Best diving computer reviews

​A dive computer, a personnel decompression computer, a decompression meter, or a mini watch/device, whatever you like to call it, this device is widely used by divers to measure time and depth and perform calculations for allowed time at depth, decompression times, and ascent rates. Dive computers increase safety and extend dive times.

Historically, dive computers were first introduced by two Italians - De Sanctis and Alinari in the year 1959.

A dive computer generally works on a real-time ambient pressure input mechanism to measure depth. Many dive computers provide additional information to the divers such as water temperature. You might find it hard to believe, but these mini dive computers are capable of re-calculating data based on the continuous changing positions of the divers.

These computers have numerous applications and are also used to calculate decompression schedules in various scientific and military operations. Not only this, dive computers also find a range of commercial usages as well. As a matter of fact, various innovative dive computers are also capable of calculating decompression for breathing gases like nitrox, oxygen, trimix, and heliox.

Keeping their growing popularity in mind, a lot of variants of dive computers are introduced in the market today. From wrist mounted computers to the ones which can be fitted to a console with the submersible pressure gauze – there is a range of choices you can choose from.

If you are new to the diving world, or have not used a dive computer before, you might now know how to use a diving computer. Well, this is what the next section is all about.

​How to Use a Dive Computer

​As stated, you might find dive computers a bit complex. However, they are very easy to operate. You just need to ensure that all the required parameters are carefully set before you dive, and you are good to go. Here is a quick guide to help you understand how these mini dive computers can be used effectively:

​Algorithm setting

Algorithm settings could be different for different underwater computers. Thus, it is essential that you make yourself familiar with your device before you dive in the water. Various dive computers even allow you to customize the algorithm settings, and if your device allows you to do so, consider yourself as lucky.

You can choose between a conservative algorithm and a liberal algorithm. This function particularly helps you out when you need to match your computer’s calculations with your dive buddy’s computer.

​Conservative factor

​This factor needs to be essentially set each time you are diving. To set this properly, it is highly recommended to consider the non-deco countdown basics.

​Air/Nitrox setting

The air and nitrox settings are present in most of the scuba diving computers. As a matter of fact, you can dive on air or 36 percent nitrox, or 32 percent nitrox. The best scuba dive computers available today have nitrox as their default settings that get activated immediately after 24 hours.

Thus, it is highly recommended to check your nitrox settings before going into waters to make sure that your cylinder and computer are on the same page.

​Alarms

Make sure that you make your audio or visual alarms a central part of your diving plan and especially if you are diving to an area with beautiful corals and fishes that might distract you easily.

​Stop parameters

It is highly recommended to program your own safety stop parameter. You can program it to the standard 3-5 minutes for a depth of 15-20 feet.

​Deep stop parameter

​There is still an ongoing debate if the deep stop is actually beneficial or not. While some experts support the idea, others are against it. Well, it is your choice. However, you can always to choose disable it as needed.

What Features to Look Out For?

​Thankfully, a digital dive watch does not look complex today. Instead, they look more advanced and high-end when worn as a wrist watch. So, what essential features should you look for? Here are a few of them:

Display screen

It goes without saying that a display screen is important as this is where you are going to get all the information. Make sure that you pay attention to its size and lettering, and also check if it is equipped with LED backlight.

​Dot matrix

​You can go for a dive computer having a full dot matrix that uses small dots to make up a number or a character or the one that uses segments of lines for creating characters. Some watches have a combination of both.

​OLED

​In an OLED screen, the digits light up themselves and give you clear information. Sometimes they also make use of different colors so that you may easily differentiate between the information.

​Colorful LCD

​You may also choose to opt for a colorful LCD display so as to differentiate between data easily without straining your eyes.

​Memory

​It is essential that your dive computer comes with an appreciable memory so that you can review your dive logs on the go. Generally, most dive computers are easily capable of storing a dive history of around 15-20 days.

​Alarms and battery

​If you are a new entrant to the world of diving, it is highly recommended to go for a dive computer with an alarm feature so that it can alert you at maximum dive limits. The best alarms are both visual and audible, and are easily noticed in the water.

Also, make sure that your device is powered up by user-changeable batteries such that you don’t have to visit the technician every time the batteries run out of charge.

​Navigation

​Again, this is an important parameter you must pay attention to. Double check if your chosen dive computer is easy to navigate and allows you to operate flawlessly even when you are diving under water. You might also like to choose a dive computer with compass or GPS.

​Size

​Remember that you’ll have to wear this dive computer in the water for hours at a time. Make sure the drag won’t be enough to discomfort you, and make sure the weight and size are comfortable.
