Everything you need to know about Spare Air in Scuba Diving

In the diving world, safety should always be the number one priority. One of the tools that many divers choose to increase their peace of mind underwater is the Spare Air. In this article, we will explore what Spare Air is, its features, its usefulness in emergency situations and some considerations you should keep in mind when choosing one. 

What is Spare Air? 

Spare Air is the benchmark emergency air supply equipment designed to provide additional air to divers in critical situations. Compact and lightweight, this device can be easily carried on any dive and has the potential to save lives if an emergency arises. 

Spare Air Features 

Size and portability: Spare Air is known for its compact design, which makes it easy to carry. It is lightweight and can be attached to the diver's jacket or worn on a strap, making it accessible at all times. 

Capacities available: Generally, Spare Air is available in various capacities, such as 3, 6 and 9 cubic feet, allowing divers to choose the option that best suits their needs and the type of dive they will be doing. 

Easy to use: The system is designed to be intuitive; divers can quickly access the air in case of emergency. 

Using Spare Air: Can it help to reach the surface? 

Spare Air provides air for a diver to safely ascend to the surface in emergency situations. Although not intended for prolonged dives, its air reserve may be sufficient to complete a controlled ascent, avoiding panic scenes that could lead to safety incidents. 

Can Spare Air supply air to a buddy? 

One of the important considerations when using Spare Air is that, in cases of emergency, it may not be practical or safe to share air with another diver. While some models allow this option, it is generally recommended that each diver have his or her own air supply system. In the event that a buddy needs air, it is more effective to make the ascent by sharing air from one's own tank with the octopus or alternating breaths with the regulator's second stage. 

Spare Air: With or without built-in pressure gauge? 

When choosing a Spare Air, the decision to opt for a built-in pressure gauge or not depends on the diver's preferences and needs. A pressure gauge provides an instantaneous reading of available air, which can be extremely useful for dive planning and for knowing exactly how much air is left. However, models without a pressure gauge are often simpler and lighter, which may appeal to some divers. The choice between a model with a pressure gauge and one without should be made based on the diver's experience and the conditions of the dives he/she frequently performs. 

As a conclusion we could state that the Spare Air is a valuable complement to the safety of any diver, and its use can make the difference in cases of emergency. The ability to surface with additional air, along with its portable features and ease of use, make this device a logical choice for those venturing into the sea. Remember that, as with any diving equipment, it is vital to familiarize yourself with and practice its proper use to ensure maximum benefit in critical situations. 

Other uses of the Spare Aire 

It is important to remember that the Spare Air is emergency equipment during dives and is not equipment for performing dive maneuvers such as unhooking the anchor or leisure dives.
