Questions and Answers for Aqua Lung Legend Regulator:

  • Evan:

    Im thinking of buying a Legend. My current reg has a swivel connector at the reg and I have found it to be quite nice when the reg is putting more pressure on one side of my mouth. I dont see a swivel on the Legend. Is there a mod for this? I understand that this reg comes with the flex hose but is there benefit to adding the swivel connector mod if it exists? Thanks!

    Bob  (Certified Scuba Instructor at

    The flex hose will do the same thing as the swivel without adding an extra piece to the equation. You could, if you wanted, add the aftermarket 2nd stage swivel to it, but over time you''ll find you don''t need both and the flex hose offers more freedom of movement.

  • Ed:

    Does the legend come with the ACD? If I get the reg from you can I have my local dive shop service it ,or do I have to send it back to you? What would the turn around time be?

    Darrick  (Certified Scuba Instructor at

    Hello Ed, yes this has the ACD, also yes if you buy this from us any authorized dealer for Aqua Lung in the world would be able to service this as long as you register this with the manufacture. You can also send this to us for service if you like. Our normal turn around time is 2-4 weeks but that also depends on the time of year.

  • Nathan:

    How many high and low pressure ports does it have

    Darrick  (Certified Scuba Instructor at

    Hello Nathan, this has 2 high pressure and 4 low pressure ports.

  • david:

    when ordering a regulator, does that come with a alternate air source. that is a emergency secondary air regulator for a buddy to use that is hooked to your bcd

    Darrick  (Certified Scuba Instructor at

    Hello David, no the alt air source you are speaking for is an added cost. The 1st stage and the primary regulator and attaching hose is the only thing that comes with this unit.

  • david:

    how do I look up alternate air regulator? trying to make a octopus with bcd, alternate air, regulator and guages

    Darrick  (Certified Scuba Instructor at

    Hello David, you would attach the low pressure hose into one of the low pressure ports. Then the computer/gauge hose would attach into the high pressure port.

  • Izzy:

    Hi, im eleven years old a certified diver, just want to find out the difference between the aqualung legend LX, LUX and the Supreme , just thinking of asking my dad for a new reg,

    Arthur  (Certified Scuba Instructor at

    Hello, the main difference is that the LUX has the •Auto-Closure Device (ACD) keeps corrosive water out by automatically closing when removed from the cylinder valve - Preventing the internal lubrication from being washed out.

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.

The Legend shares the same features and performance as the Legend LUX and Legend LX with one notable exception. Instead of the MBS dual control valve, the Legend offers a venturi switch.
The venturi switch helps prevent freeflow at the surface and when the regulator is out of the diver’s mouth
The opening effort is preset in a fixed position so the diver doesn’t have to worry about adjusting the regulator during the dive
