With the Harmony Gear Paddler's Horn, it's easier than ever for sea kayakers to call for help after taking a swim.  The Paddler's Horn operates like a traditional whistle but provides a lot more kick and creates a loud, distinct, attention grabbing noise that closely mimics the tones of larger ships.  The Paddler's Horn can be operated with one hand, requires no batteries and stows easily in your kayak for immediate access. A good signaling device is essential for anyone who wants to paddle in open water.
