Cressi Leonardo Underwater Single Button Diving Computer, Created in Italy, Quality Since 1946

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.

I will never be a great diver, but I do love to dive and I do so wherever I can. What should a diver like me own and carry around? Mask and snorkel are what I've chosen but I've added this dive computer. Although the single-button operation seems clumsy, it works very well in practice and adjustments are easy. Directions could be much better, but that can be overcome. Screen is easy to read, back-lighting is sufficient, and the audible alarm is almost disturbingly loud, but it's an alarm! I usually dive with Nitrox and this computer handles that task with ease. I use the most conservative settings, although one can change to less conservative. The wrist strap is long, but there's a great keeper to control it. Using Nitrox means that I must use a dive computer and I dislike depending on the dive company. I do like being able to track my own diving, too, and start being more responsible for my own safety.Perhaps a professional diver would need more bells and whistles, but I don't. I recommend this.

I am okay with it, because it usually does its job: However, occasionally on the second dive it jumps into deco for no apparent reason. I have friends who have the same computer and have experienced the same problem. Every now and then they will put you into deco, while every other computer with the same dive profile, even other Cressi Leonardo's are well away from it. The by far more annoying feature is that it is really conservative about coming up too fast. It is in fact so conservative that it will constantly beep at you if you're diving anywhere that has a 3 foot swell passing over you. Very annoying if you're diving around rocks with waves crashing around them. Every time a wave passes over you it will beep, long and loud! It's a good first dive computer though. I wouldn't buy one again, but I also don't particularly regret buying it.

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.

Nicely made product, excellent size for viewing key information. Options on colors (nice for the wife) It's a value based product - robust and gives the data I need - I'm a minimalist and have little desire to do cave / technical / rebreather - wouldnt use the Shearwater...But...this is very conservative in it's dive profile. Still deciding if it needs to be returned. Maybe I went too 'value priced' ?

I spent a lot of time researching out different computers and have a tendency to price myself up a bit as I learn more about the bells and whistles. In this case I'm glad I didn't. I am an advanced open water diver and was ready to get my first computer before doing some more diving. I just got back from doing some dives in Bali using my new toy and it did everything I wanted it to, including a countdown for the safety stop. Maybe it is a little too quick to ring me if I ascended fast, but I don't mind being reminded to stay on the careful side. I also got the adaptor to download dive data and found the info interesting. The only thing I would change is I wish it would keep temp data for the whole dive and not just the coolest part.

As a rescue diver I have to say I love it. It's a very nice computer - for beginners as well as advanced divers. The main things I always check are: depth in meters, temperature and safety stop guidance (being 5m below surface and stay there is still tricky even if you are advanced)-which it provides at a glance and with sound signals. Even an experienced diver can get hitched in some drift currents and the warning beep with ascending or descending too quickly is always really appreciated by myself and buddies. And tbh that's all I really need. Have logged around 45 dives on in and was very pleased so I bought it for my father & husband as well. Easy to use with Nitrox too. I'm a passionate and frequent diver (had it nearly 1 year, 45dives logged) it gives me the information that I need and understand. I guess everything else would be an overkill. But there are so many settings (and even the port you have to buy separately - it looks like a interface from 1999 but still works) which you can get into but might not necessarily need. The other choice of dive computers I looked at started at GBP1000 so I rather invested that money in my Scubapro equipment and dive very happily with this one instead of knowing my heartrate or underwater blood pressure or Cholesterol :) And it looks pretty ace too. I recommend and love it!

Ich habe mir den Tauchcomputer 2017 gekauft und seitdem ca. 25 Tauchgänge gemacht. Hier meine Erfahrungen:BedienungDie Bedienung mit einer Taste ist ok, jedoch etwas gewöhnungsbedürftig. Leider erkennt die Taste nicht alle Tastendrücke. Uhr scheint aber an sich sehr robust zu sein. Das Armband ist wirklich sehr sehr lang und selbst mit einem 7mm Wetsuit und Handschuhe ist das Band noch lang nicht zu Ende.TauchgangDie Uhr ist auch in der niedrigsten Sicherheitsstufe wirklich sehr empfindlich was das Tauchprofil angeht. Selbst wenn man sehr vorsichtig aufsteigt piept die Uhr sehr sehr schnell. Alle anderen Uhren der Tauchgruppe piept noch nicht, aber die Leonardo schon. Klar ist die Sicherheit wichtig, aber wenn zu schnell und auch unnötig Alarm ausgelöst wird (Piepen), dann nimmt man die Alarme irgendwas nicht mehr ernst und genau da ist das große Problem, wenn man wirklich was ist.AkkuLeider war der Akku nach rund 20 Tauchgängen und innerhalb von 1,5 Jahren schon leer. Da erwarte ich einfach mehr.Tauchen mit GasmischenMan kann den Tauchcomputer mit O2 und Nitrox bis 40% betauchen. Hier funktioniert alles ohne Probleme.DisplayhelligkeitDie Displaybeleuchtung ist schwach und leider unhandlich zu bedienen. Bei guten Lichtverhältnissen ist die Uhr auch ohne Beleuchtung gut ablesbarPC-Software:Für rund 45€ kann man sich einen Adapter kaufen um die Daten der Uhr auf den PC zu laden. Die Software ist aber wirklich schlecht und wirkt sehr amateurhaft.Somit 2 von 5 SternenUPDATE: Kein Kundensupport!!! (-1 Stern)Ich habe über die offizielle Homepage des Herstellers Cressi wegen meines Problems zwei Supportanfrage ngeschickt. Doch leider hab ich bis heute nach 5 Wochen immer noch keine Rückmeldung auf keine der beiden Anfragen bekommen. Da erwarte ich einfach mehr. Daher nur noch 1 von 5 Sternen

I having been diving for around 20 years, initially as a BSAC Sports Diver, and then gaining the PADI Advanced Diver. These days I tend to dive around 10 times a year, predominantly overseas on holiday, or British waters in the summer.I needed a simple inexpensive dive computer. I didn't require syncing with my PC, as I can easily add the dive details. All I wanted was something that told me how deep I was, what my none stop dive time was (and how long I have left), warn me to do a safety stop, give the water temperature and keep an eye on surface interval (and allow me to plan my next dive). Everything else was a bonus. This computer does all of this, and more (mixed gas). Also, the screen is clear and easy to read. At 33m in dull conditions with maybe 5m vis, the screen was clear and did not need the backlight.The PC link is an (expensive) extra, but for 10 dives a year I can add the details to my dive log manually.It has a long strap so if you're got narrow wrists and dive with a shortie you may want to trim the strap! For me, with a 5mm wetsuit this was not an issue.The single button is easy to use, however, I don't really need to use it! Put on computer. Do dive. Look at screen during dive. Listen to beeps if it needs to tell you something. Look at screen after dive and write up log. None of this requires you to press a button. The depth, non stop dive time, dive timer, temp gauge etc etc, all show the same results as the dive master on my last dive, and his computer cost 3x as much. At the end of the day, why pay more, unless you NEED the functionality, which I don't.So, for me, it gives me everything I need at a price I can afford.

Imagine having a back light that can only be accessed on the surface? LIke, what? The computer is operated by pushing and holding one button, which is really clunky and leads you in the wrong direction regularly and you have to start again. Then there are other weird and wonderful functions that no-one needs and no surface interval calculation that I can find.

Box was ripped on outside and also inner parts had clear breaks where the computer had previously been removed. The scratch-guard on the computer's face looks like it was originally stuck on a small wrist-watch and only covered part of the screen. THIS IS A PIECE OF SAFETY EQUIPMENT. TAMPERED DIVING COMPUTERS COULD THEORETICALLY KILL.
