Rating: Great Regs
Reviewer: Max Jaskiw  -  View all my reviews
I dont care much for the design of the first stage, but thats merely a personal issue. Its obviously functional and delivers gases at easy, adjustable flows. I dont notice much of a difference from the MAres regs I had been using for six years prior, but Im sure its an upgrade

  • Olivier:

    Hi, Does this regulator have the Auto closure device (ACD). I see it mentioned on the aqualung website, but not on yours? thanks, -O

    Darrick  (Certified Scuba Instructor at

    Hello Olivier, yes this regulator does come with the ACD.

  • Andrew:

    Is this an environmentally seal first stage that can be used in cold water? Is this the same first stage as the Legend LX Supreme?

    Bill  (Certified Scuba Instructor at

    This is a sealed 1st stage, if you are using the regulator in water where there is ice floating on the surface, the Supreme is a better choice.

  • Stephen:

    For the closest shop to your location you''ll need to contact the manufacturer directly. They can tell you where to go for service.

Discover the new Legend

The new line of Legend regulators crafts the future with innovative technology and sleek cosmetic appeal. The new Legends are smaller and lighter making for a more comfortable dive. Whether you are jet setting to an exotic location or diving your local spot, the Legend will give you the confidence to dive like a pro and look like a rock star.

Be a Leader. Be an Icon. Be a Legend.

If you want the same high performance features and ease of breathing as the Legend LUX but without the pink gold finish, you will find it with the Legend LX. Like the Legend LUX, the Legend LX features the Master Breathing System (MBS) .

The MBS is a new, simple and effective way to adjust the breathing performance of your Legend LX. 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.
