A Suunto Dive Computer
Dive computers will tell you the depth, time, and your No-Decompression Limits.

Hand to heart, I’m a big fan of the Suunto Zoop dive computer. It is easily one of the best dive computers for beginners that is currently on the market. But I may be biased, as this is what I used when I first started scuba diving. As a dive instructor, it is also the dive computer that I use for my diving students. But why is it so good for beginners, and what other dive computers can compare when competing for the best dive computer for beginners?

What to Look for in a Dive Computer

Here is a list of features to look for when choosing the best dive computer for beginners.

  • The dive computer will be set to the standard AIR mode, which is 21% oxygen. All dive computers now have the NITROX mode too, which allows you to change the oxygen percentage. GUAGE mode is handy when using the device as a depth gauge only. FREE diving mode allows you to log and save your freedives.

A good feature to look for when choosing the best dive computer for beginners is whether you can change the battery yourself. Some dive computers only require a simple tool to open the back and replace the battery. However, other dive computers will require you to send it off to their authorized service center to change the battery. This can be costly and time-consuming. When replacing your own battery, follow the instructions from the dive computer manual and check that the o-ring rubber is properly sealed.


Dive computers can be slightly overwhelming to a beginner diver. There are a lot of numbers on the screen, letters, and potential graphs. This can make reading a dive computer confusing. You should opt for a dive computer that is easy to read with a large interface. This is especially important if diving in low visibility or if your eye-sight struggles with reading.


Besides knowing your depth, one of the most important features on a dive computer is the No-Decompression Limit (NDL) or No-Stop time. You should read your dive computer manual to ensure you understand and know how to read the depth and the NDL.
