This is the same sound at the same volume as disposable compressed gas air horns, but for a much longer duration (20 times longer) per battery charge than a single disposable gas air horn.
Disposable compressed gas air horns have proven to be unreliable and are extremely bad for the environment. A single 5 oz. can will only last a minute or so at best, it may not work at all in cold weather, and its sound volume diminishes the longer you use it. It also uses an extremely potent greenhouse gas as a propellant versus the Hornet Sport rechargeable electric air horn only uses air, and it will reliably...
