Scubapro FM2 Full Face Mask

Hold the mask against your face without using the strap, look slightly down, and inhale gently through your nose; a well-fitting mask holds itself in place for a few seconds. Check that the skirt seals all the way around without digging into the nose bridge, and that there are no gaps at the temples or above the upper lip. A mustache can break the seal even on an otherwise well-fitting mask.

New masks carry a residue on the inside of the lens left over from manufacturing, and defog cannot stick to it, so the mask fogs until that film is removed. The standard pre-treatment is to scrub the inside of the lens with a mild abrasive cleaner or a dedicated mask prep and rinse thoroughly, repeating if it still fogs. Follow the mask manufacturer's instructions, particularly on coated or mirrored lenses.

Apply defog to a dry lens before the dive, spread it over the whole inner surface, then rinse briefly with water just before you put the mask on. Fogging happens when warm moist air meets a cooler lens, so a clean lens with a thin surfactant film is the fix. Keep sunscreen off your fingers before handling the inside of the lens, because that film fogs badly and is hard to remove.

Dive mask lenses should be tempered safety glass because it resists scratching and, if it ever does break, fractures into blunt granules rather than sharp shards next to your eyes. Untempered or plastic lenses scratch easily and can craze, which is why tempered glass is standard on scuba masks. Look for the tempered marking etched on the lens.

Yes, prescription options are widely available, usually as masks fitted with stock corrective lenses in set diopter steps, custom-ground lenses installed in compatible frames, or bonded lenses added to an existing lens. Not every mask frame accepts replacement lenses, so check compatibility before you buy the frame. An optician or a dive shop can help translate your glasses prescription into a mask lens choice.

Rinse it in fresh water after each dive day and let it dry away from direct sunlight, avoiding anything abrasive on the treated inner lens. Store it in a rigid mask box so the skirt is never compressed or creased, since a set crease in the skirt is a permanent leak. Keep silicone skirts away from petroleum products and prolonged UV, both of which yellow and harden them.

Not tight at all in the usual sense, because over-tightening is the most common cause of both leaks and headaches; a hard-pulled strap distorts the skirt and lifts the seal off your face. The strap should sit high on the back of your head and be just firm enough to keep the mask from shifting. If you need it cranked down to stop a leak, the mask does not fit your face.

A full face mask is safe when it is built and used for the job, and the FM2 is designed around that. It is CE certified in combination with the SCUBAPRO MK25 EVO / S620Ti regulator, its field of vision meets the latest EN250 standard, and it accepts two second stages at once for a redundant air source selected by the breathing effort knob. A one-way chin purge valve allows hands-free clearing. Full face diving requires specific training.

The FM2 keeps SCUBAPRO's familiar three-port layout, but the fittings are larger to accept SCUBAPRO's latest generation of second stages. The mask is CE certified as a system with the MK25 EVO / S620Ti regulator. Two second stages can be mounted at the same time for redundancy, and you switch between them with the breathing effort knob. Contact us at 888-701-4017 to confirm your regulator.

Scubapro publishes the FM2 with a black silicone skirt sized for an average to medium face, with no other color variants listed. The skirt uses a double soft seal in soft high-grade silicone so it adapts to a range of face sizes and shapes, and the five-arm spider strap with one-hand quick-adjust buckles lets you balance tension evenly around your head.

Yes. The FM2 lens frame has a built-in HUD attachment point plus threaded metal inserts, so lights, cameras and other accessories can be bolted directly to the frame instead of being strapped on. The mask is also compatible with underwater communication systems used by professional divers, and all parts are replaceable, so mounting hardware and components can be serviced over time.
