Cressi leonardo Dive computer Review

We've done all the work for you and found the best prices on the Cressi Leonardo:

Our recommendations:

I picked up this dive computer to give to students and dive tourists. For my students it is easier to keep track of their dive times, ascent rates, and helps them understand how their time effects how long they can stay underwater with multi-level diving. The ability to reset the computer was the deciding factor to buy this for my classes. The oversized case is a little annoying, but not terrible.

Suunto ZOOP NOVO Dive computer Review

We've done all the work for you and found the best prices on the Suunto Zoop Novo:

Our recommendations:

The Zoop Novo was a great purchase for my wife; she hasn’t been diving for long, so I wanted an easy to read computer to help her monitor her no dc time and ascent rate. The only down sides are that it is not comfortable for her to wear during surface intervals, and the lack of integrated air means she has to monitor two separate gauges.

Pro's and Con's of the Suunto Zoop Novo dive computer:

  • Best for: Entry Level 
  • Gases: Air, Nitrox
  • User Changeable Battery: No
  • Features: Easy four button navigation, gauge mode, altitude and personal conservatism adjustments

Oceanic Geo 2.0 Dive computer Review

We've done all the work for you and found the best prices on the Oceanic Geo 2.0:

Our recommendations:

The Geo 2.0 is a nearly seamless integration between watch and dive computer. I have to sneak in dives where I can, so being able to see the current time underwater allows me to make sure I don’t enjoy myself for too long. The menus are a little confusing, but they are easier enough to learn and navigate. Overall this is a great dive computer watch for any diver.

Pro's and Con's of the Oceanic Geo 2.0 dive computer:

  • Best for: Entry level & Advanced
  • Gases: Air, Nitrox
  • User Changeable Battery: Yes

We've done all the work for you and found the best prices on the Mares Puck Pro:

Our recommendations:

I love the simple interface of the Puck Pro. Sure it made be a little big, but that translates to being easy to read in almost any situation. I dive as often as I can, and the battery definitely gets a work out. So, the user changeable battery is an amazing feature.

We've done all the work for you and found the best prices on the Suunto D4i:

Our recommendations:

I have been diving with Suunto computer more than a decade, and upgraded to the D4i to get rid of an additional hose when diving in cold water with a dry suit. The D4i feels more like a watch than a dive computer, which is nice, because I can comfortably keep it on my wrist during surface intervals. I love the free dive mode, as it helps me in my free dive depth and bottom time training.

Pro's and Con's of the SUUNTO D4i dive computer:

  • Best for: Entry Level and advanced dive computer
  • Gases: Air, Nitrox

We've done all the work for you and found the best prices on the Suunto D4i Novo:

Our recommendations:

For a multi-sport diver, scuba and free diver, this watch works very well in all situations. The small form and low profile don’t cause additional drag. For scuba, I love that it is air integrated so I have one less hose, and I don’t have to worry about a gauge dragging. It is great for traveling because I can easily put it on rental regs and don’t have to carry as much with me while on international trips.

Cosmiq+ Dive computer Review

We've done all the work for you and found the best prices on the Cosmiq+:

Our recommendations:


Overall, I was very pleased with the performance of the Cosmiq+. The screen has its drawbacks, but they are easy to overcome. The computer is light and comfortable. The battery only lasts about 6-7 hours but is rechargeable and easy to hook up with the magnetic charger.

In the end, you won’t find very many dive computers out there with the features and connectivity that the Cosmiq+ includes.

Pro's and Con's of the Cosmiq Plus dive computer:

  • Best for: All-diver

Oceanic VTX Dive computer Review

We've done all the work for you and found the best prices on the Oceanic VTX:

Our recommendations:

I really enjoy the Oceanic VTX. The led display and Bluetooth integration make this computer feel futuristic and high class. The menus and setting are very easy to learn and modify, and the bright screen is very clear while diving. The only downside is that the screen dims automatically making it harder to read, and in bright sunlight the display gets a little washed out.

Pro's and Con's of the Oceanic VTX dive computer:

  • Best for: Entry level & Advanced
  • Gases: Air, Nitrox
  • User Changeable Battery: Yes

Suunto D6i watch sized Dive computer Review

We've done all the work for you and found the best prices on the Suunto D6i:

Our recommendations:

There is something to be said about a dive computer that is as beautiful out of the water as it is in the water. Plus, the D6i has all the features I need for my recreational diving. The display is still easy to read and manipulate even though it is watch sized. The Suunto algorithms are more conservative than other computers, but I’m ok with that because it keeps me further away from dcs.

Pro's and Con's of the Suunto D6i dive computer:

  • Best for: Entry level and advanced
  • Gases: Air, Nitrox to 99%/3 Mixes
  • User Changeable Battery: No

Our recommendations:

The Mares Quad was a great purchase for many divers. t's a full feature wrist-mount computer that is affordable. While the computer is big, and not easy to carry around on the surface, it is perfect when underwater. The display is the easiest to read that I have dived with. Perfect for the diver who wants it all.

Pro's and Con's of the Mares Quad dive computer:

  • Best for: Advanced divers
  • Gases: Air, Nitrox, Multigas capable

Mares Matrix Dive computer Review

We've done all the work for you and found the best prices on the Mares Matrix:

Our recommendations:

The Matrix is almost the perfect size for a watch dive computer, and the weight is great. Diving with the Matrix is as easy and it's very reliable.  The digital compass is fool proof. The only down side is that I still have to have an analog pressure gauge.

Pro's and Con's of the Mares Matrix dive computer:

  • Best for: Advanced
  • Gases: Air, Nitrox
  • User Changeable Battery: No, but  rechargeable
  • Features: Digital Compass, full watch capability including daily alarm, dive profile visable during dive, PC and MAC interface

Best technical dive computer

Shearwater Perdix Dive computer Review

We've done all the work for you and found the best prices on the Shearwater Perdix:

Our recommendations:

All I need to say about this computer is wow. At its price point it seems a little high to be not air integrated, but once I got the computer I wasn’t the least bit disappointed. The large size isn’t comfortable out of the water, but is perfect in the water. I love that it is comfortable on either wrist which allows me more flexibility with the tools I take with while working underwater. The abundant information available makes me feel safe and more at ease on my deeper and gas-mix dives.

Pro's and Con's of the Shearwater Perdix dive computer:

Suunto EON STEEL Dive computer Review

We've done all the work for you and found the best prices on the Suunto Eon Steel:

Our recommendations:

The EON steel is everything a diver could possibly want in a dive computer. The large color display is easy to read and decipher the different information for the diver. I loved that I can custom the data I see. The price is high, but is worth paying for. I have never felt better protected when diving with a computer, and the durable construction dissolves fears of dropping or damage from falling tanks.

Shearwater Petrel Dive computer Review

We've done all the work for you and found the best prices on the Shearwater Petrel:

Our recommendations:

  • Amazon with worldwide shipping

Two huge features stood out to me when I picked up the Petrel. 1) The AA battery option makes my save-a-dive kit much easier to maintain. I use rechargeable AA’s which further decreases my cost of having to replace. 2) The 1000 hour memory is amazing. I use this computer for work and play, but being able to record every dive makes sure I am covered and backed up if there are ever any questions or issues with work. Diving with the computer is beautiful and easy. The large and bright screen never leaves me guessing on my air or dc times.

Pro's and Con's of the Oceanic Geo 2.0 dive computer:

  • Best for: Technical & Advanced
  • Gases: Air, Nitrox, Trimix
  • User Changeable Battery: Yes
  • Features: The battery is standard AA, large 2.4" display, bluetooth integration, Digital Compass
  • Pros: 35 hour battery life with a standard AA battery, and a full color led/lcd display.
  • Cons: Case is little bulky and has a definite industrial look
Dive computer prepared by diver

- Sergiy Zavgorodny

A dive computer was not something I really thought I would need at first.

I was quite happy to plan with my dive tables and logbook and spend the money on more dive trips.

So What's The First Dive Equipment You Need To Purchase?

When I started working and diving every day, sometimes 4-5 times, my computer became one of my favorite things.

Here’s why.

Here are a few Common Features you’ll like about your dive computer:

It’s on my wrist

Actually my first computer was built into my console, but that’s not so common these days. It is a lot easier to look at my wrist to get information about my depth and bottom time than to have to bend down and check my gauges all the time.

Heck, some computers even replace all your gauges and console entirely.

Having mine on my wrist means I tend to look at it a lot more often too. Some computers are even built into masks, giving you a heads-up display so you don’t even have to look at your wrist. Another win for streamlining!

Constant recalculation

Tables assume that you go straight down and stay at that level (or series of levels) for the time you planned exactly. But what if you spend a lot of time looking at a turtle at 18 metres (60fsw) and spend half the time at 24 meters (80fsw)?

It seems like a small thing but your computer will tell you how much more (or less) bottom time you will get and change your dive plan as you go.

Nitrogen Exposure

Your computer does not simply let you know the bottom remaining time for the current dive. It will also let you calculate your surface interval and plan your next dives.

A table does this great when doing only a few dives, but when you are doing a lot of repetitive diving every day you have to remember you still might have nitrogen in your body the next morning.

Here's more about Decompression Sickness.

I never seriously thought about the 10 hour ‘surface interval’ I did overnight until my (then new) computer told me I was starting my first dive in pressure group ‘C’.

Your computer will remember details about your last dives just like a logbook.

This is great for people like me who don’t like to get their logbooks wet and prefer to write it all down with a beer at the end of the day.

Some will even connect to your computer, automatically filling in an e-logbook and giving you detailed graphs and statistics.


There are various alarms that you can set on some computers to let you know when stuff happens.

I never want to hear the 5 minutes of bottom time remaining alarm, but it has been helpful sometimes when I was distracted. I use my safety stop one a lot, which I have set to let me know when I get to 5 meters (16fsw) and then counts down 3 minutes.

I also find the rate of ascent alarm useful, which lets me know when I am going up too quickly. This is especially good when I am teaching students to do a controlled emergency swimming ascent “if you start to hear beeping, slow down”.

It tells the time

Yep, whether I’m timing a student breathing from a free flowing regulator or trying to figure out when the bar will close I know my dive computer is there.

Not all watches work very well when regularly exposed to pressure at depth and not all computers can be worn around town. Is it useful to you having one device that does both?

Other Features

Air Consumption

Some computers wirelessly connect to a transmitter in your first stage and can give you information about remaining air pressure.

They will also tell you how quickly you are consuming your air and will calculate how much time it will take you at your current depth before you use it up.

Gas mixes/Oxygen Exposure

Another great feature available on some computers is keeping track of different gas blends and oxygen exposure when diving with enriched air and Nitrox. Some will even manage multiple blends and allow you to switch between them during a dive.


Some computers have an electronic compass.  They are supposed to be a little less sensitive to having to be perfectly level and can remember headings for you. I have heard mixed opinions about how useful and accurate they are.

Some computers have built in GPS allowing you to tag a specific coordinate to navigate towards – such as your dive boat.

User replaceable battery

Does your computer have to be sent in to a dealer to have the battery changed? These computers will cost you a bit more in the long term as you will have to pay each time.

If you’re not near a service shop when the battery goes be prepared to live without it for a little while whilst you wait.

Choosing your computer

Computers come in all sorts of shapes and sizes, have different features and big cost differences.

In some parts of the world they can be a status symbol (like the sexy Suunto titanium range) and in other places they almost never see them.

I always read reviews and talk to people about their equipment before buying anything. Think about whether looks are important, what features you need, how often you will use it and how much you want to spend.

Safety advice

Remember that your computer is only accurate about your own dive. Your buddy might go a little deeper or enter the water sooner than you. Always use the most conservative computer and have a backup plan just in case.

How divers rate us:


  1. David

    A few months after I started diving regularly I bought the Galileo Luna with air integration and I absolutely love it.

    The constant RBT (Remaining Bottom Time) is all I really need and it’s the first thing I check when looking at the computer underwater. Bar is nice to know, but RBT is constantly calculated and takes into account the amount of air I prefer to have when surfacing (50 bar) and the time I am supposed to spend surfacing from the depth I’m at right now. It might be a very relaxed take on my air reserve but since I’m not doing deco dives or multiple gasses (yet) I prefer this way of diving. I dive for fun and this gives me time to experience the world underwater instead of focusing on “boring” stuff.

    Like you I love the ascent alarm and quick access to a 3 minute timer. The compass, however, I find to be too slow – I prefer a non-digital.

  2. Arun

    I just bought a dive computer and will be using it for the first time next week in the Philippines.

    I have used a dive computer while doing the dives for my certification. At the time, having the computer was re-assuring. After that I never used a computer and always felt a bit uncomfortable.

    Now, I hope that I can dive without the worry about fast ascents, bottom time and safety stops!

    • Torben Lonne

      It really does give some pease of mind, but it’s always good to be aware and able to finish the dive without a computer. Just incase of a male function – although I’ve never seen one, it does happen.

  3. Andrea

    I still don’t own a dive computer, after 6 years of diving. Of course, I have used one before, and I would definitely want one. It helps a lot and makes your dive more stress-free. But I do not see a rush in buying one. I still manage to cope without one, and will make thorough research before purchasing one.

    • Torben Lonne

      Wow 6years and no computer, impressive. Do you follow dive tables or buddy/guides computer?

      • Altan

        Hi Torben,

        I will be starting my rescue diving in a few months. I have never bought a dive computer.
        Always used dive centre’s computers.
        What would you recommend for me please? Also what do you think about dive computers that have digital compass in ? Are they reliable ?

        • Torben Lonne

          Hi Altan,

          Nice, it’s the best course of them all. It’s so fun, and you’ll really see your skills develop afterward.

          As for a computer, I’m guessing you’re into scuba diving for some time and planning on sticking to it. Therefore, skip all the beginner once. You need quality and comfort: A new one is the Cosmiq+, it’s nice and the cost is fair.
          that said, I’ve always been a fan of the Suunto D4-6 models. Good quality lasts for years(I still have my old Suunto with some 10+ years on it).

          • Altan

            Hi Torben,

            Many thanks indeed.



  4. Perry Forsberg

    I believe that a dive computer must be the first you buy of dive equipment. It is critical to be able to dive safe and you have every opportunity to calmly log your dives with the correct information after the dive

    • Torben Lonne

      I agree! Completely agree!

      Besides my mask and fins(which I bought before I was certified) the computer was my first, and it have saved my life. In a ripping downwards current the computer was a lifesaver.

      • helmi

        I agree

  5. James

    I have learned to live with the changes that have made a C card a ticket for a resort dive. One of the things i do not disagree with is the dive computer. With so little time in the water a new diver needs something to think for him/her.

    Maybe an advanced class or a very good buddy will help that person learn to use tables.

    Why? Go on a $5000 dive vacation to somewhere off the tourist trail and have your dive computer/battery fail. How can that diver be independent and responsible? How can he/she continue diving?

    Computers are ubiquitous and will help the new generation of divers stay involved. So I am for them.

    Ex-instructor and a diver for 49 years.

    • Torben Lonne

      Hi James,

      I agree, and as one that have tried the running out of battery on a small holiday island, I can say it’s a bummer. Still I was able to keep diving, once I got a holed of a dive table, and the holiday was saved.


  6. John Jerrehian

    I understand what you are saying about a dive computer, (I spend a lot of money on two Atomic Cobalts).

    However, I still feel new divers should learn from their existing SPG’s and understand the basics of planning a dive and diving the plan. Too many just rely on an electronic piece of equipment, (that may need a new battery at the wrong time or they forgot how to use it). Looking at your console to see one’s depth, direction, air is all predicated to ones’ training. If one begins to rely on a “beep” because they are too deep or low on air I see problems.

    As much as I love my dive computer, I still feel the basic understanding and training of learning to look at one’s console at specific times and understand the diving dynamics of dive tables.

    It reminds me a little of GPS’s. It tells you where to turn, etc. but is one really paying attention to where you are going? You didn’t have to get the map out and plan your trip. You don’t have to pay attention to certain land marks or street names as they are told to you. Go ahead and watch what happens when it stops working during a trip…

    • Torben Lonne

      A agree with you for a great part, but I don’t understand why people can’t do both. And this is where training comes in. If you had good and thoroughly training, this won’t be a problem. Know your consuls, check depth, air, and your surroundings as often as you can.

      Regarding tables, I really hear what you’re saying and see the issue. Knowing the basic is good, but how often have you used it? I have never had the use of tables on a fun dive(without guests).

      A Bigger issue here, a lot of times divers go in a group lead by a dive guide/divemaster. And in the planning, the guide will say: “since I’m the only one with a dive computer we’ll just follow that, and you just stay above me at all times” – First off, at no time, will guests stay above the dive guide at all time. Second, what if someone gets the bend. This is where a dive plan comes in handy. The dive guide should do the plan following a table, maybe a multilevel table, and follow that or rent them a dive computer if they’re looking for more time/depth.

      Thanks for starting an interesting discussion.

    Just like John Jerrehian pointed out. You build from the ground up!

    It’s like learning to drive a car, any muppet can put “D” into dummy, very few (unless out of Europe) can actually *drive a car.

      Yeah, but that analogy is like trying to say only good engineers use slide rulers.
      Or good drivers use a standard transmission vs automatic.

      Can you do up to the minute calculations while underwater?
      A dive computer can and it’s more accurate.
      Especially if a diver becomes distracted by events/people/environment outside our dive plan.

    Computers fail on a pretty regular basis it seems —- at least get a second computer so that you dive two. Know how to use them if issues. Love computers, but just a piece of equipment. I have been diving 50 years now .

    Hello from Guam! I appreciate the effort you guys made to come up with this list. But I am still confused as to what is the best option for myself. I am in the market for my first dive computer, looking for something best for someone between beginner to intermediate (ie with Nitrox capable) functions – In the event I continue my scuba education I don’t have to look for another computer.

    Maybe a list of all the required or recommended functions and features to look for in a Beginner’s (ie PADI OWD certification) computer, functions for an Intermediate diver (ie PADI AOWD, Rescue) and Professional (ie Master Scuba upwards) level diver. I would like to see some sort of order and comparison chart for the functions and features with “o” and “x” denoting with and without.

    The “Best for”, “Gases”, “User Changeable Battery” are all consistent, but the “Features”, “Pros” and “Cons” are confusing because if you mention for example, “easy to read even in low visibility”, do I assume all the other computers are difficult to read in low visibility? Or similarly, “The battery is standard AA”, does that mean the other computers use “AAA” batteries or some other battery size “C” or “D”?

    So the pros and cons are not consistent to be able to compare. After your review of each computer, if you had it summarized in a chart/table with “o” and “x” for each function/capability and features, I think it would be easier to compare each computer with its pros and cons being obvious for each individual diver.

    However, I like your “Best for”, “Gases”, “User Changeable Battery”. Very easy to compare between the computers and narrows down the choices.

    All the reviews and comparable lists I found on the internet also do not make it easy to compare and decide what is best for myself. Just my two cents (or maybe a dollars worth? 🙂 … Thanks again for helping me narrow it some, but still confused which functions and features are recommended for my diving level and which computer has those functions and features. I will still be scouring the internet…

      Hi Edmond,

      Thank you for your feedback to our list and way of reviewing. We’ll definitely take this into consideration for next time we review the guide and update with more reviews.

      I still hope you were able to find a computer that suited your needs. If not, shoot me a message here and I’d love to help you out!

      All the best

    Take the computer outside the dive shop into the sun. If you have trouble reading it don’t buy it, I spent a lot on the Oceanic VTX. It’s useless if the sun is out. Trying to give your information on board a boat is very difficult. Also, when you’re at your safety stop it’s hard to read on sunny days. I spoke to a representative at Beneath the Sea Expo. He agreed that it was a problem and should upgrade. No thanks!

    23 years without a computer, I always had a waterproof watch and used the physics of diving just like my dad.

    But now it’s the worlds laziest hobby and commercial divers are out-numbered by the all the gear and no idea brigade.

    Been using the Suunto zoop, it’s cheap, cheerful, easy to use and read, too big to wear outside the water but you can read it in any condition.

      Hi Craig,

      Welcome to the dark side of diving. From here on out, it’ll only go downhill 🙂 Joke aside. I agree it’s a great computer that’s reliable and easy to use.
