The Tusa Platina Dive Mask eliminates the inner frame that blocks the field of vision and attaches the lens directly to the frame to realise a super-slim frame. The Direct Sashing System (D.S.S.) results in a major increase in the upper/lower-left/right visibility range. It also achieves a major narrowing of the centre joints connecting the left and right lenses to eliminate the vision field split.
Like all Tusa masks, it incorporates a wide range of features to enhance comfort and provide clarity of vision.
