Decompression Schedule

Auto-Updating Deco Tables

The one-plus-one rule is applied automatically — always rounding up to the next deeper table depth and next longer bottom time. Each diver has their own live schedule that scrolls as the timer advances.

Surface Decompression

Sur D O2 Chamber Profile

When SurDO2 is indicated, the app automatically generates the full chamber decompression profile — showing compress depth, O2 periods, air breaks and final ascent. Updates live as bottom time changes.

How it works: The profile auto-generates from the looked-up SurDO2 schedule. As the diver's timer advances into a new bottom time bracket, the profile updates automatically. 0.5 period = 15 min O2. Each full period = 30 min O2 + 5 min air break.
