The M-211 Freedom One mask features the newly developed and revolutionary Freedom Technology delivering superior fit, comfort and performance. The Freedom One is the first of next generation TUSA masks offering this innovative new technology combined with superior design, build quality, materials and frame construction.
In addition to Freedom Technology, the M-211 features TUSA’s patented Quick-Adjust Buckle System, 3-D Anatomical Strap, Round-Edge skirt technologies and is available in a PRO version (M-211S) with CrystalView optical glass lenses treated with a proprietary anti-reflective (A/R) and ultraviolet (U/V) coating.
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 color, 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 400nm) provides greater eye protection without sacrificing light transmission or vision.
