Zeagle Scope Dual Dive 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.

It refers to a patented frame design where the subframe sits fully submerged with exposed silicone around it, which Zeagle states increases protection. Zeagle also states this is the only dual-lens mask built with this specific subframe design, distinguishing it from standard framed or frameless dual-lens masks.

Yes. The mask ships standard with a grey silicone strap, but it is compatible with the Zeagle Scope Mask Color Kit, which adds strap color options in Aqua, Black, Blue, Pink, Purple, Red, or Yellow, available in either silicone or elastic strap material.

The Zeagle Multi-Tool that comes with the Scope Mask Color Kit is compatible with both Scope Dual and Scope Mono masks, Zeagle Recon Fins, and Zeagle regulators. The Scope Mask Color Kit is compatible with the Scope Dual Mask, adding strap colors and colored lens retainers.

Zeagle covers the Scope Dual Mask with a limited 1-year warranty against defects in materials and workmanship under normal diving use. The warranty covers replacement parts but excludes labor and shipping, and it is void if the mask is altered, neglected, misused, or serviced by an unauthorized dealer.
