What's new

Version 7.2.0 · Nov 14, 2026

• Maximum bottom time: now also on a sidemount pair. • Maximum bottom time: extra tanks of the bottom gas are now breathed too and add time. • Maximum bottom time: the time now also stops at CNS 100 % and the OTU limit. A depth beyond the gas MOD shows an error instead of closing the app. • On a rebreather, "Create dive plan" opens a CCR plan with bailout. • Updated decompression calculations: the bailout is the richest gas breathable at the deepest depth.
