The Dive Computer, an Essential Item You Should Ow
The recreational dive computer has allowed divers to extend their diving as well as giving a better means to prevent DCI. The development and publishing of the recreational dive tables was one of the first steps that increased the safety of divers. These tables were a modification of the tables that the U.S. Navy had developed for their divers. For the recreational diver, the Navy tables had some fundamental even fatal flaws. Navy divers normally worked at one depth, they descend, do the job and return to the surface. The No-Decompression Limits (NDL) were easy to follow for them. Recreational diver are more likely to spend time at different depths while diving. So following the NDL left the potential of unused diving time. On the other side of the coin, the Navy tables accepted a higher degree of risk than a recreational diver could be expected to accept. Navy divers would follow the same tables in times of war, were mission requirements were higher. The Navy divers also h...
