Air horns are able to make an amazingly loud sound from such a small little canister thanks to the magic of air pressure. There’s probably nothing more annoying than an air horn blasting in your vicinity but clearly these devices do have their legitimate uses beyond just dicking around. If you’re a boater, you know how indispensable an air horn can be to alert other boats of your presence and to signal for help. Sports fans love to use these to get their team’s fans pumped up and cheering.
Most air horns are not eco-friendly; they have an aerosol can that you use until it runs out and then throw it away. The Eco Blast Rechargeable Boat Air Horn is eco-friendly- it’s the last air horn you will ever have to buy because it’s refillable. Just hook it up to the included pump or any bicycle pump, car tire pump, or compressor and fill it up with more air and you can use it over and over again. Each recharge gives you 70 horn blasts. The volume is adjustable up to 115 dB this air horn meets Coast Guard regulations.
The Ecoblaster Rechargeable Air Horn is available for $29.98
