How to choose, in 30 seconds
Buy the Shearwater you can afford if diving is your main sport. Buy a Descent if you want one watch for your whole life. Buy the Apple Watch route if you already own an Ultra and dive a few weeks a year. Buy Cressi or the Aqualung i-series if you are starting out and the budget matters. Then let the computer do the recording, and the logbook do the remembering: our dive logbook guide covers what to keep, and the app comparison shows why import support should decide which app you trust.
