#1 Cheapest

Cressi Leonardo


The all time cheapest dive computer out there is the Cressi Leonard; despite being a fairly model still provides all the standard dive computer functionalities; displaying depth, dive time, no decompression limit and temp.

It also offers air, nitrox and gauge modes, plus the internal dive logbook is a decent size at 70 hours long. It’s one button user interface is simple although a little slow to navigate . 

As well as being the cheapest dive computer, the Cressi Leonardo is also the one with the biggest display, which has a diameter of 67mm which makes it extra easy to read, something beginners will find handy.

That said, it also means it is a seriously bulky piece of kit; you wont wan’t to wear it as a watch!

As a first time dive computer, the Cressi Leonardo is the best budget option but more experienced divers will find it’s features too limited and the design too big.  You can read more about super cheap dive computers here. 


  • Cheapest dive computer

  • Simple user interface  =  easy to use

  • Huge display  =  easy to read

  • Long internal logbook (70 hours)


  • Very large and bulky

  • Limited features

  • Cheap materials

  • Old, dated model

#2 Best for Beginners

Suunto Zoop Novo


Like the Cressi Leonardo, the Suunto Zoop Novo is a cheap and also fairly big dive computer; with a display diameter of 56mm it’s easy to read yet just a little less bulky than the Leonardo – though you still won’t want to wear it as a watch. 

Whereas the Leonardo has just one button, the Suunto Zoop Novo has four which makes it much quicker to navigate through settings. It also has an even large internal dive log with a formidable memory of 140 hours.

It operates in five different modes: air, nitrox, gauge, free dive and off and displays current depth, max depth, dive time, temp and no decompression time at the your current depth. 

There are also 3 levels of adjustment for more conservative dive profiles.

  • Cheap
  • Hug Dive Loge (140 hours)
  • Durable
  • Large display is easy to read


  • Bulky
  • Limited features
  • Lacking in quality compared to priceir dive comptuers

#3 Budget with Advanced Settings

Mares Puck Pro


The Mares Puck Pro is considerably smaller and more sleek than both the Cressi Leonardo and the Suunto Zoop Novo – with a display diameter of 48mm; it’s still bigger than more expensive dive watches 

It’s available in a variety of colours and as well as featuring air, nitrox and gauge modes like all dive computers, it also has a fresh water setting, salinity setting, residual nitrogen memory reset and multi-gas capacity. 

Being operated by a single button, it’s user interface is extremely easy and intuitive to navigate, albeit a little more time consuming than that of dive computers with more buttons. 

The logbook is just 36 hours, certainly less than that of most dive computers including cheaper options.

Established in 1949, Mares are a well known brand in the scuba diving community and their Puck Pro is a favourite budget dive computer option. 


  • Top seller – reliable and popular model
  • Different colours
  • Durable
  • Advanced features: salinity setting, multi gas and more


  • Short logbook
  • Still too big to be worn as regular watch

#4 Cheap Digital

Deepblu Cosmiq


Despite the fact it’s a lot sleeker and more modern than cheaper dive computers, the Deepblu Cosmiq is actually only a little bit more expensive.

It has a very nice 2.2 inch high contrast display which is easy to read even in the dark and incorporates blue and white to help display info stand out. 

There’s air, nitrox, bottom timer and freedive modes and it shows depth, dive time, time, no deco time and temperature. 

Whereas most cheap dive computers rapid ascent and safety stop alarms consist of a loud beep, when it’s alarms are triggered; the Deepblu Cosmiq vibrates and flashes. Some users like this but personally I find beeping more noticeable and therefore preferable.

Available in a range of colours, the Cosmiq charged via a USB magnetic charging device. Using the Deepblu App you can add details to the internal logbook which at 160 hours long, is bigger than that every other dive computer. 


  • Superb value for money
  • Stylish and sleek
  • Easy to use
  • Extra alarms
  • Huge logbook



  • Alarm only flashes and vibrates – no beeping makes it less noticeable

The D4i Novo gives you all the standard dive computer readings along with some extra features. to.

It’s the first dive computer on this pages list that can monitor your remaining air and current tank pressure although you have to separately purchase the Suunto wireless tank pressure transmitter in order to do this.

Things To Consider When Buying A Dive Computer

The best thing about choosing your own dive equipment, rather than using what is provided at dive centers, is that you get familiarized with your gear.

You get to choose things that will meet your specific needs and then get to nerd out and learn everything about the equipment.

With that in mind, let’s take a look at the key considerations to take into account when trying to decide what kind of dive computer you want to buy. 


#1 - Price range

Everybody’s budget is different and it is important to consider how much you are able to afford on a new piece of equipment.

#2 - Type of diving (needs)

The difference between recreational and technical diving changes the type of dive computer you will want to invest in. For recreational diving a basic, entry level computer, like the Cressi Leonardo, does the trick. For technical diving a computer with more advanced features is needed. The Mares Icon is an excellent choice.

#3 - Type of computer: watch, normal, console

If you are a frequent diver you may want a dive computer which doubles as a watch. If you dive more infrequently then this feature may not be important to you. Scuba computers can most commonly be worn around the wrist or attached to your tank. This is a preference thing and up to you which you enjoy most.

Features/Specs Explained


  1. Trimix Diving– A breathing gas consisting of oxygen, nitrogen, and helium used for deep diving (commercial and technical).

  2. Gas switching – The ability to change the gas mix that you are breathing mid-dive.

  3. Air integrated – allows the diver to check how much air remains in their tank.
