HammerHead MV3 Action Freediving Mask

Overview

The HammerHead MV3 Action is a low-volume dual-lens mask for freediving and spearfishing with a GoPro-compatible action-camera mount integrated into the frame. Its compact internal volume keeps the lenses close to the face, reducing the amount of air required for mask clearing while supporting hands-free point-of-view recording.

Optics for different conditions

APEX optic-grade glass is manufactured with iron oxide impurities removed to improve light transmission and reduce the green tint associated with conventional glass. Depending on the selected lens treatment, the optical emphasis changes between neutral clarity, increased contrast and depth perception, anti-reflective light transmission and color perception, or glare reduction in bright and shallow conditions. This allows the lens configuration to be matched to the expected diving environment.

Camera integration

The GoPro-compatible mount forms part of the mask frame rather than relying on a separate aftermarket mask attachment. It positions the camera for first-person recording while leaving both hands available for normal freediving or spearfishing activities. A GoPro camera is not included.
