Tech Pro has created the Sonar mask specifically for spearfishing and free or autonomous diving. Constructed with Frameless technology (direct silicone injection onto the glass) and without a frame, it is a lightweight, durable, and easily storable mask. The medium internal volume corresponds to approximately 127ml and contributes to easier cleaning and balancing of internal pressure, performing exceptionally well in deep dives.

It features a wide sealing ring for excellent grip and unprecedented comfort, as well as an additional lip, both internally and externally, that provides sealing and relative rigidity when diving at greater depths. Additionally, the small distance between the eyes and Tempered glass lenses offers a panoramic field of vision with exceptional peripheral visibility, without blind spots.

The internal frontal design and the horizontal pocket on the nose minimize the uncomfortable pressure on the forehead or upper part of the nose, even after long hours of diving. Lastly, the strap skirts, made of POM material, are ergonomically designed with double buttons and cylinders that allow for easy and precise strap adjustments.
