MANTIS LV

Delivering both refined styling and
maximized performance,
this is the ideal twin-lens mask
for skin diving and for scuba diving.

UV420

Less than 400nm of ultraviolet rays of UV-A are cut 98%.Cutting near infrared rays helps preserve the composition of lutein.

  • WIDE SIGHT IS SECURED Inclination 10 degrees
    Inclination 10 degrees

    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.

    All-in-one design ensures firm but gentle contact with the face. When you pull on the strap, you get an effective seal that is less likely to leave impressions on your skin.

  • NO STRESS Soft damper

    Normally, due to pressure squeeze and other causes, mask frames designed to improve the downward arc of vision tend to exert more pressure on the cheekbones. The soft damper relieves this stress.

    While the mask is fitted, the release buckle and fine pitch strap adjustability make it easy to find the most comfortable fit. Even wearing thick gloves, you can easily adjust the mask using one hand.

  • DIFFICULT TO LEAK Leakless system
    Leakless system

    Water is most likely to flood the nose and mouth area when gaps open in the seal between mask and skin. This may happen, for example, if the mask rides up on the face, and if leaking occurs at the cheeks when you are adding a mouthpiece or at the the corners of the mouth when you grin underwater. Here, to avoid compromising the seal when your facial muscles move, the mask form is optimized to maintain fit and feel.

Performance

UV420 CUT lens

The UV420 Cut lens is able to block harmful HEV (highenergy visible light in 400 to 420 nm spectrum) which causes oxidative stress and deterioration of lutein.* * People say that lutein acts like natural sunglasses. It is present as a pigment in the retina, the crucial part of the eye that receives light and lets you see. Here, helping to prevent cumulative macular degeneration, it blocks 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.

How a tunnel looks with different colored light Orange light makes objects more visible by in increasing the contrast of shadowed edges. White light increases overall visibility by generally lighting everything more brightly.　As in the orange-lit tunnel, a UV400 amber lens increases contrast. Meanwhile, a UV420 lens lets everything remain brighter overall. White LED light

An eye behind an ordinary lens

Light tends to cause oxidative stress and lutein (pigment) deterioration.

An eye protected by a UV420 Cut lens

Protection of lutein reduces oxidative stress:less pigment deterioration.

Low Volume

Volume: 110cc Weight: 220g
Inheriting the shape of the Mantis mask, The Mantis LV excels at having low inner volume increasing its up-down, left-right field of view. A broader field of view provides overall increased visibility and comfort when diving.

Inclination Angle: 10° Left-Right: 117°

Downward vision is increased by the 10°tilt and lens shape allowing divers to more easily view the chest area where essential diving operations take place.
