Uses include schools, fire marshals, rowing teams, fetes and fairs and vitually anywhere that needs you to be heard. Due to the power saving, this one operates with eight of the AA batteries to save money and weight (see options).
The power levels of megaphones are confusing as it is the build quality and the amplifier, where fitted, that controls the sound level. This model is a very good quality and has three settings of voice/off, siren and whistle (more of an electronic screech!) along with a very helpful battery indicator.
Suitable for fire marshalls, building sites, temporary cover, hotels, schools
Note unlike most megaphones, this one is also particularly good for indoor use as well as outdoor
