Regulators.. Mount Up!

Posted on Posted in Equpment, Regulator

There are essentially two different types of assemblies when referring to regulators, the piston and the diaphragm regulators. They come in a variety of flavors, and both have their place.

There are also unbalanced, balanced, and overbalanced setups that must be taken into consideration.

  • Unbalanced setups supply a slightly lower intermediate pressure as the tank empties
  • Balanced setups supply the same intermediate pressure regardless of tank pressure
  • Overbalanced setups allow more air out the first stage at depth giving you better breathing performance, regardless of depth. Like balanced regulators, overbalanced regulators will not decrease in performance as your tank pressure decreases but will give you excellent performance pretty much up the moment your tank runs out.

So what’s the deal with regulators. How do you know which one is the right fit for you? We have a number of options that will work well for any situation.

We primarily sell Aqua Lung regulators since they:

  • Are built for new and experienced divers and a range of diving conditions
  • Qualify for free parts for life!
  • Use parts that are common to other Aqua Lung models for easier servicing
  • All regulators use a Comfortable-Bite mouthpiece that greatly reduce jaw fatigue
If you are looking to build a rental inventory these regs are great. They are a piston unbalanced regulator that offers a simple robust design with solid performance at a low cost.
For a new diver on a budget, we would recommend the Titan. The Titan is an upgrade to the Calypso. It uses a balanced diaphragm and is rugged and comfortable. It offers excellent performance and easy maintenance at an affordable price. Side openings prevent free flow when facing into currents or riding a scooter.  
The Core is an affordable pneumatically-balanced diaphragm regulator that rates as superior on the ANSTI breathing machine. The core also seals out water with Aqua Lung’s auto-closure device (ACD). A heat exchanger comes standard which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.  
The Legend is is an overbalanced diaphragm regulator that comes with the auto closure device (ACD). It comes standard with the venturi switch to prevent freeflow at the surface and when in a divers mouth. It also comes with a Heat exchanger which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water. It features an ergonomic exhaust that channels the exhaust bubbles out of your field of vision. The design also contributes to a reduction in exhalation effort  
The Legend LX  is a high performance overbalanced diaphragm regulator that comes with the auto closure device (ACD). The real upgrade to this regulator is the Master Breathing System (MBS). The MBS controls two functions at one time. It controls the direction of air, which alters the venturi effect, as well as changes the opening effort. One control – two functions, it doesn’t get easier. A Heat exchanger which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water also comes standard with this regulator.  
Along with the Legend LX is the Legend LX Twilight. This regulator offers the same features as the LX, but was specifically designed with a smaller mouthpiece with women in mind.
