2 Pack Dual-Tube Aluminum Alloy High Decibel Emergency Survival Whistle Keychains
Constructed from lightweight aviation aluminum alloy, independent dual air tube design delivers up to 150dB ultra-loud dual-frequency penetrating sound. The sharp far-traveling tone easily cuts through wind, mountain fog, thick woods and disaster rubble, serving as full-function SOS signaling gear for hiking, climbing, camping, boating and all wilderness emergency scenarios.
Frosted anodized metal casing boasts outstanding waterproof, rust-proof, scratch-resistant and colorfast performance, keeping steady consistent sound output under rainy, damp, waterside and harsh wild environments without oxidation or fading. Slim vertical streamlined body is ultra-lightweight, bringing nearly zero extra carry weight for long-distance outdoor treks.
All blowing contact edges are precisely polished into smooth rounded curves to prevent lip abrasion during long-time continuous blowing. Seamless one-piece integrated construction contains no loose fragile internal components that jam or fall off, simple to wipe clean of outdoor dust and water stains.
Compact multi-functional portable EDC lifesaving tool for mountain climbers, hikers, outdoor adventurers, lifeguards and household emergency preparedness kits.
