Description: Used megaphone. I tossed in 8 c batteries and the sirens work. Speech works. Don't see an on/off switch so I just open the battery compartment to shut it down. Really not sure how these are supposed to work. So consider it a project. Selling cheap due to condition. ?------------------------------------ This AmpliVox S602M MityMeg Plus 25 Watt Megaphone is a reliable tool for amplifying your voice up to 1760 yards away.
