What is a Dive Computer?

A dive computer is one of the most vital pieces of scuba diving equipment that any diver needs to invest in. A scuba diving computer tracks your depth and time on each dive. It also displays real-time information and ensures that you don’t stay down for longer than is safe as well as making you aware of your depth so you don’t go beyond deeper the limits in your dive plan. And of course, if you are diving over multiple days having your own dive computer tracking will ensure that all this information will be based on any previous days diving you have been doing.

Dive computers are essentially used to determine how long you can stay under the water at a certain depth. Therefore, you can monitor your decompression stops and ascent rates both for your first dive and subsequent dives. The best integrated dive computers for beginners come with screens that display large digits, providing easy-to-read information.

A standard dive computer for beginners will incorporate the following features:

  • Time: the amount of time you have been diving for
  • No Stop Limits: notifies when to make decompression stops
  • Dive Depth: how deep you are diving below the surface
  • Ascent Rate: how quickly you are returning to the surface
  • Previous Dive Info: allows you to monitor your diving activities
  • Enriched Air Compatible: for extending your ‘no stop limit’
  • No-Decompression Limit: the maximum amount of time you can spend at a certain depth
  • Emergency Decompression: signals when you ascent incorrectly
  • Low Battery Warning: tells you that the battery is about to die

Factors To Consider When looking for Best Dive Computer for Beginners

There are a lot of considerations that go into the play when deciding between these top dive computers. If you are not aware of what to look for in a dive computer, this short guide will help give you some clarity.

The following are some factors that you need to consider before you choose your dive computer. This will help you in making an informed decision.

#1 Design and Build Quality

First and foremost, you need to review the design and build quality of the computer. Because you will be using it underwater, it needs to be of top quality.

When it comes to design, you should be able to read the information displayed on the screen. Also, there should be ample light to make it easy on your eyes.

Most importantly, the buttons should be minimal – 1 or 2 maximum. More buttons mean more confusion.

Finally, the computer should be able to bear the pressure and should be water-resistant at least up to 100 meters.

#2 Features

The minimum features that a beginner dive computer should have include:

  • Overall Dive TIme
  • No Stop Time
  • Maximum Depth
  • Current Depth
  • Time

Make sure that your dive computer displays this information all the time.

#3 Alarms

The most underrated feature that every dive computer should have is ‘alarms.’ The computer should let you know with an alarm when stuff happens.

These are some basic yet most important features that an entry level dive computer should have. Look for these when buying your first computer.
