While most Dive Computers are a great alternative to standard Dive Tables, some models just can’t beat the old school way of doing things. It is important then to know the basic fundamentals of a Diving Computer to know which one would be most favorable for you. As with everything that concerns diving, it’s important to always have a back up just in case the need arises. This article will focus on the most common kinds of dive computers as well as a general information overview.
What it Does
To track your diving profile is the main basic purpose of a dive computer. Directly estimating any decompression stops that maybe necessary, the computer calculates your remaining No-Decompression Time and logs all the information for your later reference. How long it has been since you’ve surfaced the Diving Computer also records how long your dive was and how deep you had dived.
The Classic Model
Particularly important to know where each one is coming from many models of Diving Computers have classical analog, depth gauge and two separate gauge indicators, namely the tank pressure and depth indicator to see how long one can stay down on a dive. This model requires the diver to manually compute the information.
The Standard Model
The most popular standard model of Dive Computers is also classified as basic, has the same analog tank pressure gauge like the classical model, but has been replaced with a digital depth gauge indicator. As well as how deep you are in (depth indicator), the LCD screen reads out your downtime limit. With no-decompression times for you, it also computes any nitrogen loading and No-decompression times.
These models for nitrox diving calculates the extra amount of oxygen that is in the tank you’re breathing from. A computer module (for some models) is able to calculate the nitrox tables and comes with a pressure gauge.
Designs and Layouts
In different layouts and designs many models are highly relevant with an extra module attachment spot for compasses. Requiring a back up external standard pressure gauge, there are wristwatch-style dive computers that calculate and display all your diving needs as well as being able to function like a normal watch by telling you the time. Convenient for easier reading than the wristwatch design there are also wrist mounted dive computers specific for diving which tend to be bigger. There are even models that allow you to download all the data for later study and connection to your home PC.
When it comes to diving, a parting advice for the beginner, it is important to know and choose a conservative and reliable model. A diver begins to see which details are the most important to have on display but this will come with experience which is accumulated over time. A Dive Computer should always come first that is convenient as well as being suited to your diving comfort and safety needs.
