Whether you are an emergency responder en route to a call, or you need to alert the community about a bigger threat such as a tornado, you need to have a way to reach as many people as possible. An air raid siren is one of the most effective ways to reach a large population. Traditionally used to notify of an air raid in times of war, these sirens come with a loud wail or horn and have been modified to become emergency response alerts. Miniature models attach easily to a boat or vehicle and can be used to alert traffic as you drive on the way to an emergency. Portable, handheld models work with a hand crank and are designed to get people's attention at any spot. While they are typically associated with emergency response, these siren air horns do not always need to mean danger — root for your favorite sports team at a big arena with these loud devices. Browse the large selection of air raid sirens on eBay to find the model you need to make your presence known.
