Masks for Spearfishing

Masks for spearfishing low-volume. Single-lens and dual-lens models, with anti-fog and mirrored lenses. Camouflage colors and silicone skirts. Wide field of view and quick equalization.

Masks for Spearfishing

The mask is one of the most critical pieces of equipment for a spearfisherman. Unlike snorkeling or recreational diving masks, those designed for spearfishing and freedive spearfishing are built around a key technical principle: low internal volume. A reduced volume between the diver’s face and the lenses means less air is needed to equalize during descent, reducing lung air consumption during equalization and making the mask easier to manage at depth.

Deep Blue’s selection in this category includes over 60 models, divided between dual-lens and single-lens masks, with a wide variety of colors and camouflage patterns. The range covers every level of use, from beginners to experienced spearfishermen.

Types of masks in this category

The main distinction in the catalog concerns lens configuration.

Dual-lens masks: these represent the vast majority of available models. They feature two separate lenses, one for each eye, often mounted in a shared frame. On some models, this configuration allows the lenses to be replaced with prescription versions, which is useful for divers with vision correction needs.

Single-lens masks: available in several models in the catalog. The single lens provides a wider, more uniform field of view, with no central visual divider. Internal volume tends to be slightly higher than on dual-lens models. This type is appreciated in situations where field of view is a priority.

A second distinction concerns lens treatment:

Standard lenses: the standard configuration, found on most models, is a tempered lens with no anti-fog treatment.
Antifog lenses: a treatment applied directly to the inner surface of the lenses, reducing condensation during use. There are two solutions: antifog films or Plasma treatment. They are currently available on numerous Salvimar models and on most of the C4 line, with both solutions.
Mirrored lenses (mirror lenses): reflective outer surfaces that reduce intense light entering the mask in strong sunlight at the surface, and prevent fish from seeing the spearfisherman’s eyes.

How to choose a mask for spearfishing

Choosing a spearfishing mask depends on several technical parameters that are worth evaluating before purchase.

Internal volume: in spearfishing, low-volume masks are preferred. Reduced internal volume requires less air for equalization and allows more agile management during breath-hold dives. All models in this category are built with this priority.

Silicone seal: the quality and softness of the silicone skirt determine how effectively the mask seals against the face. A skirt that is too rigid can create pressure points and leaks. Soft silicone models provide a reliable seal across different face shapes. Some models feature dual-face or double-edge skirts to increase the sealing surface.

Field of view: low-profile dual-lens masks offer a wider downward view, useful for monitoring the underwater environment while hunting. Low-profile masks, such as some C4, Salvimar and Cressi models from the Nano and Calibro lines, combine low volume with good angular visibility.

Antifog treatment: lens fogging is a common issue during air-to-water transitions. Models with integrated antifog treatment keep the lenses free from condensation without the need for preliminary preparation with specific products.

Antifog lenses equipped with an internal film require no preliminary operation; the mask simply needs to be clean and they work immediately. However, since these are plastic films, they must not be damaged or scratched.

Antifog lenses equipped with Plasma treatment have no film, but they must be activated before use. To activate the Plasma treatment, simply immerse the mask in water for 1 minute.

Face shape: there is no universal mask. Nose shape, face width and eye socket depth all affect the seal. Models such as the Sigal Sub X-Wide are built for wider faces, while compact masks like the Cressi Nano are suited to narrower face shapes. Read the features of each mask to understand which one may be most compatible with your face shape.

Materials and technical features

Silicone: the material used for the skirt and strap on modern models. Silicone is chemically stable in the marine environment, resistant to saltwater and weathering, and maintains its elastic properties over time. Unlike rubber, silicone does not stiffen in cold conditions and does not tend to degrade with prolonged UV exposure.

Tempered glass lenses: all models featured use tempered glass lenses, not plastic. Tempered glass delivers better optical performance than polycarbonate, with less peripheral distortion and greater scratch resistance. The mechanical strength of tempered glass is significantly higher than ordinary glass in the event of impacts.

ABS or composite frames: the load-bearing structure of the masks is generally made from rigid technopolymer resins. On higher-end models, such as some C4 versions and the Cressi Quantum, frames feature specific finishes or selected materials to reduce weight and improve aesthetics.

Adjustable straps: all models featured come with a strap and adjustment system. In some cases, such as on Salvimar, Cressi, Mares, C4 and other models, the replacement strap is available separately as a spare part.

Anti-fog treatment: pre-cleaner and antifog for standard masks

Masks with lenses that do not have an integrated antifog treatment tend to fog for a precise technical reason: during molding of the silicone skirt, manufacturers add silicone oils to the raw material to facilitate processing. These oils gradually migrate toward the glass lenses, depositing a thin film that alters surface tension and causes fogging. Water, saliva and generic products do not reliably remove silicone oils. The solution requires two specific products used in sequence.

Pre-treatment (Cleaner) is a patented degreaser formulated to permanently remove silicone oils from the lenses without damaging the silicone or plastic parts of the mask. It should be sprayed onto dry lenses, rubbed vigorously for 4-5 minutes, left to act for 10 minutes and then rinsed. The cycle should be repeated 3-4 times. This treatment is performed once on a new mask, not before every session. It removes the silicone oils that cause fogging.

Once contamination has been removed, before each use in the water it is recommended to apply an Antifog product in spray or gel form. Spray it onto the inner surface of the lenses, leave it to act for 2 minutes and rinse. This ensures that masks equipped with standard lenses do not fog.

Practical use

The spearfishing masks in this category are designed for use in marine environments, both for coastal spearfishing close to shore and in open water. Their construction features—low internal volume, soft silicone, tempered glass lenses, antifog—make them suitable for repeated freediving sessions where air management is a determining factor.

Camouflage versions such as military green, brown or camouflage patterns are used specifically for spearfishing around rocky areas and seagrass beds, where reducing the spearfisherman’s visual impact helps with approaching prey.

Models with antifog lenses are especially useful during boat-based fishing sessions, where the diver frequently moves between warm air and water, a situation that encourages condensation on the lenses.

Single-lens masks are mainly used in situations where a wide field of view is a priority, where identifying prey at a distance is critical.

Some models, such as the H Dessault Element, can be equipped with an optional camera mount, available separately, allowing video recording during a spearfishing session without altering the mask’s performance characteristics.

Conclusion

Deep Blue’s spearfishing masks category brings together over 65 models from nine specialized brands, organized by lens type, optical treatment and color. The predominance of low-volume dual-lens masks reflects the technical needs of freedive spearfishing, where air management during descent is a determining factor. Integrated antifog treatments, mirrored lenses and camouflage colors meet specific operational needs, from spearfishing in structured environments to bluewater hunting in open water. The availability of accessories such as replacement straps, mask carrying boxes and lens treatment products completes the range for those who need to maintain or protect their equipment.
