ECO BLAST RECHARGEABLE AIR HORN

The refill valve of the Eco Blast air horn lets you recharge using any bicylce pump, service station pump or air compressor. In seconds, Eco Blast is again ready to emit a powerful 120 db signal that meets all U.S.C.G. requirements. There's no worry about potentially harmful chemicals escaping into the environment. Never buy a refill canister again.
