Aqualung Core Regulator

The CORE regulator’s amazing breathing, which is rated as "superior" on the ANSTI breathing machine, coupled with its generous features, at an attractive mid-range price, provides the best value of any regulator offered today. The CORE comes standard with Aqua Lung’s unique, patented, auto-closure device (ACD) which seals water out.


  • Auto Closure Device (ACD) - keeps corrosive water out of the first stage inlet by automatically closing as the CORE is removed from the cylinder valve, this prevents internal lubrication from washing away.
  • Safer for elevated percentages of oxygen
  • The balanced diaphragm first stage provides superior, consistent performance
  • The pneumatically-balanced second stage results in smooth, easy breathing
  • The T-shape of the first stage optimizes the location of the 4 MP ports and 2 HP ports
  • Uses parts that are common to other Aqua Lung models for easier servicing
  • The easy-to-grip venturi lever prevents unwanted freeflow at the surface while giving a performance boost at depth
  • A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water
  • Compatible with EAN 40 new, out of the box
  • Equipped with Aqua Lung’s patented Comfo-bite mouthpiece along with a reusable mouthpiece clamp


The Aqualung line of quality regulators  come with 1.)  limited lifetime warranty that will cover the original owner of the product against defects in parts or workmanship for the lifetime of the regulator as long as it is purchased from an authorized dealer (OnlineScuba is an authorized dealer) 2.) regulators are serviced annually by an authorized dealer.

Aqualung Core Yoke
I bought this for my daughter, who is an infrequent diver who I didn't want to spend tons of money on, but still wanted a quality product. This is a perfect answer to anyone who dives infrequently (2-3 times a year) and isn't in a position to spend thousands of dollars on equipment. Since she will likely never dive in very cold water, I opted for the basic Core Yoke. It arrived very well boxed and with sufficient instructions to attach the pressure/depth gauge I also bought. Once in the water, it worked very well for her. She had not complaints and her air was consistently better than my own. I highly recommend this product. I wish I would have seen this before spending my fortune on a regulator!
