If these people are adventurous and have not they spend their money, lucky you, because I assure you that this list will make your dreams come true.
1. Base jumping in the New River Gorge Bridge, USA
If you come to Fayette County on the third Saturday of October, you can enjoy the ‘Bridge Day’, this day will offer demonstrations of rappelling, climbing and BASE jumping.
2. Bungee jumping at Victoria Falls, Zimbabwe
Among the border between Zimbabwe and Zambia are the Victoria Falls. This place is ideal setting for bungee-jumping, in fact, is considered one of the highest waterfalls in the world.
3. Skydiving over Lake Taupo, New Zealand
Snow-capped volcanoes and stunning scenery in brochures invite everyone to visit this site. Lake Taupo is renowned as one of the best places to skydiving that includes more than a minute in freefall. Read the rest of this entry »
You can not breathe directly from the tanks because the water may damage our lungs. Therefore, the cylinder has a regulator. Diving Regulators do two things: reduce the pressure of the tank to a level safe for you to breathe, and we manage the air as claimed. To do these tasks, regulators have two parts:
* First part – This part is directly connected to the cylinder. What it does is reduce the tank pressure to lower it to an intermediate pressure.
* Second part – is connected to the first part through a hose. Reduce the pressure of the intermediate pressure to ambient water pressure. It also provides air, on an ongoing basis (emergency mode) or only when you inhale (as normal).
The first part consists of high-pressure chambers and intermediate pressure, separated by a combination of valve-diaphragm or a piston, which is in contact with water pressure. The high-pressure chamber receives air directly from the cylinder, while the intermediate pressure chamber is in contact with the water pressure through the diaphragm or piston. The system works as follows:
* Inhale, and thus reduce the pressure in the intermediate pressure chamber below the surrounding water pressure.
* The water pressure pushes inward, opening the valve or piston.
* The open valve connects the high pressure chamber with the intermediate pressure chamber.
* The air flows from high pressure chamber into the intermediate pressure chamber, increasing the pressure in the intermediate pressure chamber.
* When the pressure in the intermediate pressure chamber equals the pressure in the surrounding water, or piston valve closes.
* The process is repeated when you return to inhale.
The first part usually have multiple entries with hoses leading to the second part, as well as other devices such as a second additional part, a flotation device, etc. The second part of the regulator is:
* A plastic chamber with a rubber diaphragm in contact with the surrounding water pressure.
* A purge button.
* An internal valve that is connected to a movable handle.
* A flush valve.
* A nozzle.
The second part is connected by a hose to the intermediate pressure chamber of the first part. It works as follows:
* Inhale, and therefore lower the pressure in the second part to lower levels of water pressure.
* The water pressure presses in the membrane of the diaphragm and pull the lever.
* The movement of the lever opens the valve interior. This allows air to flow in the second half from the first part, and your lungs through the mouthpiece.
* When you exhale, the pressure in the second part of the water pressure exceeds the environment and pushes out the membrane.
* The membrane is displaced, allowing the lever returns to its normal position and thereby closing the internal valve.
* The increased pressure of the second valve opens allowing exhaled air to leave the second half.
* When you return to inhale, the valve closes and the process repeats.
The regulator must be cleaned with fresh water after each dive to remove salt water and elements that could impede the movement of multiple valves and membranes. It also prevents corrosion of parts. Regulators submarines should be reviewed at least once a year. As the regulator of the most important parts of diving equipment, many divers choose to purchase their own regulators, rather than renting the equipment, so you can rely on their good performance.
The last parts of equipment that helps us breathe, are accessories that contain emergency supplies or additional air. One of the most notable are the pony tanks, which are small cylinders that are hooked to the large air cylinder and have their own regulators. Provide enough oxygen in the event of an emergency situation, such as the rise of a very deep. Another device is a typical tube or snorkel, which is attached to the mask and breathing that allows us to swim on the surface upside down.
With it you can explore in a broader, deeper
ity diving in apnea and used supplies allow.
The equipment used here is the Heavy Equipment consists of:
* Compressed air bottle
The variety, quality and price of each of these components and accessories that enhance diving are very large so I recommend that you advise well before making the investment.
Little by little we’ll tell you what function each piece of heavy equipment and give you tips that will prove very useful.
Tenerife is the largest of the Canary archipelago. For beach lovers and sports and leisure opportunities, a priority, because it has no fewer than 140 beaches. Choose one or the other depends on personal taste. Canary beaches are wild, some more than others, but brave. Precisely why they are sought by surfers and sailors hair. But bathing in them is another thing. For example, in Candelaria beach, as in many others, it is advisable not to stray too far from the shore at least if you’re not a crack of swimming.
Scuba diving in Tenerife, is a joy. Seabed are havens dream know that you can see reflected a reality that seems fantasy. Corals in clear waters in which many different species of fish, crustaceans and marine inhabitants that complete the feeling of being unreal. One of the most exotic or bizarre marine inhabitants is the seahorse. Propelled swimmer can measure about 30 cm, is a charming creature that can display a wide variety of colors from ivory white to red to yellow and dark brown or black and often mottled. The cartoons have been lovely, but seeing it in reality is downright amazing. Read the rest of this entry »
