Here pictures of two more Scubapro skeleton regulators models.
The First stage is a Scubapro MK25AF Yoke Type
The Second Stage is a Scubapro Balanced Adjustable (BA)
It is a very reliable model which was discontinued just a few years back.
The reliable and robust Metal-Housing Design was reintroduced in 2009 with the new A700.
