Best Beginner Dive Computers

If there’s one piece of equipment you need for a stress-free experience as a rookie diver, it’s a dive computer. This handy device shows you live information about depth, nitrogen levels and time you have left on an easy-to-read screen- so you worry less and have more fun.

For most entry level divers, a computer that notifies you when things start getting unsteady underwater is huge relief. Are you ascending way too fast? What direction are you heading in and how much time do you have left? It’s just convenient to have all of that necessary information right in front of you.

Though most dive shops have computers that you can rent out, it’s better to not rely on the dive shop and instead own your own dive computer.

Regular Features in Dive Computers:

  • Time passed
  • Safety-stop countdown reminder
  • Depth
  • Historic diving information
  • Emergency decompression
  • Ascent rate warnings that help you avoid ascending at a dangerous rate
  • Thermometers
  • In-built electronic compass
  • Adjustments for altitude diving

Besides the standard features, advanced dive computers come with a substantial learning curve.

You don’t need a whole lot of fancy features when you’re just starting out and already have a lot to learn. Just a few crucial ones and a sturdy display can suffice too. The amount of complicated diving computers with heavy user manuals is absurd.

There are endless options and brands that claim their dive computer beats the rest. Browsing through dozens of pages and reviews will only leave you with a strong case of analysis paralysis. Our carefully compiled list of best beginner dive computers will help you choose a good piece that’s worth the price tag and stands the test of time.

The best dive computers for beginners are:

  • Mares Puck Pro
  • Oceanic Geo 4.0
  • Cressi Leonardo
  • Aqualung i300C
  • Suunto Zoop Novo
