How can I tell if Aqualung legend has ACD

[ianwhiteman]

I am looking at an aqualung legend that was dove once for a friend but the guy selling it knows nothing about scuba gear. Can anyone tell me how one would know if it has the ACD feature or doesnt so I can ask him to look?

Thanks in advance for the help!

Look at where you would normally expect to see the air filter, and if you see metal surrounded by a springed ring that would be pressed in by the valve, its acd!

Thanks for the help, I am not sure if this guy will even be able to figure that out but Ill try it. Was hoping it was written somewhere on the reg.

Perhaps you can send him a picture? So he could check it.

If he cant see in - like written bevore - if he can see only gray and not silver(filter), than it is the ACD-System.
