Experiencing the sensation of being underwater like one of its inhabitants during the first time dive is a great occasion for a new diver. Veteran divers never grow tired of spending time beneath the surface. Many take full advantage of the best diving spots all around the world. Before anyone can enjoy such pleasures of the underwater world, it is required to have and use the right diving gear.

If you plan to go for the best gear then you must be prepared to invest a substantial amount of money. Diving equipment is so expensive that many divers can’t meet the expense of getting all the equipment at once. They have to gradually build up. A lot of divers purchase good used equipment. To get the best value for money on used items, a new diver asks for advice and suggestions.

When you become a member of a diving center or club, you’ll have the opportunity to be in touch with many experienced divers who will be glad to give you advice on diving gear and other equipment. Nobody wants to spend money by buying items that won’t keep or too used to be repaired and maintained.

Basic device for diving would consist of a mask, wetsuit, fins and regulator.

Good diving mask is necessary because it relieves the pressure exerted on you and allows comfortable breathing. Mask protects face and improves your field of vision. It comes in a variety of sizes and you must choose the one that is comfortably fit and snug. Divers who wear prescription spectacles will have to get a prescription mask.

A wetsuit also known as a diving suit is worn for entire body protection from cuts and scrapes possibly from equipment or pieces of coral or rock. The suit also protects against burns from certain sea animals. Wearing a suit that fits like a second skin allows efficient movement.

To make you swim faster and easier, fins are used. They come in different sizes and are designed to help preserve the diver’s energy as well as saving body oxygen.

The regulator is an important tool that you can’t dive without it. This item is not worn. The regulator is used to control the pressure flow of the air in the cylinders. It allows you to breathe easily.

Having proper gear is the only way a diver can keep safe. Even with the best and most cutting edge equipment a diver may only dive with a buddy. The idea is that the one will keep an eye on the other. If one diver encounters unexpected problems the other can either immediately assist or call for assistance. A sensible diver would never risk diving alone.

Anyone can practice diving and learn to be a safe diver. It all relies on the right education from a certified training center and well maintained equipment. Using the right diving gear would result for comfortable, safe and enjoyable dive.

Scuba diving is considered by many to be just another recreational sport that implies no risks but only having fun while swimming under water. The truth is that diving offers a lot of benefits to those who practice it but the sport also includes various issues, from accidents that can happen under water to physical conditions. Some may say that scuba diving medicine is a complicated domain but no matter how difficult it can be, the instructors and the divers should be aware of many of the major points that scuba diving medicine brings to our attention.
Our organisms suffer a number of modifications when they are under the waters at various depths. Compression is one of the things you will have to deal with while swimming for scuba diving. From this point of view, the speed of descent and the depth of the diving are very important factors. In order to be properly prepared to visit the world that you can find at various depths under the waters you need to know how to adapt to the conditions that you will find there. You will confront with various water pressures so you must be able to manage with the equipment so you will breathe correspondingly with the depth you are at. The purity of the oxygen you breathe under water should vary according to the depths; otherwise, you can end up by confronting with some unwanted complications.
Scuba diving medicine comes to help with diverse problems and diseases that can affect people who practice the sport while something goes wrong. Affections such as hypoxia can occur when people don’t use the pure-oxygen apparatus in the proper way and it implies a lack of oxygen so the patient is recommended to inhale pure oxygen among other treatments. Hyperoxia caused by the excess of Oxygen or hypercapnia characterized by CO2 toxicity are some other complications that can occur when it comes to compression while scuba diving.
The decompression of dissolved gases can also be a major concern for divers and scuba diving medicine comes with treatment in these cases too. The affection is named the decompression sickness and the symptoms are improved with the help of a chamber for decompression.
The differences of the pressure under water can be very harmful to the diver if he or she is not able to handle the equipment in the proper way or when other complications occur. These are some of the cases where scuba diving medicine does its work. Years of research made the domain reach a point where it can solve many major affections caused by improper scuba diving. Besides the physical state of the individual, the psychological state is important as well as situations such as being panicked under the water can lead to harmful things for that person. for both physical and psychological problems that may occur while practicing this sport, scuba diving medicine can bring the needed solutions.

When starting out scuba diving most trainees struggle with their buoyancy for a while. They are introduced to an alien environment and find that they are either floating or sinking. Unfortunately, many divers with years of scuba diving behind them still have problems with their buoyancy. In the shallow confines of a training pool bad buoyancy can be corrected by the instructor. When deep diving for extended periods of time this is not possible and poor buoyancy could be extremely dangerous.

The physicals laws of buoyancy are described by Archimedes Principle – that most of us encountered at school. It states that a body immersed in a liquid experiences an up-thrust on it that is equal in size to the weight of the liquid that it is displacing. Therefore if a boat displaces water equal in weight to itself then this will be experienced as a force pushing it upwards so that it floats on the surface. Conversely a stone will sink because being denser than water it displaces a volume weighing less than itself. The up-thrust is less than its own weight and it therefore sinks.

The boat is exhibiting positive buoyancy whereas the stone is negatively buoyant. We scuba divers do not want to flop on the surface or sink like a stone. We need to be neutral in the water so that with a lazy kick of our fins we can move up or down. If we floated we would have to paddle hard to duck beneath the surface and if we sank, we would always be struggling to compensate for the tendency to sink.

Neutrally buoyant means less effort and therefore less air consumption. It allows us the best control of our attitude within the water and is more comfortable than always having to swim to keep a position. Scuba diving enthusiasts get to be neutral by balancing their diving equipment. Often this is by trial and error and because a thick insulating wetsuit or dry suit is usually worn it will mean adding lead weights to the scuba gear. Often several kilos of lead are added by way of a weight belt or alternatively in weight pouches in the buoyancy jacket. The time to adjust weighting is at the end of the dive, when most of the air has been drained from the tanks. As the air that has been breathed can weigh a couple of kilos, depending on the size and configuration of tanks being used, the diver is at his or her lightest at the end of the dive and at this point must adjust their weighting to achieve neutral buoyancy. Carrying this out at the start of the dive could result in the diver being very positively buoyant by the end of the dive!

The weight belt and weight pouches can be removed by the diver quickly. The weight belt has a quick release buckle and the pouches are usually attached by Velcro. Thus, in an emergency the diver, or his buddy, can remove the weights and the diver will shoot to the surface where he can be rescued. This is a controversial rescue method, and the deeper and longer the dives being conducted, the more dangerous as an emergency procedure this becomes. A rapid ascent in only a few meters of water by a panicking diver after a twenty minute dive is likely to lead to a safe rescue. A similar buoyant ascent from 40 meters after an hour under water will lead to severe diving illness such as burst lung and decompression sickness. Even if a safe ascent is made, the diving computer used to monitor the dive will probably lock you out from diving for a day or more after a too swift ascent.

For such extended range diving it is often advisable to reduce the emergency jettison weights, to ensure that an emergency ascent is not too swift. Many divers have a combination of pouches and weight belts so that only part has to be removed to achieve slight positive buoyancy. A technical diver may even use integral weights in his twin set that cannot be removed. They know that a rapid ascent would be just as final as drowning. Some will wear a couple of removable kilo weights in small pouches – some do not.

Buoyancy is seen as a critical skill in scuba diving. Without good control, it is impossible to swim over delicate coral without doing damage or hard to hover while carrying out safety stops or decompression procedures. Being over weighted can be dangerous and even worse, wearing ill fitting or badly secured weights can result in unexpected buoyant ascents and the consequential damage this can do to a diver’s body.
