For Scuba Diving Cartagena Is Worth Visiting

By Mark Perry


Scuba diving has been around since the 20th century. This activity is linked closely to the history line of the scuba equipment. It began by the development of two very important underwater apparatuses. The two were the closed circuit apparatus and the open circuit apparatus. In the open circuit apparatus the diver exhales the gas directly into water. The introduction of the demand regulator greatly boosted the development of this apparatus. When one needs Scuba Diving Cartagena offers the perfect location to visit.

Later, this was followed by the development of a diving suit. The suit enables the diver to be supplied with air as required. This can be done by just adjusting air flow from the tank according to the breathing pressure requirements of the diver. The air was supplied from the surface because the design of the cylinder back then could not withstand the high underwater pressures.

Air cylinders were developed in the early nineties. This enabled divers freedom to move around and explore the underwater. Nowadays the open circuit consists of a cylinder that has compressed air which the diver carries on their back. The compressed air is attached to some pressure regulator, which the diver can adjust manually.

This design has 2 gauges. One is for supply pressure while the other is for tank pressure. Air is constantly supplied through the mouth piece then ejected via a short exhaust hose. The pipe has a valve for regulating the air. Compared to previous designs the current design is much better, although it still needs to undergo further improvements.

According to studies inventors are on the search of a way they can make scale down the whole system. The aim of this idea is to increase the valuable time of underwater breathing apparatus. Closed circuit and the open circuit apparatus were developed at around the same time. In this system the carbon dioxide gas the diver exhales is allowed to recirculate back after being filtered with unused oxygen.

Research indicate that people only use a tiny portion of oxygen when they are underwater. The recirculation reduces oxygen. The system has a rebreather which recycles the breathing gas that is exhaled while concurrently refilling it from supply. This is to ensure that air is in constant supply due to depletion. The first design was comprised of rubber mask that was attached to some breathing bag.

The content of the bag are 60 percent oxygen which is supplied from a cooper tank and carbon (IV) Oxide which is scrubbed by a rope yarn dipped in a caustic solution. However, this system is undergoing further development. Today, the model being used is quite improved and is capable of travelling thousands of feet deep down the ocean. Also, it holds large amounts of oxygen.

People engage in this activity for a number of reasons. There are those who do it for sport while others do it as a profession. Those who do it for sport usually crave the thrill it provides when they engage in deep sea diving or cave diving. Those who take it as a profession are employed to partake in underwater tasks. The military also uses it for infiltration and direct combat.
