SOS Marine Rescue Laser Light is a hand-held day and night-time laser signalling device that provides a convenient, effective way to signal a rescue party. Its waterproof, rugged design combines the safety of a laser signalling device with the convenience of a flashlight. This is the compact model preferred by military, hikers, kayakers, and other outdoor enthusiasts that want to minimize weight. Unlike pyrotechnic flares, the Rescue Laser Light is non-flammable, environmentally safe, and can operate continuously for 40 hours on a single, long-life, replaceable CR123 lithium battery (available at most convenience shops and wherever camera batteries are sold).
