TUSA Liberator Plus TM5700Q Dive Mask
The TUSA Liberator Plus is a straightforward twin-lens mask for scuba diving and snorkelling. Its compact shape keeps the internal volume low, while optional MC-5000 corrective lenses give you another way to tailor the mask to your vision needs.
Features and benefits
- Low-volume design: Needs less air to clear than a comparable mask with a larger internal space.
- Two-window view: Provides separate front lenses in a compact frame.
- Silicone skirt and adjustable strap: Let you find a comfortable position and fine-tune the tension.
- Optional MC-5000 lenses: Compatible negative corrective lenses are available separately; contact us to check lens availability.

Care and storage
Rinse your mask with fresh water after each dive or snorkel, flushing salt and sand from the buckles before adjusting them. Let it dry in the shade, then store it in a protective case away from heat, direct sunlight and coloured rubber gear that can stain the silicone.
For cleaning, use a diluted neutral cleaner suitable for masks and rinse it away completely. Avoid strong chemicals, abrasive scrubbing and flame treatment. Check the skirt, strap and buckles for damage before use.
