Saturation Diving Oxygen and Depth Calculator

How does the Saturation Diving dive calculator work?

Enter the values displayed by the version you are playing. The tool adds capacity modifiers, applies the entered drain modifier, reserves part of the available time, subtracts outbound travel, return travel, and contingency, then compares the entered suit rating with the target depth. It does not contain an unofficial equipment database.

Enter the values shown in your current game build. The calculator does not assume hidden game stats.

Planning estimate only. Live objectives, damage, leaks, revives, detours, and balance changes can consume more time than this model.

Which values should you enter?

Use values from the current in-game interface or your own timed test. Do not copy a number from an old video without checking that the same item and version are still active.

Input	What to enter	Why it matters
Tank capacity	Current capacity in any consistent unit	Forms the starting oxygen budget
Oxygen drain	Units consumed per minute	Converts capacity into time
Capacity bonus	Current percentage increase, if known	Expands the entered capacity
Drain modifier	Current percentage change, if known	Adjusts consumption up or down
Travel time	Timed outbound and return legs	Protects the route back
Emergency reserve	A percentage not spent on routine work	Absorbs interruptions and mistakes
Contingency	Extra minutes for delays	Keeps the plan from using every second
Pressure values	Suit rating and target depth in the same unit	Flags a target above the entered rating

If the interface does not expose a stat, leave its modifier at zero and treat the result as a planning model rather than a game fact.

What does maximum bottom time mean?

Maximum bottom time is the estimated time left after travel, reserve, and contingency are removed from the calculated oxygen duration. A positive result does not guarantee survival: damage, leaks, revives, wrong turns, objectives, and balance changes can consume additional time.

Use the result as a stop rule. When real conditions are worse than the inputs, turn back earlier. The beginner guide and verified progression guide provide source-checked context.

Why are no suit or tank stats preloaded?

Saturation Diving is officially described as a beta, and the checked public Roblox records do not publish suit ratings, oxygen capacities, tank prices, or hidden formulas. Hard-coding community numbers would make the calculator look authoritative after a patch. Player-entered inputs keep the formula visible and the evidence boundary honest.
