Freedom technology is a set of revolutionary features offering superior fit, comfort and increased performance in TUSA masks.   Freedom model masks feature a dimpled skirt surface with varied silicone thicknesses and stability ridges in addition to a proprietary low-friction skirt surface on the fitting line.

3-D Strap
TUSA's patented 3-D strap is a true three-dimensional design that snugly fits against the head's natural curvature. The 3-D strap offers unprecedented comfort and fit unlike standard flat mask straps.

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.

CrystalView Optical Glass
CrystalView optical glass lenses provide superior clarity, color 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 CrystalView lenses transmit 92% of available light to the diver for clear crisp vision.  CrystalView lenses are used in all PRO models masks and also in the M-41 Freedom Quad.

Round Edge Skirt
TUSA's Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The "planar fit, instead of linear fit" silicone skirt maintains great fit and unprecedented comfort.

Skirt Mounted Quick-Adjust Buckle System
The Quick-Adjust Buckle System incorporates a newly-designed low-profile buckle into the crystal silicone skirt of the mask. The result is a compact, lightweight, technologically advanced mask design that can be easily and quickly adjusted for a perfect fit.

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.


Tusa Prescription Information

Accepts MC-7500, step diopters -1.50 to -8.00 in 0.50 increments.  For information on picking the right lens powers for your prescription, see FAQ page on how to read a prescription. We recommend having lenses installed.  It is really difficult to install yourself and if you install yourself, the seal may no longer be rated for depth.

Also can be made custom made with the exact prescription lenses made directly into the mask.  Call for email for more information.
