Cressi-sub SIGMA Snorkel
The SIGMA snorkel tube, without flexible joint, is securely mounted on
the mouthpiece holder with several grooves and O-rings:
this is a useful feature particularly during ascent with
self-breathing apparatus or when the snorkel is placed
in a BC jacket pocket. Other comfort enhancing
features of this Sigma snorkel, even for the most demanding
professional divers are:
- profiled guard
- elliptical tapered tube
- angled mouthpiece
- increased well for
better drainage
- larger internal elliptical valve for
improved drainage.
Cressi-sub’s low cost snorkel for
professional divers.
