Scuba diving is currently one of the most popular aquatic activities. It is a great activity for anyone who wants to be united with nature. It also opens a totally new perspective on how we view ourselves in relation to our surroundings.
The opportunity to dive under water is also a very invigorating activity. Since it is a different world, it seems like all of your problems are solved once you get to see the teeming life under the blue façade of the seas.
The nature below the surface of the water changes as the sun says its goodbye and as the moon starts to glow. Actually, most advanced divers would prefer to go on a night dive rather than a day dive. Why? Because at night, the sea is totally transformed and there are things underwater that you can only see at night. It’s like seeing all the high-rise buildings illuminate the happy streets of a city.
The beautiful scenery at night is something to look forward to. It is when all the nocturnal creatures become alive, giving the seas a different glow and color. Groups of minute organisms also reflect the light from the moon and create an effect that can’t be recreated by any natural or artificial means. The seas really come alive at night.
However, you should remember that night diving is only for experienced divers. It is most definitely not a walk in the park. The normal risks that a diver exposes himself to during day dives are enhanced at night. The darkness of the night also poses additional risks that aren’t present during the day.
We shall try to discuss some of the things that a diver must remember before night diving. If you are a beginner, you will want to read on so as to give youself some basic ideas on how to properly prepare and execute a night dive.
1. Rest well and eat well
Diving at night is physically more imposing than day dives. The coldness of the water will give a diver more stress plus the fact that the natural body clock is signaling the body to settle down and rest. Make sure that you have enough carbohydrates in your body to keep your body temperature stable under water. Carbo-loading can be done 2 days before you enter the water.
2. Orient yourself with the diving area
Aside from visiting the diving area beforehand, you can also opt to do a day dive on the same spot where you will be diving at night. This move lowers the risk of being lost at night and will give you more mobility because you are comfortable with the area.
3. Always have a night dive buddy
Perhaps the most important tip that you should remember is that you should never ever dive at night without a companion. Even if it’s not night time, you should also have someone to dive with you. Your diving buddy is your only hope against the wrath of the seas if something goes wrong. And, having a buddy will also make the experience more meaningful.
4. Get the right dive light
Essential equipment for night diving is a dive light. When choosing a dive light, you should consider the burn time, the beam width and the depth rating of the dive light. In terms of burn time, you should make sure that you fully recharge your battery if you are using a rechargeable one or bring extra disposable ones if you are using those.
Your maximum depth should also be lower than the rating of your light.
5. Get some glow sticks
Glow sticks are very useful underwater. You should attach some glow sticks to your air tank, or perhaps wrap them around your legs and arms so that you and your buddy can clearly see each other.
6. Know the rules
You can’t go around diving at night anywhere you want. Make sure that you inquire about the local regulations about diving at night.
Nothing beats diving at night. With the proper preparation and precautions, you should have nothing to fear and will look forward to seeing the majestic night seas.

A Guide to Night Diving
January 28th, 2010Scuba-Its All About Safety
January 12th, 2010Scuba diving can be one of the most exhilarating experiences. With every sport and recreational activity in order to get the maximized benefits, knowing your sport and safety is the best way to ensure the best experience possible.
Be in shape: This doesn’t mean you need to qualify for the Olympics but being able to swim comfortably in the water will undoubtedly take the stress off of the diving. Also it is advisable to have a physical done by your family physician to ensure that there are no medical conditions that may be effected by this activity.
Get your training: It is very important that you receive the proper training before attempting to scuba dive. Becoming certified is the first step to become an experienced diver. It is important that you ensure you have had all the proper training available for the kind of dive that you are attempting. Many resorts and vacation spots will offer a course in diving that is not extensive. If you decide to go diving after one of these courses remember not to dive lower than thirty feet. While scuba diving can be fun and a wonderful experience there are also risks involved and knowing these risks before attempting a dive is another precaution to ensure safe diving.
Breath: Do not hold your breath. This is a natural reaction when plummeting into a body of water but you need to train yourself to overcome that. You are hooked up to an oxygen tank and holding your breath may pose health risks. Breath slowly and exhale in a relaxed manner.
Never Dive alone: It is important to never dive alone. Diving with a partner will ensure that in case of an emergency there is someone looking out for you. Make sure to always to pre-check each other’s equipment and keep an eye out on each other during the dive.
The Weather: Weather is always an issue. Since the weather is one element that can not be controlled make sure to be on the lookout for bad weather and high tides. If the water doesn’t seem right to you or the weather seems to be picking up, it is always better to be safe than sorry. There is always tomorrow. It is a good idea to be connected with a diving operator as they will usually make the call regarding the weather. However, if you do not feel comfortable don’t do it.
Be careful when rising (exiting) your dive: Exiting a scuba dive is not as easy as merely rising to the surface as quick as you can. For shorter dives you will need to rise to the surface no faster then the air bubbles around you. Continue to breath deep and slowly and take your time. When exiting deep diving you may need to rest and decompress at certain levels to ensure that the pressurized air in your lungs has time to leave the body before they expand. Divers that rise to the surface to quickly can become very ill with decompression sickness also know as the bends.
Symptoms of the bends includes.
*unusual tiredness
*dizziness or vertigo
*pains in various ares (as the nitrogen bubbles can accumulate in different areas)
*tingling in arms or legs
*less common trouble breathing
*and in sever cases unconsciousness and coma
Decompression sickness can occur between 1-24 hours after a dive so it is wise if you suspect yourself or someone around you may be suffering from decompression sickness to take them to a medical facility as soon as possible.
Also you can develop decompression sickness if you fly or mountain climb after a dive. It is a good idea to refrain from flying for twenty-four hours after a dive.
These are a few tips to know before attempting to scuba dive. If done correctly scuba diving is a rewarding experience but if done without proper training or without properly trained individuals accompanying you it can pose a great danger.
