Will you have enough gas? This planner estimates the gas a dive needs at depth, plus a rock-bottom reserve to bring a stressed team back to the surface. Treat it as a starting point, not gospel.
Gas requirement calculator
A simplified planner: bottom-phase gas at depth plus a rock-bottom reserve to bring divers up from depth at an elevated breathing rate. Always plan conservatively.
Reading the result
The bottom-phase figure is gas consumed at depth; the rock-bottom reserve is what must remain to handle an emergency ascent at an elevated breathing rate. Your real plan should add ascent, stops and a margin, and always respect the rule of thirds in overhead environments.

Instructor Insight
Calculators do not make a diver safe. They make the conversation visible. In training we always ask students to explain the number, the reserve and the decision behind it.

Instructor Insight
A checklist only works when the diver respects it under time pressure. We teach students to slow down before the dive, because most preventable problems start while everyone is rushing.

From the Training
One question students ask almost every technical course is whether planning gets faster. It does, but only after the diver stops skipping steps and starts recognising the pattern.
Frequently Asked Questions
Who is Gas Calculator for?
This section is for technical divers planning bottom gas, reserves and team requirements. It helps you decide whether technical gas calculation fits your current certification, experience and goals. The aim is practical: understand the next step, prepare better questions and avoid choosing a dive or course only because the name sounds exciting.
What should I prepare before focusing on technical gas calculation?
Before focusing on technical gas calculation, be honest about recent dives, comfort in the water, buoyancy, gas awareness and equipment familiarity. Bring certification details and any limits you already know. That makes the conversation more useful than a generic recommendation and helps us suggest a realistic next step.
How does technical gas calculation apply to diving in Cyprus?
Technical gas calculation matters in Cyprus because warm water, good visibility and access to serious dive sites let training move from controlled practice to meaningful dives. The environment is comfortable, but the standards do not change. We still plan the dive, brief the team and build skills progressively.
Can technical gas calculation support rock-bottom planning, stress reserves and decompression dives?
Yes, when it matches your level. Technical gas calculation can connect naturally with rock-bottom planning, stress reserves and decompression dives, but it should not be rushed. We usually look at your recent experience first, then choose a route that keeps the training useful rather than simply adding a bigger objective.
What mistake does Gas Calculator help divers avoid?
The common mistake is treating technical gas calculation as a label instead of a set of habits. Divers often want the destination, certificate or tool before the underlying skill is stable. Good preparation keeps the plan simple, exposes weak points early and makes the real dive calmer.
When should I ask GoToDive about technical gas calculation?
Contact GoToDive when you want to check a technical gas plan. Send your certification level, recent dive history, dates in Cyprus and the outcome you want. A short, honest message helps us tell you whether to train first, dive first or build a staged plan.
