Scuba Tanks

            Limits for divers carry tanks of the human body provide a breathing gas at ambient pressure to overcome. The tanks are also known as a cylinder or bottle and is usually in the recreational diving breathing gas is air. Some non-divers will move the tanks as oxygen tanks or bottles, but this is false - Oxygen is toxic if inhaled at high concentrations of oxygen in deep and pure is not used in recreational diving.
            The cylinders are almost always made of steel or aluminum, the latter the advantage of being corrosion resistant. While the original material is steel, which is widely used throughout Europe, it is customary to make aluminum bottles in the United States and the Caribbean.
            Aluminum tanks suffer disadvantages, however - as it is softer than steel, it tends to be damaged by rough or careless treatment, and because the walls are thick to be bigger and heaver tanks needed during a comparable steel tank. However, if the tank suffers from internal corrosion of the oxide layer prevents further corrosion protect the tank - in a steel tank that is not the case.
            Usually worn on the back of the divers, a bottle of compressed air to the BCD (BCD), or a jacket and attached to the top of the bottle is attached to the first step. The main port for the first stage, the terminal A, but less frequently seen in Europe, the option-Din connector - it provides a strong seal the terminal A.
             The first stage regulator supplies air to the BCD - the air is released or expelled by the diver neutrally buoyant, chest varies with depth - and the air pressure gauge that is nowadays often included in a dive computer. It also provides air into the second stage, at an average pressure which is reduced by the second level of the ambient pressure to breathe diving. The standard configuration for the second step in modern diving equipment is in the same housing as the mouthpiece.

Scuba Wet Suits

            Scuba wet suits were not taken seriously until World War II and the advent of Navy Frogmen (SEALs), which was one of the most effective weapons of war America. On any measurable basis, costs for operations against the cost effectiveness, man to man, or kill a total of reports has exceeded expectations at all levels of the seals. Once identified, the military put a lot of time and money in improving the effectiveness of its frogmen. This meant improving the design, efficiency and durability of wet suits.

            There is a controversy that, over time, whether wet suits, had developed to keep dry. Sounds like an implementation of a joke, but it is not. Are all U-boats, protective clothing, rubber called combinations. The controversy was whether the loss of heat could be controlled better on the diver's body when the skin is dry or combination did not. It was Hugh Bradner who is credited with the first wetsuit in 1952. Mr. Bradner was actually working as a physicist at UC Berkeley Radiation Laboratory, where he was testing the reflexes of shock waves on unicellular material and was invited to attend a conference of the float. His concept was that the skin of the diver does not stay dry to prevent heat loss when the insulation used in the wet suit on the air in the material of the suit was get trapped.
             With the French invention of the Aqua-Lung, was an underwater breathing apparatus (SCUBA) used in the war and eventually led to investigation teams to many mysteries of the ocean to explore. Once it began, was the urgent need for the combination of painfully obvious by the divers suffering from hypothermia after a few dives. The divers tried everything from greased long johns remains Costumes Air Force survival, and the Bradner wet suit. Bradner was the first to use a material similar to the single-cell type, he worked at the Radiation Laboratory in his suit. The material comes from a company called Rubatex and called Neoprene and the original model of the high tech of today, was born at three levels suit.

Diving Dry Suit

            Diving dry suits are for diving in cold water settings and they come in a kind of style: full length arms and legs. The only difference between different brands of dry suits on the market are used in materials to the combination and placement of the slide to create.

            Dry suits keep the heat around the diver with a layer of warm air trapped in the clothing worn under the dry suit. As the diver Descends in water, the air is compressed in the costume, but the pressure may be offset by the use of a low-pressure hose to the air supply for divers.

As the diver ascends, the air was added to the mix are now broken down by the use of a deflation valve.

            The material used to make dry suits can either neoprene, crushed neoprene or some other type of lightweight fabric that is reinforced with a waterproof material such as vulcanized rubber.

 

Diving dry suits are the only way to go if you are in cold water (50 degrees or less).

  Their disadvantages are:

       * You are a maintenance problem
       * They are more cumbersome
       * Dry diving suits are expensive
       * There is a learning process for them

You do not have the ability to change them under water. If in any case that you have emptied the power source at the beginning, you will surely miss the opportunity to take photos precious that you add to your album.

PLACE in The Waterproof Housing

Water can not possibly enter the camera. It will only destroy the device safely. One thing you can do, the camera in a waterproof housing space. Buy one and read the manufacturer's instructions. Make sure the camera is aligned in the slot. Also, make sure that there will be leaks o, because if there was, the camera will be safe on the danger.

Secure It

One of the most important things you need to do is set the camera before diving. The water can swim, the camera, because this type of equipment is a little holder. This enabled the camera to go away from you and entangled with other devices. Use a power cable and set the camera to your belt or in a part of your wetsuit.

Good Position
 
As to take images or videos, take one thing you need to make sure you are in a good position to do so. You must be in an area where you are stable, so the results should be positioned smooth and clear. You must also ensure that your problems can be clearly seen. Lighting issues must be considered.

Tips For Choosing a Dive Watch

           Reliable, dependable, the clock is an important tool in any toolbox dive, figuratively. The selection of a suitable monitor, while a complicated process that can take up to a few key steps and priorities must be diluted .

1. Water-and corrosion-resistant cases. 
      Diving watches are universally built to withstand the pressure of the water to a certain manufacturer-specific assessment. It is also important to have a clock that has a pouch, wrist strap and face, designed to find the corrosive properties of most common chemicals in the oceans, lakes and rivers hold elected. Many watches are also designed to withstand the external pressure and magnetic effect of moderate amounts of stress.
2. Rotating Bezel. 
      A bezel allows a user clock, keep track of elapsed time keeping. The exterior of the telescope clock is ticking, so that users keep the clock to keep track of the passage of time, with no specific time when they remember to start the monitoring process. Many watches also come with self-locking panels, eliminating the possibility of inadvertent movement. The less you worry about diving, the more energy you have to spend to Staying Alive.

3. Press helium valve. 

Only an extremely deep dives possible concern, a helium release valve evacuation of helium-input clocks during technical dives or dives of 200-300 meters. Without this feature, watch for very deep dives in helium-rich environments often experience a break in the case, or a dial tone to explode.

4. Readability. 

What seems clear is decipherable in a shop of watches is often very different from what you see at 85 feet easily in muddy water. Quality diving watches come with a face and choose a colorful design and easy to understand, put together high-contrast colors.

5. Reserve indicator. 

Battery-powered diver watches, and even those who should come with a backup system to make dough, equipped to draw attention to some of the indicator for the diver on current performance levels. This is to avoid potentially dangerous situations or uncertainties associated with the reliability of shows.

6. Crystal Case. 

A diver's watch has a face quality of the design is very thick crystals. This is the result of additional pressure from outside, many diving watches will be on the course of normal use. Without this extra effort, many diving watches is an experience that is leaking, cracking or even complete collapse face, even when used at moderate levels deep. The case of the face should also avoid scratches and scratches to visibility problems and complications.

Scuba Diving Gear 2 (End)

       Well, This is the rest of the gear, there are :

• An underwater compass, is a very handy navigational tool and is a common piece of equipment for divers to carry. Compasses can be attached to gauge consoles, worn separately on the wrist, attached to the band of a watch or dive computer, and digital compasses are now even built into the latest dive computers.
• Snorkel, is a plastic tube that allows you to breathe while you're swimming on the surface. It is normally attached to the left side of the mask. It's a great way to conserve the air in your cylinder while swimming on the surface. Snorkels also come with such features as purge valves (to make it easier to clear any water inside) and splash guards (to make it hard for water to splash in the top).
• Cylinder, he dive cylinder is what you use to carry your compressed breathing gas (usually air). Dive cylinders are typically made out of aluminum or steel and come in various sizes with the most common size being 90 cubic feet / 12 liters. Breathing gas is compressed inside the cylinder at up to 3000psi/210bar.
• Regulator, is a what you use to breathe the air from the cylinder. The regulator is divided into two parts: First stage is the component that attaches to the cylinder and converts the pressurized air inside to what's called intermediate pressure (less pressure than in the tank but still higher than breathing pressure). The regulator usually supplies air to the Alternate Air Source and BCD (Buoyancy Control Device) in addition to the Second Stage Regulator. It will also have an SPG attached to it.Second parts is the component that you put in your mouth to breathe. It reduces the air coming from the first stage regulator to ambient pressure (the right pressure for you to breathe).
• Depth gauge, this gauge shows you how deep you are. Depth is measured in either feet or meters.
• Dive Computer, also tell you your depth and dive time but it is also common for dive computers to calculate no-decompression limits over multiple dives. Many newer dive computers will also track air consumption and temperature and some even have built-in electronic compasses. Dive computers are commonly found attached to gauge consoles or worn on the wrist like a watch and can now be found built into masks.
• Dive knifes, It is good practice to carry a dive knife or shears. Dive knives are not used as weapons, they're used to free yourself from entanglement, particularly from fishing line. Many divers carry more than one knife for added safety and it's advisable to wear one on the BCD and one strapped to a leg.
• Hood, If you're diving in cold water you're likely to wear a hood. A hood is a neoprene cap that you wear over your head to keep it warm and can be thought of as an extension of the wetsuit.
• Slate, There are many different types of slates, but the most common are fish slates and writing slates. A fish slate is a waterproof plastic sheet covered in pictures and names of fish (and other creatures) the diver is likely to see. A writing slate is a blank piece of plastic with a pencil attached by a cord and is used to communicate by writing underwater, taking notes, or drawing. Slates are normally attached to a D-Ring on the BCD.
• Submersible Pressure Gauge, (more commonly called SPG) is the gauge that tells you how much air you have left in your tank. Air pressure is measured in PSI or bar. Most SPGs have a section of the dial highlighted in red which shows you when you're getting low on air. 
• Weight System,  Most people need weights to sink in water. There are two common weight systems: Weight belt and Integrated weight, Weight belt is most commonly a nylon belt which has lead weights attached. It is secured with a quick release clip at the front which can be released rapidly and easily with one hand if needed. And Integrated weight or Weight Pocket is attached on BCD, These pockets are secured using Velcro or quick release clips which can be released as easily as a weight belt. Most divers find integrated weights much more comfortable than a weight belt. 
• Wetsuit, keep you warm while underwater. They are made from neoprene and designed to be worn snugly in order to allow little water to move against the diver's skin. They work by insulating the diver from the cold water. Wetsuits come in many sizes from one millimeter to seven millimeters or more, with the most common sizes being 3mm, 5mm, and 7mm. The most typical styles are: The Shortie style has short arms and legs and is typically worn in tropical water. A full one-piece suit that can, depending on thickness, be worn in cold, temperate, and warm water. This is a two piece wetsuit that overlaps to provide more warmth on the torso. The Farmer-John was previously quite popular but is now primarily used in cold water.

Scuba Diving Gear 1

    There's so many gear that we must know, when we do Scuba Diving. And for know, let's talk about Alternative air source, Buoyancy Control Device (BCD) , Booties, and Fins. The Gear are :

Scuba Diving Gear

• Alternative air source, is your backup second stage regulator. It works just the same as the primary second stage regulator and can be used in the unlikely event that your primary fails or your dive buddy needs to share air. It is usually a bright color such as fluorescent yellow or pink and is normally secured somewhere within the triangle between the chin and the bottom of the rib cages, normally on the right side.It also known as Octopus

•  A Buoyancy Control Device (or BCD for short) is the jacket that scuba divers wear. It serves a few basic functions: It contains an inflatable bladder which you can add or subtract air from, allowing you to change your buoyancy in the water, The dive cylinder is attached to the back of the BCD using a tank strap, It allows the diver to carry or attach all of their accessories using its inbuilt pockets and D-Rings .
• Booties, is also used to protect the feet, particularly when shore diving, and some divers find them more comfortable than full foot fins.
•  Fins, are long flat rubber or plastic extensions of your feet that allow you to swim with much greater ease and speed. The two primary varieties of fins are full-foot and open-heeled. Full-foot fins completely cover the foot like a shoe and are most commonly used in warm tropical water. Open-heeled fins have a strap across the back and are worn with booties to allow the feet more warmth and comfort. It also known as Flippers .
