The use of nitrox in diving activities can greatly increase the number of possibilities for a diver who wants to broaden their scope. These types of dive computers 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. With multiple technological advancements, it has the ability to provide cylinder pressure and time remaining during dives. It is also equipped with three-step altitude adjustments. The compass included is able to surpass regular installed compasses by having an exceptional tilt potential that is larger than the average diving compass.
Suunto Cobra Dive Computer Features:
- Contains three dive modes: air, nitrox, and gauge that makes adapting to different diving situations possible.
- The Suunto Cobra is naturally programmed with the Suunto RGBM Algorithm which provides a detailed and on point description of activity in the body, and allows continuous decompression.
- One Nitrox mix
- Programmed with an integrated digital compass for effective dive planning and reduces unnecessary excess swimming.
- Hose air-integration provides accurate remaining air supply to device.
- Maximum depth: 80 meters
- Equipped with recommended and mandatory safety stops when approaching a no-decompression limit.
- State of the art, high quality compass is able to provide details on an easy to read large side-reading window.
- User replaceable battery
- Does not have the ability to retain data.
Take a look at this video to get even better acquainted with the Suunto Cobra, which provides useful lessons on its operation.

- Wireless Four Nitrox mixes
- The OCi can reach a maximum depth of 150m, which provides perfect diving availability for the recreational diver.
- A user replaceable battery prevents unnecessary trips to a location to get it professionally exchanged.
- This computer is programmed with the ability to retain data during dives.
Watch this video on the Oceanic OCi dive computer to brush up and learn the basics.
While many of these dive computers have multiple capabilities in common, such as an integrated compass and data retention, the main options that set them apart are the price differences, nitrox percentages available, and the amount of dive modes for each computer. It is always important to explore your options when purchasing such complex and sophisticated technology, especially when your safety is at stake. Luckily, the freedom that you will get as a diver as a result of doing a bit of reading and watching is well worth it! See you out there!
