US Divers Calypso aqua lung regulator BLACK FACE LIKE USED BY HANNES KELLER!!

This is a very rare early US Divers aqua lung regulator in barn fresh condition. It is in ok condition and it the more rare early Black label version. WE hooked the reg up to a tank and dived it in the pool. That being said it should be serviced before use underwater of course. It needs some elbow grease and a rebuild before you should try to use it. This is the same regulator that Voit sold as the 40 Fathom. This one came to us barn fresh and has all the dirt and grim on it. We have not cleaned it up and we have priced it that way. We are still amazed that the reg works and breathed pretty darn well in the pool to boot!

This is the very same second stage that Hannes Keller used in his record dive!
