<strong>on</strong>aldive professi<strong>on</strong>als (dive guides) relied <strong>on</strong> dive tables.Table 2.6-1<strong>Dive</strong> planningmethod am<strong>on</strong>gfour PDEsubgroups.Subgroup<strong>Dive</strong> Plan Cold-Water Recreati<strong>on</strong>alLiveaboard Beach <strong>and</strong> Wreck <strong>Dive</strong>Day Boat <strong>Diving</strong> Professi<strong>on</strong>als<strong>Dive</strong> Computer 81.5 82.4 97.9 88.1Table 0.3 4.4 2.1 9.5Another <strong>Dive</strong>r 0.2 1.8 0.0 0.0Not <str<strong>on</strong>g>Report</str<strong>on</strong>g>ed 18.0 11.5 0.0 2.4Figure 2.6-1Use of diveplanning <strong>and</strong>decompressi<strong>on</strong>planning by dive.36DAN’s <str<strong>on</strong>g>Report</str<strong>on</strong>g> <strong>on</strong> Decompressi<strong>on</strong> <strong>Illness</strong>, <strong>Diving</strong> <strong>Fatalities</strong> <strong>and</strong> <strong>Project</strong> <strong>Dive</strong> Explorati<strong>on</strong>: 2005 Editi<strong>on</strong>
