4. Cressi Giotto Dive Computer
The Cressi Giotto dive computer is pretty much the big brother of the awesome Cressi Leonardo. At first glance the 2 dive computers are very similar looking but the Giotto has a few more advanced features that the Leonardo is lacking. Almost all the settings and options for nitrox or air diving are customizeable and the internal dive log is expanded to 70 hours or 60 different dives, complete with a dive profile that can be exported to your PC or Mac. The Giotto’s 3 button design makes navigating the menus super simple and the large screen is well laid out and readable. A bit more pricey than the Leonardo, but this dive computer is great as a high end entry level or mid range dive computer.

5. ScubaPro Mantis Diving Computer
Everyone knows ScubaPro makes some of the highest quality, most reliable scuba gear on the market these days. If you have a bit more cash to spare, the ScubaPro Mantis is worth looking into, it’s a great choice for an intermediate level dive computer and it looks amazingly slick. Starting with a more compact design, it has all the standard dive computer features, and you can purchase it with an optional heart rate monitor for an even more accurate decompression algorithm that takes exertion and stress into account.

6. Suunto Vyper Dive Computer
You might think this suunto looks a lot like the suunto zoop dive computer we recommended above. And you might be right, on the surface. This is the Zoop if Q got his hands on it and upgraded it for james bond. The Vyper dive computer has support for 3 different gas mixes, support for wireless air integration, an awesome digital compass, automatic safety stop timer etc, this is a high end dive computer that has almost all the features of the far more expensive Oceanic OCI at about half the price. Since the redesign of the vyper it has been flying off the shelves and for good reason. A great balance of performance and price for intermediate to advanced level scuba divers.

Probably the best dive computer money can buy, the Oceanic OCI is like the ferrari of wrist computers. While the price is pretty steep, this dive computer looks amazing and packs a TON of features into the compact casing. It features wireless air integration, which is a nice luxury, allowing you to check your remaining air supply with a single glance. It also has a great digital underwater compass so it is a good option for search and rescue divers, or anyone leading a group. The Oceanic OCI falls squarely into the high end scuba gear range and is for professional divers or those who simply want the best dive computer on the market. It falls lower on our list simply because it’s not a realistic option for many scuba divers. Premium level equipment right here.

The Newton is one of the newest dive computers from Cressi, released in late 2015, they took all the awesome things about the Leonardo and Giotto models and packed them into a more streamlined, feature rich package.

The Easiest Way To Avoid Decompression Sickness? Use A Dive Computer!
As we mentioned above, every diver fears getting decompression sickness after a dive. As you dive and descend to deeper depths, more and more nitrogen is absorbed into your bloodstream and body tissue. This is fine when it remains compressed at depth, but ascend too quickly and as the pressure levels change, those nitrogen bubbles start to expand. This can cause excruciating pain, and even death if one is unlucky enough. One of the best ways of having an accurate picture of what is going on inside your body is to simply use a dive computer on each and every dive.
Dive computers use complex algorithms to calculate the amount of dissolved nitrogen in your body by tracking your depth changes and length spent at each depth. All divers should have experience with the classic dive tables during their certification process but they can be confusing to use and putting yourself in the wrong pressure group by mistake is not something you want to do. A small mistake can cost you hours in a decompression chamber at several thousand dollars an hour, or far worse, cost you your life. Personally, the Diver World team just mitigates this risk by having each diver use their own personal dive computer on every dive, to have an accurate idea of their remaining dive time and to re-enforce safety! Scuba diving should be a relaxing sport and having one less variable to think about during your dive eases stress, and allows you to be more confident while exploring beautiful underwater environments.
