Scuba Diving – Why Upgrade to a Dive Computer?

Do you often engage in repetitive dives and on minimal surface intervals at that? If you do, the use of dive or decompression tables to determine safety stops and no decompression limits (NDL) can be quite restrictive to your scuba diving agenda in terms of bottom times and against any eventuality that could get you off-track a presumed square dive.

Dive tables can only provide a static picture of decompression limits that has been configured for a particular dive profile, dive time and depth. Square dives also operate with the assumption that the diver descends to the predetermined bottom immediately and lingers at that depth for a set period of time before ascending to the surface. In fact, different dive tables are utilized to match certain dive profiles where some configurations take into account level of diver training and the physical stamina of the scuba diver.

The functional limitations of decompression tables now find resolve in the use of a dive computer that has become a popular scuba equipment or gadget nowadays; not only among professional divers but also with the hobbyists of recreational scuba diving. While theoretical times are still calculated, dive computers are programmed to continuously monitor dive time and depth. Thus, allowing the scuba equipment to make ongoing calculations on the uptake of inert gases in the body and determine a safe ascent rate based on actual time and depth reached for the dive. The actual re-computations (of no stop times) performed by the dive computer can help extend bottom times while using the same volume of gas taken up in the NDL computations of a square dive.

Dive computers will prove to be very useful in the uptake of decompression parameters for repetitive dives. This is based on the fact that the device operates via a model determined to theoretically track nitrogen levels in all tissues of the body; thus, reckoning less conservative NDL readings. The model used for decompression tables, on the other hand, reckon NDL from a single bodily tissue purported to discharge Nitrogen at the slowest off gas rate, to restrict repetitive dives particularly below recreational depths.

But that’s not all dive computers are programmed to compute and display on its panels. There is also a convenience factor that contributes to the popularity of this scuba equipment []. For one, the dive computer is the convergence of various scuba equipment that have been used to separately convey vital information to the diver, such as the pressure gauge and watch. Now you won’t have to bear the drag of those scuba equipment during your dive since the display of pertinent information have been integrated with the functions of the dive computer. Moreover, the dive computer can provide you with actual data on water temperature and diving cylinder pressure that will only serve to extend your safety margin as you descend to your decompression limits or pursue repetitive dives within the day.
