The three LED lights provide powerful illumination throughout the dive. The beam of light can be adjusted by the diver with a simple twist of the lens head. The intensity of the light can be adjusted through the user-friendly, mechanical multi-function switch with battery charge indicator, which is very useful for keeping the battery under control, even during a dive. Intuitive and safe, it prevents any water penetration into the lens. With a simple touch, you can adjust four different functions of the lens: full power, approximately 40% power, flashing, and off. A new, double-click electronic safety arrangement on the switch prevents accidental activation.
