I use Suunto EON wrist computer. Easy to use. Excellent LCD specially during my night dives. I bought a cheaper computer Aeris Dive Watch-It won’t sync with my Mac laptop. Suunto EON is flawless and easy to use. Worth every penny.
Cost of Suunto EON - $1440. If you really love diving and planning to be a divemaster someday, you don’t need to upgrade to any other computer because THIS IS IT. It can handle anything. Mixed gases, CCR and more.
