Cressi

CRESSI Octopus Compact for Scuba Diving Regulators - Compact, Reliable, Light and Comfortable - Made in Italy

Octopus made in ultra simplified single-hull in ABS + elastomer of really compact size (2.36 in | 6 cm in diameter), extremely light (5.15 oz | 145 g). Its mechanism and development are planned to obtain the minimum number of components and great strength
It's a smart shopping option because of its combination of features - reliability - price - maintenance cost. It's suitable for maximum reliability uses and also as a travel regulator due to its lightness.
The specific calibration of the inhalation mechanism changes slightly the personality on air output, rewarding an abundant flow without the need to exploit Venturi effect, beyond the exquisite touch and sensitivity of these kinds of regulators.
Exhalation effort reduced without the need to minimize the diaphragm thickness. The restraint system design of the diaphragm guides the flow 100% channelled towards the nozzles of the exhaust tee, that helps to guide bubbles far from the visual field.
Practically integral purge pusher, bigger between 80 and 400% than any other regulator in the market to facilitate purge manoeuvre, especially to inexperienced divers.
Reduced usage aging due to the finish of the casing, as a result of applying in the mold a new technology that obtains a nuanced appearance made of a microtexture of rounded profiles.
Yellow jacketed hose extremely light and flexible weight: 153 gr - 5.4 oz.
