The Leonardo is a must-have for divers entering the sport and for those who 'just want to dive'.Leonardo is the first computer designed, developed and produced in Italy by our owned subsidiary, Cressi Elettronica.

What customers say about "Key Specs"
Cressi Leonardo Dive Computer
  • 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.
  • I've only taken it on two dives (100ft and Nitrox) so far but I like it a lot.
  • It's my back up and very in sync (time, depths) with my ScubaPro wisdom 3 console.
  • I have used the computer on a couple dives to 80 feet and the depth and time were captured in the history as expected
  • Used all through my technical course. It has a gauge mode and i asume it'd work well as a backup computer
Mares Puck Pro Wrist Computer
  • During ascent, it displays the rate in feet/minute and has a bar graph display as well. If you exceed 30 ft./min (or 40 if you go beyond a certain depth), it beeps to warn you and you have to slow down.
  • The rubber strap is a really good quality- not too stiff, not too sticky and with enough adjustment to fit over bulky suits.
  • Computer starts either manually or automatically with submersion, a nice feature. Fairly nice display, well laid out for each mode.
  • I just got it so haven't had a chance to use it. I did go through the settings, modes and features and it seems to be very straight forward in what it will do.
  • Just completed a weekend dive trip with seven dives using this computer. It was an altitude dive in freshwater, 60' depth, and 73 degree water.

What customers say about "Features"
Cressi Leonardo Dive Computer
  • 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.
  • Screen is easy to read, back-lighting is sufficient, and the audible alarm is almost disturbingly loud, but it's an alarm!
  • 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.
  • Cressi claims this watch can be used for free diving, but the ascent alarm still goes off even when Gauge mode is turned on.
Mares Puck Pro Wrist Computer
  • PLANNER is awesome. Go there, and based upon your last dive, SI, desaturation time, etc., it tells you, once you scroll to the depth you intend to dive
  • ALARMS are for rapid ascent (30 feet/minute), exceeding a safe pp02 for EAN dives, CNS=100% 02 toxicity, a missed decompression stop, and low battery during a dive.
  • It's easy to use, the display makes sense and is readable and it doesn't inundate you with too much info.
  • Underwater, the large face is very easy to read, and has a backlight if you push the red button.
  • All the dive plan calculations, dive times, depth, alerts/alarms, temperature, altitude adjustments, safety stop timer, and digital readings were spot on.
