Divers find interesting new ways to explore the underwater world, challenge themselves, or simply increase the diving skills that may be of interest to learning more and more popular sport of free diving.
The Challenge of Freediving
During diving, snorkeling and year-to-day approaches to exploring underwater worlds, diverters from divers usually have different goals. Frequent diving scuba diving, calm observation of aquatic life and aquatic environment. Keepers, on the other hand, usually try to achieve depth or dive time. In fact, some years to become a world record is quite amazing. Of course, also keepers enjoy the beautiful underwater environment but our goal is to challenge ourselves to put ourselves to the limit.
No Lung Over-Expansion or Nitrogen Issues
A scuba diver is taught to never hold his breath underwater, but a freediver holds his breath underwater throughout his entire dive. Why is this possible? While the air a freediver inhales does compress during descent and expand during ascent, the volume of air in a freediver’s lungs is never greater than it was on the surface because he does not inhale additional air underwater. For this reason, freedivers need not worry about lung over expansion. Similarly, a freediver’s body does not absorb nitrogen underwater (there is no additional nitrogen to absorb) so freedivers do not have to concern themselves with maintaining a safe ascent rate, exceeding no-decompression limits, or making safety stops. Freedivers may ascend and descend as quickly as they please!
Little or No Gear
In order not to rely on equipment such as diving. Most retainers use some equipment, including fins, masks and snorkels; if the water is cold, they can be worn with a suit and weight. However, these devices are mandatory. Fewer devices allow the holder more personal experience with the underwater world.
Shorter Dive Times — But More Intense Dives
Freedives are significantly shorter than scuba dives. On a typical dive, Scuba divers can usually spend between 45 and 60 minutes underwater. An average freedive is only a few minutes. Why would anyone freedive when it is possible to stay underwater much longer on a scuba dive? For the rush! The two minutes a person spends underwater on a freedive are more intense than an entire hour on scuba gear. The short time a freediver stays underwater is achieved entirely through his own skill, without equipment to artificially extend his dive. The feeling of reaching a depth or time goal in freediving is exhilarating!
Ear Equalization Techniques Are Similiar
Scuba divers may find themselves surprisingly well-prepared for freediving, because there are many similarities between the two sports. Both freediving and scuba diving require that the diver is comfortable and confident in the water. Scuba divers who haved gained confidence underwater may find that freediving is an unexpectedly easy transition.
Many techniques learned during open water certification transfer into freediving. One example is ear equalization. Like scuba divers, freedivers must compensate for the pressure increase in their ears during a dive’s descent to avoid an ear barotrauma. In many cases, freediving techniques also transfer to scuba diving. For example, freedivers use different, more efficient equalization techniques than scuba divers because their descents are so rapid. Scuba divers may benefit from learning these techniques.
wimming and Relaxation Techniques
Good scuba divers relax, slow and calm underwater, and the same holds true. The ability to relax underwater is mandatory because the keepers must reduce the use of oxygen in order to extend their dive time. Divers have learned to stay calm in the water there will be a relaxing time to adapt to the year than to have become.
Finally, advanced relaxation techniques used by the keeper to expand them can be useful in diving dives. For example, pre-dive years become a great tool for breathing techniques that can become a divers before diving to calm yourself. The study year became a scuba diver who had breathing techniques that could actually help reduce his air consumption rate.
