Legendary performance from Aqua Lung, a tradition for 60 years.
The Aqua Lung Legend Supreme ACD Diving Regulator incorporates a proprietary over-balanced diaphragm first stage design coupled with a high performance balanced second stage.
The over-balanced first stage achieves unprecedented performance by increasing your air supply the deeper you go.
The balanced adjustable second stage reduces breathing resistance to near zero with a lightweight balanced valve seat designed to respond instantaneously to the slightest inhalation.
*ACD - AUTO CLOSURE DEVICE
This system automatically protects your first stage from the environment as soon as it has been disconnected from the cylinder valve.
