Cressi Leonardo 2.0 Underwater Single-Button Scuba Dive Computer, 3 Modes: Air, Nitrox, Gage, User-Friendly Menu - Designed and Made in Italy

This thing just works! It is one of only two computers I would recommend without reservation to occasional recreational divers like myself who dive only a few dozen times a year. It has a clear, easy to read display that tells you everything you need to know on one screen when you are diving. It allows you dive with Nitrox. The battery is easy to replace, and lasts a good while. The single button interface is actually very easy to use once you get the hang of it. Is there anything wrong with it? I wish the safety stop countdown included seconds to, not just minutes The backlight isn't the greatest, but I've never actually had trouble reading the screen on any dive. It also does not sync wirelessly to your phone or computer by itself. But at this price point, I honestly do not think you can find a better device. The Leonardo has become the backup computer to my Shearwater Peregrine over the years (the only other computer I would personally recommend without hesitation). The Leonardo matches the far more expensive and capable Shearwater device for accuracy and safety on all my dives. Given how stupidly difficult, expensive, and confusing dive watches can be, I wish someone had told me to just buy this watch when I started diving well over a decade ago! If you are a beginning recreational diver and don't want to spend a whole lot of money on a computer, get this one. If you can spend a little more, spring for a Shearwater.

Fantastic computer and extremely easy to use. I decided to buy a computer since have started diving frequently and found that computer aren't that easy to handle, at least for me that I am Advance Open Water Padi and didn't dive with gases yet. This computer is pretty easy to use, with its single button interface. I set it up very fast, I could choose between metters or feet, celsius or farenheit, air or nitrox, safety factor (I used the default since I am a 'healthy' person) and other parameters that I never used. Since it has 1 single button, the way to use it is short press and long press, where short press is to change the menu and long press is to edit something. Once I got into de water, it was pretty easy to read (I have 1 point astigmatism in both eyes), with long press I turned the light on for a couple of seconds. Also the best features imho, are the heads up when I go up faster than I should do... it beeps and complains, in the safety stop it indicates easily the amount of remaining minutes. I feel much more confortable diving with it. I have just come from a dive into the Blue Hole in Belize where we dove at 40m depth (131ft) and it was my first dive so deep and using this computer made me feel more secure. The standard view into the water is the water temperature, max depth, current depth and current dive time. If you want to take a look you could check my fedepia84 youtube account videos in Belize (the name is "Scuba Diving in Esmeralda spot, Ambergris Caye, Belize"). Or you can check this video at the minute 5:30 where I test going up quickly to test the alarm heads up: [...] (Note: if you above this note the "[...]" text is because Amazon removed the link, so you will need to search the name above or check my comment below on this review) The only little thing I think it might be a cons, is that the watchband is sort of long and is little annoying (check the screenshot and video) and in one moment I didn't notice that the watchband grabber got released... nothing happens but I could have lost it. Next time I'll make sure to grab it tightly.

Can’t go wrong with this dive computer. Functionality works as it should. Super easy to use. Easy to read at depths. Durability- it’s just as durable as the others. The computer is a one size fits all . Like I said, you can’t go wrong with this dive computer.

I've only taken it on two dives (100ft and Nitrox) so far but I like it a lot. My only regret is not purchasing the deal that came with the computer hookup ( the log review on the watch screen doesn't display the lowest temperature that it reached on the dive). The light isn't very bright but it's not necessary in the day time and at night it seems like it will be bright enough. The band is HUGE but has holes all the way down it so it fits on my very small wrist. There is a lot of hanging band though. I actually mount it on my forearm instead of wrist because I like to keep my compass down where the watch would go so the length of the band works well. I am very pleased with the 1 button design and am glad I didn't opt for other models that had 2 or more. It is large, easy to read, and easy to navigate through the different screens. I would buy again.

I was really hoping to write a favorable review when I first ordered this dive computer but unfortunately I am going to have to give it a 1 star rating. Overall it appears to be a well made piece of gear with easy to understand and use feature but ultimately all those are irrelevent if it is difficult to read the screen. I really feel that Cressi Sub missed the mark by not allowing for a higher contrast digital readout on their display. It is by customizable and the light display is nominal at best. It is unfortunate to say the least. After 40 years of diving on a regular basis for both work and pleasure I am fairly comfortable with my ability in reading gauges while on the water. For this reason and this reason only I have decided to return my purchase. Buyer beware, there are certainly more sight friendly alternatives on the market. If someone reads this that happens to own a Leonardo please feel free to comment on your experience.

El diseño es muy chulo y el color también. Me costo encontrarlo al ser una edición especial. Fácil de usar. Lo negativo que es para mi gusto demasiado grande

Too complicated to set I just wanted a big watch but this watch is for divers so I made the wrong choice even the set up to just see time is so complicated I am not sure what I I am going to do with the watch I can even set the time it is really complicated Regret regret regret

思った以上にデカく、ダイビング以外で時計で使う事は不可能です。 まだ1度も使っておりませんが、日本語の説明書がなく、理解をするのに少し時間がかかりました。2010年1月にグアムで初めて使ってみます。 画像は通常のG-SHOCKと比較して写してみました。

Amazing dive computer. Carried out perfect dives with it. No issues till 56 mtrs also.

Ich bin sehr zufrieden mit dem Tauchcomputer. Ich hatte beim Tauchen oder auch danach nie Probleme mit dem Computer. Durch den großen Bildschirm erkennt man auch alles. Die Akustik ist auch gut. Ich kann diesen Tauchcomputer sehr empfehlen.
