Diving in a lake or river? Need dive planning calculations in feet or meters of fresh water? Visit the in app “Settings” and choose the type of water appropriate for your diving conditions. You can switch at any time and your existing entries will be recalculated for the currently selected water type.
The default is to perform calculations for salt water (where one atmosphere of pressure occurs at 33’ or 10 meters). You can change this setting to fresh water (where one atmosphere of pressure occurs at 34’ or 10.3 meters). The setting will persist the next time you open the application. Units will be displayed as “fsw/msw” or “ffw/mfw” in the Planning and Best Mix tools. Make sure that the intended units are displayed before using the resulting calculations.
