Emergency Survival Whistles 2 Pack – Loud Double-Tube Metal Safety Whistle with Key Ring, Waterproof , for Camping Hiking Boating Outdoor & Dog Training(Do not block the small hole in the middle.)

Be heard when it matters. These Emergency Survival Whistles use a pealess double-tube design to deliver a crisp, penetrating blast that cuts through ambient noise and carries long distances. Crafted from anodized aluminum alloy, the whistles are tough, corrosion-resistant, and light enough to ride on a keychain without adding bulk. Built for all-weather performance, the pealess construction won’t freeze or fail when wet, making it a smart choice for boating, kayaking, hiking, camping, trail running, and roadside emergencies. Each whistle includes a key ring for quick attachment to packs, PFDs, belts, or zipper pulls. The 2-pack ensures you have a spare for a partner or a second kit, and the high-visibility orange finish is easy to find. Use cases: SOS signaling, outdoor safety, lifeguard/marine use, refereeing or dog training cues. Note: Very loud at close range—avoid blowing directly near ears.
