Does anyone know if Scubapro S600 comes with purge key?

Does the S600 second stage come with a purge key from the factory? Basically do you have to keep the purge button pressed in while in storage? A friend of mine has one and is using a quarter wedged in there and I could not find any purge depressor anywhere. Thanks

Because it does not need one. The balance chamber design on the G500/S600/G250HP Allows the LP seat to automatically pull away from the orifice when not under pressure. If you shake the reg when not under pressure, you can hear the lever rattle indivcating the seat is not in contact with the orifice. I think Scubapro calls it the "anti-engraving feature".
