Zello is a free app for smartphones that turns your phone into a 2-way radio (walkie talkie). Unlike radios which are range-restricted, Zello permits group communication anytime and anywhere you are connected to the Internet. Popular with emergency personnel, it enables group communication over vast distance if necessary.

​

We have a dedicated channel on Zello reserved for real-world SAR only - "Drone Search & Rescue".

​

We have another channel for training and chitchat - DSAR Training.
