OXYGEN / DEPTH / RISK

Dive Risk Planner

Estimate a simple time and depth margin from your own readings. Not a game telemetry integration, pathfinding map or guaranteed safe-dive calculator.

46 sec estimated spare time

Oxygen 135 sec − estimated return 55 sec − safety reserve 34 sec.

Vehicle depth margin: 20 m (within entered limit).

Planning considerations

  • The entered values leave some estimated task time, provided travel conditions and oxygen usage remain as expected.
  • Small depth margin: avoid descending further before upgrading or choosing another route.

Limits: this is arithmetic on manually entered numbers. It cannot model swimming speed, depth-related oxygen use, air tank changes, temporary disorientation, current cave layout, Creature attacks, vehicle hull damage or game-specific pressure mechanics. Always read the actual in-game indicators and turn back early.
