Dive Master Guide

Dive Master® runs exclusively on the Apple Watch Ultra® and will soon be available on the App Store. 

Dive Master provides real-time dive guidance in a clear and intuitive graphical format for certified recreational scuba divers.  

Launch Dive Master from the Apple Watch face by tapping the Dive Master icon. 

On Dive Master's main page, you can start your dive, change dive options, see your dive logs, and get help. Before you dive, set the dive Options by pressing the yellow Options button. 

Select the Option you want to set, starting with the Initial Tank Pressure, Reserve Pressure, and Cylinder Size.

Dive Master uses regional localization for pressure, depth, and other measurements. It automatically displays all interface text in your local language and adjusts distance and pressure measurements to match your country. 

Select your initial tank pressure.

Then select your reserve tank pressure and cylinder size.

Once you enter your starting information, there are 3 ways to start a dive: automatically by entering the water, pressing Dive Master's green Dive button, or pressing the Apple Watch's orange Action button.  

The built-in Help file can explain Dive Master's features before going in the water.
