Regulators
one of the lightest intake resistance values in the industry compared with products
from other companies.
New mouthpiece
The new mouthpiece, developed on the basis of ergonomic engineering, further
enhances the comfort of bite, fit, and stability. Even with a light bite, a high level of
stability is achieved, so there is no fatigue from long periods of usage.
Venturi Adjustment Lever (RS-460, 680, 790, 811, 812, SS-60, 80)
The addition of a venturi adjustment lever allows the regulator to power assist the
diver when underwater utilizing the natural venture effect. The diver can also adjust
the lever to prevent free flow such as on a surface swim.
Swivel joint (RS-340, 350, 670, 680)
For optimum performance and comfort, a swivel joint is fitted between the second
stage and the joint section of the low pressure hose. The swivel joint allows flexibility
of the hose for eliminate hose tension at the mouthpiece for a more natural and com-
fortable bite.
"Air Refresher" filter (RS-350)
There are two types of high tech filter built into the second stage. An active carbon
filter cleans the air and absorbs smells, while a metal fiber filer eliminates particles
as small as 100 microns.This makes sure that the cleanest and safest air is supplied
to the diver.
S.E.A. -Sequential Exhaust Assist [PAT.P.] (RS-680)
The Sequential Exhaust Assist (S.E.A.) is an auxiliary exhaust valve, located on top
of the S-80 elliptical case to decrease primary exhaustion resistance.
