TUSA Intega Prescription Mask With Gauge Readers

The TUSA Intega Prescription Mask With Gauge Readers combines TUSA’s exceptional Intega fit with positive bifocal corrective lenses designed to make reading dive computers, gauges, cameras and other close-up equipment easier underwater.

Ideal for divers who need near-vision correction but still want clear distance vision, the gauge reader lenses feature a positive prescription section in the lower portion of the lens only. The upper section remains non-prescription, allowing you to look ahead normally while having magnification available when you glance down at your instruments.

Built around TUSA’s advanced M2004 Intega Dive Mask, this is a premium prescription scuba mask offering a low-volume design, wide field of view and exceptional comfort across a broad range of face shapes.

Positive Gauge Readers for Close-Up Vision

Unlike a full prescription lens, the TUSA positive gauge reader works much like a bifocal reading lens.

The upper section has no corrective power, while the lower section contains your selected positive diopter. Simply look down through the reader section when checking your dive computer, pressure gauge, compass, camera controls or other equipment.

Positive corrective powers are available from +1.0 to +4.5 diopters in 0.5 increments, with left and right lenses selected independently.

This makes it possible to configure different strengths for each eye where required.

Gauge Reader Lens Options

• Positive diopters from +1.0 to +4.5
• Available in 0.5 diopter increments
• Left and right lenses available separately
• Lower lens section provides close-up correction
• Upper lens section remains non-prescription
• High-quality optical glass
• Ideal for reading dive computers and gauges underwater
• Compatible with TUSA Intega M2004
• Compatible with TUSA Freedom One M-211

Important: Positive diopter powers relate to the spherical component of your prescription. If you are unsure which strength is suitable for each eye, consult your optometrist before ordering.

Designed to Fit More Face Shapes

One of the standout features of the TUSA Intega M2004 is its ability to accommodate an unusually wide range of facial profiles.

TUSA’s 3D SYNQ Technology incorporates a specially designed fitting ring into the silicone skirt. This allows the skirt to adapt more naturally to wide, narrow, long and short face shapes while maintaining a comfortable, reliable seal.

The result is a prescription dive mask that provides excellent comfort without requiring an excessively tight strap.

20% Wider Field of View & Low-Volume Design

The Intega positions its lenses closer to the eyes to provide a low internal volume and an exceptionally open field of vision.

TUSA states that the Intega provides approximately 20% wider visibility compared with previous TUSA mask designs, helping improve peripheral awareness while diving.

Its low-volume construction also makes the mask easier to equalise and clear.

3D SYNQ Technology

TUSA’s 3D SYNQ Fitting Ring is integrated directly into the mask skirt and helps the silicone conform to different facial contours.

Rather than relying solely on strap tension to create a seal, the skirt is designed to naturally adapt to the diver’s face. This helps provide a comfortable fit across a wide variety of face shapes.

Swift Buckle 3D

The low-profile Swift Buckle 3D system provides smooth and simple strap adjustment while keeping the buckle assembly compact.

Its three-dimensional movement helps the strap sit naturally around the head and makes adjustments easy before or during a dive.

Freedom Technology

TUSA’s proprietary Freedom Technology uses varying silicone thicknesses, stability ridges, a dimpled skirt surface and a low-friction fitting surface to improve comfort and sealing performance.

These features help the mask maintain a secure seal while reducing unnecessary pressure against the face.

Patented 3D Mask Strap

The TUSA 3D strap is shaped to follow the natural curvature of the back of the head.

Compared with a traditional flat silicone strap, its three-dimensional design helps distribute tension more evenly for improved comfort and stability throughout the dive.

Round Edge Skirt

TUSA’s Round Edge Skirt uses a rounded silicone sealing surface rather than a conventional sharp edge.

This creates a softer contact point against the skin, helping reduce pressure, improve comfort and minimise facial marks after diving.
