it is a full-face mask ( FFM ) and it is designed to give the user the opportunity to breathe easily.
Obviously, it’s not the first of its type. In fact we could say that Cressi’s Medusa mask was the first FFM but it didn’t separate the breathing chamber from the vision chamber.
Cressi owned a patent for the Medusa mask.
Our new system of breathing, that we have designed are patenting, because it doesn’t use the old system of breathing through a central tube system, so it doesn’t require the need for forced breath to travel a longer distance and open more than one valve.
What else makes our mask different from all the others? And how does the Duke allow the diver to breathe freely and also expel CO2 build-upand not fog up the vision chamber?
These three features put Duke in a class of its own:
The advantage of lateral tube position.
An excellent Anti-fogging effect.
A minimal build-up of residual CO2.
The reason why we have chosen to position the tube laterally is because it is the shortest route possible for air flow with minimal effort. And this is currently under patent.
Its left-side tube is divided into two before entering the two separatechambers.
One is connected to the breathing chamber and the other is connected to the vision chamber.
This advantage is enhanced by the fact that neither the breathing chamber nor the tube has any valves to impede the user’s breath.
What’s more, the extraction chamber has an enlarged volume in order to allow for optimal CO2 extraction.
Something interesting to note is, this air flow system in Duke produces far less co2 build-up than a safety gas mask.
We had the opportunity to test it in the laboratory of Milan polytechnic’s engineering department where the results were beyond our expectation.
The second independent tube. It’s connected to the vision chamber, and extracts moisture and warm air that builds up in this chamber, completely separate from the breathing chamber.
Duke has a deflector, which is also under patent, which maximizes the extraction of warm air produced by the face when the mask is worn, and it is designed to work like a chimney effect forcing air circulation away from the lens.
Finally, Duke has large outlet valves at its base, to drain the mask quickly& easily if it fills up with water.
One large outlet valve below the mouth which has nothing to do with the breathing system.
Bonete Dive Fins
The Mini Bonete are fins for children, with short blade, open shoe and adjustable strap, easy to wear and comfortable, for swimming and snorkeling, but also for the practice of water sports that require fins only in particular situations. This is the case, for example, of surfing and windsurfing in all their variants, rafting, canoeing, etc.
In this version, a super-flexible, very resistant low-profile polypropylene has been introduced, which allows an extreme use of the fin without problems of breakage or bending and which also guarantees total safety, in the event of accidental impacts during the activity, both in the pool and at sea.
The design has been studied to guarantee a light and relaxing fin.
