Free diving is a extremely exciting sport, especially when you first attend. Although extreme sports are attractive, you must make all kinds of preparations before participating. Only pay enough attention to basic safety rules during the exercise can you better enjoy it.
Whether you are well-experienced or a novice, you must be fully prepared for the sport. At the bottom of the sea, some small mistakes will ruin the event and even endanger your life.
1. Before you go free-diving, find yourself a evenly matched partner.
Never dive alone for you don’t know whether emergency will come to you at any time. In all dives, your safety diver is responsible for timing the dive. At half the expected time, he should begin his descent. A stand-by SCUBA set with organized lift tackle is required if you want to participate in a dive deeper than 30 meters. Different sea conditions also require that safety divers are more frequently spaced. Never dive at the same time as your partner. Keep in his or her observation all the time.
2. Never be over weighted.
Being over weighted is dangerous because it may cause equalization problem on ascent and descent. This will lead to unnecessary expenditure of effort. Especially when you are equipped with thicker suits for winter diving, this is particularly dangerous.
3. Never hyperventilate.
Hyperventilate means breathe at an abnormally rapid rate, so increasing the rate of loss of carbon dioxide. This may lead to blackout without warning underwater. Instead, proper breathe-up normally includes slow, deep ventilation, relaxation and concentration, without anything being overdone.
4. Don’t go diving when you feel cold or tired.
Cold, tiredness, fever, alcohol, and drugs can easily cause a blackout to a diver. So when you have one or several of these conditions, please set aside you diver plan until you feel better. Don’t go diving when you are either too hungry or too full. After a big meal, a large volume of blood that could be carrying oxygen to your digestive system rather than your brain. What’s more, drink lots of water before your free-diving to prevent yourself from the risk of Dehydration and blackout.
5. Never look down on descent or up on ascent.
Neck extension will cause difficulty in equalization on descent and on ascent will affect necessary blood flow to the brain and increase pressure in the neck, which may increase pulse rate. Also it is also contrary to a hydrodynamic position.
6. Don’t dive without diving buoy or flags.
Choose a diving buoy in a bright color, such as orange, yellow or red. The cover boat should fly the "diver down" flag, which attaches to your buoy. You can buy various kinds of diving buoy on Divtop to prepare for your trip. Apart from that, you should better carry yourself with some tools in case of urgent condition. A diving knife and safety reel can be placed in advance in your diving dry bag.
7. Know yourself well.
Learn to be relaxed underwater. At the same time in control. Understand your body signal and trust your body. You can let it tell you when it’s time to end the dive and come up.
