Scuba regulator
When you go scuba diving, you are able to breath underwater by using air that is stored in a tank. Since your lungs are unable to handle the air directly, you must invest in a scuba regulator that funnels air to you in a controlled manner. A regulator usually functions in two stages. The first stage involves the regulator reducing the pressure of the air. The second stage is when the air is actually delivered, either by the diver's actual inhalation or by a valve the diver controls manually.
While you can purchase a scuba regulator that provides either stage one or stage two, most regulators nowadays are designed to handle both stages.
The Scubapro MK25/S550 Regulator can handle both the first and second stage air compression and delivery systems. This regulator features advanced first stage air compression provided by using five ports that use a swivel system. These ports are designed to handle extremely high pressure. The mouthpiece, which is often a source of stress for divers since you have to hold it the entire time you are diving, includes a safegrip feature that enables you to hold it with your hand. The ergonomic design of the mouthpiece should also provide less stress on your jaw. For the second stage, the regulator includes a control to allow you to control the level of air that you need.
Another regulator that can handle both first and second stages is the AquaLung Legend LX Regulator. Maintaining your regulator is important to ensure your scuba regulator works when you need it. The Legend LX is designed to make this job easier. The chamber contains a seal that prevents debris and water from entering the system. This regulator also allows the diver to control the air flow.
The Dacor Eagle Regulator is a popular regulator among scuba divers. This regulator is designed to eliminate the stress on your jaw when holding the regulator mouthpiece in your mouth. Dacor is a recognized manufacturer of quality scuba diving equipment.
