The 70mai E1 is a circular polarizing lens filter designed to improve the visual quality of your dashcam recordings. By reducing glare and reflections from non-metallic surfaces such as glass, water, or foliage, it helps you achieve better image clarity and more vibrant colors in your footage. You can easily fine-tune the polarization level thanks to the rotatable design of the filter. This accessory is compatible with a wide range of models, including the A500S, A510, A410, A800S, A800SE, A200, as well as the D08 (Lite) and D10 (Lite 2), making it a practical addition for drivers who want to minimize dashboard reflections on the windshield.
