Hammerhead MV3 Mask w/ Integrated GoPro Mount

APEX Lens Technology is featured in 100% of HammerHead Spearguns dive masks. APEX Technology increases light transmission over standard tempered glass by over 13%. That means you should see 13% πr2 more lobsters, octopus, or fish!

APEX lenses are manufactured in a process that eliminates iron oxide impurities for 13% increase in light transmission over standard tempered glass. Advanced technical lens coatings are then applied to the APEX glass for the most extreme of dive applications.

The exceptional clarity of optic-grade glass affords the lenses adaptability in a wide array of environments. With no trace of iron impurities in the glass, distortion is greatly reduced, while more light passes through.
