A dive computer is one particular of the most beneficial accessories accessible for SCUBA divers, and it is a single of the pieces of gear that can determine a severe recreational diver from a casual 1. Couple of divers who have ever used a dive computer relish the prospect of going back to diving with out 1.
Dive computers usually come in the type of an more than-sized wrist watch, but some are developed to be practical replacements for the stress gauge on a regulator. The primary objective of a dive personal computer is to replace decompression tables, employing its on-board timer and stress gauge to automatically calculate the exact same info, but with considerably greater accuracy than would ever be possible with mere pen, paper, and a dive table.
The most basic versions will constantly show the following data: current depth maximum depth attained on the current dive the current “no cease time,” or time until a decompression quit is needed total dive time and the actual nearby time. Most also have on-board thermometers and can study out temperature, a handy bit of info when diving across thermoclines. These that are attached to regulators will also read the pressure remaining in the air cylinder, just as the old analog gauge did. Some will also supply data on essential decompression quit time, as well as sounding a warning for ascents that are as well speedy.
Combined, this accurate and automatically tabulated details is handy for the recreational diver, especially on long, 3 dive days. This is typically the only time where decompression and spending enough time on the surface will turn out to be an situation for a recreational diver following suitable procedure. Dive computer systems are also of potentially vital value for the technical diver, who routinely have to program complex, multi-staged dive with decompression stops. A error in the decompression math can outcome in a case of the bends, so it is useful to have a laptop double-checking those calculations along on the trip.
These devices are so useful that most serious recreation divers do not ask no matter whether to get a single, but when. Some decide on to wait until right after assembling the fundamental minimal kit of locate, mask, wetsuit, and regulator. Other people buy it before, assuming they will often be able to rent simple gear, but not a dive computer.
Rates can differ enormously, depending on good quality and the quantity of functions. Wristwatch versions are priced amongst $ 300 and $ 1300, but a very good dive laptop will generally be at least $ 450.
