Suunto D4i Novo Review: A Great All-Around Watch-Size Dive Computer


. minute Read

The Suunto D4I Novo is an upgrade to Suunto’s popular D4i Dive Computer Watch, with a few feature upgrades. The Novo is sleeker and more stylish than the original D4I, and has a comfortable silicone band, making it even more appealing for daily wear as a watch.

It’s clear from the bright colors and integrated ability to display time in two different time zones that it’s meant to be a vacation watch, keeping you company on a beach holiday, in and out of the water.

The ability to turn it off is helpful in that scenario, so it won’t turn on in the water of a pool or when engaging in non-diving sports, recording false dives.

Freedivers and skin divers love the D4I Novo for its compact size and ease of use, and it’s a great all-around dive computer for beginner to intermediate divers. However, the price point is a bit expensive for a dive computer that doesn’t have a compass and doesn’t have a replaceable battery.

Our Suunto D4i Novo Rating

How does it Stack up?

Design: 8

It's sporty and stylish while still being incredibly useful. Silicone bands are very comfortable and dry quick out of water. However, the screen might be too small for aging eyes.

Functionality: 8 

It all the functions you would expect from a mid-price dive computer like Air, Nitrox, and even a dedicated Freediving mode. However, it lacks some more advanced features as well as Integrated compass. .

Ease-of-use: 9

The new 4 button user interface makes setting up and using the dive computer very easy. However, the small buttons on the computer might be hard to press while wearing thick gloves.

Price: 8

The D4i Novo is reasonably priced for a mid-Level dive computer and what it can offer. It is a great buy if you can afford it. 

What We Like

We love that the D4I Novo combines all the necessary features of a good, reliable dive computer into a compact and attractive wristwatch. It’s the perfect accessory for a scuba vacation, or for those lucky enough to live a full-time diving lifestyle.

The menu system is very intuitive.  you can grasp the key operations of the computer with only a few minutes of use. The four-button user interface also makes navigating options and setting simple.

We were also impressed with the display. Although it’s small compared to a full-sized diver computer, you can still clearly read the large digits on the dot-matrix display.  


What We Don’t Like

We didn’t like there is no ability to use multiple functions at the same time.  For example,  If you have the stopwatch activated, you cannot scroll through a menu. 

There is also no integrated compass, something we can easily forgive since the dive computer is in the mid-price range.

Changing batteries can also be a hassle since the batteries are not user-changeable. Battery replacement must be done by a professional or void the warranty.

  1. My D4i diving computer’s button on the top right fell off while I was diving So water went inside the watch and ruined the computer. Beware of Suunto, low quality and very slow customer support. Never buying anything from this brand again. Which respectable company has buttons fall off their watches?? Now they want me to ship to Finland, pay shipping, pay for diagnosis and for replacing the watch. No thanks, I’ll buy another new watch for the same amount of money from another better and more respectable brand with better quality…
