The job of the scuba regulator is to supply air to the diver at ambient pressure. The first stage of a scuba regulator attaches to the tank and reduces the pressure of the air in the tank to ambient pressure plus a preset intermediate pressure. The air is then sent down the hose to the second stage. 

Features to consider when selecting a scuba regulator: Balanced vs. Unbalanced - a balanced regulator breathes the same at all depths while an unbalanced regulator is increasingly difficult to draw air from as you go deeper. All balanced regulators compensate for depth by equalizing the pressure on both sides of the air valve to the pressure of the surrounding water. The balanced regulator air valve essentially “floats” in an pressure chamber.

Most new scuba regulators provide two high pressure ports for pressure gauges and four low pressure ports for second stages, LP inflator hoses or dry suit hoses. Second stages offer external adjustments that can be made by the diver while diving to vary the performance of the regulator. The venturri assist is a two position adjustment that creates a venturri effect to optimize breathing performance and help prevent free flows at the surface. Another type of adjustment is the adjustable air flow knob or dial. This adjustment alters the flow rate to compensate for depth changes.

Diaphragm vs. Piston - refers to the mechanism that opens and closes the air valve in your first stage. Each represents a different design style. While neither style is necessarily better than the other, some prefer diaphragm-style regulators for their minimal moving parts.

Metal: Today's scuba regulators come in a variety of metal configurations. The classic first stage construction is solid brass with a chrome covering. Now we have the entrance of the all new titanium models that offer less weight and 100% corrosion resistance. Second stages also come in a variety of metals and plastics. Brass and chrome second stages, Tri-metal, Titanium, Plastic, and Plastic-with Metal inserts for re-hydration of the air.
