The Tusa M19 Visio Uno features a low-profile teardrop design and single window that offers an improved field of view compared to most dual-window masks.
Skirt: Utilizes TUSA’s patented Round Edge Skirt and 3D self-adjusting mask that fits a variety of face shapes, especially suitable for Asian facial structures.
Lenses: The lenses are made of 3mm tempered glass, which is resistant to high pressure and provides high-definition vision. Some versions come with a professional anti-UV coating that blocks up to 99% of UVA and UVB rays and reduces underwater light refraction.
Strap and Buckle: Equipped with a Quick Adjust Buckle System mounted on the skirt and a patented 3D Strap that is designed to fit tightly to the natural curvature of the head, ensuring a secure and comfortable fit.
Volume: It is a low volume mask, which makes it easier to clear water if flooded.
Accessories: It comes with a dedicated hard case for storage and transport.
User Reviews and Experiences
- Reviews from users and experts indicate that the TUSA M19 provides a comfortable and secure fit, with the soft silicone and 3D straps being particularly praised for their comfort.
- The wide field of view and clarity provided by the optical grade or coated lenses are also highlighted as major positives.
- While the mask has a larger internal volume than some ultra-low volume freediving masks, some users find that this design prevents the mask frame from pressing against the bridge of the nose, improving overall comfort. Users recommend cleaning the inner glass surface properly before use to prevent fogging, a common issue with new masks.
