Aquatic Animal and Plant Life

First off we have to remember that our interaction with the aquatic environment is a privilege and responsibility. With this we want to minimize our impact on the diving environment by making sure that our interaction has no negative consequences, such as touching corals or disturbing local marine life.

With aquatic animals we must realize that most of these animals are timid and harmless to us, but defensively may hurt us in protecting themselves. Never tease or harass aquatic animals and avoid such things as feeding that can make some animals more aggressive. If aggressive animals are sighted, then watch them cautiously and exit the water if deemed necessary. When spear fishing, make sure to remove speared fish from the water immediately and respect local fish game laws.

Basic equipment for free diving

What`s basic equipment for free diving?

Dive mask. The most important feature of a free divers mask is that it should have the smallest volume possible. This is to facilitate equalizing the air space in reducing the amount of air necessary to do so and also helps in equalizing of ears and sinuses. The mask should also be as streamlined as possible with no dangling straps in order to reduce drag.

 

There are two designs of diving fins - “full-foot pocket fins” and “open-heel fins”. Open-heel design fins are not advisable for free diving, as they tend to not fit the foot and heel as securely as do full-foot fins.

For maximum performance, full-foot fins are advisable. They should fit comfortably without cramping or pinching your feet and toes. On the other hand, fins that are too loose easily fall off and are lost. If you plan to wear anything under your fins, such as socks for warmth and comfort, be sure to have them on when you try on fins.

 

The free divers snorkel should fit very close to the head so as to reduce drag. Also, the snorkel should not extend more than a 1 inch(2,5cm) above the head when the diver is in the relaxed, face down, surface resting position. The snorkel should not include a purge valve, which would increase drag. The tip of the snorkel should be fluorescent, or at least very bright, so as to facilitate easy identification, and most importantly, it should be comfortable to use.

History Of Free Dive

This my first post here, and i decide start write first post about  history of free diving.

Free diving  is generally considered to be one of the first extreme sports. Although unfair to categorize all of free diving as extreme.

Aside from those amazing individuals who engage in free diving competitions, for the vast majority, free diving is an enjoyable recreation.

Free dive or breath hold diving, is the earliest of all diving techniques, and has played a historic role in in the search for food and treasure, as well as military operations dating back thousands of years. The Hae-Тгу and Ama pearl divers of Korea and Japan are among the better known free divers.

Roman soldiers used hollow reeds as breathing tubes, which allowed them to remain submerged for longer periods while an enemies army would pass by unsuspecting of submerged Roman soldiers.

Many native peoples in the Caribbean as well as Polynesia have been free diving for conch, fish and lobster for thousands years.
