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 short 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

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.

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 included 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 rubber 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.
