What to look for when buying a dive computer
Some of the factors to consider when in the market for a dive computer include:
Data transfer
Many computers come with an integrated computer interface. This technology varies from manufacturer to manufacture. In some cases, a USB cable connects to the computer while other computers utilize an infrared interface. Some models come with dedicated software that connects to social media and eliminates the need for ‘logbooks.’
Gas
There are four main gas types used in scuba dive computers. Compressed air is made up of 21% oxygen and 79% nitrogen. Trimix is a mixture that contains nitrogen, oxygen and nitrogen.
Dive computers with Trimix are mostly used for deep dives greater than 50m. Nitrox mixture is the most widely used for exploration and is made up of 32% oxygen and 68% nitrogen. Some manufacturers are known to integrate helium into computer management, particularly where recreational diving is involved.
Console or wrist mounted
These are the two main mounting possibilities of scuba diving computers, each of which has its pros and cons. Console mounted computers are usually connected to a regulator hose and as such, losing them isn’t easy.
However, playback and control of different parameters can prove difficult if the diver’s hands are caught in the camera.
Wrist mounted dive computers, on the other hand, are available in a plethora of models and operation is hands-free making them ideal for daily use. They’re also great for beginners or those on a budget.
It’s easy to forget to bring along your wrist computer when going underwater due to its small size.
Air management
A scuba dive computer can provide indications on the pressure of the tank when underwater.
Such information is usually transmitted through a high-pressure hose and as such is only possible with console dive computers.
Battery life
Many scuba dive computers come with replaceable computers. Ensure that the battery of your scuba dive computer is easy to find. Some models can be charged via a USB cable.
Conclusion
Diving can be an amazing adventure but it’s important to make sure that you are safe every time you descend. A scuba dive computer can help you determine how long you should stay underwater and when you should come up.
If buying the right scuba dive computer sounds a little too complicated for you, this guide seeks to make that easier as you may have already realized.
Whether you are a new or experienced diver, this guide provides all the information that you need to make the right purchase.
