– Cressi Erwachsene Giotto Diving Computer Premium Tauchcomputer, Schwarz/Grau, One Size

Really good piece of kit.

The screen is large, feature still resonable for a profuct designed in 2013 (consider the first mass production scuba computer 1987 - Aladin so this s more than a lifetime in this field) There is no firmware update possible. The backlight is verry weak, data pooling is once in 20 seconds. Most current hardware is pooling data at 5 or 2 seconds or each second(for freedive). However, is a big and reliable instrument for ocasional recreational use that will keep you safe if used corectly. Is not hard to use.

If there's one thing you want from a dive computer, you want it to work. Mine failed half way through a liveaboard diving holiday - on a dive. It just didn't recognise I was under water. Bad times. Cressi were completely useless when trying to claim under warranty (I have to send it to Cressi UK at my expense - then they send it to Italy - then it takes approx 7 weeks for them to look at it). I even emailed them a video of it not working - next to a working Suunto Zoop at 19m. It behaved as if I was on the surface (I could enter dive plan mode / PC Link / etc) - it was clear it didn't work and the battery was full. I "fixed" it myself by turning it off and on again (it is a computer after all), but have no confidence in it working properly for the future. Then there's the software to transfer your dives to a computer. It's atrocious - it's like you've taken a step back to the turn of the millennium. Download it for free before you buy anything (search Cressi's website for it). It won't work on a tablet and probably not a Mac - and it's not exactly straight forward on Windows. I didn't bother to send mine back - I'd rather put the tenner I'd have to pay for postage towards a decent computer and be done with this.

Great computer everything I need

Ottimo prodotto per un subacqueo inesperto ed alle prime armi come me! Innanzi tutto il prezzo ottimo, ho usufruito dei cosiddetti "usati" che in realtà sono nuovi ma con la confezione leggermente rovinata....beh! non ho capito bene dov'era rovinata....ma il prodotto era perfetto. Ottime le istruzioni, complete e facili da capire. Pratico l'uso con le scritte belle grandi che si possono leggere bene. Insomma tutto molto bene e subacqueo contento!

Great dive computer. Just used it on two dives Easy to read and helps with your deco stops

excelente, o melhor para quem faz mergulho recreativo

This is my first dive computer, and I found it easy to understand and simple to use… though the push / hold button sequences took a little practice (definitely recommend playing around with it for a bit before using it on a dive). At first I didn’t hear it beeping underwater, but once I recognized what it sounded like, it was loud enough to catch my attention. My only complaint, as a smaller woman, is the size — it felt a little large on my wrist, and I think I’ll need to trim some length off the wrist strap so that I don’t feel like it’s getting in the way. No issues reading it underwater. If you dive a lot you probably want to invest in a computer with more features, but this is a practical, (comparatively) affordable entry-level device for casual / occasional divers.

I just completed 10 dives with the Cressi Giotto. Overall I am very satisfied with the use and the functionalities it offers. I bought it after completing my advance open water and while I thought I would never use the nitrox feature, I am glad I had this option and I didn't need to buy a new computer. Once you spend some time going over the setup and the functions, it is very easy to use the computer. It is very easy to read underwater (I have used only once the backlight in high depth and very dark conditions) and it gives you a nice overview of all the information you need: current depth, max depth, remaining decompression time, safety stops and dive time. The log book function keeps all the data you need to know about your dive and anything you might want to add to your physical logbook (times, water temperature, etc.). The only thing I noticed (and it's not necessarily a drawback) is that when diving with Nitrox, the SF2 setting is very very conservative. It gave me a long safety stop (18 minutes at 3 meters for a max depth of 30m) and when I missed that it went crazy beeping and wouldn't let me dive again until I reset it and changed to SF0 safety factor. Good thing that upon resetting once, you don't loose any history of max depth or the logbook.
