What customers say about "Key Specs"
Suunto D4i Novo Dive Computer
  • I have a small wrist so I use the smaller of the two bands that it comes with and have no issues.
  • Very light, can be used in daily life, too, included free dive and Nitrox mode
  • All the functions your would need for scuba and freediving diving are here.
  • The dive log is clear and the dive mode is also clear and friendly to beginner
  • For freedivers it's realy nice and usefull device with many alarms in depth.
Mares Smart Wrist Dive Computer
  • I bought this as an intermediate level dive computer for someone special. He loves to wear it as a generic watch as well as using it for diving.
  • I'm a new diver and bought this for a trip to Key Largo. It worked great. Fairly easy to use and not too bulky.
  • Extremely intuitive and easy to use. Much smaller than I expected. I ended up wearing it most all day every day without even thinking to take it off.
  • I love the backlit feature and the ease of changing from Air to Nitrox mode.
  • Not much larger than a large watch. Definitely much much better than a hockey puck.

What customers say about "Features"
Suunto D4i Novo Dive Computer
  • Without directions I was easily able to switch between Air/ Nitrox, and time time changes.
  • I purchased the sensor separately and it accurately displayed my air. Easily synched up to the sensor without me having to do anything so that was a bonus too.
  • I found it easy to read below and above the surface.
  • Displays are easy to read and there are a lot of features.
  • It was easy to set the nitrox percent, so this became more usable on a week long live aboard trip recently.
Mares Smart Wrist Dive Computer
  • Two button operation is very intuitive, display is easy to read, reasonably good watch functionality
  • A mid level device that is backlit, easy to read, costing less than 1/2 others -- easy to program and software can be updated readily
  • The sound beep alarm when acending too fast can easily be heard. The display is easily visible under water.
  • It really helped with my ascents by slowing me down, and keeping me at the proper depth.
  • Nitrox compatable is nice. I've used it on 40+ dives and it's awesome.
