The VUELONG Scuba Diving Regulator is a second stage regulator that’s big on quality yet low on price. A second stage regulator is the part that you put in your mouth. This diving piece comes in either orange or yellow. If you’re wondering how it works, an intermediate pressure hose is used to carry air from the first stage regulator to the second stage, which is held in the diver’s mouth. You can’t dive without a regulator, and this one will ensure maximum comfort and enjoyment.
