Considering total gas volume before a dive is crucial for ensuring that divers have an ample air supply throughout their planned underwater activities. Adequate gas volume directly impacts a diver's ability to safely complete the dive, manage their ascent, and conduct necessary safety stops. Estimating the total gas volume required allows divers to assess their tank capacity and ensure they have enough breathing gas for their entire planned dive duration, taking into account factors such as depth, exertion, and the dive's profile.

By confirming that there is sufficient air supply, divers can focus on enjoying their dive experience without the stress of potentially running low on gas. This planning is essential for safe diving practices, as it not only enhances the overall enjoyment but also promotes safety by preventing situations where divers might have to prematurely end a dive or perform an unsafe ascent due to inadequate air supply.
