OUR PART # PMP20
With each iteration of flagship megaphones, we've improved the battery life, power and ergonomics. This model has 20 watts of power, so your voice will be heard in ¼ mile range. Comes equipped with Voice and Siren modes. Voice mode amplifies your voice as spoken into the microphone and siren mode amplifies an alert / siren tone through the megaphone’s speaker works great for indoors or outdoors.
