The Achilles Heel of all second stages is a small
rubber valve seat. In standard designs, this seat is
pushed tight against a sharp edged orifice from the
day it leaves the factory, eventually making a deep
impression in the seat resulting in poor performance
and annoying leaks, not unlike that of an old leaky
faucet. That’s why sometimes your regulator is
fine when you put it away and it leaks the next
time you use it. Our orifice only contacts the seat
when pressurized. When not being used, the orifice
automatically retracts away from the seat just enough
to prevent damage during storage. This dramatically increases the service life and
maintains “like new” performance. (See additional post-dive care note pgs. 28-29.)
either overcompensate at the surface or do not provide adequate venturi at depth.
The AFC is a small blade (airfoil) inside the mouthpiece that changes position with
response to depth to maintain consistent, natural, effortless breathing at all depths.
The blade is attached to a depth sensing diaphragm that retracts it to gradually boost
the venturi the deeper you go. No dials to turn or buttons to push, the regulator
“tunes itself as you dive”.
