Review Summary

I bought three of these for myself and my daughters. Used on about 20 dives now and very happy with the performance. Slightly more progressive than Suunto or Deepblu Cosmiq. I was concerned with my aging eyes that the screen would be hard to read but no problems under water. I wouldn't call the interface intuitive and the manual can be confusing but once you play with it enough you get the hang of it. Great watch out of the water. I especially like the solar feature, no batteries and no charging. If it lasts as long as other Casio's, this computer could last 20 or 30 years with never a battery change. That inspires come confidence as battery changes and leaking seals are generally what kill other computers.
