Product Comparison: Aqualung I200 vs Mares Smart

General Specifications
About the Products
The i200 is an intuitive, sporty computer with an easy versatility. With its fresh design, you’ll find yourself wearing the i200 as an everyday sports watch that is ready to dive when you are.
What happens when you add the superior sharpness of segmented characters, clarity of a perfectly laid-out display, and top it off with ergonomic advantages of two buttons? You get Smart, probably the smartest computer on the market.

What customers say about "Key Specs"
Aqualung I200 Scuba Dive Computer
  • I use it as a watch as well as a dive computer.
  • This is a amazing dive computer. Love how it fits, and is easy to see. Wearing it as a watch, and computer!!!
  • This is my first computer. I bought mainly for free diving, but I do not rule out scuba in the future.
  • Stylish design, already dived together everything is fine, I have an integrated console, I want to buy a wristwatch the same
  • it's a really nice and easy to use computer, elegant to wear, a little gem at a really competitive price!
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"
Aqualung I200 Scuba Dive Computer
  • Once set up, it's wonderful, a breeze to use and switch between modes, easy to read even deep on a free dive
  • Easy to use and read while in the water.
  • A nice feature is the dual time so I can see both the time at home and at a remote location.
  • As a dive computer it is excellent, easy to read and lots of features.
  • The 4 button controls make menu navigation easy. Screen display is large and easy to read in all light conditions.
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.
