Excellent computer

Excellent computer for the price!! A great computer for the beginner and advanced diver. Air and Nitrox with a "Gauge" mode. I have tried several dive computers and kept coming back to the Leonardo every time. Easy to operate and even easier after using the class that is included with the computer purchase. The display is very easy to read because of the large numbers. It may not be a big deal, but I like the fact that you can turn off the computer between dives. It still keeps up with the d...

22 dives and counting

Bought this computer without doing enough research and not knowing what to look for. The computer is okay but I'm surprised that for a beginner level it doesn't not have a timed stay stop. Will probably sell this one and buy one that has that feature. Sorry cressi.

Good Computer at a GREAT price.


from Fort Dodge, IA, US

The three factors in all my scuba purchases are durability, functionality, and price. When I buy equipment, I try to do my homework, balance these three factors and find the best product for the money. The Cressi Leonardo fit into this grid beautifully. It is not the cheapest computer on the market, but it is (at least in my mind) the best for the money. Leonardo has great features, is easy to use, and is priced below many models with similar features. The readouts are large and easy to see (a great thing for these ever aging eyes). Navigating through the various functions is a breeze.


Nice entry level computer


from São José dos Campos, São Paulo, BR

Very nice option for the price, the only 2 observation I have its that the wrist straps are very long, and it beeps for a minimal depth variation, even the more sensible ones. I though the alarm little bit over, but you get used.


Excellent budget choice for most divers


from Columbia, MD, US

I have done over 100 dives on this computer over the last 2 years, about half on air and half on nitrox, and while it is not perfect, I have been very satisfied. PROS: It is very affordable. Has a large display, and is easy to interpret underwater. It's conservative in its algorithms. The menus with the one-button interface are intuitive enough, once you get the basic hang of it. The build quality is good for the price. The battery is very easily user-changeable, which will save you a ton of hassle and money over the years. CONS: The one-stop interface is a pain in the butt when you have to cycle through a lot of dives in the logbook. There really isn't a logical way around that, because there is no "back" button. But hey, you are paying less than $200 for a sturdy dive computer. And it's not like you will be cycling through the logbook every other day, especially if you keep an external logbook (which you should!). The most recent dives are stored first in the queue, which helps a bit. It's bulky. No getting around that. But it's not heavy, and I really don't care about the bulk. The plastic lens protector scratches easily, but it's user repleaceable for about $5-10. Not a big deal. BOTTOM LINE: I was very happy that LeisurePro recommended this dive computer, and have been a happy camper with it.


One button pain with clunky computer interface


from 16365, PA, US

I bought this dive computer from the NYC store a couple days before a dive vacation. It is my first dive computer. I told the associate at Leisure Pro that I wanted something with a user replaceable battery, a backlit display, and the ability to upload my dives to my computer. I was going to purchase a Sherwood that was on sale for $270, but the associate recommended the Leonardo because it had all those things and was on sale for $200. Well, i found out once I was in Curacao that the single button is a pain in the but. I needed to change the time, and accidentally incremented the year to 2017. Having only one button (that increments in one direction), I had to push it 99 times to get back to 2016. I found this to be a pain with other settings. Also, when changing a setting, if you pause for more than a couple seconds the value you are changing automatically gets saved. This is a pain if you pause to think about what value you want to enter (which i experienced more when learning how to program/use the computer). My other major complaint is that in order to connect the Leonardo to a computer, you have to buy the clunky $70 interface that is bigger than the watch. It's cheap plastic, and uses a mini-USB connector instead of the more common micro-USB cable. When I bought the watch, the sales associate at Leasure Pro didn't bother to tell me that the computer inferface doesn't come with the watch (found out once I was on vacation). The things I do like about the watch are the large display and easy to read symbols. Overall, I am dissapointed with the watch, as well as the recommendation from the sales associate.


dive computer with style


from Montreal, QC, CA

Got this as a gift for my wife. She loves the design. A bit on a big side, however superb legiblilty under water. good conservative algorythm, adjustable and made in italy. should last long time. ****got a free gift from leisure pro, a video manual that I would otherwise be required to pay for*** btw. thumbs up to guys at leisure pro, especially Frank. All my local scuba stores cant even match the level od service these guys give. +++
