no no this is a back worn rebreather it was first made in 1964 ,,the 57 does not mean the year....
As this seems to be an o2 rig - 20 meters is definetely out of range, by miles.
Max depth i would see at 6 meters.
What is the exeptional exposure of navy divers on 02 Rebreather's ? I think it is 10 meters for these guys,
so make sure you know what you are doing, think of an o2 monitoring as a pure o2 rig will kill you with depth.
