The Rev 2 is pretty old now although, I believe, it is still supported.
They’re supposed to have a major service, returned to the factory, every five years. I think there’s a US based company that will do the servicing.
With all rebreathers you need to get unit specific training before you dive them.
That appears to be a good price. But…. Be prepared to spend money on the unit as there’s bound to be issues. Cheap rebreathers can be expensive.
Some questions:
- Can it hold a negative pressure test?
- How old are the cells?
- State of the wing?
- State of the lungs?
- Cylinders in test?
- Spares?
You’ll need to find a Revo-specialist trainer for your CCR course.
