ACME - Slimline Tornado 636 Whistle - Suitable for Open or Noisy Envinroments - Flat Dual-Chamber Design - High-Pitch Loud Sound - Compact Signalling - Self Defence, Sports and Outdoors Whistle

SOLAS COMPLIANT, CERTIFIED FOR MARITIME LIFE-SAVING EQUIPMENT: The ACME 636 Slimline meets the SOLAS (Safety of Life at Sea) standard, making it a certified, compliant inclusion in maritime safety equipment, life jackets, and buoyancy aid safety packs where regulatory certification is a requirement, not simply a desirable feature. FLAT SLIMLINE PROFILE, ENGINEERED FOR LIFE JACKET AND BUOYANCY AID INTEGRATION: The 636's flat, slimline form is designed specifically to integrate with life jacket safety pouches, PFD attachment points, and emergency kit pouches without adding bulk, creating snagging hazards, or interfering with the fit of water safety equipment. POWERFUL OUTPUT FROM MINIMAL LUNG CAPACITY, CRITICAL IN EMERGENCY CONDITIONS: The easy-blow design produces a high-volume rescue signal without requiring strong or sustained breath. In a genuine water emergency where cold-water shock, exhaustion, or physical distress reduces a casualty's breathing capacity, a whistle that signals powerfully with minimal effort is not a convenience, it is a life-safety specification. SUITED TO SAILING, KAYAKING, PADDLEBOARDING AND ALL WATER SPORTS: Any water sport involving a life jacket or buoyancy aid should include a certified signal whistle as a matter of course. The ACME 636 is designed precisely for this role, SOLAS-certified, compact, integrated, and functional immediately after submersion. ALSO SUITED TO COASTAL WALKING, HIKING AND OUTDOOR SURVIVAL KITS, Beyond maritime use, the 636's flat profile and high-output acoustic performance make it a practical signal whistle for any outdoor emergency kit. It stores without wasted space, works in all conditions, and requires no preparation.
