REGULATORS Your regulator is your
most important piece of SCUBA equipment. This is your life support piece
of equipment. Safety, Simplicity, Reliability & a Name You Can Trust. Due
to the large selection of Regulators available, we have broken them into
separate pages by brand. Click on the below links to view the quality
equipment we offer you. The Mares link will take you to our sister dive site Diver Emporium where you will find the mares and all our other products. The regulators job is to supply air to the diver at ambient pressure. The first stage of a 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 downstream via the hose to the second stage. Features to consider when selecting a 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 and as the air supply in the tank is reduced. 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 ambient pressure chamber. The unbalanced regulator relies on tank pressure and volume to deliver air to the diver. Most regulators provide one or two high pressure ports for pressure gauges and three or 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. Some of the better regulators use real Gem stones in the high pressure seats vs some use extra parts to get the same air flow rates. Metal: Today's 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. USED REGULATORS Your regulator is your life support piece of equipment. While all regulators we offer here meet Government standards of safety this is the piece of equipment we do not recommend trying to save money on. Don't think you can buy a used regulator to save money. You may end up costing your health for a few dollars saving. If buying used buy from a reputable dive operator that has authority to give you the factory warranty. We sell our used rental regulators every year to keep the newest and best in our shop. If you would be interested in a factory warranted and benched prepared used reg set give us a call.
