Scuba Diving basics

Word of mouth is another very strong indicator as most people tell others about a bad experience.

After you have completed your course, unless you are totally focused and do it beforehand, you will want to buy your our scuba diving gear. There are literally thousands of different dive items on the market and each scuba retailer offers a selective few brands.

Normally these equipment lines are complementary so that the dive centre should be able to satisfy novice or experienced recreational divers through to highly experienced technical divers. If you are about to buy your own scuba gear take time to read our advice. Probably the most critical dive equipment is the regulator and buoyancy control device BCD combination. Take your scuba gear to face the shark The regulator should be selected on performance and reliability, that is ease of breathing at the depths you intend to dive to. Do a careful price comparison if your budget is critical. Your scuba dive centre retailer will guide you here. A BCD must be comfortable but most importantly it must be able to lift your face clear of the water at the surface. The inflator mechanism must be easy and fast to operate.

While it may lift you wearing a wetsuit, it may be overloaded once you take it off to pass it (with any integrated weight & cylinder) into the boat. Recreational BCDs are not designed for technical diving and should not be used for that purpose You will need to consider your instruments as well. Whatever your financial position you will need a submersible pressure gauge (SPG) and compass. It may be cheaper to purchase a dive computer rather than a depth gauge and timer / underwater watch.

Dive computers show dive and surface interval details as well as guiding your ascent speed. Some give integrated information on nitrogen absorption and gas consumption. With a computer it is easy to retrieve dive information so you can log your

dive. There are also Nitrox computers for sport divers and multiple gas computers for tech divers. Get your dive instruments in a console for easy reference. For regulators BCDs and instruments, check the warrantee. If you intend to travel, it should be worldwide. Some offer lifetime warrantees for parts. Beware buying product over the Internet, as there may be no warrantee. In many countries, scuba dealers will not honour internet warrantees, as the product was not bought through a licensed dealer and ownership is hard to authenticate.

 
You will want to stay warm and may only need a shorty wetsuit in the tropics. As you move further away from the equator, you might need a full length 5mm or 7mm wetsuit or even a dry suit. Try to buy the best you can afford as you will not enjoy even the most spectacular dive if you are trying to stay warm. Night diving is fantastic - only if you are warm. Comfort and fit are critical.

When you select your dive mask try every one on display.

Sniff in hard and listen for air leaks to ensure an exact fit. Additionally, press the mask in over your nose and brow to ensure there is no contact. Some mask lenses can be changed for prescription lenses.

If you wear glasses ask your scuba dealer which ones will take prescription lenses. Identify the dive masks that fit then try those few again. When you get to the best two, choose the cheaper one. If your mask does not fit well, you will not enjoy your scuba diving. Resist the temptation to buy a cheap snorkel. You need a good one so you can breathe on the surface face down. Accept the dive centre retailer's advice.

Fins are your propellers. Get fins that fit your feet properly, without placing pressure on your toes or the bridge of your foot. Always wear your own dive booties when trying on fins. Split fin technology is state-of-the-art now and worth every cent. Try for a soft or medium flex fin. If you want to be a technical diver, select firmer split fins. Get spring straps if your retailer has them

You will need weight unless you are negatively buoyant at the surface. When you purchase your BCD, consider one that allows you to carry weight in the BCD weight pockets rather than around your waist. Many women do get minor bruising on the hips through wearing heavy weight belts. With a dry suit you will generally need more weight than you would with a wetsuit. Contoured weights are preferable to slab weights.

You are now set to have fantastic scuba diving adventures. Enjoy the freedom of gliding in the ocean current along coral encrusted walls, through underwater canyons, exploring timeless shipwrecks or absorbing the stillness and tranquility of a freshwater lake.

The Things To Keep in Mind Before Buying The Scuba Gears

Exploring the world under the see is always a surreal journey. Along with the tremendous pressure, different temperatures in various levels of water always hinder to conquer the dream. But it is not an inconceivable task to plunge into the deep ocean with the scuba gears.

For the first few times you will usually hire the scuba gears and will compel to adjust with the rented problematic accessories. But when the aspiration to discover the ocean world grows up and up you will be tempted to buy your own scuba gears.

Before buying the scuba gears you must know your needs and always keep in mind these following things:

1) Snorkel: Snorkel is a breathing apparatus that helps you to breath under water without letting your head up from the water surface. The optimum length of snorkels is 30 cm (12"). It can be found in various designs. Normally it is J-shaped and made of rubber or plastic. It is mainly used in surface swimming before or after scuba diving.

2) Diving Mask: The diving mask is used to allow its users to clearly see underwater. It is not possible to the divers to view under water because when human eyes are in direct contact with water the lights entering the eyes are refracted to a different angle so that it becomes almost impossible to see clearly. Diving mask provides the air space in front of the eyes. Diving mask is made of durable and tempered glass with a rubber or silicon cover, which seals it with the diver's face to make it watertight. The divers can exhale within the diving mask. The best way to find the best mask is: first place it on your face (without the strap and without holding it by your hands), inhale gently. If it doesn't fall then keep it. Otherwise try another one.

3) Fins: The fins are used to move underwater. The fins are generally made from plastics but can be found often made from carbon fiber and fiberglass. According to the needs, the size of the fins can vary. Normally the scuba divers need large and wide fins to get rid of the water resistance to freely move.

4) Diving Suits: The diving suits provide the protection to the divers from the water atmosphere. There are different kinds of diving suits such as wetsuits, drysuits, semi-dry suits, dive skins and hot water suits. The diving suits should be chosen depending on the water temperature. Wetsuits provide the thermal insulation to the divers but they get wet. It is mainly used where the temperature is lying between 10 deg C to 25 deg C. Where the water temperature is between -2 deg C to 15 deg C it would be better to use the drysuits. The diver's body remains dry as it seals the body by neck and wrist. No water can enter through the dry suits. The diving suits are found in all sizes, so, it would be better to try which one fits you best.

5) Regulator: Regulator carries the air for breathing. It is a very important accessory at the time of the deep diving. This should have a second hose that is used for breathing out. Regulator is also connected with the buoyancy compensator.

6) Buoyancy compensator: The buoyancy compensator provides the life saving buoyancy both underwater and on the surface. This is essential to neutral the buoyancy. The diver has to choose which one should be taken according to his needs.

7) Watch: It is very much necessary to measure the depth and time while diving. It is better to have a computer rather than the watch. But you should consider carefully whether to bye a watch or a computer. The ultimate decision is yours.

The history of scuba diving is very interesting.

Scuba Diving Spearfish

Throughout most of time its been breath-hold diving, also known as free-diving. The evidence of early free-diving is the finding of sea items found on land and ancient pictures of divers. These civilizations used free-diving to spearfish and also in competitions. The Ancient Greeks are known free-divers. They used free-diving to hunt for

sponges and also in their military. Some of the early attempts in the history of scuba diving include snorkeling with hollow reeds, using air-filled bags and diving bells. Diving bells are watertight chambers on cables. The diving bell is designed to remain full of air as it is pushed under water, allowing a few divers to be transported. These methods were not very efficient, however, and did not nearly resemble scuba diving as we know it today. The reeds did not allow divers to go deep into the water and air-filled bags soon filled with carbon-monoxide as the air was exhaled. Diving bells did not allow the divers much mobility. The first scuba diving suits were used in France and England. They were made of leather and air was pumped into them from the surface with manual pumps. Once the discovery was made to use metal to make helmets, these suits were able to stand greater pressure. With air manually pumped into these helmets, divers were able to enter deeper into the ocean and the history of scuba diving was furthered. It wasn’t until the 19th century that the research was done to invent modern scuba diving as we know it today. Paul Bert of France and John Scott Haldane of Scotland, conducted scientific research on water pressure and our bodies limits regarding safe compressed air diving. At the same time, new technologies allowed for the development of air pumps, scuba regulators and other equipment. Scuba diving and its history were becoming more known. Throughout the 20th century, inventions in scuba equipment improved. Swim fins, masks and other scuba gear became available. In the 1950’s the public began to take interest in scuba diving. Scuba gear shops began to open up and the first wet suit was introduced. Popular movies about diving and ships, including Titanic in 1997, continue to interest new divers and inspire veterans of the history-filled and adventurous sport of scuba diving.
