Up for sale is 1 Aqualung Legend Supreme First Stage ACD regulator. This is Aqualungs finest first stage that is paired with the Legend Supreme. It is ACD, fully and environmentally sealed, rated for cold water and the ACD feature keeps out contaminents from the first stage. This regulator is brand new, never used, never wet, I inquired from a lot sale from a closing dive shop and this is the last one. These are in high demand and are an excellent regulator for the beginner or the advanced diver. I personally use it with my Legend Supreme and it is flawless. The ACD feature also makes the first stage super clean, rarely, if ever, needing service. I am asking $150 or best offer plus shipping and paypal 3.8%. PM me with any questions/inquiries you may have.
