Cressi is an Italian brand that was established in 1946. With over seven decades of experience, they are famous among the scuba community for delivering high quality products. 

The entry-level Leonardo model is no exception. All of the standard functionalities are available with clear displays for curent depth, max depth, dive time, NDL, temperature, and battery life. 

Alarms are both audible and clearly visible on the screen and can be adjusted to users’ needs. I also really like the large screen and single button interface as they make this dive computer very easy to use. 

The Cressi Leonardo is one of the most conservative dive watches on the market. Its users can rest assured that if you follow the prompts of this dive computer, your chances of decompression sickness are low.

The Cress Leonard Diving Computer computer comes in a variety of stylish colours, meaning you can use it to add to your customised scuba emblem! 


  • The high quality of Cressi products

  • Various color options

  • Imperial and metric display


  • No safety stop timer

  • The backlight is a bit dim

  • Size is bigger than a standard watch

#2 - Entry-Level Option


The i100 is Aqua Lung’s fairly basic diving computer but it is an exceptionally good one. It has an easy, clear display with a simple single-button interface to navigate through the menu.

This scuba computer has all of the standard functions a diver needs.: audible alarms, no decompression stop, air/nitrox mode, and gauge mode.

A very cool extra on the aqua lung i100 is the automatic change to free dive mode – it also automatically switches back to dive mode!

Freediving is becoming more popular and having this option on your dive computer is a really neat bonus that many other, more expensive dive computers to not have. 

Another beginner friendly addition to this dive computer  is that it retains data when you swap out the battery. Nothing is lost so you can rest easy in knowing your dive log is safe. 

The i100 is a superb option for newish divers due to it’s beginner friendly user interface and the fact it provides you with all the data necessary for a safe and effortless dive. 

It’s may lack some of the perks of pricier dive computers, such as a compass and backlighting, but still – this dive computer is more than enough for a first time user.

We have an entire page on the Best Dive Computers for Beginners as well as an article on How to Use a Dive Computer. 


  • Freedive mode

  • Automatic altitude adjustment

  • Easy-to-use interface


  • No backlighting

  • No compass

  • Interface cable is an additional high cost

#3 - More Pricey Option


By ‘pricey’ I only mean the least cheap of our favourite budget dive computers. The Suunto Zoop Novo is still more affordable than most other dive computers out there and for the extra money, you do get a great range of settings and modes.

All five modes (air, nitrox, gauge, free dive, and off) are displayed on the large screen. Plus, there are three different modes for how conservative you would like your dive profile to be.

One particularly cool feature is that you can access the stopwatch during your dive which is perfect to keep track of meeting up times between dive groups.

The dive plan mode is excellent for instructors to illustrate dive planning during lessons on how to use a dive computer. Users who enjoy planning their dives will also benefit from this feature.

The best thing about the Suunto Zoop Novo is that you don’t have to put in very much effort to receive the information you need. Just turn it on and jump in the water – the rest is taken care of.


  • Deep stop mode

  • Stopwatch

  • The backlight on time is adjustable

  • Many Modes & Settings


  • No built-in compass

  • Doesn’t show no dec time

  • Buttons can be difficult to push with gloves on

#4 - Top Seller


Mares is another beloved dive brand that are now offering a dive watch with the very same features that used to only be available in the top-end, very best dive computer.

The Puck Pro Plus comes with a a screen that is slimmed down for a sleek aesthetic, yet is still easy to read. The screen has labels around the edges which makes viewing the displayed information very easy.

However, the major drawcard of this model is its Bluetooth connectivity. You can upload your dive log directly onto your smartphone as soon as the dive is over. No more cables or waiting until you’re back with your PC.

Software on the watch can be updated as Mares releases newer versions.

The dive watch computer has all of the standard and needed features of a dive watch. Users can rest assured that this durable computer will last a long time without failing you.


  • Bluetooth connectivity

  • Slimmer size

  • Gas switching of two gases


  • No depth or bottom time can be set

  • Strap is fairly short

  • No free dive mode

  • Screen not as big as other dive computers

#5 - Most Compact


The Oceanic Geo 2.0 wrist computer sets itself apart as being a dive computer that is compact enough to be worn as a watch. There is  also a ‘time mode’ on the computer that will switch off all dive settings and only display the time. This option means you’re getting so much more wear for the price you’re paying.

Furthermore, the dive watch looks slick and stylish and comes in a variety of colors to choose from.

Oceanic is renowned for the dual algorithm feature on their scuba computers and the Geo 2.0 is no exception. Dual algorithms are beneficial for a number of reasons. The first is that you can monitor your buddies’ dive during your time underwater.

Another reason is that different algorithms can be used depending on how liberal/conservative you need to dive at a specific location. The conservative settings can be further adjusted in the modes of the watch.

Despite all this, this is not my favourite option of the cheap dive computers – it’s screen is not as big or easy to read as most others and it just doesn’t have so many modes and settings!

That said, if you’re number one priority is a compact dive computer that doubles up as a watch, then this is the best option. 


  • Compact size

  • Watch mode

  • Dual algorithm


  • Dive memory could be larger

  • The screen is smaller so can be more difficult to read

  • Anti-reflective coating could be better

Why are these Dive Computers so Cheap?!

Cheaper prices often make shoppers feel like the product may be inferior in some way. 

This is not the case with the dive computers listed above. However, there are some factors that may be lacking or not available because of the price point.

These factors do not affect the functionality and reliability of the watch but may be worth considering if you’re interested in tech diving. Or if you’re concerned about how you look.

Exploring the beauty of coral reefs could be one of the most mesmerizing activities on the planet.

Reasons for low price:

#1 - Look And Style

While hockey puck-sized computer screens make numbers easier to read underwater, they’re not the coolest looking things in the world. Budget dive computers are often lacking in that sleek, 21st-century look.

 You could say they look more like the kind of wrist piece you’d see worn by Austin Powers rather than the Bondesque style dive watches that are available when you start spending a lot more money. 

HD colored screens, changeable watch straps for out of water wearing, and chrome finishes are all details reserved for top-range dive computers.

However, scuba diving is an incredibly cool sport – don your ninja like scuba mask and wetsuit, your batman like weight belt and you’ll still look more dope than any mere beach bum, regardless of how big or small your dive computer is. 

#2 - Additional features

The basics are all there but features for more advanced diving are lacking. Air integration and digital compasses are the two features that stand out as missing. Tech diving is exactly as its name suggests – highly technical.

The needs of these divers can’t be met by the basic functions and features of entry-level computers. In my opinion, this is the real reason to be tempted to buy a more expensive and sophisticated dive computer. However, most people reading this won’t be a tech diver.

 Hint: If you don’t know whether your a tech diver, you’re not! Recreational diving does not fall under the tech diving category. 

Diving Squad Debriefing

Diving can cost a fair amount, and as someone who really does believe the best things in life are free, this can sometimes be a bit of a downer.

However, this list of the latest budget dive computer reviews can help keep costs low so that you can experience all the magic that our oceans have to offer.

Anything that means more time exploring underwater and less time worrying about cash gets a massive diver’s OK sign from me.
