How to dive more safely, more enjoyable and save on air consumption
The fun and safety of diving are largely based on our underwater balance on scuba diving.
We are actually required to control our buoyancy so:
A – we can dive effortlessly and thus also significantly save air consumption.
B – we can easily control and maintain the depth of the dive and thus also to fit the profile page and dive planning.
C – Increase the level of safety during the dive since the diver comes out of the water more relaxed, less tired and with less nitrogen in the tissues.
An important saying in diving states that a safer diver is a more enjoyable diver.
For controlling our buoyancy underwater it is important to implement some of their critical impact principles:
We all know that the correct body position during the dive is lying down but not everyone understands why and actually also when …
When we want to sink, we need to understand the “water response” to the body of the diver and use it for our benefit. A vertical position (standing) “cuts” the surface of the water, can help our bodies sink by emptying the lungs. After we have sunk 2-3 meters and lay down, we will actually increase the surface area of our bodies in relation to the water. In fact, we will stop sinking without any effort and without help from the balance and actually prevent our bodies from going up or down in an uncontrolled way. Proper body posture makes us exert less energy, not use our hands for balance, swim at a pace that is convenient to us and not dictated by gravitational force and ultimately a allows huge savings in our air intake.
When should we actually use our inflator?
We will strive for little use of the compensator as this will prevent us from diving in a yo-yo fashion and will save us a lot of air that is unnecessarily wasted on unnecessary inflating. In the diving course, we learned that as we deepen we get heavier and heavier, the suit and the air compacted in the compensator due to the increase in environmental pressure will make us heavier as we get closer to the surface, the effect of environmental pressure will be greater.
It is important to remember that changing the volume in our compensator (or our lungs) has no immediate effect and takes between 3 to 5 seconds to get a response. You should always pay attention to our body posture, as changing from lying down to vertical position (also for emptying) will cause our bodies to rise or fall. As a general rule, we will strive to swim in the direction we want to reach. This principle should also be applied to our movement in the vertical axis. If we want to go deeper, we will swim toward the desired depth and will be ready to empty the expanding air while reducing the environmental pressure. A common misconception of novice divers is to inflate the compensator in order to rise and drain in order to deepen – causing a dangerous and undesirable chain reaction: an inability to keep up with the equalization rate and / or crash on the bottom/corals, or rising too fast skipping the safety parking, or other cases that can easily lead to panic and eventually an unfortunate dive accident.
Other factors affecting the balance:
The amount of weights that a diver takes with him at the beginning of the dive should be slightly more than the diver really needs, since the common aluminum tank loses about 2 kg of air during the dive and we should strive to get a little heavy to the safety parking to prevent uncontrolled ascension. Different compensators are equipped with inflators with varying degrees of inflation – be alert and sensitive to the amount of air that is inserted into the balance at the time of inflation. It should be inflated in small doses and wait 3-5 seconds for response while maintaining the correct body position. The movements of our fins in the water causes a certain lifting power and we must take into account that when we stop the movement we will be heavier and may have to compensate by adding a little air to the balance.
Remember to empty the same amount of air as you continue the movement.
Be sensitive to your depth change by your ears because it is very easy to feel any change in depth.
Cameras with diving packages that become very popular among divers who want to capture underwater beauty come with different packages each with its own float capacity, which can affect our buoyancy.
Remember to consider this and choose the physical size of the camera according to our diving capabilities.
