- Instant alert activation: The lifebuoy light automatically flashes at a fast rate, 50-70 times per minute, to increase visibility at sea. It uses an efficient battery that stores power to drive the strobe LED light as a floating beacon. - Convenient test procedure: When the device contacts seawater in an upright position, the strobe LED automatically illuminates, enabling quick, built-in testing of its function. - Enhanced visibility: Equipped with a high-intensity flashing LED, this lifebuoy light is designed to provide reliable visibility in rough seas, helping you locate the lifebuoy quickly. - Waterproof and buoyant design: Safe for continuous use in water temperatures from -1C to +30C, with a waterproof buoyancy construction to keep your lifebuoy visible and your vessel safer in all weather conditions. - Practical applications: - Open-water operations: attach to lifebuoy on deck to mark location during man overboard situations, especially at night. - Night sailing or low-visibility conditions: use as a signaling beacon to improve conspicuity and rescue response time. - Safety checks and trainings: routinely test the device in upright seawater contact to ensure reliable operation.
