Deep Sea Diving
If snorkeling is something you enjoy when you go to the beach then why not learn how to deep sea dive? Deep sea diving is a skill which allows people to do commercial or sport like activities under water for a variety of reasons. Whether it be exploring shipwrecks or help in repairing or constructing a structure underwater, there are many jobs that a scuba diver can do. It takes a few lessons to learn the basics of deep sea diving after which you are qualified to explore the ocean deep waters.
It is recommended that you should buy and wear proper scuba gear and take lessons from a fully qualified deep sea diver before venturing into deep sea diving alone. You need to learn about the equipment you use, as well as the maintenance and safety of not only the equipment but your surroundings when undertaking deep sea diving.
Before venturing into any dive you will be asked if you want to be an amateur diver or do you have the seriousness to be a professional diver. The certification process is quite similar although there is a difference in the required certifications for divers who want to go down the professional route.
How to Deep Sea Dive
It doesn’t matter which type of diver you become, training IS essential. Learning diving skills to become proficient is essential because you can risk to your life and the lives of others should you get into some difficulty. Some places offer basic courses (scuba diving) for children (8+) and adult beginners’ courses and all are covered by PADI instructors. A typical lesson lasts about an hour in the water and the depths is normally not greater than two metres and are designed to suit your needs and capabilities.
Advance courses will have more in-depth training which comprises of a few sessions, a mock exam, the exam itself followed by a certificate of qualification. There are usually a number of courses depending on your skill level and requirements. Deep sea diving isn’t just for those who have 100% able functioning bodies, watch Sue Austin doing her deep sea dive.
Buying Diving Equipment
Although the initial outlay to buy the necessary equipment for deep sea diving can be expensive it is worth bearing in mind that diving gear can last for a long time. The most expensive part of the apparatus is the air compressor which is used for refilling the air cylinder.
Drysuits allow the diver to stay warm and dry when scuba diving in cold water. Drysuits are zipped and have waterproof “gaskets” around the neck, wrist and ankles and most come with attached boots. The gaskets seal tightly against body and keep the water from coming in. Most gaskets are latex, so any divers who are allergic to latex need to bear this in mind. Drysuits allow room for the diver to wear thermal undersuits underneath for added protection from freezing temperatures. Should your drysuit get damaged, there are some companies that have a repair service.
Here is a very good review of the Neoprene v’s Trilam drysuit from scubaboard.com
Wetsuits are designed to keep you warm while in water by allowing a small amount of water in to warm up to body temperature. The thicker the neoprene the warmer and less flexible it is. Full-body wetsuits are rated by two numbers which looks like 4/3 or 3/2. The first number represents how thick the wetsuits torso is and the second shows the thickness of the neoprene on the extremities.
There is an ongoing debate about which suit should you wear. People choose wetsuits for comfort, price and temperature of the water (shallow dive or scuba dive)
Dive boots are made from thick neoprene material from 4mm to 6.5 mm (5mm being most popular). The boots are designed to protect the diver’s feet from freezing temperatures and enable the diver to walk over sharp and awkward surfaces.
Dive Gloves are worn to give protection, comfort and warmth for the diver. They come in a range of thickness from 1.5mm to 6mm. Generally the thinner the dive glove the more flexible it will feel but less protection against cold temperatures.
Full foot fins are ideal for warm water diving and it’s like an extension the foot. If it’s properly fitting the fin is easy to flick as the diver swims so it is a lot more effective. Read more here about the different fins you can buy.
It should be noted that every snorkel mask will not fit every face. When determining proper a fit on a mask, the mask strap should not be used. Simply place the mask gently to the face and inhale slightly through your nose, holding your breath. You also have to consider the tube diameter and size as well as the mouthpiece.
Helpful Hints and Tips
Before heading to a major diving school it might be worthwhile visiting the local diving shop. If you are not looking to be a professional many diving shops may offer training for an Open Water Certification.
If you have medical requirements it is essential that you seek medical advice first. You will also be asked to sign a document at the diving school. Please note that deep sea diving requires a lot of physical exertion so there is an increased risk of injury.
