Dive Computers

Dive Computers take the stress out of scuba diving. Their ability to measure bottom time, adjusted bottom, depth and time, have helped scuba diving to become the safe sport it is today. Diving is one of the safest activities to undertake as a hobby, the safety features available to divers these days is amazing.

Buying Dive Computers

Dive computers not only sound expensive and they can be very expensive, it all depends what you actually need the computer to do for you. If you are going to the bottom of the sea on a record breaking 300 metre dives, then I suggest you consider the market very careful indeed; maybe buying several computers of the highest grade.

If however, you will be using your new dive computer for general scuba diving, in friendly environs. Such as the warm waters of Thailand no deeper than 30 metres or so, then you do not have to go and spend thousands upon thousands of your hard earned cash to feel safe.

There are nowadays some great deals out there for inexpensive scuba diving computers. I would recommend popping down to your local scuba diving equipment retailer and check out what is on offer. Most of the main scuba diving brands have a decent line in dive computers, so you will recognise their names.

Where to Wear your Computer

The wrist dive computer is very popular. There are several ways to wear a computer and on the wrist is possibly the diver’s favourite, but not every diver prefers this way. Wrist mounted computers look like large watches, almost like a dinner plate, they are a real give away to other divers that there is another diver in the area.

However, unlike dive watches, people tend not to buy a dive computer unless they are actual scuba divers, though some people will wear their dive computer as a watch in between dive trips. The choice between wrist mounted and having the computer mounted on your dive console is a personal choice.

Some dive computers give the diver a choice; the same model can either be worn on the wrist or on a console. Either way, when purchasing a dive computer it is best to make sure you can see all the information on the screen. This is not usually a problem, due to magnifying effects that scuba diving masks have during underwater activities.

Some dive computers, like I have said, are very similar to watches in their shape and size. On the market there are many shapes and sizes to choose from, some computers are rectangular in shape giving the diver maximum screen vision. One of our Favorites are the new Aqualung wrist computers.

One downside to having a watch like dive computer is that divers tend to wear them more often than not, even when they are not diving, any slight dampness can set the computer into ‘Dive Mode’ and this can waste your battery life quite quickly. Although if the idea is to impress your friends that you are a scuba diver, then what’s the harm; it’s your money

A console dive computer is attached to the SPG console normally, which is part of the scuba regulator. This style of computer is generally larger than the wrist mounted one, and is easily detachable. Dive computers typically come with a pressure gauge, unlike the wrist mounted option.

This style of wearing your computer means that you will possibly have the computer attached via a high pressure hose to your 1st stage. This type of computer is air integrated which means that precise air readings are given as well as all the other info by the computer.

These days scuba divers, particularly on Thailand liveaboard dive trips (the diver goes onboard a dive boat for several days even a week or more), will have noticed that nitrox has become very popular.

So I would definitely recommend that even if right now you are not Nitrox certified, that dive computer you buy make it a Nitrox compatible computer, forward thinking is what separates divers form the rest of the pack.

If money is no object and you do enough diving throughout the year to justify such an investment, then maybe have a look at the hose-less computer set. These computers use a transmitter from the 1st stage to the computer which transmits all the info to your main computer on the wrist or console, these are top of the range and cost a pretty penny, especially the ones made form titanium.
