FAQs

What face size is the Raven designed for?
Promate describes the Raven as ideal for medium faces.

What is a low-volume mask?
A low-volume mask has less air space between the diver's face and the lens. This keeps the lens closer to the eyes for a more compact profile and can make the mask easier to clear. Promate describes the Raven as an extremely low-volume mask with a wide 170-degree field of view.

What is tempered glass?
Tempered glass is heat-treated to make it stronger than ordinary glass. If it is broken, it is designed to fracture into smaller pieces rather than large, sharp shards, which is why it is commonly used for dive-mask lenses.

Does the buckle swivel?
Yes. The quick-release swivel buckle can move through various angles and allows the strap to be removed from the buckle system.

Its combination of extremely low volume, a 170-degree field of view, soft liquid silicone, and an adjustable swivel buckle is particularly appealing for medium-face profiles where a close, streamlined fit is preferred.
