Take A Deep Breath As We Review 4 Of The Best Nitrox Dive Computers



The use of nitrox in diving activities can greatly increase the number of possibilities for a diver who wants to explore deeper, further, longer.  

The type of dive computers which use nintrox make it possible to breathe gases other than oxygen, and monitor the pressures in real time.


What Is Nitrox?

Nitrox or enriched air nitrox, is a combination of gas and oxygen percentage higher than 21%.  

By using Equivalent Air Depth, divers are able to double diving time because of the ability to breath nitrogen at a lower rate by using a nitrox/oxygen mix.  

This allows an extended bottom time, and makes decompression smoother for the diver.  This is why the latest development of dive computers possess the ability to use nitrox in their programming systems.

Watch this video, to get a clearer idea of what we’re talking about in regards to enriched air nitrox…

Now that you have a better understanding of why a diver might want to use enriched air in their dives, let’s look at some of our favorite dive computer watches that can enhance and prolong our next diving excursion.

These watches are a bit on the pricy side, but hey, you get what you pay for, and these dive watches are quite sophisticated, and they make an essential addition to any serious diver’s equipment.

Suunto Cobra Dive Computer


This dive computer by Suunto is an air-integrated dive computer that is console-mounted, and also provides every-day users with a professional diving experience, leaving nothing to chance.
