The Amplivox MityMeg S602 25 Watt megaphone uses revolutionary piezo dynamic technology to make it lighter and more efficient than conventional megaphones. As a result, the 25 Watt S602 has an effective range of up to one mile (1,760 yards) while weighing only 2 pounds.
Piezo dynamic technology also helps the S602 draw less current than traditional megaphones. This means that its 8 C cell batteries(not included) can handle up to 40 hours of continuous use!
The S602 features a pistol grip and weatherproof design, and has siren and whistle modes in addition to talk mode. A battery indicator light, a cartridge for easier battery insertion, and an adjustable volume/gain knob are also included.
