How freediving can be useful for divers
Today freediving is becoming an increasingly popular hobby. A hunting method that has been practiced since ancient times, which people practiced in the very distant past, is undergoing a revival today as an exciting activity and is often referred to as the most rapidly developing water sport in the world.
If you are a scuba diver (scuba diver), and prefer to breathe underwater rather than hold your breath, freediving can still be very useful for you. Some of the skills gained in freediving training can be very useful when scuba diving, will help you become a more professional and confident diver.
1. Freediving will teach you basic skills before scuba diving.
The experience of holding a breath dive before starting scuba diving is a big plus for the future diver. At the time of the emergence of scuba diving as a sport, the possession of basic freediving skills was a prerequisite before starting a training course. These days, this is no longer a mandatory requirement, and some instructors, unfortunately, do not even test the ability to swim and stay confidently on the surface of the water.
To begin with, the study of freediving allows students to get acquainted with the basic equipment for scuba diving. Of course, there is a difference between diving equipment and freediving, but the general principles for using basic equipment (mask, snorkel, flippers) are the same. And they also need to learn for those people who have never used this equipment.
Regarding skills. One of the first skills taught when scuba diving is to clean the mask from water at depth. This is also a necessary skill when teaching freediving. So on the Freediving Level 1 course, ascent without a mask from a depth of 10 meters is one of the mandatory requirements. And having done this once on holding your breath, believe me, sitting calmly on the sandy bottom or in the scuba diving pool, it will be much easier for you to perform such an exercise.
The correct technique for swimming with flippers is also very important for a freediver who needs to get the maximum movement underwater from each wave of the flipper. Setting this skill in the future will help divers move more relaxed and skillfully underwater, getting pleasure from immersion and not distracting attention with the technique of stroke. The correct technique of swimming in the fins helps to better control the position of your body in the water, preventing the fins from contacting the bottom, coral or face of the partner. More technical and relaxed strokes allow you to spend less oxygen and increase the time spent under water.
2. Respiratory techniques as a way to increase the efficiency of air consumption
What do divers like to “measure”? Of course, the number of bars left in the cylinder after the dive;)
Novice divers are known for their ability to quickly expend air. Nobody wants to be the “weak link” who first “exhaled” their balloon and because of which the whole group had to emerge!
Scuba divers can significantly increase the duration of their dives by learning to control the breathing and breathing techniques that are used in freediving.
Freedivers who do not have balloons behind their backs should be able to control their breathing well to get the most out of a single breath. Having learned these skills, scuba divers will spend their air while scuba diving much more efficiently. By consciously controlling his breathing, the diver can significantly reduce air consumption, get tired less during the dive, relax better, and ultimately have longer, more pleasant and comfortable diving sessions.
3. Freediving teaches advanced purging techniques
As well as scuba divers, freedivers need to be able to equalize pressure in the middle ear, sinuses and mask when immersed in depth. Since freedivers do not have air tanks behind, they sink head first, deeper and faster – purging in freediving is much more difficult than in scuba diving. Purge is the biggest difficulty and limitation for many beginner freedivers. Therefore, freediving courses give much more attention and time to purging, and freedivers use more efficient and less energy-intensive methods of purging.
The best known are two purge techniques called the Valsalva Method and the Frenzel Maneuver. Scuba divers usually use Vasalva. This is the easiest technically purge method when exhaling from the lungs to the pinched nose. Due to this, air from the nasal cavity through the Eustachian tube enters the middle ear, equalizing the pressure in it. The plus of this method is its simplicity. Cons – low efficiency, a lot of excess tension, excessive load on the lungs. In addition, in freediving when diving deeper than 20-30 meters, when the lungs are compressed by ambient pressure, this method stops working.
