You, therefore, need the best dive computer for beginners. This task presents some kind of challenge, more so when there are lots of them and you might not know what features to consider. This buying guide would be a welcome relief for you.

How to Choose the Best Dive Computer for Beginners?

  • Have Your Level of Expertise in Mind

As a beginner, the best dive computer is one that you can comfortably use its provided features. There are certain features you might not use until you reach an advanced level. Paying for one with such would be like drying your hay while the sun shines. You can also think of the future and purchase one with features for a mid-range diver.

  • How Much Are You Willing to Pay?

First of all, if you can’t afford it, there is no point trying to buy it. Prioritize your budget as it helps you narrow down the available options. This will help in making for an easier choosing process. At the same time, do not have a fixed budget as it is an investment for the long run. If your budget is no issue, then feel free to choose from the available ranges.

What Are the Advantages of the Best Dive Computer for Beginners?

A dive computer accrues a beginner a lot of benefits. Here are some of the reasons to get one:

  • It guides you through a dive, ensuring your safety in the process. These computers allow a diver to configure their dives, based on preferences. As you dive, you get reliable feedback for confidence.
  • You are freed from the complex calculations. In turn, all you have to do is concentrate on your sight-seeing as you enjoy your underwater experience.
  • Provides a beginner with an easier way of recording and sharing adventures than when diving without one. With their logbook memories, you don’t need paper logbooks.

Things to look for in the Best Dive Computer for Beginners

  • Ease of Use

A dive computer that would take you minutes to decipher the information provided is not worth a penny from you. Look for one with basic features that you can use and figure out yourself.

Buttons need to be large enough to be pressed with gloves on. I recommend getting acquainted with how the system works before taking a dip into the water.

  • Readability

It doesn’t make sense to buy a product that you cannot read its digits with your mask on, does it? If you can find one with a multi-color display, the better for you. However, it doesn’t have to be so. Having a dark color but on a high contrast background eases readability under water.

  • Nitrox Compatibility

You may not need it at first, but you will need to nitrox in the near future. Choosing a dive computer that is nitrox integrated saves you on making the upgrade when you decide to use it. Alternating between nitrox and air is flexibility that every diver needs.

  • Digital Compass

Knowing where you are headed in a dive is very important. When you have a dive computer, there is no point of having an analog compass for the same. Having the digital compass in your gear conserves space.

  • Mounting

The mounting aspect of the computer is essential during a dive. Most of the options available are worn on the wrist, while other options allow you to attach them on your suit.

Either of them has its own advantages. So you can choose whether you prefer a simple wrist twist when taking a reading, or having a hands’ free operation when adding weights.

  • Gauges

There are certain gauges that you can live without when under water. These include the amount of remaining air and time spent underwater. Some computers have additional gauges such as decompression time and alert to inform you when you are descending too fast.

  • Audible Safety Alarms

The computer you choose should warn you when you are putting yourself at risk. You could be descending too fast or have little air remaining. The warning systems should be audible enough so that you can react accordingly.

What's the best way to use the Best Dive Computer for Beginners?

Before you use a dive computer, check to ensure that it fits well on your wrist. Having a sophisticated computer which has a terrible fit does not work well for you. Consider your wrist sizes and the material which it is made from before diving into your hobby.

Controversy Surrounding the Best Dive Computer for Beginners

In the past, there has been folklore surrounding the use of nitrogen during dives. Nitrox diving was considered some kind of a dangerous activity. Nitrogen gas was thought to be a harmful gas that could potentially lead to the death of divers.

Contrary to this belief, nitrogen is a safe gas unlike how it was portrayed in magazines before. Divers all over the world are safely using the gas for diving.

Prerequisites to using the Best Dive Computer for Beginners

  • Ensure you are physically fit to scuba dive in the first place. The high pressure your body experiences when underwater demands that you be of impeccable health and that your body functions as it should. The medical questionnaire you fill becomes essential.
  • You should be of the right age to dive. Essentially, you need to be at least 8 years and above to use your dive computer. No upper age limit exists at the moment.
  • Be well versed with the functionality of your dive computer. Don’t wait to figure things out in the course of a dive.
