Cressi Leonardo dive computers side by side

In the ultra-budget section, you will not find many worthy alternatives to the Cressi Leonardo which I could actually recommend to any serious diver.

It is easy to use, looks decent, does Nitrox and normal recreational diving well and is priced super competitively.

Our Cressi Leonardo review

Below you find everything you need to know about the Cressi Leonardo, its features, specs and what we like, and don't like about it.

This dive computer is used by many of our students and they are happy with it.
It is marketed as a scuba diving computer for beginners by Cressi themselves, due to the straightforward one-button design.

It will calculate your dives, give you accurate accent rate warnings, and even includes Nitrox functionality.

If you are an instructor or dive center looking for rental equipment, the Cressi Leonardo has the super useful residual nitrogen reset feature.

This means you can reset the computer after each student and therefore don’t need to use two different computers (as long as your students dive one after the other).

If you have read some of my other articles, you know that I am not a fan of the Reduced Gradient Bubble Model that many brands incorporate nowadays.

While Cressi does disclose some of its details, an RGBM will never give you full control and understanding of the inner workings of the decompression algorithm.

The Cressi Leonardo is one of the best choices if you are not willing to spend a lot of money on your scuba diving hobby.

There is a good reason it’s both in the list of the best dive computers 2022 and the best dive computers for beginners!


In the budget dive computer range, the biggest competitor to the Cressi Leonardo are the Mares Puck Pro, as well as the Suunto Zoop Novo which both feature great displays and lots of features.
