Product DescriptionThis safety combo comes with a whistle, signal mirror, and float, all connected by a lanyard for convenience. The highly visible yellow float is easy to see if dropped in the water. The survival whistle has a unique flat design that prevents it from holding water. Emits a 102 dB shrill dual tone. The unique Hot Shot Signal Mirror features a holographic "red-dot" viewing window that helps in finding the optimum sighting spot for a bright, focused signal. A great idea for adding to all your PFDs.
