Surface Air Valve Mask Bag
Supply Hose
The Surface Air Valve allows the
diver to breathe ambient air at
the surface, thus conserving the
available gas in their cylinder. The
SAV is available at time of mask
purchase or can be easily installed
later.
The OTS Mask Bag, featured on
page 24, is a great way to store
your Mantis Full-Face Mask.
OTS carries a large supply of
standard low-pressure 2nd
stage supply hoses in a variety of
lengths.
Mantis Full-Face Mask
The Mantis is a low volume full-face mask (FFM)
manufactured with a one-piece, non-ridged silicone skirt
available in either a black or clear configuration. The
Mantis FFM is an ideal piece of equipment designed to
fit the needs of today’s demanding sport and technical
divers. Its low-volume skirt is designed to fit a wide range
of face sizes.
The Mantis FFM is designed to be used with your
existing second stage regulator, accounting for its more
economical price. Simply remove the second stage bite
mouthpiece, insert it into the FFM, and attach with a new
zip-tie. The dual tempered, anti-fog lenses of the Mantis
FFM offer exceptional visibility and clarity. The design of
the Mantis FFM allows for traditional, and more familiar,
Valsalva-type ear equalization similar to a standard diving
mask. The Mantis FFM incorporates a five-strap (spider
type) system that securely attaches the mask to the
diver’s head and incorporates quick release buckles at
its base.
The Mantis FFM is designed with dual accessory ports
for use with OTS underwater communications or an
alternate air source.
Available in Black or
Clear skirts.
