Identify and keep track of your diving partners at depths as great as 328' with the Bigblue Easy Clip Multi-Color Rainbow Marker Light. This beacon features virtually all the colors of the visible spectrum: red, green, blue, purple, orange, and yellow. Additionally, it provides both constant and flash modes for all these colors. The light output is bright enough to be seen by other divers, yet low enough that it won't be distracting. Running on the two supplied CR2032 coin batteries, the marker light has an operating time of 12-24 h. It clips easily onto masks, belts, straps, and other accessories, and includes an adjustable lanyard that will attach to tank valves and buoyancy compensation devices.
