This is a Hand Operated Warning Siren which you can crank the handle continuously to produce loud warning sound up to 1/4 mile away. Unlike other type of hand-held sirens, this one is made of quality aluminum (not plastic) and has military olive drab color. The warning siren only weighs about 2.6lbs so you can easily bring it with you to outdoor and remote area.
You can turn the fan cover ON or OFF to determine how loud you want the warning sound to be. Please view the youtube clip on the left. We also have large size Hand Crank Air Raid Siren with Stand for sale.
