I got two used Aqualung Powerline Gen 2 inflator systems. These systems have been looked through by a technician and they both worked great. They are a perfect back up for any of the Aqualung BCD's that have this system on them. If you ever have a problem on your system all you have to do is unscrew the present one and screw this back up system on. Their picture are the first two pieces on the left side of this picture.
