Dalton: Dive Gas Calculator

Dalton 1.3.1 • Dive Profile Advisor: if your SAC unit was cu ft/min (the default unless your device’s Measurement System is set to Metric), re-check any plan made with its gas volumes in an earlier version, including shared result cards. Segment, transit, total and stress-factor volumes were shown in cubic feet but labeled “L”, so they read about 28 times too low. They now show liters. SAC rates in L/min were not affected. • Updated for iOS 27. • Corrected gas calculations and clarified when no mix can be recommended. • Shared calculations preserve their inputs. Automatic gas selection in dive profiles is consistent across platforms. Verify calculations independently before diving.
