The sea is very quiet and can be very relaxing. Sand and sun not only make it easy, it goes beyond surfing to a pale blue sea. However, without self-sufficiency scuba diving or scuba diving, it is impossible to adventure in the ocean.

Today, scuba diving does not include heavy metal suits, but it includes cylinders and air hoses and offers excellent underwater activities for divers. However, this type of underwater exploration was not discovered until around the 18th century when the early diving history occurred. In 1771, a British man named John Smeaton invented the first air pump. It was connected to an air filled diving bucket which will become a gasoline tank today. Just one year later, a French man named Sieur Freminet invented the "breathing" device. The device recovers expiration entering the trough. Although this device paved the way for inventors to improve, Freminet died of hypoxia just 20 minutes after using the device. Another British inventor, William James invented a metal helmet that frequently appears in museums. It consists of a belt with a long tube that brings air to the helmet. This unit can only be used for diving for 7 minutes. However, until 1939, when the American physician Christian Lambertson made a military device, the term scuba was not used. It is used during the war and is the codename SCUBA. His equipment failed when the divers walked deep and they died of the wrong mixture. Finally, in 1943, Emil Gagny and Jacques Chouau invented an adjusting device that automatically changes the suit air pressure. If the regulator is connected to two metal cylinders, this provides a way for modern diving suits, as can be seen today.

Today, scuba diving is a term well-known to everyone. There are many reasons for people to diving.

Many people think that scuba diving is just swimming in water, but in reality it is a very exciting, dangerous and potentially lethal sports and activity. There are various types of scuba diving, from leisure to sports, professional diving. Scuba diving not only swims underwater, but also diving requires certification using technical equipment, scuba diving has many risks. - Scuba diving is a sport that allows you to get lost in the beauty of the underwater world and escape from gravity in a short time. Walk along the forest of algae, swim with stylish and noble sharks. You can find luck in the Duke of Spain or you can lose yourself to the beauty of the underwater kingdom. Some may say that diving is an extreme sport and it is dangerous for brutal hooligans. Although there are few risks, scuba diving is a safe and enjoyable hobby.

Scuba diving is one of the fastest growing extreme sports in the world today. This is underwater diving where divers use self-contained underwater breathing. When diving, the scuba diving device is completely independent from the supply surface of breathing water underwater. Scuba pilot is fully equipped with equipment such as gas cylinder, umbilical cord cable, gas conditioning equipment. Gas is usually compressed air, which helps the diver comfortably breathe in the water. In the cylinder, the gas is in a high pressure state, and the gas is supplied to the actuator via the regulator.

Scuba diving is a model of underwater diving, the diver uses an independent underwater mask (diving) to breathe in the water completely independently from the water surface. The scuba diver carries its own breathing gas source, usually compressed air. It has more independence and freedom of movement than the diver provided to the Earth's surface, and it is longer underwater durability than underwater diver. An open diving system consists of one or more underwater gas cylinders containing high pressure breathing gas which releases respiratory gas into the environment during exhalation and is supplied to the diver through a regulator. They can contain additional cylinders for extent expansion, vacuum gases or emergency breathing gases. Collect breath with closed or semi-closed rebreather diving system
