Every dive you do with Air or Nitrox is fully processed by this reliable computer – calculation for safe decompression, dive data history which can also be stored. It’s easy to plan your dive with its accurate and automatic calculations and you can fully reset the device after each use (good if you are in the rental business). See and hear your alarm clearly underwater – vital for keeping you safe and avoiding diving distress. Your Cressi Giotto comes with 70 hours of log time to keep track of all your dives.

This dive computer is reasonably priced if you are on a budget and the recommendation is to go with this as a starter unit until you are ready to upgrade.

The Suunto Zoop also comes with visible alarms that help to keep you alert while you dive.
The LCD displays allow clear reading underwater and crucial information like the remaining no-decompression time and the rate of ascent are shown using colored graphs. Freedivers can also use the Suunto by changing the setting from Scuba. Keep track of all your dives with the built-in planner and choose the option of detailed log graphs and analysis of dive data.

The display is segmented into a matrix and is backlit – for easy reading. The information on screen is larger and clearer. Four buttons are all it takes to control this scuba dive computer. Once under water, you can see how well the Suunto Zoop Novo works for you. You might find it a little difficult to use it in low light and during night dives because of its weak backlight.
The alarms work well however and you won’t have trouble knowing when to ascend and to take the safety stops. You can recharge the battery for longer use so no need to replace it. The icon showing whether it’s safe to fly is not so easy to see without glasses, at least according to one user.

Set up your Nitrox percent or Air – you also have the option to go free diving instead of scuba – it’s that versatile. Did I mention that the D4i is great for those long diving trips?
You can depend on its reliability when you choose to take an extended diving vacation. It is also a Reduced Gradient Bubble Model that is a popular choice among divers.

Oceanic has provided the OCi Wrist Wireless Air-Integrated Dive Computer for the professional and recreational diver. If you are into innovative technology, check out the OCi that PADI Master Diving Instructors are also happy with. The fact that this unit comes with a complete warranty from the manufacturer shows how confident the makers are that you will be totally satisfied.
Does this oceanic dive computer measure up? Let’s see – Automatic altitude adjustment capabilities (Check!), user customized digital compass and alarms (Check!), flexibility in sea or river / lake conditions (Check!), nitrogen calculations in freedives (Check!). This seems pretty good for a computer that also doubles as an ordinary wrist watch. Some users are a little disappointed with the unreliable battery, which requires frequent recharging. Communication between the computer and transmitter is also sometimes weak. If you don’t mind these glitches, you can go ahead with the Oceanic OCi and enjoy its main features.
- Complete Manufacturer’s Warranty provided

- Can be used for free dives

Talk about a Reduced Gradient Bubble Model Dive Computer that can work at a depth of 492 feet, and you are talking about the Mares Puck Wrist Dive Computer. It’s a fully functional Nitrox / Air dive computer that does not compromise on features. You have the ability to set your Nitrox mix between 21 and 50% as well as set your safety details easily.
This Puck is appropriate for recreational divers although pros can use it too. Displayed information is so easy to read underwater and navigation is a snap with its single button – simply scroll through! Logging more hours of dive time is possible with its extended memory. Track your dates, dive times, rate of ascent and temperature, and many more details in this powerful logbook.
Underwater safety is ensured with alarms you can actually hear, and deep stops are a must for safe ascents. Ignore the countdown timer to your peril – You won’t be allowed to miss the safety depth as the timer will stop and you must return to the safe depth to start again. If however, technical diving is your preference, consider a dive computer with at least two buttons or more.

See your dive information on a sharp display. In fact, reading the information and dive graphs is ridiculously simple, thanks to a large display screen.
You can easily set your Nitrox mix anywhere between 21 to 99% or choose to use only Air. Seriously though, you won’t lose your way underwater with the tilt correcting, embedded compass, which is quite accurate. The stopwatch is precise, which is great for managing your dive time.
Automatically keep track of all your dives with the Mares Matrix 35-hour logbook, and save hours trying to do it yourself. Your battery can be charged again and again – meaning no need to change your batteries unless you want to.

Its huge display allows you to see everything clearly, even with poor eyesight! Expect loads of features from your handy Mares Puck Pro – accurate depth recording, 35 hours of dive memory for logs, bottom timer after four feet, powerful planner that tells how long to dive without decompression, bar graph display of your descent, alarm if you go too far too fast (exceeding 30 ft. per minute), warning beeps for deep stopping during ascent, it even tells you when it’s safe to fly commercially over 30,000 ft.
Although it’s easy to use, it’s a good idea to take time to learn how to properly use your wrist dive computer. If you snorkel between dives, prepare for the annoyance of your re-submerging being treated as a new dive! Also check your battery compartment and dust caps for any defects – read your seller’s return policy before ordering or purchase from local dive shops and closely examine dust caps, battery compartment and areas that may pose problems later.

You might want to consider the Shearwater Research Petrel Dive Computer. If you are a recreational diver, this computer is also right for you. What makes this a wise choice is the much smaller and slimmer design for both diving and everyday wear. You can still enjoy the big display which is an outstanding feature of the Shearwater scuba dive computer. See information in full color, and at high resolution.
A welcome change to this computer is the ability you have to replace the batteries with any AA type or even the ones you can recharge. Remember that if you use any inferior battery, your dive time will fall. Although the straps are elastic and easy to adjust under water, they along with the buckles, are a little annoying to deal with. You may have to trim the strap for a better fit, or find an alternative material like Velcro to keep your computer secure on your wrist.

Dive Computer Maintenance Tips
The main maintenance that your computer will need is the periodic change of the battery . Some models allow you to change it for yourself, while others require you to take it to the technical service.
Personally, I prefer computers that allow you to change the battery at home, since you avoid having to send it to the technical service, as long as it implies and, in addition, you usually save money.
In addition, whether it is to change the battery or any other problem that could arise with the computer (no matter how much you buy a very good brand, it is still an electronic device, so something could fail at some point), it is important That the brand has a good technical service .
Large brands such as Mares, Suunto or Cressi usually have a fast and efficient service . You sure do not want to stay 2 months without a computer in the middle of the diving season!
On the other hand, after each dive, remember to clean your computer (like the rest of the equipment) with fresh water to remove salt and possible sand scraps. Do not keep your computer wet: let it air dry, but avoid direct sunlight.
If you have the possibility before you finish deciding, when you go diving ask your diving partners if they are happy with their computers .
Although many will say yes and try to convince you that the computer they carry is the best on the market, there are always some who will give you useful information, such as the facilities to change the battery, if you miss something, anecdotes of other models / Computer brands that they had before and why changed them, etc.
It can also be helpful to talk to the guides , especially if they are instructors with years of experience, since they have often tried many different models and brands, so they can give you a broader and more consistent view.
How to make the final decision
In summary, when choosing the computer , I recommend that you keep in mind the following points:
1. Decide what your budget is : this will help narrow the possibilities.
2. Think about the use you are going to give : Will it be a few dives per year or do you plan to dedicate yourself professionally to diving? Would you like to try other types of scuba, like apnea or nitrox? Be realistic and buy a computer that meets your needs, but you do not need to take the best of the market. However, you do not want to go for the cheaper option. You do not want a computer that gets you thrown after 50 dives, or that you are short in the medium term.
3. Choose a computer that is easy for you to manage : include all the relevant parameters on the main screen during the dive and make it easy for you to read and interpret .
