Description The Explore E3 has the most advanced optics available on the market. These optics are designed exclusively by OceanLED and offer a truly striking 90 deg surface beam angle with a focused 20 deg side beam producing a blade of light under the water that penetrates further, illuminating a larger area with minimal loss. The ultra low profile outer face of the housing is designed for vessels wanting to go fast and have no impact on speed or flow of water over the hull.
