The BT-PTT-ZU Mini PTT was coined the “Super Mini,” this small wireless switch flawlessly activates the Zello Push-to-Talk (PTT) Application on Apple devices and the Wave PTT Application on both Android and Apple for a hands-free experience. Because the BT-PTT-ZU uses Bluetooth Low Energy Technology (BTLE), it’s guaranteed to work for up to 2 years on a single charge with no charger required—simply switch out the coin cell battery! Pryme has developed 3 different packages for the PTT-ZU: The FOB version has a hook for key rings, while the RING version can be worn on a finger or attached to other objects, and the VELCRO version has a convenient adjustable strap, which can be affixed to steering wheels or any easily accessible location. The BT-PTT-ZU has been a valuable asset for law enforcement agencies during major events, but is also suitable for a myriad of uses and applications.
