The Tusa M-211S Freedom One Pro Mask features a fit on medium to large adult faces that's so free you hardly notice you're wearing it.
Tusa's Freedom One Pro Technology, a set of revolutionary new mask features which deliver superior fit, comfort and increased performance. The Freedom One Pro also offers TUSA's new Crystalview Optical glass with AR/UV lens.
The Freedom One Pro features TUSA's all new ClearView Optical Glass treated with a proprietary anti-reflective (A/R) and ultraviolet (U/V) coating up to 20 layers thick. This unique ClearView AR/UV lens offers the diver enhanced colour, clarity, contrast and eye protection without sacrificing light transmission or vision on the surface or underwater.
TUSA ClearView Optical Glass Lens
TUSA's ClearView optical glass lenses provide superior clarity, colour and transmission of light over standard glass lenses used by the competition. Up to 15% of available light can be lost with a standard glass lens due to impurities and reflectivity. TUSA's ClearView lenses transmit 92% of available light to the diver for clear crisp vision.
Anti-Reflective (A/R) Lens Treatment
Standard glass lenses can reflect up to 15% of available light reducing vision underwater. TUSA's Anti-Reflective (A/R) Lens Treatment decreases internal and external reflected light. This reduction increases light transmission to 95% resulting in significantly enhanced colour, clarity, contrast and better overall vision underwater.
UV Lens Treatment
Increased exposure to UV light can damage the eyes especially in marine environments where reflectivity is high. TUSA's UV Lens Treatment provides 100% protection from harmful UVA and UVB rays. Blocking 100% of the ultraviolet spectrum (under 400 nm) provides greater eye protection without sacrificing light transmission or vision.
Freedom One offers the following revolutionary three specific design features:
Dimpled Skirt: Key areas around the forehead and cheek bones have been designed with dimples which combine to increase the skirt's softness, flexibility and skin surface contact.
This also greatly reduces leakage and enhances comfort.
Varied Silicone Thickness:
A regulator or snorkel mouthpiece, when in use, can cause areas of the mouth and nose section to distort causing leakage and discomfort. Varied thicknesses of silicone in these key areas reduce leakage and provide a better fit.
As water pressure increases a mask will compress inwards toward the face often causing further leakage. Areas under the cheek bones have been reinforced with stability ridges to minimize this compression maintaining ideal skin surface contact.
