GULL MANTIS LV MASK 2021 (GM-1267)
Delivering refined styling with maximized performance, this is the ideal twin-lens mask for skin and scuba divers.Equipped with UV420 lenses and a skirt uniquely designed for increased comfort. MANTIS LV’s exclusive lens shape, low-volume construction, and optimized inclination angle allow for an extended field of view.
Inclination 10 degrees
The lens shape and inclination angle work together to extend the mask’s downward field of view toward the chest level. This helps with essential diving maneuvers that are carried out at the chest level.
Curled Skirt Lip with Integrated Strap
The skirt’s all-in-one design ensures firm but gentle contact with the face. Pulling on the strap keeps a tight yet gentle seal leaving fewer impressions on your skin.
Normally pressure causes an uncomfortable squeeze, especially for masks with downwards inclination angles for improved downward field of view. The soft damper skirt acts as cushions to relieve this stress on the face.
The drain skirt design improves water expulsion when clearing the mask and also minimizes water pooling.
Reduced inner volume of the mask promotes a wider vertical and horizontal field of view.
DX Spec. Mask Buckle
The release buckle and fine pinch strap adjustability make it easy to find the most comfortable fit even when wearing thicker gloves. Can be adjusted with only using one hand.
UV420 CUT Lens
The UV420 CUT lens is able to block harmful HEV (high-energy visible light in the 400 to 420 nm spectrum) which causes oxidative stress and deterioration of *lutein in your eye. Lutein is said to act as natural sunglasses. It is present as a pigment in the retina, a crucial part of the eye that receives light and allows you to see. The UV420 lens prevents cumulative macular degeneration by blocking harmful light and has an anti-oxidant effect. Lutein is destroyed when it absorbs harmful light. Its presence in the retina is limited and, because the body cannot make lutein, it can only be replaced by eating lutein-rich food.
Lighting can alter the appearance of a tunnel. Orange light make objects more visible by increasing the contrast of its shadowed edges. White light increases overall visibility by generally illuminating everything brighter. As in the orange-lit tunnel, our previous UV400 Amber lens increases contrast, while the UV420 CUT lens provides a brighter visual such as with white LED light.
Eye Behind an Ordinary Lens
Light tends to cause oxidative stress and lutein (pigment) deterioration.
Eye Behind a UV420 CUT Lens
Protection of lutein reduces oxidative stress:less pigment deterioration.
Two Types of High-Performance Lenses
UV420 CUT Aqua LensUV420 CUT eye protection blocks out harmful UV and near infrared rays. Cutting out near infrared rays helps preserve the composition of lutein which is crucial for healthy vision. Overall visibility is effectively enhanced by the bluish tint offering a brighter field of vision.
Super Clear LensEnables greater clarity than standard glass. Objects are seen more clearly. By rigorously removing impurities from the glass, light transmittance is maximized. Skirt reflections on the lens are also minimized with a clear silicone mask.
The UV 420 Cut difference*Photograph isrepresentative.
Volume: 110cc Weight: 220g Inherits the form of the Mantis, but with reduced mask volume and even wider up‒down and L‒R arcs of vision. Wherever you dive, see across a wider ﬁeld of view. *Measured using Gull standard procedures.
Left-Right: 117° Up-Down: 103° Inclination: 10°
The inclination angle and shape of the lens work together to extend the downward field of vision. You can see better through the arc down to chest level, which is where most diving tasks are carried out.
