Deep-sea diving for longer period will not be possible without the scuba regulators. This is an important scuba diving gear that a diver should be carrying with when staying underwater for longer hours. Together with the scuba tank, this makes diving and breathing in a depth of a few meters or more below water surface possible for a scuba diver.

A regulator is a typical device used to control and monitor the pressure of gas inside a cylinder. Scuba regulator has a specialized function than a typical tank regulator. It functions as a balanced medium for a diver to breathe underwater by minimizing the air pressure from the scuba tank to ambient pressure. It normally consists of two stages for functioning. Firstly, the regulator is affixed to a scuba tank through an A-clamp which is fastened by a yoke screw. A variation exists in the material that attaches the regulator to the scuba tank. In Europe, a DIN connector is slowly replacing the use of A-clamp and yoke screw in joining the regulator and scuba tank.

The mechanisms in regulating pressure may differ on the type of monitoring pressure changes. A piston-type regulator supplies a better performance when used in very deep waters. The maintenance of this type is regularly required to prevent the event of corroding the regulator especially that some internal scuba regulator parts are exposed to salty and contaminated water. The use of this regulator only limits to clean waters.

A diaphragm-type first stage regulator has the complexity in design and components than the piston-type. On the contrary, it is more advantageous to use when the durability calibration comes in. It does not corrode and it is good to be used in dirty and muddy waters.

Both types of first-stage regulator function as the gas-releaser and pressure-converter when the diver needs the correct amount of pressure for breathing. However, the complexity of the diaphragm regulator infers its cost to acquire than the piston-type regulator.

The second stage requires a device that will regulate the flow of gas by manipulating an on and off switch at the tank. A device for this stage may be manual or automatically operated demand valve.

Several types of scuba diving regulators are invented to fit the needs of scuba divers for inhaling and exhaling under water. Some are automatically operated and digitally designed to increase the likelihood of usability, convenience and of course the technology in marine products.

The materials in the fabrication of scuba regulator should be durable and non-corrosive to last for a long time. The usual metals for scuba regulator are titanium, stainless steel and brass. The titanium is a more durable material for scuba regulator device for the fact that it is a non-corrosive and hard metal. However, it is more expensive than the brass or stainless metals.

Scuba regulator is costly to acquire. The complexity to manufacture, type of materials used and the demand for the product are common factors of this high-value scuba item.

Scuba regulator is a life-saving device in scuba diving. Professional scuba divers have to be certain that all scuba diving equipments are fit to use especially the scuba regulator. The scuba regulator has the characteristic of providing information regarding the amount of pressure that the scuba tank is filling up inside. The regulator also has the function of providing emergency warning to the scuba diver when a gas tank is emptying.

To maintain the functionality of the scuba regulator, maintenance of the scuba regulator is imperatively required. Another way is to repair the scuba regulator when a doubt arises on its function.

Calibration of scuba regulator is important to maintain the usability of the item. This helps in ensuring the diver of the safety in scuba diving. Likewise, the result will bring an alarm on the user for the necessary measures he has to make to bring the scuba regulator functional again.
