Aqua Lung LEGEND SUPREME ACD Regulator



The Legend Supreme is specially designed to withstand the cold with the same high performance and breathing comfort characteristics of the Legend LUX but without the pink gold finish. The Legend Supreme is equipped with a lip protector to keep the lips warm and offers a new venturi flap.

Auto Closure Device (ACD) As soon as it is disconnected from the valve of the block, the 1st stage is protected from ambient

o The performance of the regulator is preserved over time
o Lubrication of internal parts is preserved
  • T-top membrane overcompensated for superior depth performance
  • 2 high pressure outputs and 4 medium pressure outputs perfectly positioned and symmetrical ensuring perfect orientation of the hoses
  • Dry chamber to protect the spring, water does not enter and prevents the formation of ice and the pollution of the components during dives in loaded waters
  • Available in saddle or DIN version

Second Stage:

  • Compensated mechanism offering very great inspiratory flexibility in all situations
  • The venturi flap and its easy-to-grasp control lever makes it possible to quickly and easily stop continuous flows
  • Comfo-Bite ™ mouthpiece minimizes maxillary fatigue for optimum fly comfort
  • The heat exchanger (patented) which includes the seat / valve mechanism dissipates the cold of the trigger while heating the internal mechanism
  • The geometry of the lateral openings improves the stability of the regulator during a rapid descent or against the current
  • Shapes of exhalation mustache improves expiratory effort and frees the field of view
  • Flexible braided Aqua Flex of 730mm length. It is very soft and extremely light, it improves the comfort in the mouth by limiting the effect of tugging of the mouthpiece

In addition to the dry chamber and heat exchanger on the second floor, which is found on other Legend models and provides excellent resistance to icing, this Supreme version is:

  • Specially adjusted to withstand icing
  • Equipped with a lip cover on the second floor to keep the lips warm
