The Piezo Megaphone from Pyle is a force to be reckoned with!
Extremely effective in both indoor and outdoor applications, and the attached microphone makes it easy to speak into.
This dynamic megaphone pumps out 50 watts of power that has a range of one mile, and a built in siren to get everyones' attention. Other features include a 10-second recording function so you can play back prerecorded messages, and a volume control that allows you to adjust the sound to your preference. Can be operated using the included rechargeable battery, 8-C batteries or a DC 12V power supply (not included).
