Comments about Cressi Leonardo Wrist Computer:

The Cressida Leonardo was my first computer which I used right through until the end of my Divemaster course. For the price it was an excellent option - a better range of anything else in the same price range.
Unfortunately I think my diving has grown past this computer. It was really the third item of dive gear I purchased - mask (and snorkel), fins then the computer. As soon as I did my nitrox course, the need for my own computer become obvious.
But now I'm spending more time in the 20-30m range and down to 40m. It has become obvious that the Cressi algorithm is very very conservative. Suunto computers are renown for being conservative - well the Cressi is one step beyond them. To give you an idea have a look at the results of the 2014 Scubalabs dive computer tests. Yes, the Cressi comes out as a recommended buy, but the test results also show that it is the most conservative of the computers tested.
Don't get me wrong - conservative is good. But my diving has changed and so have the capabilities I need from a computer (eg I now want gas switching).
All in all a good first dive computer
